So far this is what i know:

1) Connect the Apexi map sensor (included in kit), if you have an r33 find the sensor that runs the stock boost gauge then run a T peice of the hose that connects to it. Then run the hose to the Apexi map sensor. If you dont have an r33 then use the hose that you run your boost guage off. Next you need to connect the apexi map sensor to your PFC (cable included and there is only one in the kit that will fit).

2) Connect the apexi boost solenoid, simply replace the stock solenoid with the apexi one. NOTE, you may have to change the posi of the ports on the solenoid depending on you setup. (see the guide on the US apexi site for the AVCR). You plug the apexi solenoid into the plug that the stock solenoid used. If the plugs are not the same it probably means that you have a solenoid for the GTR and you might have to cut the wires and solder them.

3) Tuning, go to the boost menu on the hand controller. Set the desired boost level in BAR. Go for a run under good load in third gear. If you do not get the boost you wanted then increase the base duty, if you over boosted then retard the base duty. NOTE: If you increase the base duty too much then your boost controller will spike, but if you dont have enough base duty then you wont come on boost hard enough. You dont have to get it exactly right though as the boost controller will learn the right boost curve after a couple on runs.

I am in the process of doing the above and I hope it all makes sense. If you have any further questions about the install then send me a PM. Chances are that I would have had the same problem.

    • Duh... to answer my own silly question, it's actually described in the FSM... ...400 pages away at the end of the manual, for RB25DE/DET signal descriptions, it cites the TPSwitch signal action, is dependent on the TPSensor value ~ this tends to infer the builtin POT voltage signal is the primary, and the switches are fallback/secondary should the POT fail/TPSensor signal lost (and switch alone with no TPSensor signal allows for base idle speed setting).... makes sense... they (TPS units) used to fail/wear the POT with time, they're not exactly built to last ~ having the switch as a redundancy gets around this...(or, it's less likely both signals would be lost as they're on different power rails)... and of course wrt RB26DETT, you have to electrically disconnect the IACV solenoid from the harness, to defeat idle air control...  
    • Dose is unaware just how much fun 145-150kw would be in a 2.5L NC MX5. It would be one of the most fun things to drive to ever grace SAU.
    • Same thought crossed my mind ~ depends on how one connotes 'stalling'...ie; gets a rough/stumbling idle as it get warm until it stalls... or... idles ok and simply falls-over when it gets to temp... ...you can test the whole circuit with a couple of resistors ...unplug coolant temp sensor, bridge terminals with a 2K7 resistor (ECU will do cold start), or with engine warm bridge with a 330R resistor (ECU will consider engine to be at normal operating temp)...it's a quick way to check wiring integrity/ECU response when you don't have a multimeter handy ...
    • They also make them with the motor mounted on the side 
    • Just be warned that that turbo will not be a direct re-fit to the car. The exhaust housing is, of course, in the same place. It has to be - it's bolted to the exhaust manifold. So the dump will fit up. But the centre housing is not as long, so the comp housing will move backwards. This will affect both the turbo inlet and the outlet. There is fab work that needs to be done. Yes. it has one, it should have one. Paper gasket.
