knowing how our beloved monty throw a lot of SES lights, I am quite leary on putting in any plug-in OBD on its port....LOL

Haven't ever had a problem using mine. Sure beats paying a mechanic $20 to clear a code whenever the wifey forgets to put her gas cap back on. And the peace of mind knowing if an SES is critical when you're out on the road.

I haven't had any problems either. I do however only plug/unplug it with the vehicle off.

And the peace of mind knowing if an SES is critical when you're out on the road. I'm with DC on this. I've been on enough week+ long vacations in the middle of nowhere and had a CEL pop up that having the ability to - at the least - read codes is very valuable. Some stuff you can ignore - what DC was alluding to - but having something like a forward O2 sensor go and then continue to drive for a 1000 miles can cause very expensive damage to CAT(s). I'd prefer to know and be able to replace the O2 or whatever BEFORE I cause $3000 in damage. Something to know, BTW, with OBD software scanners like Torque and DashCommand. I'm not referring to code readers that do a scan and then stop. This is for apps that continually scan for display - real time monitoring. These tools poll a lot of pids, and they poll repeatedly in very short sequence. This puts a load on the ECM/PCM. This polling can overload the ECM/PCM causing the ECM/PCM to not be able to process normal operational data as quickly as it should and this can affect the performance of the vehicle. I haven't run across this with my '03 but I rarely run my OBD monitoring/diagnostic tools on that vehicle. On both the '97 equipped ECMs I've had problems running the new app and PC software. While I haven't tested a '98, I do have ECMs for both the Montero and Montero Sport from '96 through '99 and with the exception of the new PCM released late '99, the CPUs are the same. Given that it's reasonable to assume that those ECM equipped vehicles might see the same issues. This is, BTW, a documented issue that affects some other make vehicles. So, this isn't specific to Mitsu. There are 'work arounds' of sorts. Decreasing the number of PIDs polled to the bare minimum is the first and foremost. Changing polling timing/frequency is the next thing. The first is usually the easiest and is usually recommended by the vendor. I've had varying levels of success with the second. Some applications don't allow much room to tweak there. The other issue is that its difficult to diagnose some issues if you have to limit the polling frequency and/or timing to, say, once a second or two instead of once every 1/4 or 1/2 a second. Same for the first, its difficult for general diagnosis if you have to limit yourself to half a dozen PIDs - doesn't give you the full picture. If you see a strange drop in performance and/or gas mileage ONLY when using whatever OBD application/hardware this is probably - almost certainly - the problem. Otherwise, there shouldn't be any worry about using the OBD plug and applications. There is virtually nothing you can do that could potentially damage something. If you're lucky enough to have a MUT, on the other hand, that's a different story. Edward

They are nifty little devices. I'll have to pay closer attention to see if performance diminishes while it's monitoring.
