Ah HA! Found my lost boost!

History: When I first wired my solenoid I put the diode on the wires about 2" off the valve. Then I proceeded to wrap it in electrical tape as if I was trying to suffocate it. I was also smart used two black wires off the valve so I later, if I ever need to, I could not determine which is which.
Flash Forward: In my haste to get my car running I seem to have connected my solenoid backwards so the wrong end of the diode saw the 12v source. Over the past few day of finally driving the new car I've had a supercharger like boost as I'm only at wastegate. EBC was not operable. So pulled the wiring apart to see that the diode on the wiring was fried. Fixed. Still nothing. So I open the MS and find part of the circuit fried. Fixed. Now I say I found my lost boost. Much Improved. (I'll post pics of the board later, need to download off camera). Still missing about 500RPM of spool, but better than before....traction is a thing of the past again.

yeah i know, cells we untuned. 11.0:1 is rich too, i dont wait for no 160*F.
aiight here's the trace that blow out...glad i saw it, i was scratching my head on this one for a few minutes because i had no connectivity between the AIC hole and the DB37.

because i never hit those cells before, that was my first log since getting the EBC working. like I got it working, pulled out of my parking spot, logged it, and parked the car and posted.
notice the other log overlayed? When warmup is not on, that **** was perfectly flat at 12:1 - 11.8:1

I only see RPM/MAP/Boost(psi) in the first box, but I see 4 lines.
I'm also wondering why MAP and Boost are different lines... don't both of those read off the internal MAP sensor?

Looks like his MAT at 12 psi is 86* and at 8 psi its 75*. You guys are reading the max MAT temp he saw over the entire datalog. That is probably when he was at idle and the sensor heat soaked.

sMy AIT sensor reads dead on based off an external thermometer, if the sensor is reading high inside the pipes at idle and I remove it from the bung and blow on it so it can read ambient temps, it's dead on within seconds.
Ok, I believe my issue with my lost spool was because I always forget that my pedal should go to to floor. Did some ninja tuning on the way to work:
Glad to hear this Scott, I bet it's a good feeling to have boost, even if it's again, I should be so lucky to feel so for myself soon.
Scott builds two turbo Miatas, me not even one yet. :(

D'oh!
Hey- Atlanta, Arlington, Chicago, Phoenix, they're all in that weird part of the country east of I-15 where you can't get good fish tacos.
And the comment about the MAT being "a bit high" was a joke. After a long boosted pull I routinely see 90-100°F even on cold days. Here's one from yesterday morning. If I recall correctly, this was up a slight hill:

Excuse you, good sir, as I believe you may have misspoken. It is my firm belief that Athens, GA (just outside of Atlanta) indeed has some of the best fish tacos in the country, if not the world.
But perhaps we speak about different things?
