mad_pete Posted June 25, 2017 Share Posted June 25, 2017 In getting my raspberry pi contected it had problems connecting, I'm getting occasional flash read errors but maybe unrelated but the engine is now cutting out at 1500 to 2000. Is it possible I've pushed some bad settings or wrong firmware map? Or any other suggestions gratefully received I'm 50 miles from home at the moment.

Quagmire Posted June 26, 2017 Share Posted June 26, 2017 Cutting out as in : Dropping stone dead, and you cannot get above that rev range or as in it is missing heavily but is ok once you get above 2000rpm? If the first i would check silly things like rev limiters, overrun fuel cut etc to make sure that you haven't accidentally set some funny trigger conditions on them. If the second I would check soft rev-limit settings, check your spark and fuel tables still look reasonable. Check your air, coolant and map sensors are giving decent values too.

mad_pete Posted June 26, 2017 Author Share Posted June 26, 2017 It's the second. Runs like a loose connection at those revs. Rev and drop rev and drop stuttering. Apply more throttle and it was happier at the higher ranges and drinking lots of fuel. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 26, 2017 Share Posted June 26, 2017 Bit more info would be handy - flash read errors from what? If you've pushed glitched data into the MS you should be able to pull it out with Megatune & see what's what, compare to a known good settings file from before you broke it Quote Link to comment Share on other sites More sharing options...
Quagmire Posted June 26, 2017 Share Posted June 26, 2017 does it idle ok? Quote Link to comment Share on other sites More sharing options...
mad_pete Posted June 27, 2017 Author Share Posted June 27, 2017 Tuner studio gives a flash read error and it does idle ok. Quote Link to comment Share on other sites More sharing options...
mad_pete Posted June 27, 2017 Author Share Posted June 27, 2017 Fired up the laptop, straight away rogue fuel map cell flagged up 2000 rpm 80 mpa should be 50, was 142. That may explain rich running and increase in fuel consumption... i put put it back see how it goes later. Quote Link to comment Share on other sites More sharing options...
mad_pete Posted June 27, 2017 Author Share Posted June 27, 2017 Seems happier now. Will massive overfueling upset the plugs or exhaust sensor ? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 27, 2017 Share Posted June 27, 2017 It can, but likely be OK if it was just a short stint. Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted June 27, 2017 Share Posted June 27, 2017 Well it might foul both of them, a bit of normal running should clear it though. Quote Link to comment Share on other sites More sharing options...
mad_pete Posted June 27, 2017 Author Share Posted June 27, 2017 It was running like this probably about 4 hours to Beaulieu round the course twice and back again. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 27, 2017 Share Posted June 27, 2017 I wouldn't worry, a good motorway stint should sort thing out... If it isn't missing, then the plugs are fine. Quote Link to comment Share on other sites More sharing options...
