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

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
