Another MS conversion, Progress, at last. Options

[JimN73]

I've been talking to McMark for some time about the MS/ignition upgrade. I decided to to take the plunge a few weeks ago and asked Mark to put it on his schedule.

Jeff (JSConst) had bought a kit from Mark and decided not to use it, so I bought it from him. All of the pieces are together and Mark has time starting on Sunday.

Unfortunately, my time is limited so I may not participate much. I will add updates as I learn of them, or Mark may do that if he has the time.

I tried MAP only. I tried TPS only. I tried blended. I tried adding a reduced orifice to the MAP hose. I tried increasing the MAP sensor lag/smoothing. I tried more fuel. I tried less fuel. I tried more timing. I tried less timing. I looked at datalogs to see if it was a noise issue in the wiring.

Nothing made it go away.

I did some research last night and I will be working on an optional MAF solution for my kits, but I'll be finding a MAF that it sized more appropriately and go through the process of mapping my setup on a flow bench.

Mark do what I did hook up the MAF to a spare channel and plot the curve and compare it too the MAP and TPS and see how smother MAF is while under load.
