Seems like a nice tool if it does what it says.

Think it will only work with the later OBD2 type systems.Cars with the diagnostic plug under the dash.
I have a OBD2 lead to RS232 interface plug which connects to a laptop, the software can be downloaded from the net free on purchase of the lead (£60).
This monitors what is going on with a vitual dashboard as part of the software. The applications i have are Ford EECV and late Jaguar whatever that system is.

On Board Diagnostics - a feature which monitors cat performance, engine misfire and other things which illuminates the MIL (Malfunction Indicator Light) if it sees a problem that would result in the vehicle exceeding legal emission figures.

The tools under discussion interrogate the CAN (Car Area Network) to give you access to the values being seen by the ECU - interesting but ultimately not actually very useful since you can't change the calibration...

Isn't CAN the latest protocol used in on board diagnostics? I'm not sure how many cars are using CAN at the moment, the RX-8 is one of the few.

Also KW2000, or RS432 connection is fed through on those not using CAN.

OBD2 was designed to be a standardised connector for interface into vehicle diagnostics, but whoever was regulating it wasn't strict enough and so manufacturers position the signals in the connector how they please.

The protocols basically used on these system are similar to the OBD2 standard, they were designed to be standardised but ended up being whatever the vm's wanted.

They're not complicated and as long as you know the commands for your ecu you can quite easily setup a little comms sw for your pc and diagnose the ecu.

I haven't look at the site the esp sw yet, but it sounds like it could be quite useful, provided you can aquire the correct cabling for your vehicle.

BTW after 1996 all cars were required to fit an OBD2 interface to the vehicles (mass production anyway).

It would be useful for me as I'll want to overlay lots of different lap times, compare entrance and exit speeds etc

Could it do this ??

Ermmm that lists at £499, a bit different to £60 for the lead and sofware

Yes but if you want to compare entrance/exit speeds and get a track map to do overlays... it does the job for a fraction of the cost of other stuff. It also allows you to hook up the car's systems to get other data as well.

I am not sure that a Caterham has the appropriate interface anyway!

AN AP22 would do a similar job at less money. Doesn't have the GPS positioning etc but the accelerometers will give you some indication of what the car is doing.
