Tuning A Gtr

[frankxinyu]

hi,

im just very confused right now about tunning a GTR........the tuner i prefer does not have a 4wd dyno, and he is going to take the front drive shaft out and tune my car on RWD mode.

would this actually affect anything on my car??? or does it do anything to Attessa system at all??

any info would be greatly appreciated.

cheers

That is the proper way to tune a GTR on a 2WD dyno.

As long as the fuse is disconnected and the front propshaft has been removed, you should be fine.

How come ur using someone to tune ur car when they dont own a 4wd dyno? Maybe take it to somewhere that has a 4wd dyno and then u dont have to buggerise around with removing the driveshaft.

P.S frank, was over at dan's picking up some parts last nite, and gotta say lovely car u've get there mate

nothing to worry about. many tuners only have RWD dyno. 4WD would be prefferable, but if all he has is RWD then disconecting the front prop shaft and running the car in RWD is no problem at all.

thanx guys!!!!

yeah, the tuner was going to hire a AWD dyno, but it is no longer available...

so we are goning tune the car on a RWD dyno, followed up by a road tune.

Noy, was gonna pm you for some advice...thanx man

i know Richo is a really good tuner( got things done by him before), but he hates Power FCs as anything........

i am gonna get Gavin Wood and Matty Spry to tune mine next week....

once i get Motec or HalTec with other mods, i will bring it down to Richo, and then he will be gald to do it.

another thing came up in my mind,

would the load be different on the 2wd dyno?? but the road tune should solve this, shouldnt it.

cant fault matty spry!

why would it matter if it was on a 2wd dyno or on a 4wd dyno, they are not awd they only use the front wheel drive when the rear wheels brake traction so really they are a RWD car untill the rear whells spin

not true at all. do you own or have you driven a GTR? AWD is computer controlled and is engaged under lots of different circumstances. a lot of the time there is some amount of FWD being engaged.

Tune it in RWD, it doesn't make any difference, there is no need for a road tune except to setup the accel pump settings.

further to this the 33 & 34 gtr's always have some amount of front wheel drive, hence why u have to pop the front drive shaft to put in constant rwd
