First I have to tell you I'm a noob.
My car is F20P completely stock and I flashed Stage2 EL E85 last week.
After read some thread in this forum I saw from somewhere adv multiplier should be 1 but mine is 0 all the time.

This is my data log from this morning.

What should I do to fix this problem?
Dose adv multiplier=0 is serious problem? and if yes what is the effect?
Please advise me.
Thank you

That is quite possibly the worst log I have ever seen. What fuel are you running? I'm guessing not ethanol?
Unless something is very wrong with the logging perhaps? Are you using OFT or Tactrix?

I'm running E85 and using OFT.

Ok while this log looks bad im almost 100% that IAM and FLKC ,MAFV are not monitoring/logging correctly so can be ignored.




The high LTFT initially in log are likely due to a recent flash or fuel change and fuel lines containing petrol and limited run time, they settle down quite a bit by end of log.


Looking at KC Learned it appears their is little or no knock as their are no jagged dips.




The higher rpm AFR is about 10% rich , that will not be a huge issue but will rob power and may cause some fuel dilution of oil over time.


The rich running is most likely due to the MAF needing a bit of rescaling.


are you on stock intake ?


other than the rich running, it doesn't look to bad as long as the ltft settle with a bit more run time.

Yes, I'm on stock intake. I will try to give more run time.
Thank you Steve.

Thank you Steve.

ok, looks like some maf scaling and a switch to a rom id that's compatable with your car but that logs correctly will solve most of your issues.

Thank goodness, I'd have a heart attack if I was logging and saw IAM=0

haha
, yeah I think if iam is actually 0 then it goes limp mode.


on oft KC Learned seems to log correctly most times so you can derive iam from that

Hi all,

Another noob here, from UK.
Because of my light flywheel (7kg vs 9kg OEM), I feel the off-the-shelf OFT stage 2 tune is not doing very well (had 200+miles since flashing the tune).

I've got a road log here:
http://datazap.me/u/thornad/log-1498...=1-2-4-7-11-13
and a track one here:
http://datazap.me/u/thornad/log-1498...=0&data=1-4-12

Would really appreciate your thoughts on this,

Thank you

What issues are you having? Also, what fuel are you running? You really should be running no less than V-Power or Momentum99 on a stage 2 type tune.

Lots of knock by the look of it, AFR a bit rich I think, but not sure, this is why I was looking for an educated opinion.
I'm only using Shell VPower.

Yep that prety normal for USA based oft tune on euro or australian fuel.

go to the first post in this thread if your A01G rom and just downlaod the A01G zip file and flash the A01G 98 UEL stage 2 map from their its the rich version but should solve most of your issues, if its still rich wot all thats needed is a tweak of the OL maf scaling over 3.4v.

If your not A01G pm me and ill help you out

just did my 60k service and my dealership still didnt update from 700I, dont have any knock though. am i correct if i use the non-hacked cal id Stg1 A01I rom from OP and the latest github A01I definitions i can update the ecu to A01I with tactrix?

I flashed the "Stg2 UEL 98 v111.2.AU.Rich A01G.bin"
I am MT. Do I need any other changes? Is the tune ok for MT as it is?

Thank you

I believe that the OFT tunes are based on the A01I ROM, so yes you can do that.

My A01I Definitions
