Need some help with cold start, not rpm syncing and the composite logger does not look like how it supposed to look i think.

Im using the stock 99-00 sensors with a MS3x, and this problems only happens when its cold outside. Today i couldnt even get it to start. Im drove the car for a few months now with not much problem except the cold start issues.

Is my cam signal bad? or something else? The MS3x was build for a 94-97 1.8. but i rewired everything to work on a 99-00. But i believe the cam an crank signal are the same kind of sensors. And it worked for about 8 months now

 

Huh, cam should be 2-1-2-1-2etc, not 3-3-3-3.

that aside what're your cold advance and crank advance settings?

 

Crank advance is 10 degrees like it was and cold advace is 1.2 degree offset at 0 degree celsius

The MSQ is also in the first post

 

Could it be noise in the signal that it detects something that isnt there. Maybe the cam wheel spoke or something

Tommorow im going to check with an older firmware to see if that works i dont no anymore

also changed the cam wheel from my other mx5 and and the one in the ms car in the other one. And that one started right up. So the cam sensor itself is good

 

So i got the car to start with an other car jumping. Startmotor was good strong but the voltage dropped to about 9v without jumping with other car. Without i also got a config error telling me the battery voltage was to low. So i think something is drawing a lot of power during cranking, and the only thing possible is the starter motor

Its a 2 months old battery and i had a lot of cranking yesterday and still going strong except for the low battery during cranking

I also had a datalog with 65067rpm and about 240kpa and a -17 clt when it was -1 outside when cranking. And a few MARK (number) RESET
