This ECU has specially mapped fuel mixture and ignition timing. 9000RPM rev limit and 6000RPM VTEC engagement. OBD2 sensors are eliminated. For racing use only.
N1 ECU 37820-XGS-00N0 $1500.00
Note: This is a complete Mugen replacement non-programmable ECU. Mugen does not produce or sell ECU chips, stock ECU's with replacement chips, or programmable ECU's.



thats what it says on the website, for RACING USE ONLY, will it hurt your car at all using it every day????

 

I wouldn't say 'hurt' but I think most will tell you it's unwise. First of all... it voids your warranty and it also removes many of the safety systems in place in the stock ECU. I believe there is also an issue with the link between your key and stock ECU that will require reprogramming or new keys or something.

 

The ECU doesn't "VOID" your warranty.

There also is no issue with the key.

It may remove some "safety" features of the engine however. So, yes, daily driving in the heat of a Texas summer in stop and go traffic could lead to something bad.

 

I have undertaken to delete my posts of any content here since the Management here has made this an unfriendly place for me and the club I founded and am President of, the S2000 Club of America, Inc. and they have claimed that my words have somehow become THEIR property and I think that's pretty uncool. If you would like to read whatever post, please contact me at greg@s2kca.com. Thanks

 

I guess it depends on your dealer, my car was fairly modded and I'm in pretty tight with the local dealers. They seem to be under the impression that it will "VOID" your warranty and since they make that decision and not MEAT then you might want to do a little more research. Like Greg said... it does disable your immobilizer which is linked to your key.

 

i live in jersey so the summers aint as bad as texas heat, i just wanna know how it helps performance wise, is it worth the money?

 

That's very subjective. 1500 for something that could be done for less with a VAFC and dyno tuning. Or get the AEM replacement and some dyno tuning. Some folks want it some don't. I would think that if you had to bring the car in to the dealer you could just swap out the ecu with the stock one. I would worry about the safety retards though. Also no immobilizer in NY Metro area is not always the best choice of course if they want it they will flat bed it.

 

Performance-wise, it's a benefit down low. I found myself having to downshift less after putting it in.

As for VTEC engagement point....we learned in our conference with Mugen that the rationale for the ~6000rpm VTEC engagement isn't an arbitrary thing. There was a great deal of study that went into this and VAFC's or whatever other devices (if there are any) which change the engagement point really sacrifice usable power...UNLESS...there is significant work to remap fuel. Simply changing the engagement is bad....mmmmkay?

I don't have the VAFC, so I'm not that familiar with what functions it performs, but I understand that they do very different things. The Mugen ECU isn't programmable...er...at least, I have never touched it after it was installed.

Also, it leans out the fuel, which would make you think that the car would get better mileage...that would be true, if your foot wasn't deeper into the gas pedal all the time!

 

For the record, I daily drove my car with Mugen ECU for a while until I sold it because of the Super charger.
I really loved how it transformed my car better especially on the standing start.
I didn't observe any problem, unusual noise or behavior with the Mugen ECU under any condition.
Use the search, I had my report long time ago on this. If you can't find it I will find it for you later.

The ECU is labeled for Racing use but that doesn't mean you can't use it on the street. For this particular application I believe you will benefit much on the street use because of the significant drivability improvement.
Stock ECU is too easy to cut back on power when it is not running under really optimum environment.
If you are using Mugen ECU, you may allow to strain the engine a bit under harsh running condition when it should take some load off from the engine. But I think you are going to be fine running this in New Jersey oppose to place where things can get pretty hot.
Of course if you want to take full advantage of the ECU, you may add other Mugen component like CAI, vented Hood, radiator.
Without above additional component, I would just be mindful of how the car is running under certain condition and not try to stress the engine too much under extreme harsh condition and you should be ok.

My main attraction to this ECU is the slight change of fuel curve in low-rev range.
You will less likely to bogg with Mugen ECU, and you will enjoy how your car can take off much better compare to when it was stock.

Agreeable $1500 is not cheap but this is a standalone replacement ECU with very easy plug n' play feature.
You will be happier with this oppose to doing CAI, header, or exaust. If I still have the Mugen ECU and living close by you, I can certainly lend it to you to try it out, but I am sorry that isn't possible. But that is also good thing about it, you can easily install or take out to try on another person's car without any difficulties. If you are under the budget you can group buy one and share it with your buddies. Use it for daily drive or use it for event specific like drag strip run, Auto X or on the track. It is very easy to remove or install.
