How would the two tunes be different?

pointless. How about be easy on the go fast pedal and stay out of boost when cruising?

one is biased to high AFRS and high timing in cruise, the other not so much

same as 100kpa line, other starts adding fuel eariler

Depends on what you want and need.

I try to aim for 14.7:1 at 100kpa to around 3800rpm for my current cruising setup

also I'd be worried about transtional spark timing, say coming off of fuel load down where spark timing is at 35-40 degrees and mashing the pedal and jumping back up into high boost area where timing is limited by det


Like wise if you plan to use different fuels that could be a good reason to have mutiple maps, e85\93 LPG\93 etc

for some reason they dont sell e85 in that many gas stations around here, and theres a company about 20 min up the highway that makes it. but for the DD tune i want to run 89 and the race tune 93.

its a DD for the nice weather part of the year, so the tune i run on the street will be designed for lower power better milage. but i want to be able to go to a tune with the power also.
but you guys are the ms people, im just asking if its possible to do it. and being able to shift tunes on the fly would be nice, not necessary because i will have my laptop with me most of the time.

So, you're really going to go to the dyno twice to tune spark . . . once with 89 and a second time with 93? The cost of a second tuning session buys a bunch of premium . . . and you'll be happier with the snappier performance and better mileage to boot.

no i was looking for milage mostly. figured i can have power or milage not both. btw i grow up on old ford v8s so this whole 4cyl turbo thing is a adjustment.

just wondering if you can program it to have warnings/ do something about a problem. lets say a/f ratio drops below a set range. i would like a buzzer or something to go off. and maybe within the ms change settings automatically.

That rule mostly applies to carburetors where you have a main jet, a power valve, an idle mixture screw, and that's it. Imagine if a carb had twelve separate power valves, and you'll see why that rule doesn't hold true with EFI.

ok so once again looking through the options, and the diypnp is looking appealing, says its ms2 based. it uses the factory wiring harness too correct? any problems with the diypnp kit, limitations type things.

it has a limited number of inputs and outputs if you get too crazy with it. But a crap ton of guys here on running it.

you can't upgrade DIYPNP to MS3. but you could sell it and just buy an MS3 kit.
