Re: Turboe'd but Rich!!
Well I bet this is a joke but anyway. I'm suprised your car even started with 450s and an fmu dude.
You probably have a gallon of gas sitting in your muffler right now waiting for the right time to explode!
the 450cc injectors will make a car run rich on their own because their about double the size of stock. And then with the fmu your adding more fuel.An fmu has no way take fuel away it can only add it when it's told to.
You at least need an electronic afc hack. but they suck to.

Re: Turboe'd but Rich!!
The problem is that you are running 450cc injectors with an FMU.
An FMU increases fuel pressure to increase flow, therefore you do not need larger injectors. You are giving your engine wayyyy too much fuel.
Swap out the 450's with your stock injectors and it will run better.

You should probably retard your timing at the distributor to. If you have a motor that you can adjust timing at the dizzy anyway.
I read about an accord turbo project on cb7tuner.com where a guy just ran an fmu and then fully retarded the timing at the distibutor and his car ran fine for over a year I think until he could afford to go with uberdata.
