I have done a search here and only found a couple of very minor references to the Autotap OBDII tool...


Does anyone out there have any experience, good or bad with it? Will it show injector balance rates? Thinking of buying one and want to know what others think of it.


Thanks,


John

I have one but haven't used it much. I'm not sure if it will do balance rates. The Autotap support people were pretty responsive to me with my pre-purchase questions. My only complaint, so far, is that the PC must be connected to the OBDII port for the software to be usable. That means that you must be sitting in the truck to set up the various screen configurations that you desire. Not very convenient.

I called B&B Electronics today (the manufacturer of Autotap) and talked to them about this. They said that Autotap scans the computer and should report on any parameter that the computer is tracking. They said that what is on their web site (what I believe Mackin is quoting) is kinda a "random collection of things" to give the customer an idea of the kind of things reported.


So, Ragtop
...the next time you have Autotap out (or anyone else out there), could you confirm this.


BTW, they did say that they have a 30 day return policy, so if I didn't like it for any reason, they would take it back no questions asked.

John,


I apologize. We have been packing to move and the Auto-Tap cable/module has been boxed and hiding. I do remember that there were only 4 injector pulse widths like Hoot stated earlier. I do have the software on my laptop but without the cable/module it is useless. Can't even browse through or set up different config screens for different test. The few things that I did with it (checked throttle position range) worked great.

Ragtop,


I have the Autotap also. Mine dosen't work anymore, recently discovered my cig lighter dosen't work either. IIRC that is a common fuse for the diagnostic port. If so I'll fix it this weekend and try it. I don't think it will tell you balance rates though unless you can do the math from pulse widths
Don't have a clue why/if the cig lighter fuse is blown I've never used it.
