Tuning V35

[rs88]

Hi guys, I'm tossing around the idea of tunning my V35.

Any recommendations in Sydney?

Any ideas how much it costs?

Thanks!

Uprev is a popular tuning package

http://uprev.com/secure/

About $700

Then take it to a reputable tuner. I can't make any suggestions for a tuner in Sydney though.

• I would also love some information on Osirus ($700) versus Haltech Platnium Pro ($2500) versus Greddy e-manage ($$??) on NA setup.

Are the above management systems compatible with our Japanese based 350GT's, as most information I found are based on G35's in America and if so what are the options for future Forced induction routes ?

Here are some places with Dyno's....i guess that means they do tuning too.... Tunehouse, IS Motor Racing, Pulse Racing, Croydon Racing Developments, Autotech, CV Perfomance,Leading Edge Motorsport, Power Tune, Insight Motorsports

Any help from other experienced members would be greatly appreciated.

So much to learn.. : )

They are all very different systems.

Osiris is a re flashing cable and software

Haltech is a standalone, but will need stock ecu to run some things

Greddy is a piggyback

It's easy to get Osiris to work with jap ecus. Most are mapped, but it's possible to add cars too. It's 700US plus shipping for the tuner cable.

I would recommend DVS Jez at Gosford for tuning, but unigroup also tuned uprev stuff.

Oh, and regarding forced induction, uprev will do anything easily on a stock motor. The limit of uprev is that is has to run a afm.

It will run any size injectors if you want to run 2000s, but it still needs a afm. I found the stock afm was just about out of range at 6psi. Uprev sell a tweaked afm, that will handle significantly more flow, but the car will need to be tuned with it. That would be a 500 or so hp afm. So, anything you want to do on a stock motor, uprev will do. If you want 600kw on a built motor, then uprev isn't the best option as you need to run MAP

Uggs are only good for V36s.

Not relevant to OP

[SuperDry2013]

Thanks Alex for your helpful info and yes you are right about the ugg boots +10hp too. hahaha

[PN-Mad]

There was relvence before the post disappeared!

Now it just makes me look crazy...

[SuperDry2013]

Its okay...PN-Mad is already half Mad but just for you followers out there we had some lengthy spammed post about Ugg boots.... lol

You can get the Uprev Osiris from East Coast Customs in QLD, I tuned my car with the standard version ($500) that comes with 3 e-tunes (record data-log and rom files, send to East Coast Customs, they tweak the rom file accordingly and send back to you to upload to your ECU). Obviously its not the best or accurate way for tuning, but it suits my purposes and the tuner version ($700) has plenty more parameters you can adjust by yourself or a dyno tuner.

[PN-Mad]

For the extra $200 I think it's crazy not to get the tuner package, simply for the ability to take it anywhere you want and own the cable and rights yourself.

That's my opinion.

[81gSKy]

You do own the licence, the cable and you are still able to take it anywhere to tune, just that you can only tune 20 parameters with the standard version.

i am currently tuning my v36 with uprev tuner by sending datalogs to the usa, i did run into a problem tho. After i reflashed the ECU, hood open warning light is on permanently for some reason. other than that the progress is going along slowly, i will put it on dyno and get some numbers when its fully tuned.

Take a look at this: http://www.uprev.com/documentation/Popup%20Hood%20Reset.png

Can be a pain to do (sometimes takes me 5-6 tries), but it does work.

when processing this procedure, does the uprev cable has to be connected to the car? Or i can just get in and follow the steps as followed.

Sorry abit noob to this, thanks

No need for the uprev cable. That image looks like it's taken from the service manual, not made by uprev

My uprev flash has been completed. Very happy with the result. My car was running abit lean with abit of extra juice it made a big difference in torque at lower rev band so the car takes off much quicker. The engine is much happier to rev and tuner also switched the cooling fan system on at 95c instead of 100c.

My mods are stillen high flow cat, megan racing cat back, k&n filter.

Bought the uprev package from ebay. http://www.ebay.com/itm/Uprev-Osiris-Tuner-package-with-FREE-ETUNING-and-FREE-shipping-/141011901348?pt=Race_Car_Parts&hash=item20d4f6dba4&vxp=mtr

The seller is quick to respond and all you have to do is datalog with cipher and send it to him. He will send you back a modified rom file and as well as a back to stock rom file.

HEy Guys I Have 2005 250GT Sedan VQ25DD Engine, my Mechanic told me that i could not tune this car from stock, would this be possible with this osiris Uprev, has anyone had any experience with it with similar/same cars as me?

Cheers

Not possible. Different type of Ecu.

You'd need a piggyback like emanage. Wouldn't gain much for the money anyway.

[scotty nm35]

I don't think it's possible with the DD, you have much the same ecu as the M35 Stagea.

There was a guy (Baz?) selling an aftermarket ecu for the DD, it was a few months ago but I think he still has it. Look down the threads a while and see if you can find it. (Could have been in the Stagea parts section.) Otherwise you might be able to run an emanage ultimate?

If you are chasing more power, you bought the wrong engine. Perhaps start by cleaning the intake for more performance?
