Misfire and knock count
Misfire and knock count
I just installed ktuner base map on my stock 2009 si. After a test drive it’s reading misfires in all cylinders as well as a high knock count. Any ideas as to what the problem is? Thank you
Re: Misfire and knock count
As mentioned in the description for the tune, you likely have an intake that's throwing fueling off. Talk to a tuner.

With factory or properly designed intake for MAF, sure. With the majority of the intakes out there, probably not without switching to the speed density option and consulting a tuner.
Re: Misfire and knock count
Assumed it is factory intake as it’s still covered by the intake box but I will check. So for the time being is it ok to run on the speed density tune or must I get it tuned immediately?KTuner wrote:With factory or properly designed intake for MAF, sure.

I'd recommend getting it tuned right away.
