microtech are not as bad as everyone says. its just harder to get working on a rb. very easy to tune but very hard to wire into a rb. alot of people use the plug and play adaptor for rb25s hard wire it in properly and its fine a bit of a hastle to wire in but once done its worth it.

like i said before if the microtech was not given to me i would have gone a nistune or PFC

The model number implies its drivers, normally halved.

An LT12 can do 12 cylinders batch fire or 6 sequential.

Correct me if I'm wrong anyone..

I know its meant to be sequential but the last LTX12 I scoped definately wasn't sequential - that was using a 36-1 inductive trigger and factory inductive cam trigger on a 2/1JZ. Apparently microtech's cant use too higher tooth counts and which means on an RB they are most likely only using the 6-5-4-3-2-1 signal not both the 6-5-4-3-2-1 and 360 tooth signal like the factory/PFC do.

Hence why there is very few ECU's that I trust to use the OEM RB CAS for stable igntion control.

i've had microtech's on a few cars now, I think they serve their purpose, cheap to tune & simple, very broad in load points for tuning, best suited for drag cars and rotors. but if u don't mind turning the key a few times on cold days & warming it up for 5 mins then microtech will be just fine

if you don't ever plan to pass a emissions test, and you don't care about the microtech's timing drifts and you can be bothered with aftermarket aux's then go for it.

its just not the right way of doing things.

How well do they work as a piggy back?

I've an auto & I'm looking at a possible high flow turbo in the near future (nothing major, only aiming for about 220 - 230rwkw) & I'm a bit stuck on ECU choice.

Since no stand along aftermarket ECU works properly with a R33 auto (as far as I know from reading old threads), & some old suggestions was running a combo of SAFC + STIC, however the latter is nimpossiblebile to find. The other one was to run a Emanage Ultimate, but I found most tuners around my area dislike them for some reason, so no point getting it if I can't get a decent tune out of it.

I talked to my tuner about the issue & he reckons a micro tech wired in piggy back would do fine with a stock high flow.

Any opinions on this?

Can you explain in more detail?

I thought the harsh changes where due to replacing stock ECU which backs off timing before auto changes gear with a stand-alone aftermarket one, which doesn't do that.

But since you retain the stock ECU wouldn't that mean this 'back off timing function' is kept as well?

      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.
