Maximum PW at cranking

Postby pnanassy on Mon Dec 21, 2009 7:06 am

Hi,

what is the maximum allowed fuel injection Pulse Width at cranking?
I tried to go over 32ms but looks like something in the software overflows and it displays some weird minus values.

Car starts only if i pump the throttle while cranking,this gives me about 40ms with the accel enrichment.

Car idles with 5-7 ms,2226cm3,5cyl,200cm3/min injectors

i2 datalog shows reasonable values (39-52ms),so its only the Motec ECU Manager software that has the problem?!

check "Post Start" option i think under fuel.
Also tune injection timing will help.
