I bought the Powertrain Only version

works great.....

 

yes I've been "shopping" for a scan tool of my own with a little more expandability. I've played with some of the "tool guy" scanners, but have found unless you spend at least 1K, they don't do enough to make me happy. Star scanners are still way high in price as well as old DRB's. The list of displayed items you listed looks really nice for the $$.

 

Ok, I gotcha.

Knowing that target info is definitely useful (and necessary for serious troubleshooting), but saying the gauges/monitors are "nothing more than eye candy" is not really true. You can still see if you're draining the rail or not because we know the psi should increase at to a certain point at WOT. If your pressure goes from 23k to 17k at WOT you know you have a problem. 99% of the rail pressure issues are related to modding, so IMO the gauges/monitors are very useful.

I don't really see a need to constantly monitor rail pressure though. Once your truck is setup and you know the pressures are good then nothing should really change. That's the major reason I went with the laptop scan tool instead of a rail only gauge.

 

good point Justin

so you gonna call them about the 2second update time or should I???

 

I'll call if I can remember sometime Monday!

 

However, having a guage monitored all the time can help you know in advance if something is going wrong. Like a leaking rail relief valve, cps cascade valve, leaking injector......... I know where you're coming from, but I prefer to have mine available at a glance.

 

...unless something else is causing a fuel de-rate. In that case you would see your "setpoint" is also at the lower reading pulling fuel back. Keep trying to convince me otherwise. I am open to new and exciting items for these trucks.....but so far IT'S EYE CANDY

 

Either way, you still see there IS a problem from the pressure drop. If your truck is defueling at WOT for no reason you DO have a problem.

If you think it's eye candy then that's fine, don't buy one. The fact is it is usefull for most of us to see how our mods affect rail pressure. Mark also showed that the enhanced version shows the rail pressure setpoint if you really needed to know it.

 

....and that certain "point" would be.........SETPOINT!

I know, I know...your done here. I'm a stupid dealer tech...would you expect any less??

.....and to be honest with the way downloaders, piggy back chips affect the data it may all be hocus pocus I'd be looking at anyway. If I suspect a downloader I'll flash the ECM so it is on the same page as I am.

 

I understand what you're saying, and I appreciate the info you posted because I didn't even know there was a setpoint until you mentioned it.

Like I said before, I agree the setpoint would absolutely be needed for serious troubleshooting. However, not knowing the setpoint doesn't automatically make the gauge reading useless. It's no secret, we know the max rail pressure under WOT should typically be around 24-25k (give or take). If you add a bunch of mods and suddenly it starts going down to 17k at WOT, then you know you have an issue with draining the rail. The gauge will tell you this and that's why it's not just "eye candy" for most of us.
