Ok, since the US market Lotus Elise uses a 2zzge w/ a Lotus tuned ecu. Would it be possible to swap the Toyota ecu for the Lotus ecu and actually gain the 10 hp and additional torque that the Lotus tuners achieved?

I thought it might be interesting.

Uhhh.... I think the guys at Lotus did a bit more than that for their performance gains.

im still trying to know how they did change the ecu setting, cause as far as i know toyota guys cant chip/reprogram there ecu, unlike the honda guys who can just drop in a "hondata" chip.

The "chip" - EPROM is on the CPU inside the ECU. They are programmable. It take more work to take it out and make a board to program it. Also you'll need a copy of the original program cause you can't read the program from the chip. That is the hardest part.
