Hey Guys
I am doing an engine swap on my 95 S10. It's a 4.3 TBI Z motor, 4L60 2wd. It has the ALDL connector with the ECM behind the glovebox. Some refer to it as OBD 1.5 which I'm not sure is accurate but it's not OBDII and not a flash code either.
So not sure if this matters but the engine has a linear EGR valve and a pair of knock sensors, one on each side of the block.
I am swapping a 95' K1500 Suburban 5.7 engine which is TBI as well. My issue is the EGR and knock sensors. The 5.7 has a vacuum actuated EGR and a single knock sensor.
Since the bolt pattern on the EGR valves are different I'm either stuck trying to figure out how to wire the vacuum solenoid in or deleting it. I'm in NH so inspection wise it doesn't matter and I don't really care of it's in place. But if I delete it I would like to do it right and get the software so I can delete the trouble codes and deactivate it within the tune.
Any input on what to do with the EGR and knock situations?
Also, my engine did not come with a computer. I bought a chip on eBay which I'm hoping will work. But I'm unsure if it will work correctly if I bolt the pair of V6 knock sensors onto the V8 or just retain the one V8 knock sensor.
