Oh... and one more rule, "Thin skin? Don't join in..." - This place can be as friendly as a pack of rabid, starving jackals...

Welcome to the mix.

I've noticed. Trying not to be a re-re.. it can be an uphill battle sometimes.

Thanks for the lukewarm welcome

Tuning is the same as it is at sea level. As Joe Perez often likes to point out. You need to stop thinking of in boost and out of boost, 15psi vs 10psi. You need to think in terms of kpa and a gradual scale like so.

http://www.boostedmiata.com/timing/aug-2008-fuel.jpg

Our atmosphere is at about 85kpa instead of 100 which would be sea level. Below is vaccume, above is positive pressure. But your fuel and timing maps are not concerned with that. They simply want enough fuel and spark for each cell of kpa vs rpm to give you the afr you want and not knock. Granted my idle and emissions cells are tuned for emissions but you don't actually drive in those cells anyway. Spend some time in the ecu and engine performance sections here. Read up on the tuning for MBT thread, and the various fuel and spark threads in the ecu forum. Look at the maps people made and why.

You don't really need to mess with fuel pressure if you go MS, just swap injectors and retune. I'd give you my map but my timing would be dangerous. But the PnP basemap is generally safe. I'll help tune if you want, when you're ready. It's generally better to get the ecu before the turbo so you're familiar with how to tune it, and it's safer.

I hate quoting power numbers, I can tell you Adam and me are roughly the same, at least in torque. I haven't been on any rollers, I tune on the street and track. I have no problem pulling evos, GTOs, and 370z's on the highway. FWIW my boost cutoff is right at 210kpa, my wastegate is just under. There are a few other turbo miatas, Sam Sharp, Poi, there's a kid in Rio Rancho with a white one, and there was Skyler from Los Lunas that was in the 10's. Fireindc is shivering up in Taos.

If you can't tell I really want some more fast miatas at the track so I have reason to push the envelope. Soren is taking too long with building the EP car.

Does Skyler still have his? That guy goes through projects like no tomorrow. Was his built? The name Poi sounds familiar, as does Sam. Can't put faces with the names.

Point taken on tuning in absolutes, I have little tuning experience, last time was messing with a u-tek on my wrx, which was ages ago. I recall a lot of that being throttle position, and a very low resolution map. MS seems awesome from what I've read. My buddy Jerry offered to build me a MS, he's made a few before.

How's the social aspect, I know Skyler is far from a social guy, anyone wanna meet up for lunch? Josh Coleman told me he was planning on getting together with Adam, and I was going to tag along for that.

That was years ago Skyler had his, but he sold most of the parts to a friend that still runs around town.

The miata has a binary tps which makes throttle position tuning pointless unless you swap a different sensor over. Jerry is a good guy.

No organized meets or anything aside from the local miata club, they drive around and eat.

I'm usually at the track. There is a track crew, but not really a turbo miata track crew yet. Adam needs to get new wheels and come out more. XD

I could only imagine the photos those two would come up with.

Adam DOES need new wheels. Or rather, more wheels.

Now that it's getting nice out, who wants to meet up one of these days?

Welcome to the forum man!

Thanks

Side note, also on the blog, I'm a re-re and put a few little dings in the front arches pulling/rolling fenders. Makes me sad since the car is/was so pristine.

Starting to make a shopping list for turbo stuff, I have a lot of reading to do. Buddy of mine has a MS daughterboard with my name on it.

Welcome! Great first post. Sounds like your off to a good start. You have a game plan, prior experience, a desire to learn, proper punctuation and grammatical usage. You even posted pics. I'm so turned on right now.

There is a wellspring of info on the turbo Miata subject, you should be able to find everything you need to get where you're going. There's some really in depth info as well. Along with some fairly large brain pans. Everybody here is willing to help someone who helps themselves. You will have no problem reaching your goals.

Hope you enjoy your stay.
