Anybody have an different ecu like a AEM computer or spoon ecu... etc. Do they work or are they a hassle?

 

Someone on this board installed a Mugen ECU and lost top end power, but I believe got more power mid-range. He also had mugen exhaust/headers, I believe.

 

What's a "hassle?" AEM or another "standalone" will have to be programmed for your vehicle and your mods. Spoon and Mugen can't be tuned and may or may not make more power for you and your mods, gas, environment, etc.

You might want to search for a specific ECU for more info.

 

By hassle i mean do you upload pre-designed programs for your mods or do you have to program everything yourself from scratch.

 

They are preprogrammed from the manufacturer. They aren't customizable at all. So they are no more of a hassle than an OEM ECU. The programmable ECUs from Hondata (if they have one for the S2000) are probably pretty tricky, and they require special equipment (from Hondata).

You can buy "piggyback" computers that interface with the OEM ECU, and they are programmable. Some of these can be pretty difficult as well (i.e. AEM EMS), but others are usually not (i.e. Apexi V-AFC).

 

The EMS is standalone. It doesnt piggyback.

Hondata doesnt have one for the S because our ECU is some bizzarre hybrid OBD-IIb. Nothing else like it on Honda's. Even the RSX ECU wont convert.

Too bad too, Hondata's stuff is nice.

The only good piggyback is the HKS PFC F-Con. They make in the JDM but not UDM. They make the equivalent of the Vafc but no Vtec adjustment.

Oh well!
