Mah tunez, look at thems.

So before I begin, let me say I have no experience tuning a car, let alone a turbocharged car, and I have no experience with MS.

I compiled this tune through some other people's maps, I want to make sure it looks ok:

Any help is appreciated :)

why do you go so rich so early? I still target 14.0:1 at 105kPa. You do like to cruise and enjoy better MPG right?

105kPa is ~ 15psi, so right around ambient pressure, so I doubt anyone would be cruising at 105kPa, since that would be WOT with no vac and no boost yet.

depends how big your turbo is.

if you have a tiny tim turbo that spools at 2 grand, you could cruise at 0psi (i did with my nissan 240 with KA-t on a t25)

and if you have a larger turbo, you can pull quite a bit of vaccum at cruise still.

15psia yes. Watch your boost gauge while you cruise on the highway, you'll easily pull a pound or two going uphill or passing traffic, but there's no reason whatsoever to start dumping in so much fuel between 80-100kPa; that's the range I typically hit on the highway.

Like I said, no experience with turbo cars :)

Thanks.

I understand riders AFR, better safe than sorry. I compiled a database of all teh tables on here i could find from people that have alot of posts ( hopfully to get decent numbers ) and i found that the transition stages etc were so different tis hard to know what to do. Would up a long hill at 100kpa @ 14.0/1 be a scary bad thing? would be great if something like this could be added to the faq. just a table of a recomended started a/f ratio. Even looking at different EMS basemaps there all over the show.
