yes after some more checking i decide to take a chance i bought the elm37 usb obii obd3 can-bus version 1.5a the diffences in the 1.4 and the 1.5a is :
Between the USB models, there should be little difference between the 1.4 and 1.5 other than obvious cosmetics. With the bluetooth adapters, the 1.5 hardware adressed reliability issues with the 1.4 firmware and The 1.5a is built a little nicer and offers a longer cable to your computer
i pay about 33.00 with shipping my comes with software ( which iam sure its freeware software that comes with it) i pay more for the longer cables so we will see how well this works i know i cant do ALL the tests out there with this but hopefully it will help with most things
irankzz – where can u buy the logging software at?
thanks
