after changing your load points your map will be off.

have a look at the the 2 screenshots you posted. for 100 load @ 2k RPM, your original timing was 17*, now after adjusting your load cells, your 100 load @ 2k RPM is 26*.

when you adjust your load/rpm cells, you need to also adjust your map accordingly. you cant just change the numbers and expect everything to work correctly as that will not occur.

basically the map values need to be moved in line with the load/rpm cell changes. that is, you need to move your old 100 load range to the new 100 load area. and do the same for the other cells that were modified.

then for the new load cells you created, i would start by interpolating horizontally and then go log and tune for better accuracy.

the same theory applies to your fuel map aswell.

cheers

For me to help you, I need you to reset your ECU, load the settings I gave you, let the car idle for 20 mins and then go on a 30 mins cruise, then report back the low and mid fuel trims.

Again, if you wanna fix your stalling issue, the first step would be to go back to a recirculated BOV.

Hi Boosted Tuning,
here is my latest Cruise log & Idle log for your kind advise.

Please note that the Latency values in Cruise log is slightly different (0.024ms each) compare to Idle log. Please refer to attachment.

Im sorry that the files is still over 100KB after compress so im unable to post my logs & map here...
