I know this is hard for you to wrap your boost addicted mind around, but just because it is built to handle it doesn't mean you should take it there.

18psi has a set up that he should be able to flog for a long long time w/o breaking. Over build for your target power level, and the result is usually increased reliability.

But I do like your style leatherhead...pull the pin on that hand grenade and let it rip!!

lol I sure hope so. That's what I was going for anyways





On another note, got bored tonight and since I can't tune (due to it raining cats and dogs and my car breaking traction OUT of boost)

I did this:








Wanted to go find a plastic sheet for this, started digging around my dads shop, and found a sheet of real carbon fiber from YEARS ago that I bought for one of my RSX's.
A little cardboard mockup, scissors/knife/pencil/marker and it came out decent looking IMO.


And of course I gotta rock the MT.NET sticker cuz dis is da gayest forumZ on da netterwebZ

Tuned a bit today and took it to the twisties for a few hours: CAR FEELS EFFIN AWESOME

Looks like I'm running quite a bit more boost than I thought, so you guys that keep telling me to turn it up will be happy LOL.




15.5 and creeping to 17 in 5th.
This log was started at 3100 and at a slight downhill slope so nevermind the fairly slow boost onset.


It seriously put a huge grin on my face today and was rock solid the 40 mile drive there, 10 mile drive through the twisties, and 40 mile drive back.
Still needs more fine tuning but nothing big or crazy. And I still haven't touched the timing map

It looks like I have a bit of what looks like boost sag. My source is at the manifold though and I'm running an mbc, so it can't be that.

Not really sure why its tapering after 6 like that. Am I exceeding the IM's flow capacity? That's the only thing I could think of

Being that JayL hit 20psi on the stock manifold, I doubt your IM is not getting pressurized enough.

You might have a boost leak that only shows under high pressure?

Where did you put your wategate signal source? I don't see it in the pics

Its tee'd into the brake booster line, which connects to the back of the manifold.

??? Shouldn't your wastegate signal line be BEFORE the throttle body??

I've heard that plumbing it after is usually done on track cars and can possibly mess up your WGA, but so far its worked like a champ and Ive had no problems.

Plus I really doubt THAT would be the reason for the boost sag, since its getting a signal from the manifold and not pre intercooler/piping.

Are you running a real turbo or Ebay special? Also might looking into what that air filter is capable of flowing.

Ummm you have a MAP sensor right? Is that referenced off the same line as your wastegate?

Are you at 25 psi yet because anything below that is safe faggetry.

ebay special 3076. I just can't imagine it running out of steam up at only 15.5psi when others are running smaller t28's to over 20psi.

Its really not a big deal. The car hauls *** and if anything I'll just add a little timing up there to compensate a bit.


Its just really puzzling and makes no sense.


*edit: bov and wga are on the same line. Map sensor and boost gauge are on their own seperate lines.

it could be a weak wastegate itself.

I'm starting to think that too.
Its a 7psi wga.

I have a 14psi one laying around. Guess I'll throw that in this week and see what happens.

That's your issue right there.

Love this car!

I might of missed it, but what made you make the switch from the Adaptronic to the MS?

Good question. Same here, must have missed it.

2 big reasons were:
1) user base and support
2) wanted to try something new

Adaptronic miata user base is tiny. The handful of people that discovered them with me here in the US, as well as [email protected] are pretty much the only people I could look to for support.
Then I switched to e85 and was completely alone (almost).

While being a pioneer and discovering things for other people is great, when you're stranded and can't get your car to start or its doing something weird and there are only a handful of other people that know the system none of which are online very often, it really gets annoying and irritating.

Another really cool thing about these pnp units is that they are COMPLETELY pnp. The adaptronic you had to splice into your wiring for the map sensor, as well as use a really stupid looking harness with an adapter board on it.

Also the amount of time it took me to set up and tune the MS is about 1/8th the time it took me to figure out the adaptronic and dial it in.


Overall, adaptronic is not bad at all, it works and its a good ecu. The DIYPNP is just a little easier to work with.

In my opinion.

Ok so I took out the 7psi wga and put in a 15psi wga. It started overboosting (even when I turned down the mbc) so I took out the mbc.

Here is a pull on the 15psi wga no mbc:



It STILL does it. Its not bad, and it doesn't really bother me, I would just like to find out whats causing the boost taper.
It goes from 14.6psi peak down to 11.3 at near redline.
