car is a 2001 olds alero 3400. lately ive been trying to get the aem afr gauge to read through HPT and can not get the darn thing to work im stumped.... ive gone through pretty much every thread and help page here looking to fix my problem with no luck. so I was forced to make a thread on this.
I forget the model number on the aem afr gauge I have.. but its got 4 wires. red, white, blue, black.
red wire - power.
black wire - ground.
that's what is making it work in the car.
then I have a white and blue wire.... well I ran a ground on the passanger side of car for pin #5 on the tuner and the neg wire seems to be stable to me.... then I hooked a wire up to the white wire from the gauge for power to pin #1 on the tuner. everything wired up go to hpt and add the input... check.... start car and it read a constant 12.78 to 12.79 would only change between .01 afr. while my gauge is reading 14.4-15.5ish in car. so I tried running the power wire from pin #1 to the blue wire. still no change in afr. went into hpt and configured my own afr with correct voltage settings for the aem gauge. still no change. im stumped idk what to do from here. hate to create another thread about this but ive literally looked all I can on here and other forums... and asked a guy helping me tune the car as well and he has ran me through some things that also didn't help.
I also went to thetuningschool.com and looked at there afr gauge hpt hook up. they used an LM1 afr gauge and it had a program where you could reset and configure the afr gauge.. well my aem gauge doesn't have that so I couldn't fully follow his video on how to set it up. please help!
