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.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      Jacks that fit under GTR lips that can reach the subframe?

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
