I'm dyno-tuning a customer car, it's a boosted Honda S2000 with an inline pro kit. It has a walbro fuel pump, 675cc injectiors, and a WG spring pressure of just 6PSI.
Here's my problem. I got a great idle and cruise map going, we even got into some boost on the street. Everything was looking good until about 7K RPM when things start to get lean.
I said OK, no problem, and stuck the car on the dyno. I adjusted the boost compensation tables and optimized the fuel map multiple times. The car was still running out of fuel from 7KRPM up.
IDC's go from 25% at 6.5K RPM and go to 58% IDC at 7K and it's still leaning out..
My question is, are there any hidden fuel tables other than boost compinsation, or maybe a second VTEC table in the AEM EMS.
At this point I'm 99% sure it's not my fault, and either the hose is popping off the walbro at high RPM, or it's a cloged fuel filter, or other mechanical issue.
Thanks for any help you can provide me, I can always count on SM when the AEM Forums down.
