I just got my new Juice/Attitude Saturday morning, installed by lunch, playing around on level 1 for an hour or so, then level 2. Nothing higher yet. Played around with the low boost fueling settings, currently on 4. Started with defueling on all locked shifts Saturday, but after reading some of the posts here, decided to switch to defueling only 4-5.

Problem 1: 1 time on Saturday and twice today (Sunday) I have had "crank no start" problems. Both times after turning the key off for 20 seconds or so it cranked with no further problems and no service lights at any time. I've seen posts like this about Juice bugs that were fixed in updates, but this is a brand new unit from John Kennedy.

Problem 2: I reconfigured the display today, just trying different things. I wasn't initially too concerned about monitoring "trans slip" only running up to L2 and my truck is fairly low mileage (less than 20k) and has not been beat hard at all. However, any time I'm accelerating even a little it's showing at least a few % points of "slip". Harder acceleration (not floored) will yield number up to 50%+. Is this normal? Is my TC failing to lock properly?

Problem 3: The docs are pretty vague on some things. For instance, what is "Load"? What do the "% slip" numbers indicate? Clearly lower is better, but exactly what does it mean? These things should be in the manual IMO...

I'll be calling John and/or someone at Edge tomorrow, just thought I would see what I could learn here tonight...Edited by: BadDog

Mine wouldnt start either. But I bent 2 of the pins putting it on. It sounds like (and I could be wrong) one or more of the pins arent making constant contact.

Try removing and re-inserting the plugs and check all the pins.

Mine does the slip % thing too. I think its normal.

Try running 0 and looking at slip. Its still there.

I would not run 4 on low boost (jmo). It really soots up the oil quick.

Be careful getting the tranny used to the juice. Mine slammed hard because it wasnt quite adapted.

Also turn the key and give it a 3 count before cranking. It takes the juice a sec to turn on.

i had this trouble 3 times, only when i adjust power levels and then shut down motor. the last one was on the dyno at jannetty's adjusting settings for diff. runs.Edited by: RUMAXED

I have had exactly the same situation happen three times. Twice it set DTC0335 code in ECM. This code is "no signal from CKP sensor". This sensor indicates the crankshaft position and speed. Turned key off and Juice powered down. Turn key on again and it starts. Have had the Juice installed for one week. Never happenned before the installation. Looks to me like a Juice initialization problem. Once running, it works perfectly (even in the rain with wipers on!). Will keep an eye on it for a month or so to see which way it takes us.Edited by: OC_DMAX

The high % of slip that you see is normal when the TC is NOT locked up. Ideally you should never see any slip in OD, but usually in the lower gears. With the Tow/Haul feature enabled the TC will be more likely to lock in lower gears, and you should see zero slip when it does.


As for the load % I really don't understand it. I have seen as high as 30% at cold idle, and then like 10% at warm idle. It will hit 100% pretty quick when I goose the throttle even while in "turbo lag". I'm guessing that a full explanation of it could get pretty long winded. --SS

Problem Child: Wouldn't bent pins cause a consistent no start? It started fine probably 10 times for each "no start". Still, I'll check it tomorrow. I also tried running zero, actually, that's what I had set it to after the suspicious readings but it didn't seem to make much difference.


Rumaxed: That could be it, I have been fooling around with it a lot in the last 2 days.


OC_Dmax: Likewise, mine has never failed to crank before this weekend. Based on other posts, I expected it to take a few more turns, but I didn’t expect no-start problems.


Slayer: I just tried the tow/haul and it did dramatically reduce the slip readings, but they are still there. I guess I just expected it to read no slip anytime the TC was locked, which I expected to be more often. I've also seen it reporting slip at over 60 mph in OD. I also pause before cranking just from habit, I often drive EFI gassers too...

I have had the same problem with my juice it would not start unless I would disconect and reconnect the juice then it would start but this does not always happen only sometimes.

BadDog,


Keep us up to date on what you find out.


With respect to the torque converter locking, you can display on the attitude screen the state of the torque converter (locked or not locked). You may want to display this along with the % slip. Once it is locked, the slip should be zero (though as I drive down the freeway, I notice that it toggles to 0.6% about every 20 secs.)

BadDog,


Had my Edge and attitude on for a couple of months now. I've had the crank no start problems too. All occurred after long drives, 2 or more hours on the interstate and after a quick stop she wouldn't start. after checking the connections she started without any more problems. please post what ya find out bout this.


