this isn't thirdgen related, sorry if that's a problem. but i am wanting to find out what bin and ecu files are used/needed for a 94 s-10 with a 4.3. i haven't pulled anything apart yet to look at the ecu or anything but if any one knows off hand, please share with me. THANKS!

 

There were 8 different pcm/ecms used in 94 on 4.3s, what vin code, and ecm number are you playing with?.

 

ok, i pulled it apart today and checked the numbers. it appears to be a 849, someone wrote that on there in pin. i did get more numbers off of it though if 849 doesn't sound right to someone else. it has the letters BDYT in about three different places, i assume this is the bin, right? also, what kind of chip would the stock one be? (so i can try to read it on my burner) any info that anyone can offer me would be great! thanks!

 

does anybody have any info that they would be willing to share with me? also, what programs would support whatever mask is used for this setup?

 

The BDYT is the .bin file your running.
It matches one of the listings for the 16168625 PCM.
I'm pretty sure that it's a 27256 type eprom.

 

Grumpy, i really do appreeciate the info you have given me! i have a couple more questions that hopefully you or someone can answer for me... what mask does this use? what .ecu file do i need for it? and what aldl programs will read the computer (and 160 or 8192 baud)? thanks a ton!

 

All the later ECMs, and all PCMs use the 8192.
The only mask I see for it is the E6.
The only editor I know for that is the one from Tunercat.
