Does anyone use a scan tool like Autel Maxiscan to check and clear codes?

http://www.auteltech.com/ms609.htm

I've got the BT cable which is fine to use with my laptop, but it is not something I carry around with me. Since I am running the JBD and I occasionally get an SES light or check engine/limp mode when I am traveling. Thought having something like in this in the glovebox would be more convenient.

Anyone using something similar?

Truth be told, the lights are probably going to be nothing to worry about. JBD will mostly cause an SES or CEL as a result of rail pressure plausibility, which is basically saying that the JBD is pushing your car more than it can handle (if it does, dial the JBD down a notch or two..if you're running 100%, drop it to say...85%, and see if it continues to happen).

It's not going to be anything you'll need to address straight off, and you can just clear at home.

The JBD at 100% occassionally puts my car in limp mode, I never had an SES light from it, only limp mode. I've been running it dialed down (2 1/2 clicks) and the power delivery is noticable diminished by comparison, so I turned it back up to 100% and I'm willing to contend with the occassional limp mode, but want the ability to quickly and easily clear the code while on the fly while away from home.

Speaking of the few cars that report going into limp mode when the JBD is turned up to 100% vs those that NEVER experience any problems. I am wonding if it's the individual JBD's and not the car. I would love test this question by running someone else's JBD that does not put their car into limp when running at 100% to rule it out.

Mine used to put my car into limp, but you have to remember that I had the first incarnation of the JBD, so mine might be slightly different. Now, @ 100%, it doesn't do anything of the sort....the only thing I get now is an SES for gas pressure, and that's new since I got my DPF swapped out. I'm thinking the dealership made some minor modifications to that system to be more sensitive to the gas pressure...not sure, though.

For the record, my JBD hasn't put my car into limp for...well, a long, long time.

Interesting.... Did you just keep clearning it and eventually it just didn't happen anymore?

I wonder if the car eventually adapted to running at the higher rail pressure.

My guess is there is some adaptation, yes. There's another tune I've been using, too, that has done the same thing, but it seems that one is more variable. Sometimes I can run it at a higher setting (it's maxed setting, sometimes), without an error/limp, and other times I can't. I thought it had to do with ambient temps, but even at 60F, it would sometimes trigger limp.

That was my first thought too after the JBD triggered limp mode for the 1st time after I had already driven many miles/weeks at 100% and not experiecing the problem. The first time it happened was during a long drive when it was VERY hot and humid, but then it happened a couple of other times after during cooler weather to include yesterday when it was just 55+ degrees/low humidity. Limp reversed after shutting car off, cleared the high pressure pump code when I got home.

I am going to keep running it at 100%, clearing codes as necessary and see if the computer adapts.

BTW, car dyno'd Sat at 294 rwhp 2 1/2 clicks from 100%. Didn't get torque numbers since they didn't have the current software. Another d running the tune and intake came in at 328 rwhp

My initial runs with Terry put the car at 307, no torque numbers, but it sure seems more powerful now. I'll need to get it run again, and I really want to compare to the other 2 tunes I have. I'm spinning tires in 2nd gear, which I wasn't doing before.

Can't run my JBD more than 70-75%

[335dM]

And can't erase any code with my cable from Terry!

What do you mean you can't erase codes? Do you see the fault codes and when you try to erase it doesn't? Have you contacted Terry?

[Ron1n]

Mine works fine....what happens when you try to erase?

Have you gone through my walkthrough?

[335dM]

i have terry's tool scan that came with my jbd and i cant make it work at all! can this tool can be use along with a pc or only with cluster? Everytime i use it, the speed needle go hit the stopper and it bends! Not good!

To read engine codes try engine code MSD80 in that long list of options from the 2nd tab (individual control modules) in the opening screen.

The BT cable is not designed to operate with cars beyond 2009 (something that Mike failed to mention when I purchased the JBD ). BT stated they are working on an update but it won't be available for many months. Reading engine codes is about all you can do with it if you have a 2010/2011.

OMG so this means i cant use it at all? I mean not erasing codes from inside the car with Terry's kit? I dont have a pc since i'm on Mac

Please go back and re-read what I wrote regarding your ability to check engine codes. Yes you can erase them, the drawback being that the BT software is not current to your car.

Not sure what you mean be "not erasing codes from inside the car with Terry's kit?" Are you speaking of the CAN tool or BT diagnostic cable that you connect to your lap top.

[335dM]

I have the BMS can tool

[335dM]

Sorry for my poor english writing but what i meant is that every time i tried to use it, i couldnt erase any codes or if i wanted to read codes too, the speed needle would go hit the stopper.

[cssnms]

Okay then we are talking about two entirely different things. E-mail Terry I am sure he can help you get it squared away. He sometimes even responds at night. I opted for the Baverian Technic diagnostic cable (BT tool) instead of the CAN tool.

Thanks.
