Default Just pulled our '91T off the dyno...

Here's the specs...

BEGI Series 3 Turbo'd 91 Miata
MegaSquirtPNP MM9093 EMS w/ EBC solenoid
Stock Internal 1.6l, GT2560, BEGI FMIC #2
Walbro190 FP, 460cc injectors, 3" Exhaust
225 wtq / 246.4 whp at 13.7psi (on pump 93 fuel)








It runs out beautifully... I've just got a few cosmetic things to do on this car and it will be ready for PRI next month. It's a beast though, time to go take a drive

Thats Great news Jerry.

Just curious though, anyone know the size difference between the 2560R and a 15G? I remember reading that they are a bit bigger than 15g's

Just shoot me an email-- I'm basically doing commercial tuning 1 day a week right now, usually Thursdays. Can't do much more than that and keep the rest of the business rolling .

Same here - need to get the EBC working... and hook up the oil cooler. Then I want some dyno tuning.

I really don't understand why you guys aren't in on the megasquirt action yet? It does everything you want it to and more. Plus it's really not that hard to tune. It would definitely go well with your S kits. Considering a PNP parallel solution can be had for sub $500 for the '99+ owners 90-97 is even cheaper.
Then the MSPNP makes going MS a cakewalk. Couldn't get much easier.

Does ebc hold the wastegate closed longer until its absolutely necessary? Im trying to figure out why the boost curve is so much smoother with ebc.

The wastegate holds the wastegate closed until your reach your desired psi. It will then open and regulate boost so you can tune EBC to hold boost flat to redline, or drop to redline a tiny bit if you like it better that way. Holding the wastegate closed instead of letting it open as you build boost makes the turbo spool faster.

It produces a pretty big difference in power at certain points in the graph.

The EBC doesn't produce any power the turbo does. You tune the EBC so you run the max boost you can throughout the powerband to produce the most power under your knock threshhold.

I'm so full of **** it isn't funny.
