Time For A Tune

Hey guys! I've got a 33GTST running 7psi on low boost and 11 on high with the supporting mods:

3inch down pipe following to 3.5 cat back exhaust

100cell high flow cat

Front mount intercooler

Fuel reg

Walbro 255 fuel pump

High flow turbo

Spitfire coilpacks

Dual stage boost controller

Now that I've got these mods I'm wanting to get a tune and a new ECU. I need to know a good place based on the Gold Coast to get a tune and what ecu to get. I'm heading towards a Nistune. I've heard about EFI in southport and what a great job they do on Nistunes and probably going to go them at the end. My car has the factory ECU so wanting to upgrade ECU and tune before going towards more power gains. Will I also feel any difference with a tune? If anyone knows how much tunes and ECUs cost including installing would be great! Thanks in advance guys!

You will feel a difference when you wind your turbo up to 24psi or whatever it is suitable for. You will NEED a tune to make it work. Have you fitted all of the above? If you look closely you will find your car already has a fuel reg. Will your afm and injectors cope with your projected new power level? Don't forget to put spark plugs on your list.

Do some research to find out what you have to do to Nistune an R33.

Just to clarify. Nistune do not have a chip for the R33. You need to find the appropriate Z32 ecu or similar preferably one that can control the VCT. Simpler but more expensive is to get a Link which will do everything you need and more including obviating the need for a bigger AFM (you will need a MAP sensor instead - and an air temp sensor).

How much power is claimed for your turbo? Check that its maximum is not more than your injectors can handle - otherwise you will need a set of bigger injectors. And how good is your front mount?

Was about $600 first time and $200-300 for the second touch up tune on E85 compare that to a top place in brisbane ( not sure if i can name) who charged me $1000 just to tune a very mild setup with a high flow..

Having said that i try to give the tuner a good package to tune, so one with new parts/combination so he doesn't have to dick around with rubbish, but he will likely tell you in the before tune inspection...

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
