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

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
