I'm here working on a eg with s300 and cpr. I put in 0 on the fuel tables and car is still idling at 10.6af

I'm thinking it would be the ecu or the injector driver but im not sure

0 the complete table not just a few rows and make sure you have uploaded the calibration to the ECU.

I put the numbers to 0 to troubleshoot.
Update:
I disconnected the ecu and removed the s300 board to inspect and upon installing it back I was able to get the af values to reflect my increase and decreasing of fuel.
