How To: Ditch EFI and keep TBI PCM for 4L60E Control.

[siggy_freud]

Well we have a 500whp 06 Saleen Mustang, and 450whp 335i, so if I ever need to get my power fix, I can. Not saying I wont want that type of power in the Camaro, but just don't want to put the money in at this point. I just want some good MPG outta my DD. Nova sounds nuts though .

hey fast orange i saw you just used the factory fuel lines, did you have to do a restriction in the return line to keep it from bypassing the carb and just flowing to the tank?

And what kind of pressure does a edelbrock 1405 need

No, the purple & white wire is for the stock pcm tack signal. If you are gonna use the pcm to shift the trans you will hook that wire to the tach side of the coil. If you are gonna use a aftermarket tach you will also hook the wire to the tach side of the coil. If you are gonna use the stock tach then you will hook up the green wire to the tach side of the coil.

 

[gimmel1]

So I hook them to the same point on the coil
