Hi,

I have tried to tune 8E0909518AQ file to EV14 550cc injectors and have few question about locations and factors.
Could somebody check and correct these if something is wrong.

KRKTE 1FA18 , factor 0.000167  this should be close based on logs

TEMIN 14DA6 , factor 0.002667
TEMINVA 14DF6 , factor 0.002667
TVUB 14E00 , factor 0.002667
KVB 1B44E , factor Huh?

Based on logs the 0.002667 factor is near correct but based to this factor should be 0.0040

Also when i change TEMIN on 14DA6 address its messed something on checksum area because Winols could not anymore correct it and car would not t
start after firs startup.

ME7sum and ME7check could recognise and fix the problem. After fixing with ME7 tools car works fine, but Winols shows 2 checksum wrong.

Hello

KRKTE and TVUB is at the right location.

TEMIN is at 14D58

So the stock value with factor 0.004 is 15.0560ms?
I am quite sure it's wrong address.

There is too long time since i last time use IDA.
Cant remember how to adjust IDA info to OLS to get maps right.
This is what i manage to build with that info.
Does it look right?
