i am seriously considering puting an ecu in my s2000. The question that i have is, is the ecu for track use only, or can i use it for everyday use as well. Also, which would you get, the mugen or the spoon?

 

i would really appreciate it if someone can take 1 minute to respond, i really need to know if should get one or not. thanks!

 

This has been discussed before.
1Randyc have used Mugen ECU daily while before and he had no problem whatsoever.
And you can swap easily with Stock ECU without any problem.
The only drawback of Mugen is that it will disable the immobilizer so you need additional security measure if you don't have a piece of mind.
Unless you run full force on extreme hot weather, you shouldn't have any problem.
If he runs now with S/C with increased boost at 90+ weather without any problem, you wouldn't have problem using Mugen ECU at 90-100 temperature.

 

I'm currently running the Spoon ECU. Here are my thoughts:

1. Just like the Mugen ECU, it bypasses the stock immobilizer so you will need some type of additional anti-theft/security measures -- if you see fit.

2. It sets of the Chk. Egn. Light -- I've had the code scanned and it returned as a "manufacturer-specific" code from Japan. I have yet to fill any ill effects from this specific code that set off the CEL -- the car is running fine and I can still VTEC.

3. Performance. Under 3000 RPMs, I don't feel any difference. But from 3K and beyond, the car pulls much stronger and is VERY responsive off and on throttle (full and partial)! In fact, there's almost a "mini-VTEC" at 3K, and the "real-VTEC" at 6K which is much more pronounced and immediate!

Don't hesitate to send me a PM if you got any other questions -- I'll be glad to help if I can!

 

thanks alot to both of you guys!

 

Just to clarify 1Randyc never ran the Mugen ECU with SC. He "sold" (long story) it before he got the SC. Shaner ran the Mugen ECU with SC and he had no problems with it. The Mugen ECU does not give you a CEL. It is not recommended to run the Mugen ECU without also using the thermostat, thermoswitch, radiator cap, and anything under 92 Octane gas. The Mugen ECU retains all the factory rev limiter and safety checks. I honestly do not feel that much difference between the stock ECU and Mugen ECU. The base way to maximize the Mugen ECU is probably with the radiator upgrade, as well with Mugen CAI, Header, and exhaust. Since that is what it was tuned for.

turbo_pwr, yes you are absolutely right.
Sorry for not making it clearer, but what I really meant to say was, Randy is running s/c with extra boost( not with Mugen ECU, but with stock) without any problem to the engine so far, just running Mugen ECU on naturally aspirated shouldn't be no biggie unless it is melting hot outside.

 

As most here know I am heavily into codes:

. It sets of the Chk. Egn. Light -- I've had the code scanned and it returned as a "manufacturer-specific" code from Japan. I have yet to fill any ill effects from this specific code that set off the CEL -- the car is running fine and I can still VTEC.

What was the actual code set? I have a full 00-01 code data set provided to me through Honda. So what was the specific code?

I will get the specific code it throws for you Utah -- thanks for the help!