As for the slip shown on the attitude I belive I read in a post that it is the % difference between the input shaft and the output shaft on the trans. I've noticed on mine that the TC locks up at 50 mph. the Attitude will display when the TC locks up shouldn't show slip, atleast mine doesn't except for the 0.6% it shows sometimes when cruising. My thoughts are that this is from slack in the drivetrain. Anyone Know for sure?


Just my $.02

Well, this is interesting. I've seen an odd "crank no start" mentioned a few times in the past, but nothing like this. Now it seems like many are having it. I wonder if the latest crop of Attitude/Juice setups have another "bug" to be corrected. I'll post up whatever John and/or Edge have to say about this.

Biggest thing is I'm glad the slip is not indicating a preexisting (pre Juice that is) problem that I didn't notice and the Juice just brought out and displayed.Edited by: BadDog

Bad dog you are correct bent pins means no start at all.

I was telling you that maybe you have pins that arent touching "ALL THE TIME". Kind of a intermittent contact.

I have seent this happen thousands of times in the electronics/computer industry.

One of the latest was a server that would not boot after a shutdown. I pulled the ram and cpu and re-inserted them. Everything was fine from that point on.

The pins arent touching all the ime or arent touching enough.


Thats just my guess.

I have the hot OJ and have NOT had a problem starting up.Edited by: problemchild

Just talked to John and Edge over the last few hours. Looks like I'm going to be getting a new box in the next few days due to the "no start" issue. One other thing Edge (Matt? <st1:place>Erin</st1:place> was out) suggested was opening the door to break the acc circuit when trying a second attempt at cranking.

Apparently the load display is largely pointless for our use. And trans slip display is only slightly useful at best except during TC lock (as was already pointed out here). It was suggested that a more useful display is gear selected with TC lock indicator (little star). With lock indicated, slip should be less than 1% if I understood correctly. I'll be trying this to see what I get.

Problem Child: Thanks for the clarification. I've reseated the plugs but have not driven it again so I don't know if it will matter. Edge seems to think it may be a glitch in the box so they are sending another. If I notice another "no start" before replacing the box in a few days I'll post up.

Over all the response from John and from Edge are exactly what I expected after all the great reviews I've seen for other customers on the forums. Just my luck that I would be "one of the few" to have a problem. &lt;sigh&gt; :D

Had to return mine due to shutting off after start up. Ran fine for one whole day; had the day off so I was playing, the next morning let the truck warm up and then tried to drive off and it shut off. Truck readout was saying "battery not charging", it would idle but not take any fuel. Volt meter at 14. Started right back up and did the same thing. Unpluged Edge and all was fine. Should be getting replacement any day.

BadDog,


My Juice was probably built along side yours, since I have had mine for two weeks or so and it was also purchased from John. I am on business travel right now, but I believe the manufacture date was mid-January (sticker on side of hardware). Let me know if the new box fixes your problems. It will be interesting if this is a part tolerance or defective part problem related to a particular manufacturing build.


If mine does this no start thing another time, I will be making some phone calls also.





Thanks,

Had the no start problem with mine at first, could just jiggle the wires at connection &amp; would start. Havn't had problem any more. I think the wire get loose when you bend the connection to plug them in. Just make sure all the wires stay setted.

Ok, I said I would update, so here it is...


Edge sent me the replacement, but I have not yet installed it. After the first couple of days, there have been no more problems with the "crank no start". I have no idea what changed, but it's running great.


The only thing I notice now is that even though it's set to only defuel on 4-5, I can distinctly feel defueling for shifts when I get on it a bit. I may swap on the replacement this week end just to see what difference it makes.

I think I heard somewhere that even if you have the "Attitude" set for no defueling...the truck's PCM receives info from the transmission that indicates things are starting to get out of hand....so the truck's PCM defuels. Mine used to do the same thing. All I did was upgrade my transmission/converter and the defueling is gone. The Attitude is the same. Hope this helps.

I think I'm glad I got the banks stinger kit instead of the juice based on the rampant complaints it gets for, what I consider, a lot of little problems that shouldn't exsist. I dont care about who has the most hp and tq if it is constantly causing little, but annoying problems. I've had not one problem with the banks kit, and love the extra oomph for towing.
