Is management needed here...

I know it is desirable, but is it needed? By this I mean will I greatly benefit from this? Could I be possibly harm my engine running how i am now?

I have one of those, "modified in Japan" cars. So I don't exactly know what has been done to it. What I do know goes like this...

Trust TD06-20G, Trust FMIC, Trust exhaust manifold, Trust wastgate (vented externally :cool: ), 5 puck button clutch, Inpul 260kph speedo, Standard computer.

What I also think it has...

Upgraded fuel pump, extra injector, something done to the management (ie no 180kph speed cut. And not brave enough to find rev limiter, it is not at the red line i know that).

It runs happily at 1.5bar. And goes fairly quick now.

I am just trying to justify the cost of this. If it is fine now, why bother? But will it go quicker and more reliably with aftermarket management? Also full boost comes on pretty late (about 4500rpm) if it improved this it would also be very beneficial.

I have been quoted $2200, installed for Autronic. Also is this any good/is there better for the price? has anyone else been in a similar situation and seen the benefits?

Gezzz, you've got a nice list of mods there. I bet it goes good.

OK, I dare say that you have got a remapped ECU there. If your running a big arse turbo and different injectors there is no way the stock ECU will handle them.

The R32 ECU's can be remapped to suit your mods.

I think the best thing to do right now is to find a good dyno (and operator) and run your car up on the dyno. This will show how the A/F ratios are, fuel pressure etc. From there you'll be able to tell if you've got to re-tune it. It would be worth the $50-80 bucks.

If you do need to re-tune it (I dare say the ECU has been mapped for 100 RON Jap fuel), then I think the best, and maybe the most cost effective thing to do is to get the ECU re-mapped again. I "think" some places can do it for around the $6-700 mark.

What does everyone else think about this??? Come on people, have your say :cool::P:P

im in a simliar situation

T04E on HKS manifold with ex gate. FMIC, bigger pump, gtr injectors

currently my management is a remapped ECU and HKS PFC F-Con. ive been considering my options with regard to management. basically YES GET IT TUNED! ive already blown the engine once hehe

anywa the options are remap or run a piggyback fuel controller like a SAFC or E-Manage

remap is good if you dont plan to mod further (is expensive to remap) piggy back is better if youre contiunally modding the car, however they have lmited control as they are only 'tricking' the computer.

it all depends on budget. my budget is relatively small ie 6-700

if youre able to spend in the 000's then go for a full replacement ECU, but expect to spend $3000 approx for fitted and tuned.

      Mistakes were made, my R34 Story

      Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!

      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.
