Went to the local Pull A Part yesterday and pick up 9C1 injectors and ecm.I have a few questions.I want to put the parts in my 92 Roadmaster Wagon.
1 Do I need the ESC or any other sensors from the Caprice?
2 The service No.on the ecm is 16136965 and the code on the prom is AYDP 4623 are these correct?

3 Do I need to chage the base timing? fuel pressure is set at 12psi

What CID is your engine?

Fuel pressure should be fine as that was the GM setting. Better Q is your fuel pump adequate?

 

It's a stock 92 350 cid only mods are cold air intake and took the air horns off the top of the tb and made ajustable regulator.I have a 670 Holley unit I picked at P.A.P. for 20 bucks and a LT1 cam that I wanna put in when I get some time. As far as the pump it seems to be all right.The link you posted seems to have a lotta info the only problem is that I'm not at that level yet all seems pretty complicated.

 

The cam require a tune.

 

Yeah that's what I've read my one buddy has done some data logging and the sent the data out and had chip burned.It would be nice to find someone local to tune the car

 

Good to see you over here tork!
