- How will the various functions / capabilities of ECUs change (if at all) with increasingly complicated vehicles coming out of the factory (e.g. from R34 to R35 GT-R; advent of variable valve/camshaft timing; drive-by-wire throttles; CAN BUS systems developed by the vehicle manufacturer)? E.g. does this mean owners have to opt for more capable (read: expensive) ECUs to work with these modern vehicles, as opposed to piggyback options, or vice versa (is there less scope for ECUs with multiple parameters with modern cars)?

- How would JEM plot the various ECUs on the market according to cost vs. capability, and hence which ECUs fall into the resultant quadrants, i.e. high capability, high cost (professional / overkill); high capability, relatively low cost (bargain); low capability, high cost (rip-off); low capability, low cost (on a budget).

- Any emerging trends in ECU design, e.g. advances in logging, ability to adjust settings on the fly for extended track work?

- Why is it important to have someone who is trained on my specific ECU work on my car? If I take it somewhere else, "what could possibly go wrong?"

- Any interesting anecdotes about ECU setups - any catastrophic failures from a POS ECU? Any situations where an ECU meant the difference between winning a race or retiring, etc etc

Cant wait to hear these answers some great questions right here :)

Hope I can get my tax in nice and early, might be able to book the 33 in for the haltek while im there :P Without the wife knowing of course. Which may be hard cause she will be comming with me.

My question for Adam.

What makes some factory ecus tunable eg nistune, cobb, vcm suite, ecutek etc whilst others cannot be done.

Is it a case of people haven't developed a software/hardware package for certain ecu types or are they impossible to crack the code?

Great!

Requested ECUs up for Adam to discuss are...

Apexi PFC, PFC D-Jetro, Nistune, HKS F-Con Pro-V, Adaptronic, Motec & Haltec

Any others?

I'll throw mine in Syvecs S8, and my usual tuner has just released his EmTron at the recant SEMA, as well as the there is a lot of talk about the GTR specific Morristech Black Box M3

    • 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
    • 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.
