GS300 and AEM FIC Install
It's either broken or you got maf in and maf out reversed at the patch harnes. With the bypass harness, it doesn't really check for any sort of reversed connections because the wires will conduct electricity no matter what. when it is connected to the fic, it will only send or receive in one direction. again triple check your connections or just even reverse it on purpose. who knows maybe it is I that made a mistake on the .pdf.
ok i checked wiring its good. i use the reverse harness and start the car, the car starts fine, vsv vsc and check engine light goes away and i can rev pass 3k.
when i plug harness into fic, the car can not rev pass3k. i see the maf in is at 4-5volts and maf out is 0 volts. <- i think this maybe the issue. but how do i fix this issue. it is giving me a headacce and i want to start tuning the car.
is my fic broken?
sorry i already splice my wires, lol.
tps sensor isnt messed up, the car runs fine in reverse harness.

isnt maf suppsose to be in voltage and not percentage
this is not a software problem, but a hardware problem.
give aem tech support a call tomorrow. they have a decent tech support because their products are 60% of the time, works all the time.

im kinda confused...cuz today i was hitting 10-10.5 AFR not boosting (it was right under 0 psi) and it was constant...(only for about 4 seconds) im currently untuned (except the base tune type stuff) and it runs great at idle and cruise...also about how much boost can the maf deal with?
thanks
thanks
ok..i need some input/help. all the sudden my AFR gauge says im idling at 13.8-14.3 and cruising at 12.1-12.6. is that too rich? nothing has changed..i checked my tune, and reset my ecu just in case...so im maybe thinking its the gauge...its the AEM wideband...has it been know to read rich like this?
Thanks

you are on the right track..but read this

(you might have to become a member..) post #26 download the first pdf and follow what it says about the crank and cam sensors. basically our cars dont use the MAGO- on crank or cam. follow the AEM instructions except tap (not intercept!) the negative crank and cam with MAGI- (the instructions say to intercept the signal with MAGI- AND MAGO-...dont do that lol) so just follow the pdf and the first part of the instructions...let me know if i wasn't clear enough...
