anyone who can help.. it would be appreciated.. I don't know what's up, I've bought everthing I need to burn chips. I've even copied my stock bin and put it on another chip and that works fine but no matter how much I read the light isn't going on as to what the items listed in the bin file are for ie. "which line do you change if you put in 24lb injectors". I've read and searched for injector contants which everyone seems to say you need to change BUT I don't have a line that says INJECTOR CONSTANT.... and lines I do understand like initial spark value make no sense with numbers like 80.96..
I've also read those are binary numbers and you have to multipy by x and subtact
y and so forth but where do you get the x and y numbers ect. to come up with a real world number. Is there a book or article that will tell me what each of the listed CONTANTS, FLAGS and TABLES. are for and how to reach real world numbers..or is anyone in Florida that might want to make some money training a newbie. Any help appreciated

 

A) What are you working on (ecm/mask wise)?.
B) One or two specifc guestions atta time.

 

Grumpy, If I understand you question (A)., I am using GMECU edit that I downloaded from this site to try and edit my bin to make sure it is set for 24lb ford injectors. and then slowly work into ajusting the ve tables and then spark advance. However I don't know what to edit to make it right for the injectors and am not able to make sense of the spark tables.

 

For what car?

MAF or MAP? TPI or TBI? Auto? Stick?

Using what ECM?

With what mask? (ei $58, $6E, $32)?


Give us some info man!!

 

This guy needs to know the injector constant is the place for setting injector size,mask doesnt matter it's a common table.

 

Sorry,

92 GTA 5.7 liter,
7730 ecu
map and auto.
Is mask the same as definition file?
I read mine is 8d,, is that something I
have to use or is that only for tunercat?
Hey I really thank you guys alot for responding and trying to help!

 

As a reference, in Winbin you will find it under the "values" tab, scroll down and look for: Single fire FI size and below that : Double Fire FI size. That is the injector constant, make both lines with the same value.

 

Sorry, another wrong response by KVU/87400TPI/Formula5/guy./grumpyx. You DO need to know the calibration as some use BPW which works differently than an Injector Constant.

 

Morley,, I don't have anything that says Single fire F1 or Double fire F1..

Glenn91L98GTA.. I do have a Base Pulse Constant.. Is this what I would use to set the injector size? It says 184 .... what does that mean or how would I come up with the right number to replace it with if I'm using 24lb ford motorsports injectors?

 

It's actually an Injector Flow Constant if you use TunerCat.

But the whole method of using it as a Base Pulse Constant is far more difficult, especially since it's really a "16 bit" double byte that you are dealing with.

The actual address it uses is 841C and 841D.

Rather than try and explain EXACTLY it's calculated (and why) which will most likely confuse you, I'll just give you the "conversions" in decimal and hex (which):

Inj ...... Dec ..... Hex
22.1 --- 460 ---- 1CC
24.0 --- 423 ---- 1A7
25.0 --- 406 ---- 196

 

In GMECM edit you are looking for this.

 

In an *old version* of GMECM edit.

But yes, it will be in the "constants" list in GMECM Edit. Load the ecu for your car and look for it.

what *.ecu file are you using to edit your bin?

 

Yes, and if he had a $6E MAF car. But he has a SD car.

 

Well, since thats what I use that's what I can provide an example of. I notice no one else even went that far for the guy.

 

naw, i'm not flaming you. you're awesome. =)

 

Tried going to the FTP site to get the mask and a bin, but it is not responding, is it down?

 

What? I gave him the actual converted number in hex and decimal for 24 and 25# (and anything else he may wish to try).

I could easily paste a picture of TunerCat too, but that's not what he's looking for ... he want's that the constant. Geesh.

 

Huh? Engrish?

What he appears to be asking is where he inputs the injector constant for his new injector size. Just like I put up there.

 

Morley, I think you better re-read the question he asked me.

He wanted the constant to equate to SVO 24#s for the $8D/SD calibration. When he quoted "184" this is the hex value for the Injector Flow Constant for 26#s (A common flow # assumed for SVO 24#s).

I gave him the answer in both decimal and hex for other values, which is what he asked for (for his $8D). He obviously doesn't have a better Bin Editor (at this time) or he'd know to just plug in the "Injector Flow Constant" in #s, not "hex".

Papaford, get a more uptodate bin editor and one that uses "Injector Flow Constant" not "Base Pulse" or any other editior that requires working in hex. And make sure it's for the $8D and nothing else. You have an SD car.

Morley: Drop the word "that" from the phrase your quoting...and stop posting pictures of $6E for $8D users....it just confuses people - they aren't the same nor do they look the same.

 

I did re-read it, a few times and this statement tells me he wanted to know WHERE to do the changes, along with how to calculate their hex equiv.


"which line do you change if you put in 24lb injectors. I've read and searched for injector contants which everyone seems to say you need to change "

 

EXCUSE me for trying to help the guy, it will never happen again.
Is that good enough now?? :hail: :hail: :hail: :hail: :hail: :hail: :hail: :hail: :hail: :hail:

 

Whatever. The poor guy is confused and you aren't helping any by posting a picture of a calibration that has NOTHING to do with his SD car.

Have you ever worked on an SD car or tuned an SD calibration?

 

papaford, feel free to PM me any time. No need to wade through this egotistical crap to get the answers you need. Morley was totally on the right path. i'm embarrassed for the rest.

 

Yes, have you?

