How does combo number one sound?

i would be worried about the rom tune without knowing if they have any celica specific (alltrac i mean) setups.
i love my '27.

Yea I read your sticky about the 5sfte. What is this "rom" you speak of? Is it an abbreviation?

What is a ROM TUNE? If you come from the domestic world it is usually called "chipping" the ECU. The Toyota ECU is fairly complicated with the CPU and rom (read only memory) being housing in one unavailable chip. Techtom however designed a solution several years ago called a daughterboard. This allows us to place the ROM outside the CPU, and allows us to change certain parameters inside the ecu.

OK, that meant nothing to me, what parameters are you talking about?
Here are the major benefits of the ROM TUNE:
1. eliminate fuel cut(s) (some MR2 ecu's actually have three fuel cuts)
2 eliminate speed cut (if applicable)
3. raise rev limiter
4. complete control of ignition timing table
5. unlocks factory "high boost" maps inside ECU
6. control of fuel table
7. more consistent behavior

Thats great, can you put a actual horsepower number on it?
YES. Multiple back to back dyno tests have shown gains of 17horsepower and 16 lb feet of torque on BONE STOCK MR2's. Plus turbo spool was 200rpm sooner.

What about modified cars? We installed a CT27 turbocharger on the same car tested above and A/B testing with the stock ecu showed a 22hp gain and 20lb ft. of torque with the ATS ROM TUNE.

Are these generic tunes? NO, each tune is based your YOUR PERSONAL modifications.

What about larger injectors? ATS can tune higher horsepower cars with CT27, TD05 or TD06 turbochargers to use 550cc injectors. The cost for this is $100 additional.

What if I change my modifications, will I need a retune? Minor modifications like intake, ignition or exhaust will not require a retune, however modifications like turbochargers, camshafts should. The cost for retuning an ATS ROM TUNE is $150.

Do I have to send my ecu in advance? It helps, however we do have an exchange program available in limited numbers. We will need your ecu back IMMEDIATELY after you receive your ROM TUNE so that we can turn around to rom tune others.

if you dont have a 3sgte swap, forget everything i said.
this wont work on the 5s.
the '27 will, but everything else is 3sgte specific.
