Running an AEM V2 intake, Mugen header, T1R test pipe, Mugen exhaust, Mugen thermostat/fan switch/rad cap, Hondata gasket. 25% Honda coolant/75% distilled water. 93 octane only. We've got a Sunoco here that has a 100 octane pump, I wonder if that's worth running a tank full to see how the ECU likes it.

The Mugen PCM doesn't care about OBDII systems. It does not run the OBDII monitors. Yes it still comunicates to a Scan tool, I never said it didn't. Evaporative emmisions, Catalytic convertor, Secondary air injection, Missfire detection are all OBDII required monitors.
Seeing the Mugen PCM doesn't use a Knock sensor, Doesn't use the Rear 02( which is only there to monitor the convertor) I am assuming that the translation to english changed "Systems" to "Sensors".
I'm betting you can unplug any evaporative emmisions sensor or solenoid, the air pump, and the knock sensor and not cause a DTC to set.
Weather or not a Mugen PCM still detects misfires I don't know.

Red MX5,
An old fashioned jug element would work and have a ceramic former for the element. Simpler would be to work out the voltage seen by the ECU over the current shunt. Then replace the high amp circuitry with a simple relay and resistor divider to send the same voltage to the ECU.
I found the diagrams in the workshop manual. For each component of the engine management there is a test procedure which details voltages you can measure.
What are you putting the f20C into. It isnt a red MX5 by any chance?

I can guarantee that it does support and report OBD2 codes (as a result it interfaces successfully with OBD2 tools and state inspection computers).

I have the Helm manual, but didn't realize that the schematics had this level of detail. I'll have to check it out. Good tip!
At this point I have found and installed a used replacement pump, but I'll pull it off if I can find a sure way to fool the ECU. I also thought I might be interested in the Mugen ECU as a future upgrade (should I decide to run the car in ASP), but given all the confusion it doesn't look like a very good idea at this juncture.
Thanks for the tip.

I also want to remove the air pump but don't want a CEL.
By the way, I think the Japanese ECUs don't care about the air pump. It's a USDM thing. I didn't see it on the Spoon S2000, the one that was at AJ-R.
