Some interesting statistics

Recommended Posts

Had my car in for service this Monday and got some interesting statistics provided on paper when I picked it up. Apparently you can get a "Performance Information" report via the ECU. Rev. and Speed history listed below. Apart from that it mentioned that the best 0-100 km/h time was 6.5 seconds. 0-160 km/h was 12.6 seconds and top speed 264 km/h... Somewhat telling of the characteristics, V6 with supercharger and 6 speed gearbox cruises along well on the highway at moderate revs.

Coincidentally, I was just pulling the perf stats from mine today over the OBD port...

Time @ RPM
500-1500 5d:2h:28m:49.5s
1500-2500 2d:18h:6m:14.7s
2500-3500 1d:3h:13m:6.8s
3500-4500 2h:29m:22.0s
4500-5500 10m:55.1s
5500-6500 1m:30.0s
6500-7000 2.5s
7000+ .5s

 

Time @ Speed
0-30kmh 2d:14h:59m:33.1s
30-60kmh 1d:16h:50m:39.2s
60-90kmh 1d:40m:48.5s
90-120kmh 19h:13m:56.3s
120-150kmh 15h:13m:2.5s
150-180kmh 2h:47m:25.3s
180-210kmh 3m:37.4s
210+kmh 0s

It has a max recorded vehicle speed of 126mph, fastest 0-100kmh of 5.8s and seemingly no fastest 0-160kmh (0xFF is stored which means 'never'!).

Reminds me of a printout from a dealer servicing my daily driver Elise S2 111S in 2005.

They questioned the unusual tyre wear and assumed the ECU printout must be an error.  It listed a fastest 0-60mph of 4.7 (beating the lotus claimed 5.1) and had recorded 48 standing starts since the last service...

 

...I was also competing in sprints at the time. :)

 

My Evora spends a sad amount of time on cruise control at 52mph these days.

What do you need to pull these - presumably something more than just an OBD reader. I had mine at first service, but I'm sure it'd be somewhat more interesting reading now.

Yes you do need something, a laptop which can connect via wifi/bluetooth/cable to the OBD reader.

(Arguably it is also possible to do with an iPhone, but it's a pain the backside!)

 

Most (all?) bluetooth OBD plugs present themselves as a serial port to a computer, and you talk to them as you would a modem,

I've some crap PERL code to read all the 'mode-22 PIDs', these are where the enhanced performance related metrics are stored. Though it's not at all polished and only just about useful at this point in time. You're welcome to try it if you want.

Years ago in a previous life I spent some time at the McLaren factory when they were building the F1. They were starting to get some of the early cars back for servicing, including one from Germany. A chat with the service manager revealed some interesting driver behaviour. The ECU data revealed prolonged periods of 200 mph plus, usually early morning and late evening. Testing showed there was nothing wrong with the ECU so they contacted the owner.

Sure enough, his daily commute included several long stretches of Autobahn and yes, he regularly "used the full potential of the car" on his way to and from the office. Which was nice.

That would be Thomas Bscher, German banker and BPR F1 GTR Team owner. He bought the road F1 to replace his 911 Turbo and save a few minutes on his twice weekly commute to from Cologne to Frankfurt.
