The question of the the correct removal of EGR
 

If you simply remove the EGR system from the car, but do not disable it in the ECM, you will run into significant problems. You will likely run into detonation, the engine will run very poorly, lack power, and will probably run on the hot side as well. In addition, you will get a code 32 before running very long. If you recall from before, the ECM alters fuel and spark advance when it thinks EGR should be on. If no EGR flow is possible because you removed it, you will have a lean condition which will be further aggravated by advanced timing.
who removed in ECU?

No one.... It's not a reprogrammable unit. Either switch to a standalone or get an ECU from a JDM 7M.... I believe the JDM models have a governor though which limits your top speed. Why remove the EGR anyway? It has no effect on performance as it's not active at 70% throttle of more and has a number of positive effects while just cruising.

that is, it makes no sense to turn off electronic or rather to remove an electron will not work and does not affect the Working Capability engine.
