Yes, I know ppl will tell me to search, but I tried and there were no topics having them head to head

Anyway, I know the kenji p28 ecu is probably cheaper but I was wondering which one is Better ...on kenji's ecu, the dyno plots show lots of midrange gain but little top end gains. Is the mugen ecu like this as well

And finally, do kenji make a custom ecu similar to mugen's program?

Thanks, and hope to stimulate some discussion

 

They are drastically different in specs, I don't think you can say which is better. The question is what suits your driving?

Can you handle 4,400rpm vtec x-over w/ Mugen? (Or was it 4,700 rpm)
What about revving all the way to 9,100rpm? (Kenji can custom set rpm limit).

Having experienced Kenji's ECU, it's a damn good ECU at a great price. For me, Mugen would've been a nightmare w/ such low vtec x-over. (I don't want to be in vtec on the freeway all the time.)

Lastly, for the price of Mugen ECU, you can get a custom Hondata setup or PowerFC. I'd rather have the latter.

 

First of all, Mugen's ECU (the REAL mugen ecu) runs at a different clock speed. It processes information from the car at a higher rate than the honda (i.e., p73, p28, etc) ecu's. So you can't really compare these two ecu's, since one is doing things at an entirely different level.

Also, if you had searched, which i doubt you did, you would have found 100's of threads about the mugen ecu and how it is 'different' than getting a obd1 ecu and chipping it with a new program. The mugen 'program' is nothing special, its the hardware that runs the program: that is what you are paying for.

In any case, 4700 vtec xover, 9100 redline, supposedly running very rich (after seeing mugen mike's dyno, i'm not so sure anymore!)... do you want those things?

I don't think you know what you are really asking for. Better search and gather up enough info to ask a more detailed question. 1 ecu vs another, especially ones with such wildy different specs, is a difficult comparison.

I know all that stuff that you have pointed out...don't jump to conclusions...I read

What I want to know is HOW much more power does mugen make

 

That was already answered as well. Mugen makes its power up top. Kenji's makes it in the middle. It's not about which one makes more. Its about where you need it.

 

The ecu would really depend greatly on your set up and what mods are on your car. Comparing them ecu to ecu they are essentially the same, when you compare them to a certain set up one might be better than the other. Please state you mods or future mods and maybe someone can help better explain the benifits of either.

 

I have a DC JDM 4-1 and carsound cat, and spoon n1 (will be getting T1R) b-pipe soon

 

I ran the "real" Mugen N1 ECU in my car for more than a year with differing mods.

At first it was with intake, header (mugen) and exhaust (mugen). With those mods I got around 185 whp. The car ran great albeit rich. Because I had the JDM Mugen exhaust and didn't at that time have access to shorter custom catalytic converters - ran a straight pipe. Even though the straight pipe made my back bumper a little dirty - the car ran great with a nice fat powerband.

The lower VTEC xover is a good thing - more torque where you need it.

I took apart the ECU and can vouch for the fact that it's construction is top notch and very different from other ECUs. All the chips are encased in epoxy - I suppose for vibrational resistance. You need to get the jumper harness for 99+ Type Rs. The only complaint I had is installation - with the jumper harness and the larger size of the ECU it was difficult to get it back underneath the kick panel cover if you don't have the 98 ECU mounting plates. The OBD2+ ECU is much smaller and mounts differently.

 

Thanx for the review

 

More then likely the epoxy was used to hide what components made the ECU and to keep people from copying them.
