Fan on, engine bogs down
after a few months of using the Fi-tech system I am only having 1 maybe 2 issues:
1st issue is when my electric fan (not controlled by Fi-tech) kicks in my RPM drops like 200 say from 800 to 600 RPM just for a second until it recovers while the fan still runs. which leads me to my second issue.
2nd the idle is set at 800 RPM to accommodate the above drop in RPM. I would like it set to 650 RPM (where it was with my carb).
Also, I have a new battery, 160 AMP alternator and all suggested ground wires.
Does anyone have any tips?
Thanks

I would recommend the fan be controlled by the Fitech. A drop in RPM makes me think you might want to look at your wiring. Power your fan relay directly from the battery. Fitech direct from the battery. And over do the grounds. My method.... 2ga battery to block, 10ga battery to body and 10g battery to frame.
