pangyau, i also had the same problem like yours, that time my evo8mr was "super stock" condition except decat and rear exhaust.
i brought my car to dyno, it was running too rich at high rpm, at 1.3~1.4 bar, too rich so it could not burn.
you can bring your car to dyno, and see the AF in the dyno chart.
u can do reflash, it should solve your problem.

H22-C,
Any review could you share about the unit?
Just PNP & remove the existing coil?... How about the wiring/socket?
Saw a few E owners at my place, their Okada burn due to few reasons.
As the unit is expensive, so I need to be careful on choosing.
Standalone for stock ride...? some said is wasted modded to me...
As the ECU are expensive...
yes, 100% PNP. no need to worry about wiring/socket.
i m using stock ECU, it makes difference. never regret. worth it.
