I'm experiencing high VE numbers on Idle it is at 83% ish, I didn't tune the whole table just trying to figure things out before taking the car to the Dyno for a full tune.

Running on 100% Ethanol, 1050ID Injectors, with 3 Bar fuel pressure, and have done the wideband free air sensor calibration too just to make sure.

Any tips on what to look at would be appreciated.

Hi,

I would look at the calibration for your MAP sensor as a starting point, you are showing 89.6kPa as a MAP and Ambient pressure with the engine not running. Unless you are tuning at 1000m of altitude, your sensor is out by 10% at engine off. If the slope of the sensor calibration is incorrect, this will also be feeding the M1 false data, leading to the VE table being out.

Hi again Stephen!

Yes sir we are at 950M of altitude here in Jordan.

On the old map I had a VE of 50ish on idle, but now the only change i have done is upgraded the turbo from stock CT15B to a Garrett g30-900. All the configs are the same as I had them before but this huge jump made me doubt the config abit.
