go standalone and be done with it

i am using map ecu and i hate driving my car sometimes .. ecu always fighting in closed loop and eventually affects open loop ..tried to tune closed loop to match oem setting but someting always trips up and boom here we go again

i am either getting a aem by month end or pulling motor and doing jdm supra 2jzgte map based motor singled and tune with safc with a upgraded stock ecu for only open loop and call it a day

 

All you have to do is pull the narrowband. Basically throws it in open loop all the time. It took me a couple days to get the cold start up and warn up temperatures fight for idle. But it pretty much becomes a stand alone after that point, as far as fuel cells go anyway. I'm running the ECU 2 though.
