So after reading up on this
thread, it seems dwell settings also play a part in improving the cold start.
My dwell is currently set to:
Cranking - 8.0ms
Running - 3.5ms
Min Discharge period - 1.0ms
Some maps I've seen are set to 5.5, 4.4, 0.5 and also 8.0, 4.3 and 1.0 respectively.
Is my running time too low hence the poor catching of the engine?
Also has anyone pulled the code from the various OEM ECUs? Surely there is some pretty simple maths involved? i.e. dwell, IAT,CLT, injector firing type = cranking PW figure of....
(that's a hypothetical 11ms
My car sounds EXACTLY like this http://tim.kent.googlepages.com/2009...ning-start.m4a
It takes me 3 or 4 cranking sessions of around 2 seconds each before it finally catches since the recent temps have dropped so low. I even have that 'hydrolocking' sound which would make you think you're cranking too much fuel! That can't be so as the engine only starts to make that sound after excessive cranking attemps. I guess it could be due to the previous failed cranking sessions adding more and more unburnt fuel? I'm just clutching at straws though?
