I've got a 350 tpi with full exhaust and some other bolt ons but I can't even get it to spin the tires. Not even close. I set the timing to 6* before TDC and installed and new o2 sensor. It idles fine and starts up no problem but when I hit it it feels slower then my 305. I also had a 350 corvette prom with adjustments to the SA tables. Could my prom be the issue? I'm also throwing an engine code too. I thought it was from the o2 not being installed but once I got the o2 welded in I'm still getting a code. Any ideas would be appreciated. Also the tps is set correctly at .54 and is operating fine.

 

Pull the codes and post what they are.

 

OOOOHHHHhh. Talk to Utilityguy. He is the one who burned you the EPROM. Ill keep my comments as rated "G". Until then, I'm suscribing to this one.

 

I'm not pointing my finger at anyone just yet. Its throwing a code 24 which is the VSS. I didn't even get a chance to clear the code yet cause I tested it so late and I had to go to sleep but I'm narrowing in down to two things.... And then I'll let you know the problem. I'll be pulling the prom today too an ill post the numbers burned/stamped into it as well.

 

Its hard to tune a car without having physical access to it. Even if the tune is wrong it doesnt mean the guy is screwing with you. Just means it's wrong and needs to be tweaked.

 

You mentioned that you have a corvette bin burned right? What material is your cylinderheads? Cast iron or aluminum?

 

I don't know what you have against me but you need to stop the continual harassment! I've put up with you up until now but this one got you reported!

How do you know I provided John with a Memcal? Are you stalking me on multiple sites? Stop it!

 

John, What is the Corvette Prom you mentioned? Are you running Aluminum heads? If so the the spark tables need adjusting for a more aggressive spark. You did not mention that in the order. Also if you truly have a VSS problem that can cause all kinds of problems as the ECM doesn't recognize that the car is moving and lot of the programming depends on that. You need to make sure you are getting an input from the O2 or it never will run correctly. Sorry to post this in the public but since it was brought up here it needs to be answered here.

 

One other thing that came to mind was someone also had a problem with SLP runners. He found that the runners did not match the manifold and were leaking everywhere. Don't know if that helps but it just came to mind when I saw you also had the Siamese SLP runners. If you could get a BLM reading to see if you are running lean it would help.

 

That is the case the ecm does a diagnostic check a vacuum leak of or malfunctioning iac will case the vss error. The ecm think the car is moving. Does the speedometer work ? not sure if this is maf or map but the buffer would be working internally in the ecm or externally if maf. If no high idle or high lift cam this malfunction might need to be taken out of the code.

 

Utilityguy, I never harassed you in anyway, all I said was rated g. Where's the insult in that? All I told Whitestripes is to ask you for advice. I thought I was helping the guy by referring back to you. If you want a public apology, here it is,,, I apologies for any trouble that I have caused you. But still that isnt good judgment for you to assume that I'm harassing you or stalking you. Didn't it cross your mind that I said Rated G?????? Doesn't that ring a bell that I may have said that in a form of "me not making derogatory remarks"? Come on now. Let's keep it civil and let's act like adults. I've stepped up to the plate and publicly apologized. Now are you willing to step up and apologize to me for reporting me for an assumption based on our past??????

 

Utilityguy, might I add, I'm not stalking you. I posted on this thread before you even replied to it. How is that stalking? If anything, your attacking me for nothing. Here in this thread, Seems like your trolling me into trouble.

 

Apology accepted. What's done is done. It is my reputation that takes a hit when you question my integrity. I've seen where you actually give good advice so I know you have the potential to help others. So let's go forward and just try to help others with their problems and not question others motives. Thanks again.

 

You're correct! GM never made a F body 5.7 with manual transmission so there is no stock prom for them.

To solve that problem, I have taken a program for the Corvette 5.7 6 speed with aluminum heads which needed more aggressive spark and re-worked the spark tables to make it compatible with the F body iron heads.That is only difference and it works very well and is the answer to your problem.

I've sold many or them with great response.

Above is the pm you sent me when I was looking for a prom

That is the corvette prom I'm talking about. The one I assumed you sold me when I told you I was keeping my t5 in my iroc with my 350. That's why I needed a prom that would work with a t5 and a 350. Case in point -a corvette prom. Not trying to sound nasty I just didn't know how else to word it.
Also I'm sure my slp runners are not leaking. I've had that problem before and the car will run like absolute garbage and barely idle. My car idles fine and will cruise fine but just doesn't have the power it should. Not even close. There's really no need to argue. I'll figure it out soon and post my results.

 

Well, I tried but you had to respond in bitterness while I was typing my response.

UPDATE: We made up!

