It is the same dissy that was in the car with the single throttle body. It has come out and gone back in so I would assume the crip angle has definitely changed. I'm aware it prob needs fixing but when I was running the self learning ecu and the 8579 (mag pick up) the crip angle wouldn't have played a part? Correct but for the Motec it will make a difference
Do the efi dissy's need to be put in a special way (the mag pickups) or do u just need to know which tower is at tdc for cylinder 1?
No special way but No1 dissy tower needs to be correct. Turn the motor over to TDC on No1 (compression) and use the tower in line with the rotor button for No1 cylinder. then place the other leads in firing order sequence counter clockwise from there.If there is a reference mark on the block and base of the dissy, then align them.Assuming there was a refence mark made before removal originally. If the marks are not correct try rotating the dissy each way a little until the motor smooths out. That will get the CRIP close but you still need to check with a timing light and with the Motec ignition locked at say 10degrees to set the correct CRIP value in Motec (or rotate the dissy until the timing corresponds to the locked value in Motec)
Another thought, did the original TB use MAP referencing for load via a vacuum port? if so do you have a good vacuum setup on the ITBs via a common port. You will also probably see a little less vacuum on an ITB setup as well.
