FICM with Atlas 40 Tune is Awesome
Tired of rough idle on cold starts? Tired of losing injectors every year or so? Check out your FICM with Autoenguinity or something else to determine if it is going below 48 volts EVER. Mine was going down to 43 and bouncing all over the place, rarely reaching 48. Talked to Ed at FICMrepair.com after discussing the issue with members in thisn forum. Got a rebuilt FICM from Ed with the Atlas 40 tune because I want to still tow my race car and the Atlas 80 and Hercules make towing more difficult due to higher EGT and I have stock tranny and converter and the higher tunes are hard on that too. Put it in last night and on cold start this morning (36 degrees without block heater plugged in) it started and ran so smooth it was hard to imagine. Also, my low end power is significantly higher, which is great for my 71mm billet wheel turbo. It bridges the gap with tht turbo on the low end. I can't say enought about it so far. I am ditching RevX because it only lasted 3 weeks and is simply too expensive to fizzle out that fast. Hopefully I will never need it again.
