Working on a Voodoo swap in a 68 Mustang.
The major changes from the stock engine configuration are new forged internals, compression ratio of ~11:1, billet OPG and CS, ID 1050x injectors and D1X Procharger at about 12 psi of boost. Fuel pressure is set at about 55 psi.
I have tried a few tunes and the engine will attempt to start but never fire off. What is odd is that the TPS is showing 26* during the attempted starts. What is even more strange is that it will start with the TB unplugged and continue running when it is plugged in. The engine will idle, but it is a high idle ~1200-1300 rpms. I have included that datalog below.
I have attempted the TB relearn by slowly cycling the pedal three times open and closed and on the third hold it open for 10 seconds.
26* seems to be too wide open at idle. And I find it strange that it will not fire off on a tune with the TB plugged in, but will start with it unplugged and idle with it plugged in.
Any thoughts? Thanks. Original Tune New ECM - TB unplugged at start up.hpl
