Quick Turbo Question

[Ryze268]

I read this forum post

Actually, it's a common problem that FIC users have if the unit is not setup properly. If your cam/crank sensor signal & grounds are not 100% and are noisy, it will cause the FIC to pick up a bad signal at higher RPM. Your symptoms will be difficulty revving past 3500-4500rpm and it's a common issue. The easy fix is to install a 2.2K(just a baseline, you might have to go higher or lower) ohm resistor parallel to the cam and crank sensor inputs and tie them into their respective grounds with the resistors. The good test for this is to run the engine NA (just undo the intercooler piping so the turbo can't build boost), and free rev the engine. It should go up to the 6500rpm stock redline no problem with just the stock ECU connected. If you hook up the AEM and do the same, but it cuts at 3000-4500rpm range, then you have the common faulty ground. Make sure all of the settings in the tuning cells are all set to 0 while you perform this test(this ensures that the FIC is not screwing with the signals).

Do you think that has anything to do with it? When ground these connections, do I have to do it to the ECU or can i ground them somewhere else?
