Fuel Over Run issue, map and log attached

[K20a2tuned]

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 to get any movement, car would the. Be jerky and misfire.

This is a time issue, off throttle for more than 5-6 seconds it does it, off throttle for less time and back to throttle no issue.

Does it at 1;40 on the data log. everything is wired correctly, weve tried everything from fuel overrun disabled and enabled to different settings etc.

You have a VBU voltage high error. I would recommend that you correct that first before trying to solve this issue.

Do you have a MAP sensor connected?

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.

I've not heard of anyone else using a K-Pro having this issue, but the VBU error is not something everyone else has. That needs to be resolved first in order to determine if it has something to do with this problem.
