Congrats on the amazing numbers! That thing must be a beast to drive and I can't wait to see what numbers she'll put down at the track. This really makes me excited about my engine build and upgrading to the green over the winter. I need to fly you out to BR to tune my car ha!
Great job and again VERY impressive!!

In regards to the above quoute I am curious as to what 2 byte load you are seeing at 37psi? I was under the impression (never been able to peg it myself) that the ECU would clip at 379.85 for load. This might have been be a load calc function (came from Smogrunner and I dont recall the specifics).
Secondly, is this with the stock MAF as well?
Lastly, what ignition are you using to fire this off.
If you want to answer via PM's please do but I am really curious as far as the ECU aspect.

First off congratulations for some phenomonal output from the Green and a stock ECU.

Scott, I didnt personally hit the clip I listed (379) but I have exceeded 319 several times with no issues. My ignition felt like it was breaking up (30+psi above 6000) but thats not the brick wall of fuel or boost cut as I understand what you are saying.
edit-I also have my boost cut timer set at whatever the max is 16375000 msec or whatever.

Tony congrats on an awesome car. I can't wait to see the new times. is thunder still open right now. Tom if you keep doing what you do with the stock ecu you know you might have to see what you can do with mine when I get my 20lt lol. good luck and keep on tuning. You guys are making me consider the water/meth injection more seriously.

Hey oneguy, long time no talk to. What's this TX I see in location? I assume you're still in Florida? How's life treating you? Are you still 'upgrading' the Evo? Tony and I have been having a little fun since we saw you last. I just got back from Ohio last night. Spent a few days on the dyno and watching Daniel Buschur swap cams. Sunday I went to the drags and watched David run his 9.65 at 151+. The starter kept commenting about how he thought that it was supposed to be a street car. Obviously, the comforts of a street car with the performance of a race-only. Good to know you're still out there. I'll be coming down your way sometime this winter. I think OKIX wants to get in a few runs before spring.
I try to always leave Texas up there since I have been moving a lot and I have only been in one place longer than two years other than TX. they have me scheduled to graduate Feb. 22 so I'll probably know a week before that where I am going next (Jacksonville, Norfolk, Corpus Christi, San Diego, Hawaii, Guam, or Japan). I'm hoping for Norfolk or Corpus. Where in FL is Tony planning on going?

We've been looking at Bradenton, since one of my best friends has a new home just 9 miles from the track, same highway. Free beats Hampton Inn every time. Not sure yet though. Congrats on the last payment, now you start payments on the new dishes, furniture, diapers, diapers, ...

If you weren't logging two-byte load, if you tell me your intake temps and baro reading at the MAF, I could give a rough estimate. If you weren't logging those two, then just tell me the air temperature that day and I can give a rough estimate.
I created a boost estimate equation in a thread in the ECUFlash forum and I want to see how accurate it is. FWIW, the equation is:
BoostEst=[(load*T)/(P*VE*280)]-14.7
T = actual intake air temp (not MAF temp) in degrees Rankin (degrees F +460)
P = atmospheric pressure in psi at the MAF(baro)
VE = VE of engine at the RPM being measured
Quick example...say that when you were in Ohio and the temps inside the dyno room were 50F, resulting in a intake temp of 60F at the intake manifold. I will assume 100% VE at the RPM measured and a baro drop to 14.5 (probably more actually) and your stated boost of 37 psi:
37 = [(load*520)/(14.5*1*280)]-14.7
load = 404
If the dyno room was warmer, say 70 and your final intake temp was higher, say 100, it would change load to:
37 = [(load*560)/(14.5*1*280)]-14.7
load = 374
Higher temps would decrease the load even more. Anyway, I'm curious too about your data.
Eric
