EJ, and crew:
here is a reply i got back from Danny, concerning questions i asked--
Does the stock ecu capable of sensing positive boost? Is the MAF being able to adequately support the boost?
The ECU doesn't have boost sensing capabilities. It just reads what is set in the ECU. It will not throw out a fault code like Hondas when boost kicks in. So in a way it CAN sense boost, but it it doesn't have boost maps or boost mapping.
Since the ecu reflash is still leaving in a small bit of the feedback loop, does that mean that the ECM is still able to alter itself?
The whole car runs off a feedback system at ALL time. So there is no way of gettting rid of complete feedback unless you run a stand alone system. The feedback is reduced and set for 12.5:1 a/f instead of the 10.5:1 a/f [which is stock]. The ECU will switch between 3 sets of timing maps to get the best a/f optimal peak running condition. This is why running higher octane will help, since most likely it will not run the primary map due to temperture and octane level.
One thing to notice is NOT all 91 or 93 (whatever octane it is) are the same. 91 from Arco or Shell is a LOWER octane than 91 from 76, Chevron, and Mobile. We found that on Tadashi's high compression corolla that 91 octane from Shell will ping and detonate w/ the same timing setup where as 91 from 76, chevron or mobile won't ping/detonate. Just something to keep in mind. Even thought people get 93-94 octane from out of state, the 'quality' of their gas might equal to our 91 or lower depending on the gas station/brand.

........very good then........the baseline is changed and the rate at which it corrects to that baseline is slowedHow long would the R&D need to last to get a program set up to do this?.......hypothetically, could it be done in a weekend?

Chebosto,
I have considered the ECU upgrade but want to wait until I have the exhaust mods I want installed (Crawford headers and High Flow Cats). If I sent in the ECU and had them program it as if I had those mods installed, but didn't as of yet, what would be the outcome? Would it be harmful, or make the system run a little rich and merely decrease performance a bit until I got the mods installed? I just do not wanna have to send in the ECU more times than needed.

update!!!
ATI procharger with PE injectors and my TT ecu program works GREAT! reports from a customer stated that it works perfectly and car runs super smooth... (i believe he dumped the FMU in lieu of the injectors and ecu mapping)
i am trying to get more details... but this is a user here on the forum.. that went to Ultimate Z tuning shop somewhere in the midwest...

more info on that Technos ECU, PE injectors and ATI SC..
taken from 350zmotoring:
"Cheston,
My car runs extremely well. For the most part, it runs as smoothly as it did when the car was stock. The car now pulls like crazy from 3k to redline. There is a slight problem with the idle. However, this started only after I installed my flywheel and new clutch. (I had to install the new clutch because the factory clutch would start to slip when the boost kicked in). BTW - This was not an issue when I ran with the FMU.
I can't begin to stress what a difference the TS ECU and PE 380 injectors made. It’s like the car came out of the factory with this supercharger built in. I can’t wait till TS gets a Z in there shop and tunes the ECU specifically for the Procharger.

The FMU is gone and so is the inline fuel pump. I hated that FMU. It felt like I was driving with a bomb under my hood.
Zed"
hopefully Zed will give me a dyno soon. but they have successfully avoided the use of the FMU....
