I got a FMIC i want to install but have a few concerns. I'm installing new Efini spec turbos on new engine w/ Blitz SUS Intake, DP and mazdaspeed Exhaust. My concern is My ECU...I still have stock. Would it be safe to do this upgrade without upgrading the ECU first???

 

Your new efini turbos (if they are 99 RZ) will not work correctly with the stock ECU.

 

I had 99 spec twins with the same mods as u basically with a stock ecu and it ran, but ran like garbage. It was incredibly rich and i had to run low boost, like 8 lbs so the stock ecu could keep up with fuel. Get a power fc or actually, i am selling my used pettit ecu for $450 which will work a whole lot better then the stock one.

Thanks for the help guys...and i was actually gonna get the power fc only i'm a little short on funds. On a seperate note, i'm currently trying to take my Transmission out and i'm having a hell of a hard time taking it out...i have no tool that fits in the tranny to remove the clutch cover bolts and the damn thing won't budge. Can they make it any easier to pull that out...Any suggestions would be great.
