Just Been Z32 Tuned

[senilykSkylines]

Hi guys, I have just had my gts25t tuned to 190rwkw Torque is amazing and power is great!

The mods are as follows:

-3" turbo back exhaust

-Walbro Gss342 fuel pump

-GFB Boot T

-Tuned Z32 ecu.

Running 10-12psi.

Stock turbo

Stock intercooler

I sent the chip away to a tuner in Auckland who did a pre-planned map for 190rwkw. I have not had it on a dyno and don't know if I will bother. I phoned a guy who ran a Dyno locally and he said that results vary greatly from each dyno. Some would read 140rwkw and another 200 rwkw. He thought with my mods I would reach 150rwkw on his dyno?! I thought it would be doing that with just a 3" exhaust.

Seemed pointless to me?

So, would it be safe to say that my car with those mods would be reaching 190rwkw? I know it feels definitely faster than stock.

Also, for curiosity sake, what cars could I match with running that kind of power?

cheers,

Dan

Take it to Nightspeed at Meremere on Friday night and find out, or even better Nizfest drags on Sunday

Given you haven't had the car itself tuned, much less had it on a dyno... anyone could guess. I certainly wouldn't be going claiming a power figure as you are at the moment. I'm not really convinced its a good idea running a chip tune some random put together without knowing your car.

Trust me this guy has had heaps of experience tuning many skylines and he has done the same tune for others... so he tells me lol.

I'm not worried, if you are happy with it then godspeed. Try it out at the drags, only way to know how it goes.

I've heard that more times than I've had hot dinners.

Plus at the end of the day all you have is a mail order tune. It will not be as accurate as one done on the day by the tuner as "mail order" tunes are generally more conservative to makeup for the lack of onsite work the cars dont shit themselves

I belive Tricky Tune is up your way. Get your chip tuned in the car at least and on a dyno ideally. And yes take a trip to Meremere for a reality check. OOps it appears Mr Tricky Tune has taken his skills to Australia. You will have to take your car to the guy who made the chip in Auckland (was it Andy?) and get him to refine the tune in the car and then carry on to Meremere!!

Yes it was Andy from X-tunes. From my understanding 190rwkw was a safe tune lol. I might have to travel down there to dyno it. I just don't know how worth it is since dynos don't sound very accurate.

You seem to be missing the point. The point of using the dyno is to make your car run optimally, a big or small number doesn't necessarily mean anything

yeah chuck it on dyno to make sure the tune is actually safe and good (a/f ratio).. personally i dont know why u would bother with a chip-in and risk engine failure.. does x-tune offer warranty/replacement if ur engine shits itself?

Not to sound like another hater here, as all it comes down it is whether or not you're happy with the car....but I was making 190rwkw on the stock ECU with a bleed valve controlling boost to ~11psi...

i have never had one pull over 180rwkw that was std on my dyno... but dynos vary.

[Trozzle]

Yeah exactly. It pulled that number on 2 different dynos though (one DD, and the other was whatever gives the style of printout Dr Drift uses)....and in all honesty, I can't say 100% that the ECU was stock. I never remembered to get it back off the workshop that installed the ViPEC...my silly mistake.

Also, my timing may have been slightly increased due to CAS being adjusted, but i don't know.

The dynos should have an accurate AFR plot, and before you go make sure the run will include knock sensing. IMO you really want to check those things to get some confidence that the tune IS safe. Every car is different and tuner will have made the assumption that everything on your car is working well, and that is something neither of you *know*.

You should be more interested that your motor is not going to blow up rather than if it has 11ty billion killawasps

[KiwiRS4T]

The important thing is to get the ecu tuned in the car. I have had Andy tune my car on the road and on a dyno - you don't need the dyno figure although the chart is handy but Andy has all the gear to properly tune your ecu in the car. The mail order tune should be conservative to be on the safe side so a tune in the car will get the best out of your limited mods. The 1/4 mile time will mean more than a dyno figure which is really only useful for comparing the same car on the same dyno after you have done some mods.

they are a shitload more accurate that you saying your car has 190rwkw because you 'think' it does...

I phoned a local guy and he told me that figures ranges hugely on different dynos... to quote him he said one might say 140rwkw and another 220! Sounds like waste of time to me.

My cousin said he dynoed his subaru and it came to 380awkw. He said he doubted it made that much power and he thought it was more like that power at the flywheel.

Everything is running sweet on my car as far as I know... there is no knocking sound etc, everyhting going smooth. Doing a premapped tune as opposed to a full dyno test retune is about $300 to $900... big difference.

Well sadly, he is an idiot.

Dyno variance in most cases is +/- 15rwkw, thats a reasonable range.

80rwkw, thats just plain horse shit

Put it on the dyno - and not for a rwkw figure.

Use it to see the AFR's, the power/torque/boost graph and so on. Will tell you exactly how the car is performing and is a MUST for anyone modifying

[Harey]

So u are happy for someone to guess tune your car, but actually putting it on a dyno to make sure afrs, timing and rough power are ok you are not?
