power steering could be a few things. could be the pump, could be low on fluid or could be a sensor. if the steering goes heavy when the speedo drops out then it could be to do with it having speed sensitive steering, in which case finding the issue with the speed sensor is the place to start. it will either be a loose connection or a dodgy sensor unit. it also comes down to whether it is just the wiring from the ecu to dash that is causing the speedo to drop out, or whether it is between the speedo sender unit and the ecu. either way, electrical issues are a pain in the arse.

speedo sender unit is in the gearbox. if you get under the car you will see some wires coming out of the gearbox. there will be 2 lots of wires, 1 lot is speedo, the other lot is the neutral switch. with a multimeter you could tell which is which (easier if you have someone with you to put the car in and out of gear with the ignition on (car doesn't have to be running though). but you could simply check all the plugs and look for damaged wires.

Speedo sensor is near the tailshaft end on the drivers side of the gearbox/transmission.

Disconnect and reconnect the plug for this, then in the engine bay near the fuse box there are some plugs near the radiator, disconnect and reconnect these. These plugs connect the speedo to the dash.

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
