Re: Stutter/Hesitation when going to full throttle

Interesting, thanks. Time to go back to the tuner I guess.....

Re: Stutter/Hesitation when going to full throttle

Thanks for the input. Could it be that the rich condition is being caused by the flow restriction of the supertrapp muffler we added after the car was tuned (it is running open loop)? I will pull the muffler and do some more test pulls to see if that corrects the AFR issues you identified. Oil press...

Re: KProV4 - TPS and o2 Sensor Issues

Turns out the 2 problems were related. The TPS was installed incorrectly, so it wasn't giving a proper signal. Once the TPS was fixed and gave a reading the o2 sensor started acting normally.

KProV4 - TPS and o2 Sensor Issues

Hi, I have a KPro V4 installed on a PND ECU, running the K24 in my Miata. We received a base tune from the guys at KMiata, and have the car up and running. Sort of. We got the car to idle, warm up, drive into the trailer and into the exhaust fabricator/dyno tuner's shop. Pertinent details: Brand new...
