Greddy Emanage
 

Spoke with my tuner today , I mentioned buying the Greddy Emanage piggy back, and he tolld me its not worth it , mentioned some issues with the way piggy backs actually work , and to just buy a stand allone AEM for tuning . So I think I'l save up and pick up a AEM .

You mentioned pulling your trac fuse to remove your speed cut. That should not work on a JDM afaik.

Agreed.

Speed limiter
 

I read that the trac fuse will eliminate the speed limiter and traction controll if removed on Japanese speced Supras.

Where did you read that?

Trac fuse
 

Pulled my Trac fuse , and it does eliminate the traction control and 180kmh speed govenor , on my Japanese spec 94 TT Supra.

Is it limited with the fuse in? You might just already have speed delimiter piggyback device installed by your ECU.

Yes fuse in limiter is working at 180kmh , once I remove the Trac fuse my traction light flashes on and off , and no more speed limit or traction control. :)