 

Sorry but what I said there was since there was no Bin file for a Fbody, that I used the Corvette Bin and replaced the SA chart with one for iron head tables. I was just explaining in a PM how I would accomplish what you wanted. It's not really a Corvette Prom after that. That's what confused me when all of a sudden aluminum heads came into the picture. I'm just trying to help you.

 

This is just curiosity. Not a stab. But is it possible to "copy and paste" the tables into another bin file? From my understanding, everything must be matched such as Torque converter lockup, fuel/air ratio, SA tables. But I'm not too knowledgable in this area. That I admit. Perhaps some insight into that area will clarify that subject.

 

In this case just the SA tables were changed to match the heads. And sure it's done all the time. Also this is a manual transmission Bin so TC doesn't come into play. MAF tables are very nearly the same.

 

You need to find someone with a scanner or data log a decent run to find out what's going on. Do you have someone nearby with a scanner?

 

I see. Thanks UG. As for camarorookie, he is right. Your best bet is to datalog and post up your findings as a word document so that an experienced logger can look over and give you some suggestions.

 

so i guess my idea is out of the question, I have a 87 ta with a 305 tpi, and i have a 89 gta with 350 tpi, (parts car).. i want to swap 305 to a 350.. is it worth the trouble.. one question if i do lets just say, do i have to change the computer box too..?

 

Lots of people don't change them especially with a MAF car. The injector flow rate would be off but you could boost the fuel pressure with a adjustable regulator to make up for that.

 

Chiming in. Im not saying that it's bad to use an adjustable fuel pressure regulator, but according to my TPI Fuel Injectors Guide by John Baechtel, it is not recommended. Here is a quote from the book "While it is easier and more cost effective to raise the fuel pressure, this is a mistake. Many tuners try this, but keep in mind that raising the fuel pressure more than 15% will usually skew the fuel curve enough to harm performance unless a calibration change is made" (page 42, side note).

 

If you really wanna do a convert, I would suggest you google 305 to 350 TPI swap. You'll find a link to IIRC, TPIParts.com and there will be a section that covers every single part that needs to be changed. I've heard that the ESC module doesn't need to be changed. But in my 305 to 350 swap, I went the whole 9 yards.

 

Update: I replaced my speedo cable because I noticed it was frayed and bam! No more code 24. I can even spin the tires now! Lol, but it still feels slow. It feels like my old stock 305. Not a mild 350. I'll mess with the timing this weekend and see how that goes. I feel like she dies at 4k I know these engines can't rev up to high but it souldn't be maxing out at 4k right? I have a feeling my cat. Converter may have welded itself shut because I was running super rich for a while. I'm not sure though. I'll keep you posted on the results! And unfortunately I have no way to data log my car as of now. I've been trying to get into custom tuning but whenever I try to read up on it I get sucked into a subcategory about tunning that's way to detailed and out of my league. Lol

 

Check the valve springs. I had almost the exact same problem. The crate motor I bought from AC Delco came with weak springs.

Comp Cam 981's are a pretty good spring for stock heads. I think I have a set laying around actually...

 

Like these? http://www.compperformancegroupstore...Category_Code=

 

Thats them.

 

Ive been having tons of issues fixed my main one cracked fuel line in tank replaced and regulator tps idles strong now alil high can rev the h*** out oif it in park but as soon as i put it in drive instant kill or reverse is worse its like it slams in reverse and dies instantly....its a 91 L98 350 in a 92 rs changed the kick down cable and ecm with swap ohh speedo doesnt work guages fine idk if there related also rebuilt tpi and manifold any ideas one please??? really need to get it back on the road and am at a loss on ideas

 

Not to be mean but you really need to start your own thread. You have HiJacked the heck out of this thread. Grammar is a plus too.

 

Sorry about that that really wasnt my intention i just figured this was the closest topic to my issues to find someone that would be able to help side not last hijack promise adjusted tv cable wayyy off but still same thing then i tryd unpluging the sensor on the trans in the front drivers side and the problem was cured, im not going to drive it like that of course but does this mean its a torque convertor issue? sorry agian about the hijacking you guys just seemed to kno more about this than any responses ive been able to get

 

I wouldn't rule it out but I got the engine out of a 89 firebird and it was completely stock. Im sure why the stock springs would give me such a problem. I'm gunna mess with the timing some more and get back to you. If I do replace the springs I'm going to invest in some 1.6 rockers. Any brands I should look into for the rockers that won't break the bank?

 

I run the comp pro magnums. Not cheap, but I like how theyre made of steel and have a large fulcrum.

 

C.C. Magnums are one of the most chosen for center bolt valve covers. There are self aligning and non self aligning. They run about $20 each. Not cheap. There are similar narrow body 1.6 rr but they are not self aligning and are probably china made. Skip White Performance sells these cheap ones. Many people say skip white sells good quality, but many say you get what you pay for. Sorta defeats the Mr. White has quality with cheap products.

