Turbo back exhaust, front mount intercooler and 10psi boost will usually be about the limit of the stock ECU without hitting the major ECU limits.

Usually this would yield you around 165-175rwkw. I made 170rwkw with a fairly nice power curve without hitting any ECU safety features.

Having said that every car is slightly different so you may still run into problems (especially on a cold night).

I always find it amazing how many people want to avoid getting an ecu... Ecu was one of the first things on my list. Makes such a big difference, not just to power but to drivability and fuel economy.

Why not get an ecu and find improvements everywhere?

thanx for the input guys, i DO plan on getting a new ecu, just the parts i have came with the car. living in a small country town kinda makes it hard to get the thing tuned tho, is it worth goin all out for a pfc, haltech or similar? im not chasing huge power, its my everyday car, just sumthin thats a bit of fun, maybe round the 200-220rwkw mark. my gf drives the car too, so i dont want it scarin the sh!t outta her :rofl2: any help would really be appreciated!!!

LOL, my missus was driving my car one day and a car that was on and off the brakes in front was giving her the shi ts, she said she wanted to overtake them and I said "go for it", she dropped it down to second and floored it, LOL, the car hit boost went sideways and she shAT herself, said my car was "stupid" and hasnt driven it since.

See that is a big issue that a lot of the guys living in major cities don't always understand. An ECU upgrade can be great, however if you don't have any one to go to makes it kind of pointless lol.

You can add an exhuast without hitting problems, well I didn't anyway.

I currently have all the basic mods (exhaust, boost tee, FMIC & POD) + a SAFC 2 & the car made 180rwkw when it was tuned about 1.5 years ago, no problems what so ever.

If you are not aiming for more power, SAFC is a budget option if you just want a quick solution to get rid of any R&R problems that may occur.

Do what it takes to get a Nistune fitted and tuned. Looking at your list if you don't need new injectors or afm you should be able to fit all that keep the boost low and drive to the tuner to get the Nistune fitted and tuned. As you will need a Z32 ecu you can get the nistune chip installed beforehand and then just plug it in and get the tune.

cooma is only an hour south of canberra. heaps of tuners here.

ppl will drive futher than that in sydney to go to their tuner..

Oh, I didn't really look where he was from, I just ment in general. But yeah if he is that close than no problem at all.

Get NIStune, wideband, a laptop and start learning :P

This. Learning to tune isn't that hard, just takes patience and practice.

The big diff is, if we f**k it up we have no one to go to to get it sorted. Have to put it on a trailer and then tow it 200km. Plus its not like you have a mate round the corner that knows how to do it and can show you. No safety net.

If we were to learn, we would be self taught and then some! and mistakes could be expensive.

Last thing you want to do is have to sell your car on Carsales - needs a tune!!!

Plus, I got a dyno + tune and it works so why muck it up?

I'd like to tune my own and have been considering getting a wideband and knock sensor, but then I'd need to use it, so on hold for now.......if anyone moves to town with the right skills, I'd probably do it.

Until then I stick to the mechanical stuff.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
