EP3 K20a Euro high fuel value problem

Post by gacksen »

Hi there,

have an Euro EP3 with RBC 70mm 2.5 midpipe standard back box and Tegiwa intake.

Just confused about my fuel values in my cal. Did several street runs to see whats going on
but my car is going out of puff in 6th gear. Checked with several other kals online here but nobody
is running such high fuel values. checked with my wideband the AFR values and they dont seem
to be that off the scale. Maybe the stock back box is limiting or something else ? did already change
the fuel filter and injectors or maybe the fuel pump is already on its way out ?

Maybe someone of you guys can check ? and help appreciated.

What do you mean by a back box?

back box = rear muffler

From the datalog I can see a little portion where the short term trim is +25%. The injector duration is pretty high too. I'd consider measuring the fuel pressure and perhaps a wideband to see what the lambda is.
