Start of Injection Delay

Dang man.........sorry to hear that.

I am just trying to wrap my head around all these different maps and how they work with each other so maybe some day I will actually know what I am doing.

Way off topic but what would be the point of increasing the MFD map to over 100 at WOT?

What do these numbers actually represent?






Ohh boy........7 on 7.....that stuff will sneak up on you.......lots of stories started with that drink.

To me, it appears to be an easy way to indirectly increase the injector pulse width above and beyond what is commanded in the multiplier map. For instance, if your max MFD is 100 and it gets you a certain PW at a certain RPM/ICP, then increasing the MFD to 110 or higher will allow the PCM to calculate (using RPM/ICP) what the new, higher pulse width should be. It's a way to get the popping and stuttering that you hear in a lot of sled pulling videos too.

What do these numbers actually represent? The MFD map represents mg/stroke per injection event. It's a direct quantity.


Ohh boy........7 on 7.....that stuff will sneak up on you.......lots of stories started with that drink. You're telling me....I made 6 of them last night and drank them in about a half an hour. I slept good last night. I'd been awake for 31 hours since I couldn't sleep the night before.

Hope this info helps a bit.
