It's been 10+ years since I've played with my Moates OBD1 hardware, I'm a bit rusty! I now see Moates has closed : ( I am having a mental block on how to setup my APU1 to data log my AEM Wideband. I...

Hey all, I'm picking up a 3300 V6 powered 1991 Cutlass Ciera this weekend and wanted to play with the ECU, I'm bored ; )
Does anyone have an XDF for one by chance? I'm going to try and use a 3800...

Thanks Dave, I was hoping to not have to buy software, but at least we know it's an option for him.:thumbsup: Still holding out hope there might be a free xdf floating out in the internet somewhere ;...

Gents, a friend is wanting me to goof with his 1991 FWD Cadillac with the 4.9. I've only ever tuned 7730s, 7749s, etc. I can't find an XDF for the 4.9 cars (or perhaps I'm blind). Anyone able to...

Thanks for detailing your progress with this Phil. I will be building this exact combo this year (93 TBI with T-5) to replace a tired 2.8L and want to use the 16168625 for a few reasons. I had yet to...

I have actually seen this combination in the wild at a junkyard! It was an old 1994? fleet order truck for a power company. 3/4 Ton, 8 lug wheels, TBI 4.3L V6, and an NV4500 in all of it's huge...

Thanks for the reply 6 shooter, However, the Flash-n-burn did not work. Same issue...

Is my APU1 just dead after ~15 burns?? :mad1:

Gents, I need some urgent help.

Out of the blue, I cannot write, read or erase correctly any of the chips I put in my APU1 using Tuner Pro RT. I have tried 4 different 27SF512 (all of which...

Thanks for all the help Gents,

Ended up getting the engine running well (and emulating in my other thread). To the best of my knowledge, the block grounds for the main wire harness that fed the...

Gotcha, thanks. When trying to emulate, I was getting it to verify. I then initialized and it said that it was emulating. But then again, I still can't connect once keyed up. No CEL with key on...

Yeah, I hear you. There is/was absolutely no chip in the AutoProm and she fired and idled but was not getting any data. So then I checked the Autoprom connections and said wtf the ribbon cable...

Well we got the 3.4L running in the Vega last night and we were able to do a break-in. We did this by burning a chip. However, now we're trying to emulate in order to calibrate on the dyno next...

Thanks for the replies. Once we fixed the ground issue and tried the fresh ECU, everything was functional. The old ECU was smoked for sure.

Thanks guys, I'll make sure to take a look over everything again. I probed all of the connectors last night to make sure, and all the grounds and power feeds in the right locations. I'm just...

Hello again,

Thanks to those who helped with my questions last time pertaining to a friends car I'm helping setup. It's a Chevy Vega with a 92 S10 2.8 v6 and stock control system.

Anyhow, the...

Just a second thought, is there a newer ECM you can think of off hand, that I would be able to use with his TBI harness, but with a much better code base, larger tables, etc?

I appreciate the insight to my stupid question, haha!

It seems as if a lot of the knowledge on these ECU's is scattered throughout the internet, and not just in one place. The day everyone...

Hello Gents!

Recently picked up an Auto-Prom and have been tuning a 2.8L LL2 V6 from a 1992 GMC Sonoma, swapped into a Chevy Vega. $4E mask, 1228062 ECU.

Anyhow, the car is used to road race,...
