just wanting to no if my jdm 13b-t ecu will run in the states. it will be a s5 ecu and from in the past i have heard that jdm ecu's will not run very well because of all the elevation change to different octanes of fuel please help with this its driving me nuts.

 

so try it out. put in a couple cans of octane booster, borrow a wideband, and rent some dyno time.

 

Yes the JDM Ecu will work. The JDM harness will not because it is not long enough so you have to extend them which is a royal pain.

The one problem that seems to afflict many of the ecu's from Japan is they will often not run the rear rotor (front rotor only). You can try it though.

 

No, the jdm ecu WILL not work unless it's chipped. There's lots of threads about this... You could use the search button. But yeah, you gotta rechip the N374 to work and no have the rear rotor fuel cut.

 

^ agreed.

 

wow it's really not plug n play?? screw that jus go stand alone (might as well!)

 

I had a 89 T2 (real deal) and it ran perfectly fine with a regular n374. needed something for use while the n370 was getting chipped.

 

what abt the n318 ecu?

 

Maybe the N374 ecu you used, was already chipped.

Amv, it if plug and play. But the settings are different. There are people here who have used N374 ecu's and it has worked. But the other 80ish% of the people who have tired has failed. (Me including)

 

There is no N318 ECU.

And back to the subject, I've also read plenty of threads where people swear off the N374, but there are also a handful that get it to work.

 

the wiring harness is not an issue one bit being my car is rhd but im just wondering cuz when a buddy of mine got his r33 over here it wouldnt run for **** cuz of the octane difference they have over in japan. and y wont an n370 work its the same motor same everything except for one is set up for the states and the other is for over seas right?

 

if you car is rhd, use n374 if its lhd use n370

 

hey russianmob are you wanting that motor of mine its not a bad deal 2000 obo and i would b willing to deliver it to u
