Question for you Lemmi experts............

ImolaRocket · 01-26-2005, 10:27 AM

My part throttle LTFT's are -14 and -16 percent with the 5bar FPR. I want to keep the 5bar in to keep the O2 voltages around .85-.87 at WOT. Does one of the fueling tweaks in Lemmi address the part throttle issue, but leave the WOT fueling alone??? Am I making any sense???

I did not like them that low, so I re-installed the 5bar....Hence the question about Lemmi. The car pulls much stronger with the 5bar and a little more boost (19psi spike, and about 16 at redline), but the part throttle LTFT's are a little high.

It's like he has super duper stock injectors or something. Maybe he got RS4 injectors from the factory ;ppp

You should not need to make any fuel adjustments with lemmi when stage 3-.

Just not sure which of the fuel settings in Lemmi would be the correct one.

Just trying to cover my ass, and keep the motor well fueled.

Honestly, your car never made sense to me. I don't understand how someone can flow 300+ g/s on stock injectors and 4bar with negative LTFTs.

Have you driven around a bit with the 5bar so it can adapt?
