ECM upgrade (1227730) for stock 2.8 (Page 47/107)

Thanks Darth. It does look exactly like the one in the first post. So far I seem to be in business! Now to just figure out a crank trigger upgrade for the 2.8. (without pulling the motor for a crank swap)

Anyone happen to remember what page of this thread that the car list that these came in was posted? I've only got a few minutes of internet time a day and was therefore hesitant to go digging through all 12 pages myself.

lol - nope...but, I think it was within the first 3.

but - over all - I think the easy way is to look for alum headed 3.1 MPFI engines - the ones with the wide flat upper plenum.
tho - these wont have the right code mask - unless you plan on DIS also.
finding a distributer based one is not an easy find. in my local u-pull-it - I have only seen ONE V6 firebird.....and it was to new...was also DIS....

if you look on the back of the connectors, you will see the letters. they are on the outter corners.
but, the confusing part is the new connector. the "G" is the yellow one. the "B" is one of the 2 black ones. once you spot it, you'll see. bright light helps

Just a heads up for DIS converters. I just found out that a place makes CNC machined external universal crank triggers. The are going to be making more available shortly. The only way (so far) I found to get them was the 60*V6 store for $130.00. I am e-mailing them directly to see if they are available at other places also. The guy from this place TCE was very nice to me and responded very quickly.

awesome.
just so y'all know: the only extra wire you need to run for DIS is in fact the crank trigger. the existing 2.8 distributer wires are EXACTLY the same - you just move them to a new connector. and, use the power wires from the EGR solenoid for the DIS power, since the 2.8 EGR solenoid is abandoned with the 7730.

Please explain!
I have the SFI 3400 stuff in a box in the basement.
