Megasquirt

[Redtruck-VA]

When using sequential fuel injection, the timing of the end of the squirt (talking about our trucks here) is important for efficiency of delivery. Obviously this point changes with a aftermarket cam. Since I haven't heard anyone mention "fuel timing" before makes me wonder if the tuners are making any adjustments here or not.

Update, ran out of patience with trying to get the MS3 to idle right. Pulled the MS3-pro, rebuilt the wiring harness and re-installed the "High Idle" mod. Running good, idling a little higher than before, but is solid. Just for information, the old girl would not idle without the "High Idle" mod installed. Still got some things to sort a little but feels good having my truck running solid again without a dash full of light. The next decent day I'll re-install the PSC1 and the truck will be completely back to normal.

Here is a picture of the harness I put together.
Has the C106 connector and 06 COP plugs.
