I would like to know if someone can help me with my case ... So over a year ago I bought an ek1 lite from sxth and my original ecu ID was ckkn3tmd_h0a and they patched me to ckkn3tmc_h0a. My car was running good but had a lot of timing corrections. Someone told me to try the original file from another ID but since then my idle is funky . For exemple target idle is 630-650rpm but the actual rpm is sometime as high as 750-850 rpm (sometime it is really lean too and other times afr are normal...normally throw p0068 code after a few run cycles) . Last week it threw p0068 and p0507 so I removed the 2 map sensors and the throttle body to clean everything but to no avail. I flashed "recovery ckkn3tmc_h0a" then I tried "recovery ckkn3tmd_h0a" but nothing works to fix my issue... Would using a bench cable fix my issue? Why would some tuner change the Ecu ID in the beginning ? Should I just buy an OEM ecu with my original ID ? Thank you in advance

It was good for normal driving but someone told me that the timing calibration from TMD and TMC were really different (scared me) so I listened to him but I should not have donne that cause now even when I flash back to ckkn3tmc_hoa original the car seem to idle high and sometime the afr jump as high as 18 afr (car almost sound like it want to stall) . I cleaned the throttle body and the map sensors. But it really began when I tried to flash the other version. Is there something I could do to ? Thank you , I really appricate your help ! I ordered a bench cable from you this week , don't know if it will help me resolve my problem but I hope so . Have a nice weekend!
