Ok just got done doing my single turbo setup. When I started it turn out good besides my coolant light comes on! Which that I might be a bad sensor? So back to my fuel problem I take the car for a spin and started to get to 4500rpms and my car bugges down and for some reson it won't let me build boost. Also another thing my aftermarket fuel pressure gauge doen't work! So please someone help me or guide me in the right direction!! I also looked in the forums and no luck yet!

 

What are you running in terms of engine management? Also, what have you upgraded in your fuel system?

 

I'm running an apexi fc ecu with the commander and for fuel 1680 secondaries, 550 primaries, aeromotive fpr, 255 walbro fuel pump.

 

Well you have alot of problems here.
FIRST THING. GET YOUR FUEL PRESSURE GUAGE WORKING.

NEXT GO GET IT TUNED WITH THE NEW TURBO.

 

That's the point! I'm trying to figure that out. Tuning seems to be challenge! The closet tuning from where I'm is like 12 hours! So I
had Jason from rx7store throw on a basemap for me and I know its not the best method. So that's why I came for some expertise. So aleast help with my fuel gauge!

when it's bogging what's the AFR? You do have a wideband on it right?

 

Yea do have one it read 16's! Which seem to lean?

 

yes. in vac you should be tuning it to ~12-13 AFR, and in boost you want to start bringing it down to 11's by full boost. Go get it tuned
