Hesitation/Fuel Cut on light throttle with ITB Setup!?

doc · Post by **doc** » Sat Mar 28, 2009 3:07 pm

I have problem on a Lotus Elise with K2x+ITBs. It's a race car. KPro is configured to Alpha-N. Car is tuned so far, no problems (back with 1.3.4 after the terrible buggy 1.3.5.x versions)

The only problem i run into with KPro is, on very light throttle, in gear (car is rolling) it runs into the fuel cut. This happens some times up to 3000rpm!? It's just annoying when rolling on the trailer or through the pitlane :(

TPS is calibrated. IACV is enabled, and connected.

And, and when you add some features, TPS-Tipin would helpful on ITB's and some NA builds, too.

It would be good to have more control over the fuel cut parameters. Like total disable, min TPS, RPM cut/resume ...

PS: sorry, no calibrations and datalogs, it's a customers car.

fuel cut is on the redline. your describing what sounds like lean cut/protection.

why dont you run a MAP sensor?

I'm seeing something very similar, would like to know more about this as well.

Thanks,

Without calibrations and datalogs showing the problem, it is impossible to know what the problem may be.
