Yesterday evening I had my glovebox out and a lot of trim as I removing some old gauges and replacing them with new wiring and gauges, and in the process noticed that only had 2 screws holding in my ECU. As I am still discovering things about the car, my curiosity obviously kicked in and I took it down off the side of the interior of the car and had a look. A couple of the screws holding the lid on were stripped out a bit, so I took the top off and had a look. I don't know exactly what a stock rb20det ECU looks like inside, but I figured some of you guys here would, so here are some pics, what do you guys think? Stock? Modified in some way? The car performs roughly what I would expect a stock GTST to perform like.

Cheers

looks stock to me. that daughter board connected by a ribbon cable is stock.

the chip labled, "R32 F-TYPE", is the rom chip that gets changed when the ecu is chipped. it is a little hard to tell with your pics but as mentioned above, if it has been chipped there will be a socket soldered to the board underneath that chip, and the 28pin chip will be plugged into that. When nistune is installed it is plugged into that socket replacing the rom chip.

    • 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         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