Update!! So after hours of messing with the timing, idle, tips sencor, testing and retesting, I decided to throw in my old 305 it started right up idled fine an had more pickup then the 350 chip I bought. Needless to say I feel scammed after paying 90 bucks for a chip that ran worse then my original one. I could have saved myself hours of frustration as well as 90 bucks that could have put towards something else. I tried to give you the Benifit of the doubt but the results dont lie. I hope this isint the same experience your other customers have but if so your running quite the scam and it really isint fair especially when dealing with people on a budget like most of these thirdgen owners.

 

Someone in this posting said that you bought it from me. If that is the case, send it back and I'll gladly refund your money. I have 300+ customers that have never had a problem. If you bought it from me, I included a contact sheet that you could have used to work this problem out. Just give me a call!

 

Hmmm...guess I'll get my chip else where. Glad I saw this before I started any decent mods.

 

I'm very sorry you feel that way. I supply a economical very high quality product. There is more to the story than this posting. check this out. https://www.thirdgen.org/forums/dfi-...cals-sale.html

As I said, I have over 300 satisfied customers with lots of letters of appreciations and thanks.

 

BOOM!!!! Again your advertising your ebay link which is a VIOLATION OF TGO!!!!! Your getting red flagged utilityguy.
https://www.thirdgen.org/forums/cama...ese-rules.html

 

Someone sure has a woody for utilityguy. Seriously, you sound like someone with a serious axe to grind and youre grasping at straws for a way to get revenge on someone.

Im inpartial to this thread, but really, Ive seen fingers pointed and afaik, OP hasnt posted proof that he in fact ordered something from UG. I mean, I can make a thread that 92 RS Invader sold me a wiped cam. But if I dont have proof its just a baseless accusation.

From what I see, OP didnt give UG a chance to fix it. Mistakes happen. Especially when it comes to tuning. All it takes is for one cell or parameter to be wrong and you'll have all sorts of issues. If youre REALLY that concerned with getting a perfect tune the first time, you really shouldnt be buying a $90 tune off of ebay and you should take your car to a local professional tuner who has your car for a little while and tunes YOUR setup. Mail order tunes are hit and miss. Always have been, always will be.

 

92 RS Invader, I don't know who you are or what stake you have in this but knock it off! You have been flagged twice before for your threats and for stalking me across other sites. I have never advertised about EB. Those are some others on the site talking about me. Since you are a new person here, I have given you lots of leeway but no more. I believe you are actually someone else who holds a financial reason for the flaming and I have been in close contact with the board, so once again, Stop the harassment!

 

Hmmmm...breaking the rules, scamming people and getting angry and threatening when called out? I think it's time for a ban on utilityguy. He's caused too many problems and should not be exempt, especially with having ripped people off, as it seems a few people have evidence of.

 

Anybody got proof???? Have any of you personally dealt with utilityguy2?? If not knock this crap off now!! All I have seen here is assumptions so far, so quit jumping to conclusions. If someone has proof then lets see it and it can be dealt with then, otherwise consider this your 1 and only warning, next action will be probation. This is for everybody not just you jayhawk sorry if me quoting your post makes it look like I am talking directly to you I am not this is for everybody, I am not sticking up for anybody if that is the way this sounds. Lets stop the bickering and keep civil so this can get straightened out.

 

Fair enough. If anyone reading this has dealt with utilityguy and has had problems, tell us your story. If it is to the contrary, lets hear that as well.

 

We do have proof that thewhitestripes ordered from utilityguy though. In utilityguy's first post he said "you never mentioned that in the order."

 

I welcome the feedback Jahawk, I'm not quite sure of who he is as user names are different site to site but I have had no contact with him other than here, I took a guess as to the identity and from his response I think I know, but I'm not 100 percent sure. The only thing I do know for sure is that I try to help people not harm them. My offer stands to thewhitestripes, call me so we can discuss any problems you have.
I'll gladly put my reputation up against anyone's. 3Go is one of the best sites I know of with dedicated people helping others. These accusations bring everyone down and are not needed.

 

This is really getting out of hand. There's no need to ban anyone or burn them for their product. I will admit I was frustrated when I found out my 305 chip worked better but if your willing to work with me on resolving this issue then there really is no problem. Looking back I probably should have sent a pm to utilityguy but I did want to post my results regardless because someone might get some useful info out of this thread one day. Utilityguy, I'm wondering if just a stock 350 chip would work better even though I have a t5 and the 350 chips are all automatic. Maybe I could send mine back and just get a stock 350 chip from you and then post my results. Let me know!

 

Sure, I'd be glad to do that or whatever you want. I'll PM you so we can get the details worked out and I'll give you my telephone number if you don't still have the contact sheet.
