Hello Guys, after installing my AFR Ratio i got some Troubles because my Car runs way to lean. Car Idle Cold - AFR 13-14 Car Idle Warm after driving - AFR 18 (WTF!) Chill Drive 80km/h 4th gear - 100km/h 5 gear - AFR 14-15 Fullthrottle - AFR 10 I got a S13 with CA18det and the typical Stage 3 Stuff. GT2860, 444cc Injector, Z32 MAF, 3" Turbo with 200cpi cat, open Air Filter, Walbro Fuel Pump and so on. Thinks i have checked: Stage 3 chip from noname to H-dev Stage 3 Fuelpressor Regulater changed Leaktest to my Intake Leaktest Engine (i probably here some noises but i think thats the Valves) Lambda Sensor Watertemp Sensor all Hoses at the Intake side after all it runs the same heavy lean so Nothing changed a Thing. I also tested my Z32 Maf Signal. In Idel i got 1.2v-1.3v out so it should be ok. Any Ideas what it could be or could be tested next? I want to check my fullpreasure next but in case that the Car runs fine out of my Lean Problem, i do not know if there can be a Problem? I really Looking for some help. Thanks Guys
GT2860 might be too large for that chip, have you asked H-Dev if it would be ok? Have you cleaned and flow tested your fuel injectors?
If you belive it or not but i was thinking About the GT2860 if it Maybe too large today. Only because i saw my stock GT28 from my S14 and was thinking About testing it if the is some better performace to my AFR. Funny I will email H-dev About that, good Idea. Fuel Injectos was on the plan but no, not tested till yet. Thanks for your help
