Mugen N1 ECU or Hondata K pro ECU

[M a i k e r u]

Hey guys,

I'm stuck on which ECU to get for my DC5R, So can you guys give me some Pros's & Cons For both ECUs.

Cheers

if you want programmable then hondata.....something cheaper plug and play then mugen

mugen ecu average 350km per tank on the dc5....

[Jingers]

basically do you think you will do more then I/H/E?

do u mind tuning it and finding a "reliable" tuner?

those two questions will answer your question

[M a i k e r u]

how much KW would the N1 Ecu give me?

[dang]

Hondata with a good tunner will be better than any off-the-shelf hit or miss ecu. If money ain't an issue, hondata definitely a better option.

[kookie]

is this ecu going to be a daily driver one or track one?

mugen ecu would prob be best on the track, because you will loose your immob when you fit this ecu on.

^daily driver

[noodleman]

if you end up getting hondata....do all your modding first...then get ecu and tune last....to save money and time

[air23box]

I reckon Mugen N1 goes well with full mugen I/H/E....if you have a bit of mix and match.....hondata is a better option.....can give you better gain after you fine tune it...but as Ed mention.....do all ur mods 1st then tune.....

Great, Thanks for the input guys.

Personally I'd get a Hondata if I had a K series...they seem so good! LOL

Can you please explain more about the benefits of the Mugen N1 H.O.A ECU on the track on a K20A2 (AUDM) engine?

Mugen N1 ECU
This is specially mapped to the fuel mixture, ignition timing, and combustion. The rev limit is increased to 9,100 rpm from the normal 8,400 rpm, and the VTEC valve timing changeover point is lowered to 4,700 rpm from the normal 5,300 rpm. It is highly recommended that reinforced valve springs be fitted if this E.C.U. is used.

N1 ECU [37820-XGS-00N0]
S2000 (2000-2003) $ 1,628.00
N1 ECU [37820-XK5-S0N0]
RSX (2002-2006) 2002-2004 Type S, Type R $ 1,320.00

From my limited knowledge, The stock K20A2 head & bottom end is capable / safely rev up to 8600RPM.

The Mugen N1 H.O.A ECU is tuned for a Japanese Spec motor which has different internals and compression than a AUDM engine. The ECU tuning should be different between JDM & AUDM spec vehicles but most Mugen N1 H.O.A ecu is a one size fit all fixed ECU map which cannot be altered by the end user. The suitability on the usage of the ECU is very highly dependent on your vehicle modifications.

One would think using a one size fit all map would not bring maximum potential from an engine unless it is the exact configuration that the map was tuned for.

yes, but this forgets that the factory ECU is not operating at optimum power, and is a *compromise* tune (power vs economy vs engine longevity)...

therefore a one-size-fits all CAN be an improvement over stock, given additional airflow modifications...

the same way when i fitted a generic Mugen chip to my Integra ECU it improved power and response, simply because the stock ECU was so conservative...

[tinkerbell]

but that said - if you are seeking *maximum* power rather than simply *more* power, a tunable ECU is the only option...

Agree.

Look at it from a financial stand point. You would want to maximize your return on investment. Buying the ECU to bring your engine to it's maximum potential instead of having just a gain from stock. They both cost around the same.

The stock (AUDM DC5) cam shafts do not make alot of power in the early 8000RPM range and no power past 8600RPM let alone 9100RPM that the Mugen N1 H.O.A is revving to. Assuming that this is all done in a stock k20a2 engine.
