Chevy & GMC Vans

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,

Look over this place, good info....

7747 ECM's are readily available and cheap.

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....

Thank you;

I will check it out when I get back from vacation

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
