I have a 1997 Mitsubishi Eclipse RS, i want to turbocharge it but i don't know what i need to do about the ecu problem. I've heard of 'tricking' the ecu but know nothing about it. if anybody can help me out in this area suggestions would be greatly appreciated.

This question is best answered by a search. We have been turbocharging these cars since they were new.
There's not much to trick on the ECU. 96+ cars will fuel cut when they see boost, so most people add a voltage clamp on the MAP sensor to prevent the ECU from seeing any value above 0psia.
Fuel is usually added in a manner the ECU has no control over, e.g. increasing fuel pressure via a variable rate-of-gain regulator.

'95 Eclipse TurboGS (garage deco) '95 TSi AWD (restoring a survivor) '97 Talon ESi-T (poor impulse control) '99 Eclipse RS-T (daily beater) '13 Evo X (mostly stock) '17 Sienna (Middle Aged Dad Mobile)
95 ECUs could care less if they see boost. Just don't try to use a 95 ECU in a 96+ car. It won't even plug in.

Never start a thread with such an undescript subject line.
