short story. removed my ls1, built a iron 6.0 added 243 heads (fully ported) and a brian tooley cam adv duration is 277 287. 613 .576 lift. and bought a ls2 intake used off craigslist w/ injectors. modified harness for injectors and map sensor. fired it up on the stock 2001 ls1 ecm. i have done everything I SEE to bring my afr down at idle. i havent even gotten past idle yet in my tuning experience. i was able to make it idle by increasing target idle speed and base running airflow which i learned via youtube. not sure that this is the correct way because everyone elses hpt file doesnt have setting anything like i do. my start up afr is in the 10s maybe 11s. i have taken my ve map to as low as 10 thinking lets make it run lean after all small changes did nothing. i also dropped my ve cranking map lower and even took my open loop eq ratio to 1.00. all with little to no change. last i took my floe rate vs kpa to 28.5 rumored that my injectors were 28.5 maybe i was supposed to make a change in thereryans ls1 tune mod latest.hpt
