Car has a custom loom, and has done 3 24 HR races with that code. That's not the issue, yes car has a map sensor, and it's plugged in, it's located in the backing plate.

Hello guys,

We believe this to be the problem but just want confirmation as we can't test before race day.

Car is a stroked 2.2 running ITB's with carbon plenum and Kpro V4.

We were testing 2 days ago and every time at two hairpins on the circuit the car wouldn't go and ignition had to be cycled ...

This is the setup. Map sensor is placed In the backing plate taking the reading from the Carbon Airbox.

Car runs great, idles perfectly.

laps perfectly except for when we drop below 4000 RPM.

The calibration is linked above the two images if you're able to view?

Thank you.

Plugs were new and are now white, that's how we knew it was lean.

Thanks for taking a look. Never had an issue like this we can't pinpoint. Feel like we've tried everything.

Hi guys,

We've struck a bit of a problem with our race car and was hoping someone could help on other things to check.

Just a bit of back ground, we tested and qualified and engine was fine, quicker than previous and pulling well.

After qualifying car wouldn't start and battery was drained ...
