Ve fuel table maxed out

Recommended Posts

Hello, 

I have a 90 civic ef with d16a9 turbo with 1200cc injectors, 255LPH HP fuel pump all new. My duty cycle on the injectors is low 30% but the ve is maxed out at 150. 

From my research on this forum it could be a fuel pump issue. Beside the fuel pump what else could it be to cause this issue. Can it be some parameter in the ecu i missed, any help would be appreciated.

you maxed out your fuel pump...

do you use trandional or modelled equation ??

if its trandional your master fuel needs a lower value but thats not your problem here i just mention it

Im running it on modelled.

I only made 207whp and 192trq at 7psi, so that means my pump is bad. The pump is good to about 450whp on pump gas and brand new. I never had a walboro 255lph hp arrive bad, man that sucks. 

Thanks for the help

Can you post just your map then? Its entirely possible you have the injector flow rates set wrong or something with batch fire mode that is halving the effective injector pulse value.
