dyno now I'm $$$$$$ rich $$$$$$
 

Went back to the dyno I installed a begi adjustable fmu and a fuel gauge under the hood to tune. Well last time I was at the dyno I was lean between 15 and 14 my fmu was not working. This time the fmu is working to good the best we could (6 pulls) tune or adjust the fmu(fuel pressure 45 idle up to 85 boosting) was at 4000 rpm its at 13 and gradually goes down to 12 at about 5400 rpm after that from 5400 to 5800 rpm it goes down to 10 and stays flat at 10 or lower the rest of the way to 6500 rpm. The dyno only reads to 10 so no telling if its going even lower. my hp 260 torque 230. Next step will be safc should be able to get it dialed in the rest of the way with that I hope.

do you have a AFPR to lower idle fuel pressure back to stock that could help with the richness

switch to a lower fmu disc.

Good advice too much FP, too much fuel, simple drop to the next smaller fuel disk. 10:1 is way too rich for a supercharged vehicle, 12:1 is perfect since boost is perfectly linear!

he has a begi FMU which dont use discs its rising rate is fully adjustable via a knob on the top just like a AFPR

He's get the BEGI (Cartech) fmu, so no disk.

You're going to adjust with the bleeder valve. Open it up a few turns and that will lean it out. You should try to adjust with the fmu as much as you can before resorting to the SAFC.

Here's some information regarding tuning with the Cartech fmu:

we did 6 pulls on the dyno adjusting after every pull. the bleeder valve is back all the way out and the center screw is in enough where at 4000 rpm its at 13 and gradually goes down to 12 at about 5400 rpm after that it goes real rich I think the safc is going to be my best bet I don't have a chip so the safc and the fmu will be my only tuning.

like jaime said in another thread: emanage if you dont already have the afc.

I don't have a laptop or know to much about computers I think I will be better off with the safc.
