FiTech EFI system

UCUDANT said

I have only heard the 6AL making noise with the key on eng off, and only have a few miles on my set up.
I believe we did also see things like the RPM data etc move with KOEO as well.

I will start by shielding everything together without separating any of the FiTech harness, as I don't want to void warranty (I've had it a year before installation though)
Then if I have any issues I will contact FiTech and then proceed form there at that point we might be helping with resolving issues and they may ok and stand behind the alteration.

Update: Got an email back from Bryce at Fitech.. May be my problem.

"The wiring that I have seen cause random RPM at key on is the oxygen sensor. If you disconnect it and key on will RPM stop bouncing? We have a way to stop this in the software."

I have emailed back asking if the software is something I can implement. I"ll report back after I test this by unplugging the O2 harness, and turning key on, later this afternoon. If true, it looks like the O2 wiring harness needs to be shielded, and mine runs right beside my distributor pick up line.

Fingers crossed!!
