Is management needed here...

[NIZ30]

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 ), 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

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.

Anyone know people who are handy with a dyno in Brisbane? So i can at least see if i need to get this work done.

My car goes fairly good, but i think it's not going quite like it used to, or i am getting used to the speed. Not sure
