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..

  • 4 weeks later...

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:

    • I had 3 counts over the last couple of weeks once where i got stranded at a jdm paint yard booking in some work. 2nd time was moving the car into the drive way for the inspection and the 3rd was during the inspection for the co2 leak test. Fix: 1st, car off for a hour and half disconnected battery 10mins 4th try car started 2nd, 5th try started 3rd, countless time starting disconnected battery dude was under the hood listening to the starting sequence fuel pump ect.   
    • This. As for your options - I suggest remote mounting the Nissan sensor further away on a length of steel tube. That tube to have a loop in it to handle vibration, etc etc. You will need to either put a tee and a bleed fitting near the sensor, or crack the fitting at the sensor to bleed it full of oil when you first set it up, otherwise you won't get the line filled. But this is a small problem. Just needs enough access to get it done.
    • The time is always correct. Only the date is wrong. It currently thinks it is January 19. Tomorrow it will say it is January 20. The date and time are ( should be ! ) retrieved from the GPS navigation system.
    • Buy yourself a set of easy outs. See if they will get a good bite in and unthread it.   Very very lucky the whole sender didn't let go while on the track and cost you a motor!
    • Well GTSBoy, prepare yourself further. I did a track day with 1/2 a day prep on Friday, inpromptu. The good news is that I got home, and didn't drive the car into a wall. Everything seemed mostly okay. The car was even a little faster than it was last time. I also got to get some good datalog data too. I also noticed a tiny bit of knock which was (luckily?) recorded. All I know is the knock sensors got recalibrated.... and are notorious for false knock. So I don't know if they are too sensitive, not sensitive enough... or some other third option. But I reduced timing anyway. It wasn't every pull through the session either. Think along the lines of -1 degree of timing for say, three instances while at the top of 4th in a 20 minute all-hot-lap session. Unfortunately at the end of session 2... I noticed a little oil. I borrowed some jack stands and a jack and took a look under there, but as is often the case, messing around with it kinda half cleaned it up, it was not conclusive where it was coming from. I decided to give it another go and see how it was. The amount of oil was maybe one/two small drops. I did another 20 minute session and car went well, and I was just starting to get into it and not be terrified of driving on track. I pulled over and checked in the pits and saw this: This is where I called it, packed up and went home as I live ~20 min from the track with a VERY VERY CLOSE EYE on Oil Pressure on the way home. The volume wasn't much but you never know. I checked it today when I had my own space/tools/time to find out what was going on, wanted to clean it up, run the car and see if any of the fittings from around the oil filter were causing it. I have like.. 5 fittings there, so I suspected one was (hopefully?) the culprit. It became immediately apparent as soon as I looked around more closely. 795d266d-a034-4b8c-89c9-d83860f5d00a.mp4       This is the R34 GTT oil sender connected via an adapter to an oil cooler block I have installed which runs AN lines to my cooler (and back). There's also an oil temp sensor on top.  Just after that video, I attempted to unthread the sensor to see if it's loose/worn and it disintegrated in my hand. So yes. I am glad I noticed that oil because it would appear that complete and utter catastrophic engine failure was about 1 second of engine runtime away. I did try to drill the fitting out, and only succeeded in drilling the middle hole much larger and now there's a... smooth hole in there with what looks like a damn sleeve still incredibly tight in there. Not really sure how to proceed from here. My options: 1) Find someone who can remove the stuck fitting, and use a steel adapter so it won't fatigue? (Female BSPT for the R34 sender to 1/8NPT male - HARD to find). IF it isn't possible to remove - Buy a new block ($320) and have someone tap a new 1/8NPT in the top of it ($????) and hope the steel adapter works better. 2) Buy a new block and give up on the OEM pressure sender for the dash entirely, and use the supplied 1/8 NPT for the oil temp sender. Having the oil pressure read 0 in the dash with the warning lamp will give me a lot of anxiety driving around. I do have the actual GM sensor/sender working, but it needs OBD2 as a gauge. If I'm datalogging I don't actually have a readout of what the gauge is currently displaying. 3) Other? Find a new location for the OEM sender? Though I don't know of anywhere that will work. I also don't know if a steel adapter is actually functionally smart here. It's clearly leveraged itself through vibration of the motor and snapped in half. This doesn't seem like a setup a smart person would replicate given the weight of the OEM sender. Still pretty happy being lucky for once and seeing this at the absolute last moment before bye bye motor in a big way, even if an adapter is apparently 6 weeks+ delivery and I have no way to free the current stuck/potentially destroyed threads in the current oil block.
