Is there a trick to installing the Mugen ecu? Is there some special procedure or trick? I installed the Mugen 9000rev limit ecu into a Type S and we weren't able to get the car running.. Well.. it would only start up if your foot was pegged on the gas... it would stall as soon as you try to idle the car.. Any help would be greatly appreciated.

 

Yes there is a trick to it. I don't remember it though. I believe you had to ground the ecu and possibly cut a wire.

 

OK. at least that backs up my suspicion. Now... anyone actually know the solution? TIA.

 

you have to hard wire the fuel pump or somthing.

 

From King Motorsports:

"Installation on the US Market RSX-S (2002-2004) requires the following modification. Behind the glove box there is a fuel pump relay. The Green/White wire used by the relay needs to be spliced and a wire run to ground. "

 

You will have to ground out the fuel pump relay wire, as Kingmotorsports stated.
We have to do it everytime we send out a customer's ECU out to hondata for reflash, when we give them our loaner DC5-R ecu.
