Fitech issues

MIne is a single turbo 5.9 with the 1200 PA. I have the MSD knock off with phasable rotor. Pump is an inline AEM 380lph on a relay, battery in the trunk. I never touched the PWM setting. Base timing is 20*. I bought an extra cap and put a hole in it to help me phase it. Wires from the distributor are shielded but I never had an idle problem before they were shielded, just an occasional fault code.


Your build was what made me chose the Fitech instead of going blow-thru. I’m running the 600pa. With FiTech’s 340lph e85 pump. I wanted to leave that option on the table. My setup is very similar to yours if I remember correctly. Stock bottom end re-ringed and new bearings. Hughes Eq magnum heads 2.02 with bowl work. You are on the turbo I’m on the Vortech. Cam is a.525” lift 113lsa custom grind for boost. My distributor is the cheap 50$ one that doesn’t take the msd caps or rotors. That’s why I question the distributor.

How much did you have to play with the idle screw. Mine is trying to idle at 400rpm.


Definitely going to try some of all your recommendations. I can’t get and shielding locally that would look half way decent. I have some at work I can try temporarily. Its an aluminum heat sheathing. Used for protecting lines running near exhaust. Thing is it’s abot 2” in diameter. I’m definitely going to add some more ground as right not the only one is at the frame by the battery. I’m going to move the fitechs main power to the battery terminal.

What gauge wire did you use from the battery I used 2 gauge. Mounted a 3/8 battery stud with 4 ga running to the starter. Put a 200amp resettable breaker near the battery. Next thing bigger at work is 3/0 which is overkill. I might get a piece for the ground to the frame then 2ga off the frame to the motor.

Hopefully the winter weather will hold off. They are calling for 8-12” of snow and ice over the weekend which isn’t good in N.C.. hopefully I can give you an update soon.
