Hey guys, got a VERY small issue im chasing and im hoping someone may be able to help out.
I have a 2018 Mustang with JT Vortech kit fitted, 1000cc injectors, full exhaust.. Can performs / drives well makes good power.. However have a very small issue with cold start (ECT below 25 deg Celcius) I cant seem to get enough mixture in the inital start up and it gets a lean miss until the 02s fire up and grabs it..
Ive tried:-
Inj Adj low slope slightly
MAF A/F vs Period (trims LT / ST are no more then +5.0-6.0%) in this area of start up
DI / PI blending Cold & Start up
Fuel Base Cold (pulling down to 0.96 Labda)
Once it gets to 30+C its fine..
Any thoughts.. Just chasing the 1% to make it spot on really.
Happy to PM / email file to anyone that can help
