monya Posted August 8, 2020 Report Share Posted August 8, 2020 having hard time getting to idle at anything above 10 ish afr i have a monsoon g4x, 2jzge vvti with turbo, deatschworks 700cc injectors , using traditional fuel model. when i have have master fuel to 8ms its super rich at start up 7-7.8 afr once it gets warm it idles at 9-10.1 afr and has fairly good afr for rest of the map, when i try to turn down fuel, master fuel to 5ms, fuel table all the way down to 5 for idle cells and still rich at idle 10.5 afr is just a little better,, its as high as i can get it tho, and at that point theres definitely not enough fuel in rest of the map at 5ms, even with cells right after idle at 70-80 will fall on its face going lean 16-19 afr, Quote Link to comment Share on other sites More sharing options...

Adamw Posted August 9, 2020 Report Share Posted August 9, 2020 It looks like mostly your accel fuel dead band too low so accel enrichment is going crazy. You can see in the pic below your TPS delta is around +/-10 at idle, so I would suggest set your deadband to about 15-20%/100ms. You should also update firmware as you are on a very old version that has seen many improvements and fixes. Quote Link to comment Share on other sites More sharing options...
monya Posted August 9, 2020 Author Report Share Posted August 9, 2020 so i have updated firmware and changed the accel dead band to 15% and now the car will not start anymore here is my file after firmware update and a couple changes to fueling to try and get it started, it doesn't sound like it wants to start not even getting a sputter 8-9-2020 2jz.pclx Quote Link to comment Share on other sites More sharing options...
monya Posted August 9, 2020 Author Report Share Posted August 9, 2020 update: got it started had to turn fuel wayy up, 18ms for master fuel and increased fuel table until it smooth idle at 13.8, was running better than ever and then just died, i think it has to do with my warm up or idle control settings, can anyone verify if i have contradictory settings causing to die right after start up ? was good untill i got to about 65c idle speed controll target was dropping from 1200 to 1000 if that helps 8-9-2020 2jz.pclx updated 8-9-2020.llgx Quote Link to comment Share on other sites More sharing options...
