I also don't trust the scan gauge and the like because it is just telling you what the computer sees and as we know it can be flawed.
just because you didn't have a problem with heat doesn't mean it's BS All a gauge does is tell you when to take your foot off the floor, mine used to boil over after ripping around in the sand for more than half an hour. a big cooler helped keep the temps down and the gauge helped me to know when i was pushing it too hard.a stock XJ should never have a trans temp issue, it BS!
Ahhh!! I forgot about my wideband. But for a modified engine (stroker, sc, turbo, doesn't really apply to usual bolt ons) a wideband is a must., save you money for a wide band
Trans Temp for me!
Like many others, transmission temp and a ScanGauge.
I have have one ScanGauge and move it from the XJ to the motor home, as needed.
Where did you get that pod? I think you have a 97+ judging by the tweeter.
Which is the one you have? I like the fact that they can be transplanted. I have a 97 Cat. Diesel pusher, a 02 Ford Diesel 7.3 van 4x4, 2 XJ's 95 & 99 and would like to keep the scan in the one I'm driving! Though my van has all the Autometer gauges I added like boost, tach, EGT, volt, trans temp, water temp, oil pressure, even a clock it's nice to see fuel economy as well. Unlike others the more knowledge and precise readings you can get the better. They call those lights warning lights IDIOT lights for a reason, by the time they come on it could be TOO late. I feel some of the factory gauges operate the same way, like the water temp gauge in XJ's being so unreliable! I'd like to have 3 of everything if it is going to keep my harmful temps down! I saw on some sites they can be had for around $150.00, if so I paid a lot more in gauges and feel this was a better way to go. Does it get plugged in directly to the OBD port or in line on the comp.??
i looked into scanguages website. it looks like we need one for obd2 & a different one for the cat diesels. i have a 2001 freightliner fl112 toterhome with a cat c-12 & would love to have a scanguage D for it. i'll be ordering the pair of them this week.
