Hello all;
I don't seem to have the 7747 ecu, so I scanned it to see if I can still only replace the chip to a V8 chip, or if I have to replace the whole computer.
Here is the URL to it.

Thanks for looking. Any info is greatly appreciated.
Drive safely,

Re: ECU and chip replacement
look over this and see if your astro harness has the pins in the right place for the v8 computer, I learned this from the many v8 s10's I have done over the years....

Re: ECU and chip replacement
Kc, unfortunatly,that wont work for red/blue plug computer like in a 94 tbi,only for the older tbi computers.The 94's have the newer computer in them,I was just looking at mine and it didnt match up at all.So, I'll have to find another newer diagram
