Have anybody Upgrade Jet Computer Chip ?
Is Jet Chip better then Apexi V-AFC?

 

This has been discussed, and the overall verdict was negative:

I have been reading the same bad reviews on other car sites, as well. One MR2 owner claims that Jet sent him an OEM ECU with a Jet sticker on it and no other changes.

 

I would definately not purchase anything from JET. My friend had one in is 97 Prelude and it was big hassel. The first time he got it back the car wouldn't start. Then after waiting another 2 weeks he put it in and it seemed fine until he was cruising on the higway and every warning light on the dash lit up. Then after that he would get different warning lights at random times. All in all it was a bad purchase.

 

When new to the "import scene" I put one of these on an old 90 TT I used to have...there were some gains but once I switched to a JWT ECU it was like night and day.....Jet performance sucks big time......don't buy anything from them.

 

How is Jet selling an "upgrade chip"? There are noremovable chips inside our ECU... that's why I swapped out with a Mugen ECU
