I got my AEM installed right infront of the high-flow cat, @ the y-pipe.
It doesnt really read good when I start it up, it reads "---", or goes crazy.
The instructions say "Connect to a switched 10-18 volt power source utilizing a 10Amp fuse" for power (+). I tapped into my fuse box on the drivers side. I used a 15Amp fuse. Could 5Amps extra make my readings off?
My readings stay mostly around 15.3:1
Sometimes as high as 18s!!!
So, it seems that tuning Cpen & Closed loop could get me better MPG (if I could set it at 14.7:1 AFR).
The only problem is, under my Editor, on the "Open & Closed Loop" tab, there is no way to adjust it. The only options are Closed loop delay and the temp for when closed is enabled!!!
Any help is greatly appreciated!!!
