Report Tuners Rejoice! Free Tuning For M4.4! in Performance Modifications Posted July 14, 2020 16 hours ago, Dangerous Dave said: I get the same thing on mine, random MAF errors. Thought maybe the connector was dodgy but now you have the same issue I'm not sure. If you want to just stop the MIL coming on (error lamp disable in tunerpro) then you could add a new scalar pointing to 0xF39F (for the 608rev5b) and set it to 0. Otherwise, looking at the Damos there isn't a diagnostic disable for the MAF. However there is a min/max flow in kg/h for diagnosis and also a min/max RPM threshold for diagnosis. The mini flow is at 0xF239 and max flow is at 0xF23A. The min RPM threshold is at 0xF23B and max RPM threshold at 0xF23C. Thanks for the information, I've added the 4 MAF scalars to the XDF file, I think I've got the right conversion for the speed ( X*30 ) but I haven't a clue for the air flow conversion. I am I right in thinking for the speed diagnostic is between 1500rpm to 2010rpm ?
