Hi guys,
I've installed a SMC+ and a set of 450cc dsm injectors, and I'm getting a code 45 (rich or lean) after around 50km. All my settings are at -40%. Is it normal ?

And i noted that i'm going in the rich zone when i should'nt, like when i just touch the gaz pedal (verry low throttle).

My DSM's was'nt cleaned prior to use, is it the kind of symptoms i would get ?

Thanks

are you tuning it with a wideband? (i hope?) if so, what are the readings.

Plugs reading and A/F ratio. I did'nt realy tuned it yet, only the idle is tuned to make it smooth. I should go to the dyno soon and use a lambda.

My plugs are perfect brown, but my A/F ratio show rich for a few seconds (and closed loop behaviour) when i'm at verry low throttle, then go back to open loop in stoich area. When i'm at full boost and WOT the car is pulling hard, and stay in the rich zone.

anyone ?

I get this code once in a while. Usualy when I am accelrating (boosting) at part throttle.

You are probably running too rich. You should tune your car on a dyno with a wideband.I was running way too rich at high rpm. I gained 50whp.
