If this is whats causing greif here then I'd recommend trying a different (preferably not a chinese!) type of OBD tool. In these instances you get an 'ecu not found' or 'unable to establish communications' etc type error, despite having retreived the ecu details. I use a much more modern (genuine, not chinese!) version of the tool by the same developer as the kwp2000 for remapping cars, and I'm aware of a bug in the way security keys are handled for these ecu's which gives the appearance of being able to communicate with the ECU (get ID etc) but will not be able to authorise itself for access for reading/memory writing etc. Otherwise it should like it could be a duff KWP2000. I would also try the BMW program on the KWP as well as the Rover one to see if it can read it that way. You need to remember that the battery voltage must be kept well up, so you will need a charger or booster on the battery whilst reading or writing to the ECU, something that can deliver 20-30 amps whilst you have the ignition on. Or is just not meant to be Hmm! As I recall you have a diesel, so it should be able to read the ECU map from the DDE4.0 (EDC15C4) system with no problem. Result i thought!! However i then clicked the Read button and the app said something like 'waking ecu please wait' but would then return an error message of 'Internal Hardware Error' I've tried it repeatedly including changing the Speed from Fast to Slow but to no avail. It does work with Windows 7 but only the 32bit version, I have configured my laptop as a dual boot (64 & 32bit) just to support KWP2000 and Digimoto. ![]() Kwp2000 usb to serial driver drivers#So with those installed i tried to update the drivers for the 'USB to Serial device' that appeared when i plugged in the KWP2000+ box, however it didn't. Cheers for the replies i actually remembered my netbook was running xp so i installed the drivers on that fired up the application and bingo no 'Kick Not Found!' Error message So i then went out and connected it up to the car hit the data button, and it read back some info from the ECU displayed 3 lines of codes.

Kwp2000 usb to serial driver install#You can install the 32bit version beside the 64bit (make sure to put on different partition) and then you will have both and it will just work fine. Kwp2000 usb to serial driver license#I recommend to download the same version of Win7 what you have but only in 32bit and install then use your license key. You can try in virtual XP (free for Windows 7 professional and ultimate just need to download from Microsoft) but I doubt that it will work as it is on 64bit base too. Kwp2000 usb to serial driver driver#But these are both last ditch desperate efforts I fear because I suspect the driver has not been updated for Windows 7.Īny of these 'old' tweak tools are not working in 64bit environment. Kwp2000 usb to serial driver software#I don't know the software but if there is a part you can exit and launch, you could try running that part as Administrator (right click, run as administrator) Failing that, you could try running that part in a compatibility mode (right click and select properties to edit) and as administrator. The VM needs to communicate with Windows 7, and then Windows 7 with your KWP2000. ![]() You're right that its a software problem but your solution probably won't work. ![]() So after a bit of Googling i found a site that recommended downloading the drivers directly from the FDTI site itself () and modifying the.inf files to include the HardwareId's of the KWP2000+ device that's been found. I've got hold of one of those KWP2000+ devices off ebay with the aim to read my ECU and get the map tweaked My laptop is running 64bit Windows 7 On the disk came some new drivers for the FDTI chipset the KWP runs (CDM20814_Setup.exe) So with those installed i tried to update the drivers for the 'USB to Serial device' that appeared when i plugged in the KWP2000+ box, however it didn't result in any success.
