Hi Hondata,
if i run my FN2 s/c on idle with or without A/C, the engine runs very lean at about +9/+13 s.trim, closed loop lambda is correct @1.00:
Idle and s.trim with A/C on:
Idle and s.trim with A/C off:
Is it possible to make the Idle more rich or what is a optimal idle-s.trim value?
Thanks!
Idle is very lean!?

Re: Idle is very lean!?
My Car is a FN2 with Rotrex C30-94 Supercharger and RC 750CC Injectors.
I have made a another datalog.
The idle you can see at the end of the datalog.
Please take a look on it!
The Map and Datalog see below!

Re: Idle is very lean!?
Has this been properly tuned on the dyno?

Re: Idle is very lean!?
It may have something to do with the manifold design. Have you discussed the issue with a professional tuner?
Re: Idle is very lean!?
I have the same kit mounted. With my old RC 750 injectors and the little 650s... Strim was 0 or little rich but never +10 or higher...
With my dw800 and the tts layout all good.
Did you have no idea what could be wrong? Maybe bad injectors, fuel pump, o-rings?

I found the issue for this case.
Deadtimes of the RC750kit which is mounted is unfortunately to high. (We used the deadtimes from your RC750 starting calibration but tests confirm that it does not match for this kit... Total creazy because other kits which I have seen working fine with your default values...)
So we are currently determine the correct value for this injector kit so we can say the idle + low load the S.TRIM values will be the same...
Update: MAF sensor is going bad... Adjusting the deadtimes does not fix this effect as expected.
First check with an other MAF - the readings AFMflow Volts are OK - new part is ordered...
Re: Idle is very lean!?
No, the problem was a leak (o-rings) of the injectors (manifold-sided).
The problem was solved with new seals together with new ASNU (customized) injectors!

The black pipe which is connected to the rotrex was not sealed completely which cause wrong air passed the MAF sensor...
After fix the air leak, XY s.trim vs AFM.c curve looks perfect.
