Guest clipguy Posted September 10, 2014 Share Posted September 10, 2014 greetings, fellow supra brothers. i am from malaysia. would like some keen advice from fellow supra lovers,I am currently driving an aristo jzs161 with a 2jz vvti. recently changed to a single turbo setup. due to my previous turbo was leaking. currently having irratic low idle(~600). during acceleration when let off gas pedal revs tend to drop very low, with occasional stalling. i have since tried the following : 1. changed new maf sensor 2. changed new map sensor 3. recheck coil packs and wiring( changed connectors as well) 4. installed new fuel pump (walbro) 5. installed new fuel regulator (sard) 6. extended the distance of the maf sensor from turbo intake. 7. custom 3 inch (stock size) afm housing. 8. changed pcv valve and hoses 9. checked for boost and vacuum leak 10. currently using ngk iriway 7 spark plugs 11. installed emanage ultimate ( idle issues and stalling still apparent, but boosting seems ok) 12. installed new battery 13. installed new o2 sensor 14 am currently using a MINES ecu. ( it came of a basically stock half cut) 15 swapped and cleaned out a working throttle body using a standard obd2 connector i have been monitoring the LTFT , mostly has been negative at idle sits at -3 and with acceleration sometimes goes down to -7. i am at a lost into what might be the problem. hope u guys can shed some light. included is the dyno chart and an engine bay picture Quote Link to comment Share on other sites More sharing options...
