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.

      Quieter performance exhausts (or muffler add-on options)

      Nope.    Grab a varex and turn it down as you get close to home, win win?

      Quieter performance exhausts (or muffler add-on options)

      By f00stx · Posted

      So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?

      The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.

      Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.

      Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
