In-car OBDii data

[GTT 280]

Hi all,

Can anybody advise on the best solution (wireless/bluetooth if possible) for recording streaming data to a laptop for after-drive analysis? I beleive you can access the CAN data too?

I purchased the mOByDic package a year or so ago, and to be honest, it's a load of cr4p, it never works 95% of the time, and is very cumbersome.

I'm looking at velcroing my laptop in the back of the car (no rear seats) so wireless would be ideal, with the added benefit of not having wires int he way of your pedals.

Any advice, expert knowledge, and hands on experience of recommended products would be great.

Happy to spend C. £150

Cheers,
K.

I just got the ScanGauge II, picking it up tomorrow.

I just want to do a bit of milage monitoring and keep track of compressor pressure and air intake temperature as measured by the Mini. I suspect I drove around with a broken pressure sensor untill it broke down complete. Maybe to monitor the knock sensor indication to see if knocking occurs but I doubt if the ODB data is fast enough to see that.

Hi,

What readout options are available on that? does it cover all OBDii data?

I do like the idea of dumping everything to hard drive and analysing after the drive/race

But now also like the idea of in car real-time monitoring of key attributes like temps, pressures etc. as hopefully offered by Scan Gauge II.

So looks like two solutions are being considered now

........desperate for further information

What software are you using with Mobydic? Are you using Digomoto? if so, what version?

I use an ELM327 with Digimoto 4 for ODB II but still its only ODB so not amazingly fast and not many features.

[GTT 280]

Yes, digitmoto 4, but not ELM, i use the other protocol. It's a bit slow, yes. And i can only ever get it to connect 5% of the time. Not impressed at all really.

Hence a request thrown out for info on bluetooth OBDii streaming data solutions... anyone???

Cheers,

This ones is suppose to be good but the bluetooth option is quite large. OE-Level Coverage (Enhanced Interfaces) Far more powerful than ODBII aswell if you use the BMW extention version Almost as good as EDIABAS....

Remember reading the obd port will not give you true realtime data.

To be acurate enough to study later you should use a proper data logger.

Have a look at Innovate Motorsports Wideband Air/Fuel Ratio Tuning

Im running 4 egt sensors, wideband, boost, intake temp, throttle pos, revs and just about anything the engine is doing.

i spoke with Roland on this very subject. and the monitoring on the scanguage depends on how many guages you are using, ie yu can use up to 4 at any one time. But if you choose one it is 4 times faster refresh rate, but i have forgotten what he said now, i'm sure it was once every second if using one sensor and 4 seconds if using all 4, oh i can't remember now, but yes faster if losing less sensors. Worth while though, i love the max figures you can see for Revs, mine was showin as scarily high at 7400 rpm the other day, that was the max for the last 3 months, oops.

[Berthil]

It's one every second if one has 5 gauges selected.

PLX Devices Inc. - A Silicon Valley California Company has DM200/DM100 which also reads OBD data.
Also has very nice LED gauges but not dimmable at night and EGT.

For realtime data I am going the Innovate route (Innovate Motorsports Wideband Air/Fuel Ratio Tuning), I'm getting a LMA-3 with 2 XD-16 displays to measure compressor pressure and exhaust gas temperature (EGT, above 950 celcius your cilinderhead gets destroyed). Expensive but very nice and customisable. Maybe I'm getting the wideband LC-1 too if I change more to my engine but for now the EGT is enough to detect too lean running. The LMA-3 is a also data logger with G-forces to analyze my laps on the Nordschleife

Love these but very pricey

[GTT 280]

I would like a solution that provides me with:

1) The ability to monitor real time values for the 4 most serious factors for an engine to get destroyed, such as oil, temp, etc. etc.??? This would be on a digital readout, possibly changeable between several data types.

2) The ability to download absolutely everything from the vehicle as a streaming data dump to be analysed in detail after the drive. I'd also like this to be able to interface with the car when stationary so I could check things. This would all be on a laptop.

Does anybody know of such a thing (probably have to be two separate products? used exclusively) - I haven't really had chance to look online at your recommendations yet ?

Not keen on the DashDAQ - looks a bit 'jack-of-all-trades' to me, and doesn't really indulge in anything particular.

Cheers,
K.

I thought the msd dashawk was the answer untill you realise they dont list it as being compatible.

[Berthil]

OBD won't give you oil temperature in the Mini. You won't get data logging for 150 pounds either or you must drive around with a laptop hooked up to the OBD of the Mini.

I'm going to buy the Innovate stuff. I hear it's good quality and it's scalable/programmable.

I've spend over 300 euro's on different gauges that didn't bring what I exepected or broke down (don't buy Cyberdyne).

[Lucky Dave]

I have the innovate kit and im very happy with it.

The digital dials are very nice and can be programmed to display any of the chanels you are monitoring.
