Just as it says gents, is there anyone that is doing this as I need some info and guidance as I will begin tuning for my Superram 383 very soon.

Thanks

 

Talk to 5SIZ. I won't touch anything with a MAF.

 

Why ya gotta discriminate now!!! LOL Actually I was hoping someone local had a programmer and a Moates cable I could try out before dropping the cash into em myself. Tuning the computer itself I got covered.

 

I built the Moates cable for my 91 and have the laptop, but I don't have naything for the 87. Sorry.

What would the difference be? I have a laptop to use, how hard was building the cable?

 

Medium difficulty. The little IC chip was the tough thing to find. I ended up ordering it online.

Thing is you don't have to build the max 232 one (the one I built), you only need to build the 2 transistor one. In 90(?) GM changed from the 165 to the 730 ECM which effectively changed the baud rate (among other things) and so the Speed Density cars need the IC chip design. Yours would be real easy to build!

 

You can get a "free sample" of the MAX series chips from most semiconductor companies.

 

Free sample? I dont know anything about the cable. Is it expensive to buy the parts? How long does it take to make? All info is appreciated?

85-89 wouldn't need the IC chip. Only the 2 transistors, 3 10k resistors and the diode listed on the diagram. It's stupid simple.

90-92 need the chip, as the 730 ECM has a higher baud rate and thats what the IC does, it steps the signal so that the serial port can understand. I think I get 7-9 data chunks per second from my ecm.

Thats the link to the diagram. Go to Radio Shack, get a 9 pin serial connector (female), the 2 transistors, the 3 10k resistors, the diode and a 4 prong (male) hard drive power connector (the pins fit in the aldl port very nicely). I can solder (barely) and I made the other one (max232) with the IC chip with a little help from a family member.
I might be able to help with the soldering, but I plan on having a VERY busy week next week. Let me know.

 

What does that sell for? Like 100$ right? People are nuts if they actually shell out that kinda cash!!! I will be making my own.

Esams and I plan to get together eventually. Gonna let him put his HSR on at the garage if he wants so he has full use of air tools and the like. If it works out for everyones schedule maybe you could supervise as I build the cable. LOL!!!

Peace
Mark

 

No problem! He knows I have air tools and a garage as well...

 

Sweet a bunch of fully stocked garages!! Now all we need to do is find someone with a programmer, already spent too much on tools. Regardles of if and when he installs the HSR we still gotta get together as my car should be on the road within a month, camros are cool but Im gonna need some other birds to fly with.

I have a pocket programmer and have been tuning my TBI engine before I killed it. I will be tuning my stealth Ram 350, using an Ed Write custom as my base. I could burn the chips for you if you gave me the bin and a chip.

PS: I have air tools too .

 

I forgot to ask, what program are you doing the tuning in. I have tuner cat, but not the definition file for 7730 ECM.

 

JR305

I could probably help you out with that def file.

maybe we should all get together one weekend for a test and tune. I would love to see what I could get out of the '5550 before I go to the '7747.

 

OMINOUS 87,

I have a similar setup as you do. If you guys end up meeting somewhere, please post it so that I can meet you and the rest of the local 3rd gen guys.

 

Well there is scan and tune in the works for some time this summer. In a couple of weeks my car will be on the road and the motor should be broken in within a month after that. In the meantime Eams and I plan to put together everything we need to test, tune, and burn chips. Our plan is to grab enough guys to rent out a local chasis dyno for a half a day which is about a 4 hour block of time. At that point we will use the WB O2 on the chasis dyno to tune WOT spark and fuel for max ETs.

Anyone who is interested respond and eventually I will put this together. Right now we have a laptop with Craig Moates software and Datamaster along with TunerCat and TDF files for all TPI computers. The only other stuff we need to round out the tuning hardware is a EEPROM Burner and a Craig Moates software cable. If anyone has this stuff and is willing to participate that would be totally cool, save me and Erik a few bucks. Oh, I have the knowledge to properly modify the .bins and tune the spark and fuel tables along disable EGR, higher idle, etc...

Let us know.

 

what will it cost to rent out the dyno?

 

I have the cable for SD cars with the ECM 730. I also have a laptop w/ Moate's software.

I would like to get a couple minor tweaks madfe to a chip (od and fans) so I'm interested.

 

If you're just going to the chassis dyno to use the WB O2... I'd suggest pooling the money and buying a WB O2 instead. You get to keep the tuning tool in the group, which if you've ever burned chips... you know it's not a one day event. I don't think 4 hours on a chassis dyno is nearly enough time to burn a decent chip, even for only two people. You have to include the time of tying the car to the dyno, etc...

Buy a WB O2 sensor, and rig up a location temporarily (In the cutout, etc.) Get a couple wires with alligator clips to put on the battery for powering the heater in the sensor, and one wire you can run inside the car so a *passenger* can watch the O2 while you drive. I spent 3 weekends doing 5 mile laps around a side street, a hill, a long straight road, and the interstate just to get my BLMs +-2. My WOT tuning was does at the local drag strip.

I get 24 MPG average city/highway. Which includes a day at the drag strip.

Edit: And I wasn't using WB O2.

 

Synapsis

A WB O2 is not required for part throttle tuning so that can be easily accomplished on the street with the stock O2 and yes tuning a a speed density car does requires lots and lots of time along with patience. As far as building my own WB I was actually planning on doing this but the price of the WB sensor has just sky rocketed up to 588$ nationwide. As for tuning WOT at the track this is not an option for me as there is no way to log accurate info on AFR without a WB O2 and I just plain dont feel comfortable rolling the dice with the 5,000$ and countless hours of build time I just put into my Superram stroker motor. So off to the dyno I go with or without a group.

I plan to use whatever shop has a mustang dyno with a WB O2 at the best price per hour. I imagine the price will be about 80$-100$ per hour.

Thanks for offering up the cable! Not sure of a date yet but well plan to see you there.

Well
