Project MUGEN Civic Type R

The Mugen Race use only ECU is an OBD2 but im not sure if it can be remapped - my guess is no. Im no tuner so i dont know exactly what he did but he clearly indicated that the engine is running quite lean with the current 240cc injectors. As per the Mugen ecu and how much fuel its asking for - we dont know :(

I think the ecu thinks i have much larger injectors to be honest. Hence why its asking for more fuel.
Im hoping i can get a set of these RC injectors and that solves all our problems. Anyone got a set :P lol

Well its important to know what injectors should be running with the ECU. THe ECU may infact just be used to a higher rail pressure to inject more fuel per pulse?.. It seems all ur 'tuner' has done is stick her on the dyno with a wideband in the ass and checked A/F. Possibly ajusted timing manually. DO u know the current duty cycle on the injectors?? Id assume if the ECU was expecting bigger injectors, it would be lower then normal. hmmmmmm

you cna't buy bigger injs and hope the mugen will solve your problems, it won't happen

Weq, would you like to speak to my tuner ?
Im no expert with injectors or know exactly what i need or what the ECU really wants?

Im just trying to get this thing tuned before a drag day on the 17th. ATM i cant do anything and im starving the poor thing ..

Andrew thats a pretty cold answer. If you can assist me on how to solve the problem that would be nice but i dont see any helpfulness to that post of yours .. :rolleyes:

Its OBD2. I have already proved and posted that mate

Nicely done mate..... all i can say that it looks better than a ctr...lolz.... :D

if u want to run bigger inj, u need a programmable ecu to allow u to do that, the mugen can't do that, simple as that.

Well do you know what injectors this "race use only" ecu requires ?

"race only"injectors?

Hmms well what can i say...
1) Find out the specifics on the ECU. What size injectors its programmed to run, at what fuel pressure.
2) Dump the ECU, get something aftermarket or rechip!
3) Piggyback ECU like unichip or e-manage or an AFC (last resort) with some injectors of ~400cc. U will need ignition control though in any case for its full potential.
4) (very last) Adjustable pressure regulator and up the rail pressures until u get rich enough. Possibly need a new pump to keep up with demands.
