Hoping someone on here can help me out.  I was troubleshooting an issue where my 1990 GTR all stock, was losing power when coming to a stop.  Started up just fine, consistently died when coming to a stop sign.  Anyway in troubleshooting, I removed by AFMs opened them up and put fresh solder on the contacts and removed and cleaned out my IAC valve and installed a new gasket (there wasn't one before).  After putting everything together, the car started but then immediatly died.  It would start but die almost instantly and wouldn't idle.  I adjusted the IAC idle screw but no matter how far in or out I adjusted it, I got the same result.  Start then die.  The only way the car would stay on was if you constantly pumped the gas pedal.  attached my ECU talk cable and got an error 21 for Ignition signal.  Still a problem to look at, but don't see how it could relate to the car not idling and shutting off immediately.  Open to any suggestions!

      RB26DETT Sketchy boost mod?

      By GTSBoy · Posted

      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 😂

      Cas issue

      By GTSBoy · Posted

      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.
