How Long Does A Good/safe Dyno Tune Take?

In the next couple of weeks I'm going to get my car tuned in Sydney.

I've already picked the tuner and run-in the engine.

I've been given the choice of two different tuning options.

I can leave it for just ONE day or get a more thorough tune, taking THREE days. Of course the longer tune covers more and costs more.

This car is a daily driver and will rarely be used on the track.

Mods are dump pipes, new turbos, Power FC, 600cc injectors and fuel pump rewire.

Is there any point in going for the three day dyno tune? Can I get a safe and strong tune in only one day?

Can anyone here say they got a benefit from going for the 3 day tune?

ask the tuner? 3 days sounds a bit extreme

you dont really need to do cold start, idle and hot start with the PFC they work out the box flawlessly

so if they come back saying they need to leave it over night for cold start, its not really needed

the only time i would approve that level of cost and time was if they did wideband on the road test

a dyno tune is great and all but the full picture is on the road wideband tuning

as it will knock differently on the street (engine load different) and light cruise touch up

while doing like 80kmh in 4th, 100kmh in 5th, 110kmh in 5th etc

nice and easy on the road with wideband

3 days on dyno - excessive

for that i would ask and expect every single IGN and INJ map number to be changed

depends on who the 3 day tune is with. some charge money for doing nothing, others spend lots of time on cold start and warmup, with a power fc thats not really needed.

I could tune that car and get it going good in under 2 hours.

as long as everything is setup, a pro tuner said to me yesterday which has really stuck, the setup is 95% of the tune, the dyno work is the easiest and fun part which really opened a can of worms for me. "if your on the dyno for longer then a hour or so then you have not got your setup right or you don't know what your doing" hmmm he is right

power fc = eliminate setup time because they are engineered for the particular car.

Yeah good tuner should be able to get a tune done provided there are no "dramas" in 2 hours

DrDrift has done a great tune from scratch with my new setup, I could only book him for 2 hours on the day when he was doing a Queensland trip and im sure he spent quite some time working out a couple of boost leaks (my fault) :)

PFC and 3 days for tuning is def excessive

Thanks for the replies guys.

The tuner has said that they will test the individual NISMO injectors (for spray pattern and flow) if I send them up before I get the car tuned. Then install them on the day.

As far as what the extra days in the tuning shop will cover... the tuner didn't say anything about road testing with wideband. All he said was that it would be a proper or peak tune. Would a wideband road tune really take that much longer?

to me it sounds like he is trying to screw you out of some money for work not done.

if the car was there for 3 days how much actual time would they be working on your car? 1 hr per day?

what power are you aiming for?

unless you are over 400 rwkws i would say 3 hrs at a max

so maybe rethink your dyno choice for now.

I don't think the tuner is trying to say the car will be worked on for 3 days SOLID.

Most likely just two or three hours more than the main tuning session. It's just that those hours would be spent on the following days. Pretty sure he's not trying to rip me off, I just don't know if there's any "value" in that extra time. It's a daily driver with fairly common mods.

      Thanks for your insight, it being basically useless will impact my decision for sure. I thought it may help the engine breath better I guess. But then again, I have also been told that tuning an RB20DE is also not worth it. Exactly, we follow EU Regulations. There is a bit more leeway on older vehicles. My Porsche 924 came without a cat from factory and managed to pass, they still mentioned that I have quite high emissions on it though.

      My apologies, I stand corrected. Thanks for registering to mention this! And thank you for actually reaching out to the council to clarify. This is the sensible thing to do and the opposite of what I was alluding you were doing. I may have seen too much outrage and hate being fueled on the internet and it has made me a somewhat cynical old man. Sometimes it is easy to forget that there are real people behind websites and accounts. In my defence, CarExpert and CarExplore do read quite similarly at a glance. I shall try and do better in the future. (Please stick around to get the latest scoops on dealing with old Nissan shitboxes )

      Don't bother. The poor little RB20 doesn't make enough gas flow to challenge the flow capabilities of even the littlest cat, and you won't make any extra power, and all you'll do it soot up your rear bumper. Plus....is Malta not runing under Euro regs?

      Hey Daniel, sorry to hear that and thanks for posting up for us at a really hard time I only knew SmoothLine through the forums, we never met as we are based in different states, but when he was most active on here he was quite a while back so not many of the current crowd might remember him. I am pretty sure he was active in the Queensland SQU club but that is defunct now too (times are changing and we are all getting older). Farewell SmoothLine!

      Turns out depending on whether the car was equipped with TCS or not there are different signals coming to the dash, meaning there are different speedo clusters.  Wired in a speedo calibrator box from aliexpress and now works fine.
