Injector Cranking Time Calculation

[Badgaz]

Hi Everyone,

i'm trying to figure out how to calculate the optimal cranking time for my 850cc injectors. Since i've changed them i haven't adjusted the settings in my powerfc for the cranking time...which makes its not a quick start on cold start.

any help is appreciated.

cheers

What brand are the injectors? Need more details because they arent all the same

Start the tune from scratch I say. Injector lag times and voltage curves are usually completely different meaning most of the fuel map is probably out. You can't just change the injector size on the hand controller and away you go. You really need to set the injectors first imo, then tune.

Are you on ethanol?

All else fails, aerostart.

these are denso type I believe. I have the voltage lag times. I don't intend to run e85 yet.

Changing fouled plugs will get annoying quickly I would guess.

Ethanol wouldn't have that issue.

i haven't checked the new plugs yet to see if they are getting a clean burn....it does burble away after its been idling for a while....starts out ok though. i occasionaly run Gull force 10 which is 10 % ethanol 98 octane fuel.
