hi everyone...
I get my pwm in lastweek.
But my fuel trim max alone..and the ign adv is so bad.
I runing the RON 97 gas,Maybe its like the 91oct in US.
I have some logs in attachment.
My car is 2010 335i N54,30k miles.I have a DCI,BOV,DP,FMIC and the PWM.
But my car not fast...its so slow...
100km~200km@11.4s best
40mph-100mph@8.8s best
the first is "KMH"
the second is "MPH"
I change my spark plug and HPFP in 5/2012.
but its missfire frequent.and the code is "10700"
whats the 10700?

I'm sorry,because my English not very well...

Thank Reply

You must run MAP4 if you now have PWM Meth. Ensure you have "Methanol Mode" set to 1 and Injection Mode set to 25. Set MAP2 Start Boost @ 75% (For now, you can raise later if you get things working) and Start Ign Corr at 0%

When in MAP4, if you accelerate, you should see your turn signals illuminate if methanol is flowing. If you do not see the lights on, then you probably have air in your lines and you need to purge them before it will work.

Hope this helps!

Never run Map 2 with methanol injection - ONLY run Map 4.

You also must log Methanol Injection Flow, and leave out Methanol Injector %.

If there are any poor connections on the hoses to the methanol system, there can be air bubbles that cause poor performance.

Additionally, you should run Stage 0 to be sure the boost and ignition curves are not too aggressive for your fuel quality. 97RON can still have a very poor MON value. RON or Research Octane Number is not a good indicator of fuel quality for modern engines, and especially not a good indicator for turbocharged high performance engines. The MON or Motor Octane Number is more important, and can be very low for your fuel quality.

10700 is "misfire, several cylinders".

I'd reload the firmware and map to start. Then make sure all your settings are correct in the user adjustment window.

Exactly why I'd reload the firmware and map. No reason for the log to look that bad.
