i have noticed that a lot of ppl on here experience fuel cut...some around 4500, some around 6...it has varied, but i've wondered exactly how many JDM 7M's ARE out there...i've hit a high of 16psi from launch to about 110 and from the way i've heard people describe fuel cut, its like an "invisible wall"...which i've def. never experienced that...so i guess if any of you have it fuel cut, what psi? hell, even for the USDM 7Ms, reply back. this is just a topic i'm not too familiar with and just want to become more EDUMACATED!:icon_mull

If you're not hitting f/c at 16psi...

A.)You're boost gauge is off
B.)You have a Fuel Cut Defenser hidden some where
C.)You magically have a group A MAF system
D.)Standalone system
E.) A BOOOOOOSSSSSSSSTTTTTTTT LEAK

well....boost gauge has seemed to work fine...meaning spool time and all...a Fuel Cut Defenser...possibly. well when Floyd looked at my car the first night he saw it, he said that one of the fine little "gadgets" running along the engine bay was something that removed the restriction of boost...i honestly cant remember word for word, but he said that it allowed more boost...hmm.
what do you mean by a:"A MAF system". and then standalone...pretty sure i dont have that:( ...and for boost leaks, i took care of that problem when i first got the car. Unfortunately, for rod knock, its been a LOOONNG time since i've went past 3rpms because its my DD and well...i want it to last as long as possible before getting it fixed...last time i boosted, it was only to like 11psi(still had some throttle left). I dunno. it's not the biggest of my worries right now...just somethin that pondered my mind.

wouldn't the jdm fuel cut be the same as the usdm fuel cut when both motors are stock?

well i dont know how much of a difference it makes internally...but i believe the UDSM is 220 or somewhere around there...and the JDM is what, 247? somethin like that...i know there is a hp difference...and i was curious as to WHERE that hp difference came from...and i didn't know if it had anything to do w/ fuel system..which is why i've made this post!:)

where does it say that they have hp differences... I've never heard that... I was under the impression that there was no difference between the jdm motors and the usdm motors other than the egr systems...

If you remove a worn out, BGH, rod knocking USDM engine from your car, and install a JDM 7mgte, SAME ELECTRONICS, unless you did something else to the engine, or left something off to provide a fault in the induction system, you will have the same result you begin with. Now if you use a JDM ECU, or other non USDM/non stock electronics on your car yes you will have something different, but if all you change is the longblock, you are having halucinations. the JDM engines are a little different, no EGR, they come with block off plates, other than the 4 above mentioned items, previous post, the result will be the same as before unless you had a really worn out engine, turbo or both.

thats what I thought... but I didn't know that the jdm ecu's were any different either... I thought that they were the same unless you got a turbo A...

heh, JDM 7M's are identical in horsepower and torque to the USDM models, regardless of whether or not you use the stock ECU to your car, or the JDM ecu. it's all the same. anything else you've heard is just plain wrong, or from someone who's obsessed with JdM tYtEneSs, yo.

your JDM motor is identical to every other USDM motor, save for the EGR setup. there is no hidden horsepower in the JDM's. and you wont gain any power by adding a stock JDM ECU, either. those are myths.
