Rough running with updated FICM

[sonic blue l]

I think you guys need to estabilsh a base line.

To do that you will also need to know what ficm version you had stock. The first inductive heating flash worked well at combating sticktion, however it supposedly causes ficms to fail. (hard to say for certain as i've replaced bad ficms that never had the induction strategy in the first place) Ford then came out with a softer ficm strategy.

Lets say you had a truck that had sticktion so bad it would start and stall, if you updated it with the original ficm inductive heating, it would usually fix the concern. Now lets say you program that truck with the later updated ficm strategy, well now it still starts better then the start/stall, however you will have misfires when cold due to it not combating sticktion aswell as the original inductive heating strategy.

So now if you had the early inductive heating or have a ficm with the original inductive heating and comparing to php ficm with the later inductive heating, then your not comparing apples to apples. Now if your ficm was the later inductive heating and your comparing to the php, now one can do a proper comparison.

BTW personally i feel your truck should run great before you start adding or reprogramming as if it does not, you may just be compounding the problem.
