Thread: OBD2 data logger/black box device...

Ok, the Ranger issue I have is getting more awkward. Dealer service team recommended replace rail, pump, injectors (aerated fuel returning to the tank off the rail) - got 2nd opinion with a local outfit that have a good rep and lo and behold, vehicle performs flawlessly. No real reason to replace the fuel delivery gear from what they can see - and beyond that without the fault occuring in front of them not a lot they can do... While that potentially saves $8K it doesn't fix the issue with it going into limp mode intermittently.

So I've been looking for an OBD2 data logging device to hang off the ODB2 port in the vehicle and basically record the last say 2 hours recording and overwriting over the oldest stuff. This is IF we get the fault again we can look at all of the info off the thing and try and zero down exactly which system and what parameter is getting out of whack to cause the fault code that trips the thing into limp mode.

Problem is there don't seem to be any devices out there that are compact, designed to hang off the OBD2 port semi-permanently and will go into sleep mode with the vehicle is turned off (OBD2 port stays live so a device that won't 'go to sleep' can flatten the battery...).

Used to see these a lot - Plusquip OBD11 Black Box Recorder (EQP-104)

which just plugs in and automatically records the values and you download and empty the devices memory regularly. But - can't seem to find one (only option for those I can find is Ebay which appears not to be an option for getting it to NZ).

Anyone know of anything else that will do this job? Don't really need the fault code reader as we are interested in the engine sensor data on the lead up to the check powertrain light illuminating and tripping the limp mode... Cheers
