RPM Peak of 65069rpm when cold starting
 

Im having a lot of problems starting the car at temps around 0 degrees celsius. I connected the laptop and sometimes it just turns over and the rpm stays at 0 rpm. And when the rpm goes up to 300-400 it wants to fire up and then dies and according to the log i had a RPM of 65069. After a lot of cranking it will start but it takes a lot of time.

When the car is warm no issues starting.. except sometimes at WOT it records a rpm of something around 7500rpm when i was at 4000rpm. It hesitates 1 time and after that it will continue without any problems. But that only happend like 3 times in like 2000km driving

Firmware issue or hardware problem?



MX-5 NB using the OEM sensors

Please post a data log of the problem and a copy of your MSQ.

Ive added the tune and the datalog when i tried to start and where the RPM peak is

Also added a datalog of driving where the datalog suddenly stops and just before it stops it sees a RPM of 0. This one is at high 7200rpm, but it also happens at other RPMs. I could find the datalog where the rpm jups from 4500 tot 7500rpm
