Mines Ecu's

That has little to do with the "Mine's knock control strategy", such as it is, so much as it is typical for old Nissan Knock sensors to be non-functional. "Mine's may well just copy paste the normal ignition map onto the knock map (which is typical stupid 90s styleeez), or they might actually have a few degrees taken out. But if the knock sensor doesn't hear anything, the ECU doesn't do anything.

I have deliberately provoked knock on both an RB20 and a 25Neo and not seen the ECU do shit.

I'm not surprised given how old these ECU's are. My Haltech pro plug in can't even do knock control. Sure its listed in the spec sheet and when you go in the software you'll find it, but it's garbage. It wasn't until the Elite ECU's that the knock control actually worked as intended (provided you also had knock ears to calibrate/verify what you were seeing in the ECU data).

I thought I would come back to this. No-one with more than 0.5 functioning brain cells has ever thought it was a good idea to use a Mine's ECU in anything at any time. They are a fool's errand.

We have 100 octane fuel here in Adelaide (united, portrush rd) I believe it’s 98 & e85 blended. I remember using it profusely in my early turbo days. 
 

If someone had 100 ron fuel, would this make the mines ecus a possible choice?

I’ve always wondered, cheers

100 is hardly sufficiently better than 98 to make it worth considering, especially when it's only available at that one spot.

I just don't know why anyone would consider a fixed, unknown quantity tune when you can just put a Nistune into a Nissan ECU and make it do what you want it to do.

Yeah I agree, those pre-tuned ECUs from the 80s and 90s are a pretty dangerous thing, a bit like the flash tunes many modern cars allow. They assume everything in your 30 year old car is working perfectly and remove most of the safety margin that nissan built in to give you a couple of % more power.

Since the ECU didn't control boost they can't make a major difference like you can get in a flash tune for a modern turbo car, eg a diesel ute

I've got uprevs in both my N/A Titan and Fuga and can't feel any difference in the power delivered, and in both cases they are a bit safer because there are wide band o2 sensors from factory to do some adjustment if there are fuel delivery issues.

Well you can’t nistune every skyline ecu as we know. 
 

10 years ago, I had a mines ecu and a copy of everything it was tuned for, which matched my car perfectly, and easy access to 100ron fuel, and still people said don’t use it. Didn’t make sense to me. Still doesn’t. If you use the wrong fuel for your tune you’ll blow your motor, that’s always been a fact.
 

but yes correct, I wouldn’t chase one now, but if the circumstances were fitting I don’t see why they’re the paperweight everyone claims them to be.

Nobody cares about R33s.

And if they do, they can always use an R32 ECU for Nistune.

At this point why bother trying to buy an R32 ECU + Nistune board + Nistune license when that gets you most of the way to a Haltech E2500 or Nexus R3? I'm probably biased though, I decided I would rather put the energy into trying to do a true port of the factory tune to Haltech rather than mess with Nistune.

      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.

      R33 GTR running -9 with no tune

      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.
