But that isn't a Megasquirt thing, it's an ECU in general thing.

How can you expect a dumb device to 'know' the size of your injectors unless you tell it?

so any suggestions on where to read up on helping me with this start up?

as Sav said, I probably have to alter the VE tables or retune the coldstart.

time to start searching through the MS section for answers.

thanks for all the help.

Change the Req_fuel number to account for your bigger injectors, as you have MSII everything else will scale more or less.

It's all in the manual. http://www.msextra.com/doc/index.html

The link I posted is more appropriate, the megamanual is B&G code based, the MSExtra URL is for the Extra code bases which we all use.

First, get a mcdonalds straw and sip up all of the unburnt fuel in the cylinders; then get on your knees and praise god you didn't hydrolock :P

Then set up your ECU as mentioned above

Req_Fuel needs to be decreased. Formula (approximately) is New Reqfuel = Old ReqFuel * (old injectorsize / new injectorsize).

Cranking PW also need to be trimmed by the same ratio.

(Does MS2 specify cranking PW in absolute times like MS1? I can't remember.)

EDIT: No, it does not. It's in %, so you can probably leave cranking PW alone.

Might need to trim priming PW, though.
