Closed loop makes my engine stall

Post by Christophe1976 »

Hello,
I need help, I'v a H22A with a AEM wideband serie X, my tuner cannot get the engine to work in closed loop, when he tried the AFR rise above 25/1 and the engine stall, in open loop the engine works, the AFR is correct (between 14.7 and 15) any idea why it does not work??

Thanks for your help

Christophe

How exactly do you have the wideband connected?

Two threads, a light grey and a dark grey arrive on a pod, then the brown thread of the wideband is plugged in and a light grey goes on the D1 of the S300

there is a white threads who come from the wideband and it's not connected.

is it correctly connected for you?

I see scotchlocks and they should never be used, as they do not provide a good connections and can actually sever the inner wire and cut the signal. I really cannot tell anything else from that picture
