But, because you have more complete control of the fuel using this strategy, it should be more insensitive to the flash revision than the GReddy way - barring some kind of bizzare changes in the flash revs.

^ a little too early for that assesment, I'd say. We haven't even verified the changes he made yet.
KJ238, I want to verify the units that you are using for pressure. Psi or bar?

(BTW, I posted acceleration numbers gained with navigational-grade accelerometers when I first got the car that indicated it did (or does) infact do 238HP.)

I'm curious how you managed to conclude that.

Lol sorry... i live in a different time zone remember.. Plus i had meetings till late last nite.. sorry people... just got to work...
Ok the problem was with the incorrect location of the GReddy pressure sensor... I was really ticked off by all my problems being caused by a little thing like that... I'll explain more later..
Boss is on my tail

I am not very car inclined although I am learning more everyday. I think that since day 1 that i bought this car till now I have learned a shitloads about my car. Anyways, how i have been tuning is by reading my boost guage and adding/subtracting fuel according to Air Fuel.
The thing is I neva really used the log. So when i did use the RTD I found the the pressure was constantly at -1. When the boost meter showed -0.2 it was ard +10 in the RTD. THe higher ranges were okay though... This led me to believe the sensor was acting differently from what i thought..... But after researching and checking everything further, i found my problem.
The installer did not remove the VFAD. I read about it on other posts and decided to remove it myself.. Then while rereading the GReddy Turbo Installation Instructions i discovered that the pressure sensor was supposed to be attached to where the VFAD was supposed to be..
It is not entirely the installers fault as the instructions were in Japanese and he just did it by experience. Since then i have rechecked everything... and it is fine...
Just bugs the hell outta me that all my problems was caused simply by the hose being plugged to the wrong location.
Although i have to admit trying to find this problem has helped me understand my car a hell lot more and about how it works... Thanks everyone for all the help they've offered especially MM and MadDog..
Since the e-manage has been adding fuel when i am not underboost, my PCM has been subtracting.. How do i get my PCM to unlearn this and reset... Will reset the KAM and NVRAM do it? or do i have to unplug the battery and leave it overnight?
Now to get my Ignition timing running? MM==> Do u think that the pressure sensor could have made the ignition thingy disfunction?
Really happy to get rid of this problem...

Wow. Quite a story. Where was the pressure sensor reading from?
First, I would set all the air flow adjustments that you did back to zero.
I can't remember about the KAM and NVRAM. Unplugging the battery and stepping on the breaks to drain any caps will reset the memory just fine. You don't have to wait overnight.
Sounds like you are back in business!

New Install Manual
Does anyone agree with me that it is time for someone, Greddy?, to re-due the Turbo install manual? Personally I think it is pathetic 
that the end user community has to be the ones to figure out how this kit really needs to be installed, and modified to work properly.
If it was not for die hards like
Jeff and Tim and others endlessly going through the trial and error process and figuring this stuff out, we'd all be up a creek with crappy running Turbo's.
Jeff or Tim, or Both, with all your accumulated knowledge and know how with this car and Turbo Kit, I have one request that I and I am sure others here now and in the future would be willing to pay for.... maybe even sell it on Mohdparts.com web site for $75 or something..... a rewritten or supplemental Install manual, complete with detailed photos of everything People are f'ing up on install - hose connections, BOV adjustment tips, Boost controller install info (Profec e-01), harness mods, etc.... and maybe even some real advice and screen shots of tuning tips, etc.... now that would be worth paying for!!!! Maybe even Greddy would buy the rights to it!
Jeff or Tim with your skills with the computers (Nice website by the way) putting together a small .pdf manual with detailed photo's (hoses end to end) along with quality photo's of where exactly modifications are made should be a piece of cake.... The reason I suggest this is that some of us, I hope I am not the only one, read what you post, but do not have enough knowledge/confidence or experience to put the info into use because we are not 100% sure exactly where to drill that hole, or cut that wire. They say Pictures are worth a 1000 words! especially when your not 100% sure what your doing.... I don't know about anyone else, but being 75% sure
with a 45K car is a little scary for me!
I hope you take my suggestion and make a kick butt supplemental install manual....
I will keep my fingers crossed!!!

Yup i've set all air flow back to 0... I reset the KAM and NVRAM.. Was gonna pull out the battery and step on brakes last night, but i didnt have the proper size tool to open the bolt.. Will do it later...
Yes I am back in business... woot

I wouldnt mind rewriting the manual with some help from MM and Maddog for the pictures... The stock install manual isnt too badly written and the pictures aren't too bad.. Just that they left some details out.. And we can insert all the 3 fixes into the manual...

Nice... I think you're the only one besides me and Jeff that has cut the P2's loose so far.
I'm going to set up the timing controls this week and head to the dyno again (assuming I get the timing working properly). This time, I'll be pushing 10psi and only dropping to 8psi at redline.

Hey guys been busy just started reading forum again. Question, if I were to hookup my WG
to the turbo side like you guys have said, How would I still control boost thru my E0-1.
Since the E0-1 control valve is attached to the com. side to the intake manifold and the NO.
is connected to the WG. Please explain, maybe I'am alittle slow today..

I set myne up with the boost controller com port to the actuator. Boost controller NO port to the fitting installed in the compressor outlet. The intake manifold port gets plugged. The boost controller pressure source also needs to be connected to the fitting at the turbo outlet. Boost gauge and EMS pressure sensor to Throttle body pressure source.
