...$58 and $59 has been used with '7727 and possibly with your 1619____ ECM part number, I'll have to see what the service number is that Lucky used in his Land Rover on his Toyota engine, with $59. I'm at the point now, were I just need to be pointed in the direction of how to determine what pins ...

k, Im not finding the quad driver diagrams for the Typhoon like I was for the Vette on Alldata. As for the 58 mask on this ECU Im all for giving it a shot, as long as doing so wont toast it, lol. But I imagine that as long as we assign the correct wiring to the correct ouputs, we will be ok. I see t...

since it looks like you have alldata access, compare a 92 Typhoon ECM diagram and the diagram for your corvette, you'll see what is different quickly. i made a cross-reference for it, but it is based on a W-body application originally using a 7727 or 16149396 originally... not sure how much you cou...

<<<DELETED>>>

So, knowing that the ECU's are electrically identical (7730 and 7727) just different connectors. How do we determine what pins are needed to confirm or deny compatability to the 58 stuff?

Here's what I found for the 7727 ECU pinouts. They appear to be the same connectors based on the illustrations. Hopefully we'll find that the 58 stuff will work for my existing ECU. Or worst case scenario, that I can swap to this ECU and get her going. http://i119.photobucket.com/albums/o142/JDaniel...

I found that the 1227727 ECU is internally the same as the 1227730 except in a weather proof housing for the TPI vettes. It also has different connectors than the 7730. I gather that you guys use these (1227730) ecu's because they are already speed density based and are not intended for use with a M...

I can get pinout schematics no problem through alldata, is that all you would need to confirm?

Is the compatability just a matter of what the ECU has pins for? If so, email me the comparable pinout and I can compare... Or I can just post up the alldata schematics here.

Hmmm, found that for 59 at least its not possible without changing to coil packs and a crank trigger. Think Im gonna go ahead and try to use the spotty resolution and VE tune with a 2bar and the DA2. Wonder if there is a way to add rows and columns to the tables with Hex editing. Even without added ...

If so... 58/59 compatable? I read somewhere someone said all you need to do is load in the files and change some code from 6cyl to 8cyl for it to work. But others say it wont because the cy/ty's have coil packs??

Moates.net says the Part # is 16159278 for 92-93 vettes. I'll look for a 122xxxx type number on the ECU itself tomorrow.

Thanks!!!!

On the moates site, I found info saying the 92 -93 Vettes used the same ECU part number, they are just listed with DA2 for 92, and DA3 for 93. Id really prefer not to swap ECU's if I dont have to... As I do not have alot of spare time on my hands with work and being a single dad. Is it possible to j...

<<EDIT>> I found info concerning doing this with a 93 ECU, but I dont know if they are interchangeable. (DA2 vs. DA3) Also I found the above mentioned info on Code59, but it appears most are swapping to the actual $58 ECU (the sy/ty one) and northstar coils. I really dont want to do that if its not ...

K, I have the AutoProm package, G1 adapter, and 27sf512 chips to use in my 92 Corvette. I tune all the time using HPtuners and the standalones, so some of this is confusing the hell outta me. I do not work with chip vehicles for income, just wanna do some cool stuff with my personal ride. This setup...
