ms1 extra board 3.0 reset at startup

Post by fuscanet »

hi
im having this issue with cold starts
its a vw aircooled turbocharged 1.6 engine.
after starting it runs very good.
can any expert look at my log and see if may be due to low voltage or what?
its driving me crazy

other strange problem is that few days ago my fast idle valve just stop working, i decided to test conectors, and has 12v, so I checked the valve, if i plug directly to a 12v source it works fine but not attached to the ms.
the conectors do contact the valve perfectly, its like there is not enough amps in that feed.
this is really strange, any idea??

i accepts all types of recomendations
attached log and msq.

I'm not seeing any resets. Mostly, you probably need to adjust the cranking pulse width.

Try testing the fast idle output on a Stim.

Mat thanks for responding.
Do you think my pulse is too high ?

If giving it more throttle when cranking helps it start, the pulse width is too high. If that makes it worse, it's too low.
