that's cool, have you had any luck with closed loop? I never could get it working. open loop works real well though.
a tps is really only useful if you have a tiny turbo you don't want boosting all the time.

i'll have specifics later, with pretty charts and all, after I get home. I will go ahead and tell you we broke 250 rwhp on the dynapack on a rich tune @ 14 psi

227.1 wtq / 255.4whp were the final numbers with a spike to 15psi at about 4000 followed by a pretty even 14psi to redline.
Here's the chart showing what we could do with the MBC (dotted lines) versus the MSPNP's EBC.
How's it feel Ben? Felt good to me

RC 440s. I'll have datalogs later...
Didn't get a chance to open her up on the way home. Bumper to bumper the WHOLE trip. I did make the BOV scream for the ladies under a large bridge though. Low speed cruising and stop n go, the MS did great.
Gonna go for a ride after waiting another 30 minutes for traffic to die down.
BTW, the dyno operator Scott took the car for a ride and came back grinning like a chesire cat.

Just looked this over, and the datalogs are reporting 72% but that's not right. The REQ_FUEL we used is off a bit from what it should have been which won't hurt anything, but will make the DC reading inaccurate unfortunately. Doing the math though these injectors are maxed out for sure... IMO I'd go with 550's to put this kind of power down with stock fuel pressure and keep the DC's in a good spot.
The REQ_FUEL is off due to an oversight... we tweaked it earlier this week as a quick fix to get the car driveable before tuning, and should have set it back today before tuning to be honest... not a big deal but it does effect the DC readings in the datalog. I have to take the blame here... I honestly thought the map we started with this morning was the base map I setup for 440's from BEFORE we tweaked the REQ_FUEL as a quick fix, and I should have double checked it...

Can you post correct injector settings for RC 440s? I might be installing mine this weekend (2000 motor).

The MS does a great job on the power runs. Unfortunately everywhere I went yesterday evening I got stuck in awful traffic and/or behind old ladies. Coupled with the fact that the car is so fast now, I run out of room quickly. Maybe tomorrow I can get a long full WOT pull in.
That's too bad about the IJDC. I have to take blame there, too. Afterall, I was the guy who made the car run on 440s by moving req fuel until it idled well
It would have been nice to know real world duty cycle. Before I used those injectors I calculated 85% max dc @ 250 horse. We did hit a little more than 250 and we are running a tad richer than I calculated for though, so maybe it's upwards of 90%.
Brian, 2.5" tony dp transitioning to 2.25". I'd be sure that your car has a better FMIC design and larger exhaust. 6" rear. Still haven't had a good WOT run, but so far the car pulls hard but the gears are short. I actually just got an offer on my 7" hybrided miata/rx7 LSD swap, but me thinks at this point it would be smarter to keep it. On the dyno we did a wastegate basline run before setting the EBC, wg 6 psi did just shy of 170 rwhp. As a marker, 3k miles ago with the bandaids I hit 165 rwhp on 7 psi on the dynojet in a COLD room.

Probably the same old story with the greddy wastegate....needs a helper spring.
yeah ben, we need answers!!!! got a datalog of the last few dyno pulls...I'd like to look over them in MLV.
