We do have an ECU upgrade available for your Scion. Since your ECU does not
have an easily replaceable chip we do require that the ECU be sent to us for
programming. Our ECU upgrade kit contains everything needed to pack and ship
the ECU to us and includes complete instructions, ECU location chart and our
programming specification sheet that you fill out so we know what upgrades
have been done to the vehicle. Next day air return shipping is also included
in the price. The part # to fit your vehicle is 65002, which retails for
$399.00. The kit is available through JET directly or through any of our
dealers.

Once we receive your ECU it will be programmed according to the vehicle
specification sheet to optimize the fuel and timing curves for your specific
modifications. For best results the ECU upgrade should be done after you
complete all of your other upgrades so we can program specifically for them.
We also recommend using at least 89 octane fuel due to the modified ignition
advance. Horsepower gains will vary depending on how the vehicle is
modified, but average gains are 8-10 horsepower to the drive wheels. If you
have any questions you can reach our tech department toll free at
800-535-1161. Our hours are M-F, 8-5 PST.

 

hmm. if only it was cheaper and eaiser to upgrade as more and more mods are done.

 

I came from a nissan forum and almost everyone there stated the JET reprogramming was garbage. I kinda take that advise with me to this vehicle.

Why it was stated to be garbage, I don't remember. I'll try to find the posts.

 

friend has an SI and he said its the best mod he did

 

coming from my last forum (mx6.com) everyone all had about the samething to say about JET.....dont waste your money! the only way they went as far as management goes was with the MEGA SQUIRT stand alone TOTAL control over everything,tuning on the fly EVEN with your PDA(optional software is needed but available) there are many options better than JET.....but yeah cracking your ecu and tuning it will provinde some extra HP but remember on our cars dont hope to see mega gains like you would on a boosted car or something it might not even be worth it aside from minor tuning to improve the bolt ons UNLESS adding a blower then itll help a great deal
