MS - Stock question
I am putting MS on my daily driver in prep for a turbo. If I wire the MS to the stock ECU harness, leaving the stock plug, can I just switch back and forth between the two ECUs until I get the MS tuned, or will that mess things up?
If I understand correctly, it should be fine so long as I only have one ECU plugged in at a time, and I'm using all the stock sensors. (All this is until I get the turbo on, of course. Once I do that there is no turning back)
I only have the one car, and if I need to go somewhere before my tuning is complete, it would be nice to be able to do that. If not, I'll have to borrow somebody else's car.

The other option, which would make the in-car portion of the wiring even simpler and cost only a small amount extra, would be to build yourself a plug-n-play harness as described by Braineack in This Thread.
