Dam straight Damo would rather do SAU them heroin gts4 are 4.1 because they share the same parts from the gtr i think r32 gtst is 4.3 because of the lack of torque from the rb20

ryan, my PFC doesnt display boost :thumbsup:

simon said thats not avail. on the rb25 version :)

as cubes said, cheap map sensor will sort that out, i bought the proper adapter.

yeah +1.

Also important to note the ramp rate the tuner is using......Shoot Out Mode (200) is a waste of time for the street, should be 150 or it will definitely run in different areas of the map (detonation city) on the bitumen and up hills.

definetly pete, 150 is our default ramp rate. depending on the style of power delivery but yea mainly 150. We sometimes lower it for just 1 run to really load it up to simulate going up a hill just to be safe.

just had Ryan n the guys at AUSSIE DYNO N TUNE tune my car today had a few issues with wheelspin but after putting ryan in the boot gave it a few runs and pulled a constant 300rwkw then on the last run pulled 327.4rwkw on only 19psi with only 18 knock level!!!!!

great guys down there fully reccomend them 2 any1!!

great talking 2 u Ryan top bloke, ill be back there with sum softer tyres n maybe biggr injectors so we can screw sum more boost in2 it maybe.....

hmmm, I might have it the wrong way around Ryan.

Is there more load (or brake on the rollers) at RR:020 (20kph/s) or RR:015 (15kph/s)

The higher the ramp rate the less load the rollers place on the car.

Then there's start speed, release time, end speed. Basically there is a whole lot of different combinations you can chop and change to suit the car and what sorta load you want to place on it. If a car is placed under light load but does a full power run, The true AFR reading will be false to a certain point as with power output.

hope that made sense lol.

yea sorry i didn't answer your question... rr:020 is a higher ramp rate therefore giving less load on the car...will show a slight increase in power. At the end of the day its just a figure. The dyno is purely a tuning tool. Unless your simulating near bang on road conditions then AFR's and power will not be accurate.

You were bang on the money pete. :thumbsup:

If for some reason you do need to tune with a higher ramp rate, eg. Wheel spin etc.. then a bit more care has to be taken with the tune and must be alot more concervative. So many other factors come into play.

yeah, I know Donan has changed his methods a bit over the years.

These days he tends to keep the AFR's on the lean side (around 12:1) but pulls extra timing out to compensate, up to 3 degrees (from around 20 to 17).

That's why I'm keen to get those adjustable cam gears happening at some stage so I can play with the valve timing a smidge as compensation for lost ignition timing.

One thing I like (and contemplating) about a decent set of cams is that they would dial out some compression due to the extra overlap and therefore allow me to keep my ignition timing up.

Anyone know someone selling a car for under/about $2500 with enough room for putting a wheel chair in the back ... like a wagon or R31, something with a big boot. Must be auto also :thumbsup:

just thought id post this,

fellow bmxer Matt Duncan lost his life in a car crash early this morning in Stirling North, just out of Pt Augusta.

i got the chance to ride with him a few times, and he was a shredder, always killing it at whatever he wanted to do.

RIP.

      Dry sump? Is that like where you don't put oil in, and leave the car parked in the garage because it's worth so much now and is like a beautiful museum piece? 😛

      Nissan Fuga Y50 2009 VQ35HR 313 hp / 230 kW RWD Also sold as Infiniti M overseas. Performance sedan built on the same chassis as Skyline V36 or Infiniti FX. Great colour with a fantastic velour interior. Very quiet and fast car (<6s 0-100), but can also be very economical for performance (long-term average consumption 11/100 km) I imported it five years ago, and it was well looked after. It has a full service history and a balance of ACT rego. There are no finance or PPSR issues with the car. Has all the features you'd expect from a luxury car. ABS brakes Stability control Traction control Dual-zone climate control Power and memory front seats and steering column Power passenger ottoman Smart key access Push button start 2 parking cameras Steering wheel audio controls Adaptive radar cruise control AFS aiming headlights Xenon HID headlights Security system Original Nissan remote start system Two original keys Dual-channel dashcam Blackvue 750 with PowerMagicPro for battery-aware parking recording Regularly serviced with a lot of major items done: Full new original Nissan suspension shocks throughout Performance CSF radiator Recent tyres, less than 10k on them New drive belt New bonnet struts Brakes recently done The car comes with a fully converted AV system with Australian GPS maps, DVD, and radio ($2k job). I really love this car, but I have too many cars and too many Nissans in the family, so unfortunately, I need to sell it. Priced at $18500 The car can be seen in Curtin. Thank you for your attention.

      JDM R35 Bought at Japanese Auction

      By 70RTY · Posted

      Here are a few photos.  The car is auction grade 4.5B and a genuine 1 owner car, as far as I can tell...  It has a full service history with only 31,000km in it.  I'd love to put a midpipe and tune on it but I am thinking that I'll retain its originality.

      I can be grumpy!  After owning one of the first GTRs in the country, I was bitten by the nostalgia bug and started the hunt for a GTR again.  While I could have bought a car locally, I wanted to experience the search for a car in Japan and bidding at auction.  The above videos document my experience to date and hope forum members find them interesting and informative.  I was after a low mileage, completely stock car in the launch colour and am pretty stoked with what I got!
