remembder guys they are inaccurate upto .4 of a second at worst, .2-.3 on average  :P

What a load of hot c0ck!! have you got one??? we proved that set-up right they are accurate within 0.02 and 0.1 MPH. Dont believe me then ask 2rismo and Bu5ter as i proved it to them at Compak Attak.

by the way...we use a pro RR as we like the data logging functions it has.

i used the data logging one a few weeks ago, seemed quite accurate, only did 0-100 though since we were on public roads.

also the rev counter function is not quite correct, it sensed 7000rpm when we were really at around 6000rpm, so started flashing all its shift lights too early, but who cares about that function anyway...

also tried an older one with the small red display (its in my glovebox atm) and even if calibrated correctly sometimes it comes up with whacky figures which are way off ie more than a second or two!

maybe i should try them both at the same time..

dont these devices rely on you knowing the exact laiden weight of the vihicle, if this is so then you would need some sort of weight station to get an accurate figure rather then guessing, aswell as that the cars wieght is also changed +/- 50kg due to petrol

just my thoughts on posible inacuracies

I have the original red LED display model and for 400m testing weight is not needed to be entered as it measures G force to calculate your time.

Entering weight was only needed if you wanted it to calculate horsepower.

With the original model I had the hardest thing was to get it to sit correctly which would give inconsistent times if not 100% level on the windscreen.

I read a review in Zoom I think and they mentioned this problem had been eliminated and accuracy was pretty good too with the latest models.

And if people want to weigh there cars I have never been charged on a weigh bridge as I dont want a printout.

I just drive on, look at the weight,and drive off.

buy an rsm sharky ..it does 1/4s(if u buy gsensor) .. rpm ..speed.. voltage and for 270bucks ..i seen cheaper this week on ns.com for like 240 ..... much better unit i reckon for hte money.....the gtech stuff is pretty expensive and pretty vague in terms of results.

and then when your sorted buy a motorbike helmet and hit the strip..

Hi guys wanting to know if you could help me?

I Want to buy a GTEC PRO for my R32 GTS-t but idont know which one would fit?

the GTEC PRO SS or GTEC PRO RR and whats the difference?????

Please help.

Cheers  

Daniel

Daniel,

I have a RR model GTech. I would strongly recommend this model over the SS. It will do all that the SS can do plus will handle data logging on the circuit.

The RR will record two hours worth of data at a logging rate of 20Hz which includes rpm, lateral & longitudinal gees & can then be downloaded to your PC. So it is a great data logger for a track day.

Also the RR will record quarter mile times, 0 - 100, acceleration & braking gees for when you want to practice launches, check the efficacy of engine mods or even measure your braking efforts.

I can't recommend these things highly enough.

Have a look at my photos thing on the left for some screen dumps of some laps around Wanneroo short circuit. (Gtech is on the windscreen) Unfortunately the installation wasn't quite right & the data is upside down (ie left is really right & braking is really acceleration). But you can see how the thing works.

You can overlay your laptimes & if you lend you Gtech to your mates you can compare the cars various strengths & weaknesses.

I got mine on Ebay & paid < $500.

Go get one, they are unreal.

:uh-huh: :uh-huh: :uh-huh:

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.

      The filter only filters down to a specific size. Add to that, the filter is AFTER the pump. So it means everything starts breaking your pump even if its being filtered out.

      Just like in being 14mm too small (296mm) makes it not fit, being 14mm too big (324mm) it also won't fit. You want to find the correct rotor.

      @GTSBoy Ok so that was the shops problem...they showed R33 rotors on R34 page and i did not know 296 do not fit(and are for R33) Yes i bought "kit" with rotors and pads. Pads are ok(i have GTT calipers front and rear). They have some 324mm but no 310mm. So i dont know if they would fit. I have 17inch LMGT4s So another question. Can i fit those in the rear or they are just "too" big for that?
