So what makes the JDM ECU un-usable in our cars?

$1300 for full ECU. In other words retaining stock ecu unaltered and being send a complete drop in ECU. Some folks might want to keep their stock box on hand for dealer visits. Though if the gain is minimal, it might not be necessary.

I will be getting a Stand Alone and be reporting back. I will also make Base maps that I will share with the Message board. and Do before and after dyno runs on the same dyno with my owen car to show the inprovments.

i believe all cars now from overseas are serverely detuned to meet ULEV and LEV standards. the ignition maps is where we will see our big increase in power and fuel maps will help a little but not as much. combining some more free flowing mods will lead to more HP and TQ gains also. the advanced timing will also help the bottom end more. this will probably be advised for NA only cars period though. so if SC or TC is a possibility i would stay far away from it.

WRBLUEWAGON - keep me posted on the stand alone. We all know that MAFs are the worst thing when trying to tune a car for performance. I would love to delete it from the system. And since I aim to be squeezing soon, I want to maximize the injector duty cycle to it's fullest potential.
2k3silver350z - I think (hope) we will be pleasently surprized by the gains of our ECU's. Foriegn companies really crap out american programs in fear of our emissions laws. Having had an S4 prior to this, I know that a euro spec ECU was significantly faster than American. Not as night and day as stock to aftermarket, but a noticable difference which was not achieved through raising of boost levels. The Euro and Amer both ran 8 - 10 psi stock. Gains where achieved with timing advancement, A/F mixture, injector duty cycle, etc. So we'll see.

Well as fare as Ing. Duty I would suggest to stay under 85% on street gas street tune. and try shooting for a 10.8 A/f on street gas at least 93 oct. I have had my owen Rex go nuts a 11.2 on 94 and I had knock around 5500rpm. I would do injectors and pump when adding a blower. Even at safe A/Fs the injectors could fail if open past 89 to 90% on street trim and then BOOM. I think PE is working on a solution. Do you know what the factoy inj. are rated at I could give a round number of power the stock fuel system can support. You can also push Ing. flow with a nice big pump like the HKS units. They flow about 310lph and I pet our stock denso unit flows about 130.. Don't even think of adding boost until that is upgreaded. The supra unit would be another option about 255lph. And this is based on the way nissan set up the electical drive on the factory witch could need to be upgreaded as well. Lot of work to really do it right.
