Best way to Get G/S readings on LCR?

[welchy]

What is the optimum speed and gear to get good g/s readings in an LCR, and how long should you stay at that speed if that makes sense?

-Say if i log the readings travelling in 4th gear at would revs would usually give iptimum g/s of should i stay at?

Im new to this logging stuff and just trying to get my head around it, just tried in second at 5430 and got 134g/s which i know is well short of the bhp i should be running at!

Cheers

Torque or Liquid Gauge.

Can't edit my message for some reason, Peak G/S is around 5300rpm
I did a run in 2nd and 3rd

- VCDS Block 002
- 4th Gear if the road/conditions permit (3rd gear if not)
- 2000rpm - Redline
- Foot flat to the floor all the way through
- Once you hit the Redline, it's all done, ease off and brake!

Log 3rd of 4th gear, 1500rpm to redline then review. That will be good enough.

I tend to do 2 blocks at a time max to get good sample rate.

 

[welchy]

So, first try it in 3rd gear and set a marker on VCDS and log, then put it in 4th gear select a marker and log again. Both times starting from 2,000 RPM and going all the way to redline yeh?

Cheers guys

No, either 3rd or 4th. Ideally you would always do it in 4th as the rev range takes longer to cover and more data is extracted by the ECU however a 4th gear run will take you to a huge amount of speed so 3rd gear is an alternative, not as good but still ok for this purpose.

- Connect cable to laptop
- Connect other end of cable to OBD port
- Start up VCDS
- Click 'select control module'
- Click '01 engine'
- Click 'Meas. Blocks 08.'
- Type in '002' and then click 'go'
- At the bottom right of the screen click 'log'
- Now when you're at 2000rpm, hold it and click 'start'
- Now floor it until redline
- Lay off and pull over, click 'stop'
- Click 'done & go back'
- The log will now be saved in the Logs folder within the VCDS directory wherever you saved it on you laptop.

If you're doing this on your own, a good/safe tip is to have the mouse cursor hovered over the 'start' button. This way when you are driving you can just hit the left-click button and it'll start. Do this again when you hit redline and it'll stop, pull over and click 'done and go back'.

Cheers pal, i'll do it back home in devon as im in birmingham at the moment, and i dont think there is anywhere you could make that speed safely in/near the city!!!!

Pulled 160 g/s on average, does that sound like enough from a standard 210 LCR?atleast i think its a 210!lol

 

[JamJay]

160g/s equates to about 200 - 205bhp. Doesn't sound too bad but could be improved.

Things like servicing, heat soak, small boost leak etc can affect things like this. How does the car drive?

 

[welchy]

The car has been serviced recently, running good oil, new sparks, pipercross panel filter, 007P, and silicone TIP. Think i could probably get better readings, maybe another 3-4g/s if i had a better run. Ran VCDS lite vagcom, not the registered version, I have no fault codes, but still unsure if there is a small boost leak.. Any sure fire way to tell, what to do etc? Wasn't doing it on a good private runway, tree's kept coming up on it and some cars were driving on it for some reason so had to back off!lol

cheers pal

Got some logs on this RR

No worries. I know it's hard bu you need to hit the limiter really to get the max g/s reading . Boost leaks are hard to find but they usually come with symptoms such as hesitation.

Hi mate, are you using the standard airbox or open cone filter? If you've got the standard set-up it might be restricting the airflow. I run a few logs last week and saw 172-176 g/s on my standard 210 lcr with a green cotton open cone filter, haven't got any logs with standard airbox though, just a thought.

 

[welchy]

Yeh its a standard airbox in there at the moment. The car is feeling hesitant at times so im tempted to account these possibilities to a boost leak. Not sure where the hell to start, is there a process you can do of checking through etc?does the vacuum hose on the servo often leak and cause problems?

EDIT:

Im struggling to work out if the car is hesitating as it has always been like this, pros since i bought it in July. When some suggestions pop up il have a gander for some leaks, am i just listening out for noise?
