VersaTune User Forum

Hi guys hopefully you lot can help. So I've installed my Versatune today, uploaded the high load map, covered about 30/40 miles since like the guide says but now I've come to calibrate the MAF using the Versatune Excel Spreadsheet but my car won't read below 1.14 volts on the Mass Air Flow Voltage so how am I ment to get the readings for all the voltages below 1.14 volts?

Any help is very much appreciated and if anybody is free some night this week an lives near either Stockport or Congleton and knows how to calibrate it completely then I would appreciate some help.

No worries. The engine is never under any real load at that MAF voltage anyway. Just calibrate the operating range that you can log. You may want to manually extrapolate/smooth below 1.14v if you see a big jump from the first logged data point and the points below.

Ive attached the logs I managed to get from tonight. Hopefully this is good enough for somebody to possibly be able to fill out the Excel spreadsheet for me so I can add it to my Map.

Here are some logs I took tonight. $ of which are 3rd gear gradually building up the revs to the limiter and the other 4 are 3rd gear WOT runs.

Here are some other 4th gear WOT runs that I managed to get tonight.

Hopefully these logs will be helpful.
