ozzy Posted November 15, 2022 Report Share Posted November 15, 2022 Car drives fine however i am having lean spot(AFR goes to 14-18 different each time) after each gear shift WOT. Not always and not immediately after but around 5500-6000rpm 100-150Mpa MGP. It is showing on the logs but on the AFR gauge itself (aem uego 4.2) its perfect. Could this be an signal issue. Signal ground is connected to the expansion loom ground as Adam said in different topics couple of times. As i said before car rides and drives fine and that big of a lean spot i think i would feel it. She would at least misfire and hesitate but no problems with the car.

Vaughan Posted November 15, 2022 Report Share Posted November 15, 2022 Looks like you're hitting the rpm limit on each shift which causes a fuel cut which causes it to report lean (due to the missed ignition event), the lean patch happens about half a second after the cut which will just be a transport and sensor reading delay. ozzy 1 Quote Link to comment Share on other sites More sharing options...
