hello

I finally flashed to bm3 stage 2 91 OCT with HFC DP. The throttle response is much quicker than stage 1 without hfc dp.

but the log looks not very good. maybe the oil quality is too poor here in Shanghai, China.

here's the log:

WOT at low rpm isn't a good idea. In fact you got a knock at 2'000 rpm, pedal to the metal and then a lot of timing correction. I suggest you to flash ACN91 map, that is specific for low quality 91oct fuel and use a booster octane.

You definitely need to get better fuel or use the ACN91 map. You're getting knock and excessive timing correction. If you continue to use this map you will surely damage your engine, I would suggest reverting to the ACN91 map and then log again.

thanks for reminding. Maybe I should put 95 RON gas for 91 OCT map.
I used to put 95 RON for stage 1 91 OCT which is fine.

I flashed to ACN map today. The log looks better but it's still not perfect.
Please check it again. thx.

The 91 octane rating is for the US system; so yes you should be using 95 RON to be equivalent to 91 (RON+MON)/2.

It seems a bit better but you should contact bootmod3 support for analysis.

yes. I already sent them the logs and they updated a CHN91 map for me as the gas quality here is so poor.
And they also asked me to log the stock tune. Here are the results from stock tune. I'm very surprised to see that. The only mod for my is a hf air filter and hfc 200 cel downpipe.

So, with stock ecu also did you get dirty logs? You should try booster octane

I change to RON98 fuel now. The log now looks much better on CHN 91 map which is made by PTF.
But I'm not sure why there is always boost pressure deviation between target and throttle.

hi how long did ptf reply you with a new or modify map? as I'm having trouble similar as you, so far 2 days no reply from them.
