Although I welcome AEM's involvment, I have little faith that anyone will bring something to market soon. Sounds like Sound Performance is working on something, but given the number of false alarms in regards to an AEM EMS, I will temper my excitement, until I see a few test units running on cars.

There is no reason to have a stand-alone controlling the engine at idle, cruise, and part throttle, as it adds tuning complexity, hassle, and time to the process....given that the stock ECU works nicely under these situations.

this might be a different kind of aem product.

The VQ35 is unique, becuase we have a CAN bus network, so reomving the ECU is not feasible. Same concept as the HKS FCON...the stock ECU remains.
Last time I spoke to a rep from AEM at a trade show, he said they dookie canned the fuel rails due to the fact they were not visible on our cars
so much for form following function..He also stated the EMS was "in the works"...This was of course 1.5 years ago
And we have heard little since.I would not put my faith in a prduct that is vapor ware at this time..This reminds me of the ol' DREAMWORKS incident..

With the current EMS options on the market, I dont see a whole lot lacking from the current offerings.

Then when FI comes, you will just need to add a MAP sensor, and retune.

my car the PE TT on 8.4psi and through a tiny 2.25" Injen exhaust got 428whp and 463wtq but the tune was not completley finished. i think it still may have had some power left in it but we were in a hurry to get the other car done. were putting a 3" exhaust on soon and raising the boost some more so we will have better numbers then. as for the ati procharged z it made 381whp and 336wtq on 9lb pullies.

I'll come back down there and I can tune it some more with the 3 inch exhaust, and the heavier boost actuator spring.

I don't see why you would make more more peak hp with a larger exhaust. The turbo will spool faster, and reach peak boost at a lower RPM but unless you increase the boost your peak hp will stay the same.
