popping under rich condition
 

hey,

i'm working on tuning my car with a apexi neo (referencing pressure signal). i'm able to get the AFRs at WOT to what i want; but when running half throttle or so it makes and underhood popping noise (i;ve never heard detonation but thats what i would imagine it to be) at the point this the AFRs are rich (10:1 or richer) which doesnt make any sense to me and the boost pressure is less then 8psi. timing is set to factory specs, also running rtek1.8 so some timing does get pulled above 9psi.

thing pulls like a rocket at 15psi lol

perhaps a Rich misfire, can you log the event and post the datalog?

i have no data logging stuff. thats what im guessing is just a rich misfire

you got stock plugs on there?Try all 9's.

its got all 9s

Plugs you must check, tell you much, they will.

the electrodes from the leading plugs are all rounded off, just wore out?

i wont really be able to test it much more this year anyway, i need a new driveshaft (u jounts crapped out) and i need to get tires for my DD for the winter before a driveshaft for the toy
