Help with removing speed limiter on st205! Options

[Celica_kid_st205]

I have a swapped celica gt, with a st205 engine. I'm running 16 psi and for some reason my car tops out at 112 mph? I was wondering how I could get my top speed up. Help?

Take the ecu apart and find the circuit on the circuit-board that controls the speed limiter function. Not a difficult task, an electronics repair person/place may be able to do it just find somebody who is knowledgable in electronics

I'm an EE. Doubt that's possible. It's most likely a microcontroller , maybe some are FPGA based not really sure. But either one there's no circuit dedicated towards just the speed limiter. Its logic inside the IC. If you f'd with that it the ecu just wouldnt work.

For example most newer cars can be 'flashed' via OBDII. You're not adding or subtracting circuits you're just adding different logic inside the microcontroller.
