Auto ECU in Manual

I'm looking for a replacement ECU for a manual stagea. The owner isn't interested in aftermarket/tunable options, just a factory replacement.

There's not many options out there, and I have read a few posts saying that an auto ECU will work.

If this is the case, are there any tricks to making it start and run correctly?

Comparing the two ECU diagrams, theres quite a lot going on with the auto ECU eg: Throttle switch for idle/full throttle, a number of connections

to the inhibitor switch.

I have read that you have to trick the ECU to think it's in park?

Any help would be appreciated, if anyone else has done this.

Sorry I don't have specifics, but I ran my manual conversion on the original ECU for some time. I believe that bridging the park switch was the only thing required

Cheers, I thought that might be the case. I’m guessing it ran fine, no idling issues etc?

Mate, an auto s2 stagea or r34 ecu ( what is being discussed here)definitely have a rev limiter.

This is for a s2 stagea that have tiptronic. They dont shift up on their own when in manual shift  mode.

What conversion did you do that had a rev limiter not work?

All auto R chassis (and the crappy stag ones too) have rev limiters.

Of course they have rev limiters.

I can even show you the rev limiter in the factory ROMs if you really want.

Like a few threads ago you were talking about putting 25 pistons in a 26, then a couple of threads later going on about pin height difference, you showed enough there

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      R34 Skyline Sunroof Won't Tilt/Vent

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.

      It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣

      R34 Skyline Sunroof Won't Tilt/Vent

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
