I have a ECU with a chip I don't know what it is...

Have a friend that tell me its a mugen chip...

I would like to know the specs of it vtec engagement to fuel cut...

My chip: vtec engagement 6000RPM fuel cut +-9500RPM

 

Mugen made whole ECUs, not chips. If you are revving an unmodified engine that high, you will have issues.

 

can you tell me the specs of mugen ECU?

 

Mugen ECU's lower VTEC engagement to 4700rpm and raise the rev limiter to 9100rpm.

 

Mugen tuned ECUs for the specific setup that the car was running at the time. None of them will work properly with a setup that isn't a copy of that car.
What the settings are in the chip really depend on the engine/car setup.

Also, 99% of the "mugen" programs out there are simply someone taking a honda base tune, adding fuel and timing to the maps and claiming it's mugen. This makes them garbage. You'll end up with poor mileage, potential knocking and crap performance.

If you want to know what the chip is set, pull the chip, read it, then open the bin in an editor.
Anything less will be a guess.
