i want to know how mugen N1 ecu ?
is it great ?
any other ecu suggest?

 

Mugen ECU has a different motherboard then than stock ECU. It has a very fast processing speed so this unit is very good for acceleration and ON/OFF throttle response. However, due to different engine setup will effect the performance result, there are good and bad feed back for this unit. Some ppl on this board did achieve 10whp from the ECU but some ppl saids it does make any power at all. I will say it is good.

Theres ECU that you can tune it yourself like Hondata which is a very good idea but if you dont wanna fool around so I guess you might want to get something plug n play with no worries.

 

i've tried a mugen chipped p28 ecu on my 94 gsr. Tell you the truth, i felt noticeable gains as soon as it was in. The first thing i noticed was my car running a lot richer, throttle response from low end to high end was great! just driving normally, and not hammering, you could hear the intake sucking harder. But when vtec kicked, it would snap my neck back from the outrageous pull. Almost feels like a shot of nitrous. The down side to this is that there's No rev limiter. Also, gasmileage was very shitty! From what i hear, w/ this program, the lobes are open all the time, and may be damaging to your motor. not sure tho....... hope this helps

 

it raises redline... thats all i know.

 

When you say the lobes are opened all the time, do you mean the VTEC rocker arm pins are locked all the time? That can't be true because you described a VTEC switch over...if the "lobes are opened all the time" there would be no VTEC crossover.

Also, Mugen clearly states that the VTEC crossover has been altered to 4700 rpm from the factory 5700.

 

Mugen's ECU Vtec @ 4600rpm and rev limited at 9k.

 

... and you're right about the instant on/off throttle response.

 

I got about 185 whp with a Mugen N1 ECU, Mugen header and exhaust and cam gears and advance timing. I bought my ECU used so the cost wasn't that high. I really liked it.

 

Does anyone here still have a mugen ecu that they would sell?

 

I heard the mugen ECU kinda sucks with the USDM type R because it was designed for the use with the mugen race engines, hence the N1, so its not designed to work with the stock internals, compression, even fuel. For the same money you'd be better off getting a stand alone unit such as a AEM or hondadata for the same price and have better results and even duplicatge the mugen race proggie.

 

how about spoon ecu? sport,group A and N1

 

The N1 race series rules only allows for stock internals, so the folks at Mugen designed most of their performance parts to work closely with OEM parts. But you are correct about the compression and fuel.

The best ECU I've seen in action is a p28 chipped jun ECU. With the jun 3 cams, jun vavle train, and even jun pistons, this ECU kicked serious ***. Without tuning the car idled normal w/ no VTEC flutter (at change over). The JUN ECU is the best I've seen so far as a replacment ECU. Tuned this would probably be a sick setup

there are six very very small Microsoft employees inside of the Mugen ECU, that is how it works.

 

and for all of the us 2000 and 2001 r's you will loose your air conditioning.

 

regarding the N1 ecu's i assume the costly prices can be contributed through the usage of a new motherboard and faster processor. Has anyone actually tested a authentic N1 ecu versus a copy to see the effects since the hardware is not the same?

Yes a hondata is relatively in the same price range as the N1 ecu's, however the hondata i believe would be running on the slower processor. I would believe you could compare the N1 ecu versus the stock reprogrammed ecu to a pentium chip to a 486 that can be tweaked.

Or another analogy would be though the 486 may have the exact same programs and do the same functions as the pentium, the 486 obviously cannot compare to efficiency as the pentium.

I guess my question is do the N1 programs rely heavily on the updated hardware?

 

low end stayed prettyy much the same but once vtec engaged it pulled very nicely as opposed to my stock p72 ecu, expect to run rich and watch your MPG take a slight drop, nice program imo
