Yer it does.. So does that mean I should or shouldn't get the dyno tune? Thanks

You need an aftermarket ECU to get a tune (unless you do a custom rom, but that sort of sucks). If you haven't changed anything on the car since the last tune was done, it might be a waste of time, however.

What ECU is it?

im not so sure about skylines, but with evos you can do a full tune with their factory ecu.

Theres always a good reason for a tune :) and generally theres always going to be some improvement made. how much improvement and what and the cost is what you need to weigh up.... Is it running quite bad? usually you can tell when its time for a tune.

Whats involved?? quite a lot of things actually but the basics are air fuel ratios, engine timing and boost. These things among others need to be set safe or be at safe levels or over time or a short time your engine will break or go boom. basically lol

The cost varies a bit depending on- Tuners pricing, Dyno time, alterations made during process and dyno type.

Ive done some research into getting a tune, as im also getting ready for a big day on the dyno, 2 days i think actually. The mechanic said it will be a day to alter the engine components like cams and fuel etc and full tune, then next day for cold start and road setup check. the price for the dyno tune alone is just under $1000 (not including installing cams and any mechanical work involved)

$900 to $1200 is a pretty fair range to expect for a tune.

One thing to note, a good tuner will only do very small alterations at the most. 9 times out of 10 they will save the setup, then wipe the whole ECU and start from scratch because they can never trust the current tune.

However you could also do a Dyno run or Power run.. (I just did one recently) it will give you power figures obviously, and will also give the tuner an indication on how your cars running and then he can tell you if he can make more power or if its running bad and needs re tuning etc etc.

only takes around 30 mins for a roller dyno and costs around the $100 - $150 mark

this is only based on my experiences over a few years in the scene.

skyline ecu's can't be tuned that easily. r32 and some r34 ecus can have a daughter board installed which can be tuned. (r33's have to use a z32 ecu or a r32 ecu, but will lose the VCT with the r32 ecu).

as for always getting a gain from a tune, if he has an aftermarket ecu and the tune is decent then there won't really be any gains.

+1. I wouldn't expect any gains.

However, for a new car it's not a bad idea to just do a power run to make sure whoever tuned it previously did a good job of it. Power runs are usually about $100.

Ok thanks for all the information about it and yer I'll just to a power run I think to see what he reckons I think it's going good but I just bought the car a week ago and just want to make sure it's all good.. So yer I'll get a power run and if it needs a full tune might do that but it's pretty pricy..

Thanks again

just ask around first, if hes a dodgy tuner he may say it needs one in order to get business ( i hope there arnt many around like that) also buy going to a top rated tuner that knows there stuff you know you are getting a reliable answer.

The dyno sheet can say its safe and all honkey dory but the tuner could also say it has more potential.

Like my one, its safe as houses, and has had a full tune a year or so ago by previous owner. But a new fuel pump its running a bit rich, and the tuner/s said it can and should be making a bit to a lot more from the power run.

As im new to Melbourne ive read a bit on the these forums and Ben at race pace is the man to see. thats where im going for my tune.

DVS JEZ has tuned plenty of Skylines with plenty of good results.

Helpful bloke too, has helped me out on a number of occasions and I'm not even in the same state as him. If I was in the same state, I know who would be tuning my car... thumbsup.gif

    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