 

come on guys. thats enough. you're both awesome and everyone has respect for you both. please, i plead, move on! you're making us *all* look bad.

 

New maf only board

Bet you got more than you bargained for with this post Papaford

You did get the first part of your question answered, but I can't see the second part attempted, so I'll rush in where angels...

>>how would I come up with the right number to replace it with if I'm using 24lb ford motorsports injectors?

There must be a formula to calculate this from scratch, but the answer is proportional to cylinder size/ injector size (flow rate)- some of the ECU's have Litres/g-sec. I haven't ever been able to get the number to work out directly from this division, but if you know the injector size that was used on the BIN you're starting with, you can multiply the (decimal) injector constant by (OLD INJECTOR SIZE)/ (NEW INJECTOR SIZE) and you'll have corrected for your new injectors.

It would be nice if someone who knows how to calculate this from scratch posts the needed info.

John

PS it would also be nice if kvu/87400/etc picked a less inflamatory name than grumpyx. I was going to suggest another of the seven dwarfs' names, but that may have looked like I was flaming him

PPS Morley- great illustration of the general principle. Please don't give up.

 

Thanks everyone for your inputs,, right or wrong I appreciate the help. I do have SD though so my bin file in GMECU edit looks different than yours Morley.
Glenn ,, you said get a more up to date
bin editor. What do you recommend I'll get it today.. Also you said one thing that really confused me.. you said:
"he quoted "184" this is the hex value for the Injector Flow Constant for 26#s (A common flow # assumed for SVO 24#s)."
Well 184 is the number used in the stock AUJP bin ... shouldn't that be the number for the stock 22lb injectors?
Finally John: thanks for your info.. I believe I came across that formula last night.. but I don't know how to get the decimal value..I have the hex value or the calculated value to choose from.
Big thanks to everyone I think I'm getting closer, but not quite there yet.. Probably my fault for not understanding everything your trying to relate to me....Dana

 

Just as I figured. You ARE working in HEX.

You don't have the stock AUJP bin. In that location, the stock AUJP bin has "01CC" in bytes 41C & 41D. What you have right now is setup for 26#ers (basically 24# SVOs @ 45 psi).

Look at Magum's recent sticky post on his new FREE Bin Editor. Hex is TOO HARD for most people to work with. I use TunerCat for this type of work normally (even though I have actual Source Code for my BIN).

But, you may want to scope out TunerCat now that they are releasing an interface for the Romulator. Rather than "burn and test" for various sizes of Injector Constants. You can just adjust the Injector Constant in Real Time and keep adjusting it until you get most of the BLMs hovering just above and below 128. Much faster and way simpler. Sometimes it is better to invest a little money rather that do it "the hard and slow way". Your call.

I would be suspicious of that BIN your are using though. It is definitely not the original AUJP. If you need a known good AUJP, I have the latest GM released version of the AUJP (1615). Unfortunatley, www.thirdgen.org will not allow me to attach those anymore.

 

Hmmmm

 

Oh get real. What have you done to help the poor guy? In a word, NOTHING!

You got Morley here confusing the poor guy when the guy was asking the proper hex code (like I said). And you offering nothing but stupid snide remarks like some punk jerk "know-it-nothing" under 25 year old.

Why don't you trolls go back to your little website and talk about all the "great projects" you are dreaming up (but never do). And stop arguing with us older 40-50 year old guys that actually know the correct information because we've actually done it and not just dreamt it or talk about it in our arm-chairs.

PS: I love the lack of information at www.efi-tuning.org ... Lots of "questions" and "in-progress" but nothing concrete. Why not do some actual work instead of pretending you have, and then fighting with us guys that HAVE done the work (and trying to stop this misinformation you keep spreading).

Now get lost.

 

Your not ***,get over it

 

papaford if you need it here is the link to TunerCat, it's a really nice program to have and is easy to work with.
http://www.tunercat.com/index.html

 

Or, for free, you can simply continue using GMECM Edit. Which is lacking none of the features of tunercat.

 

Dana,

The "calculated value" that you have is already a decimal (base 10) number. You'll note from the numbers that Glenn posted, that the ratio between the injector size and the Decimal numbers is the same in each case. That is, if you go up from 22.1# to 24.0# injectors (ratio is 0.92) you go down from 460 to 423 in IC (ratio is 0.92). Do the sums for 24# to 25# and you'll see it's 0.96

The thing to have in the back of your mind is that bigger injectors or smaller cylinder size make the IC go down (because the IC is proportional to Cylinder Size / Injector Size.

And Mangus' GMECMEdit is the best thing since sliced bread. Free bread :lala:

John

 

somebody sounds jealous

 

Thank you everyone for all your inputs...
I figured out the promblem and I now have numbers that make some sense to me.. I was being really stupid and using the wrong ecu. file.. I was using 730 instead of 7730... So now I begin the process of tuning and logging... thanks again to all.....

First off efi-tuning.org is my board, yes it's new and a work in progress. I'm sure this board and any other board didn't start fresh with 10,000 posts with all the answers. I'm very interested in this stuff and quite frankly am sick and tired of the smart *** comments on this board. There's nothing here anymore than arguments and cutting people down. This new guy here just had some questions and this post like many many others turns into useless crap. There are alot of talented people on this board but a select few seem mostly interested in cutting people down, too bad. I've not tried to advertise it on this board and have asked the mod to delete the post that did, I'm just trying to contribute to a subject that interest me and i find this stuff very cool.

 

lock please. papaford's question was answered.
