Help! Hitting a wall at 3.5K rpm
Well as the title says, Im hitting a wall at 3.5 K RPM. This is were I have set my RPM stage at. When I move this down to 2K rpm it wont rev past that number. I have read several things about staging but dont seem to get mine right. I have set it at several points but didnt help. The car is a FD with 850 Primaries and 1600 Secondaries.
The map stage is set at 5" HG. When I look at my wideband it will say when hitting 3500RPM 14 AFr than back to 10.8 (this is my safe tuning). Does this mean that Im still too lean? Or do I have a different problem I have a FPR 1:1 base pressure at idle is around 36 PSI. When I hit 3500 Rpm I have around 0.4bar 7 psi?? so that would mean a fuel pressure of 42 PSI. Anybody got some hints here. Wont be able to try them till weekend because my lambda sensor is broken. |
14 afr is lean. you wanna richen it up to get that number back down.

99% but it will do the same on 75% 60% and 50%
I know 14.5 is too lean. But thought It had something to do with something else. Can it be that the injectors throw in too much fuel? Or wont that cause bogging and stuttering. |
If your injectors were putting out to much fuel you would be rich, not lean. What is your a/f at idle? What are you tuning with? Hand unit, lap top?
|
Make sure the wires haven't backed out of the connector on the secondaries... It sounds as if they either aren't staging, or they are dumping a shitload of fuel in there.
|
When I put the ecu in test mode the Injectors are pulsing.
|
Im also tuning with the laptop.
