Backdown % Juice with Attitde

[JSnider]

I have a 05 with the Juice Attitude on it. Tonight I was playing with the Attitude monitor and my highest backdown recorded was 17%. Have any of you seen this high of a percentage? Until tonight the highest I have seen is around 3%. Could something be wrong with my edge box or my truck. Any input would be appreciated.

thanks, Jeff

Just depends on what kind of playing you were doing. If the max boost or max EGTs settings were exceded while you had your foot on the floor, it is suppose to backdown enough to compensate.



Ocassionally I decide to kick things up on my setup to play and forget about the backdown settings. I have seen over 50% backdown a couple of times, I don't think it can compensate fast as the II SPS66 turbo spools up .



I will add another comment. I believe that the backdown percentage is only telling what additional timing/duration that the Juice can supply at the selected level. In other words it cannot back down any stock fueling, timing or duration, just what the Juice adds. Clear as mudd now .

I rearely see EGT's over 1200* so that's where I set my "max EGT". Forgot about that yesterday and went over 1200*. Backdown was at 100%. Couldn't figure out why the hill seemed bigger than usual until I saw that. Fixed the "problem" by upping max point to 1250*.

whats if any is your max trans/clutch slippage? or can it do that with the manuals?

That would be clutch slippage

42%. I nailed the throttle with 6K trailer in tow 'cause some #@$@# on the freeway ticked me off. Thought the truck just stumbled until I looked at the records. Was on Level 3-3 at the time. Never towed on level 3 before and I guess I won't be doing it anymore.



I kinda have a hard time believing the slippage 'cause my rpms don't change with 3-4% showing. Lots of chatter here about it being just some programming thing. The situation above is the only time I think it really might have slipped. Not sure though if it really did or not, it was dark out and I was merging off the freeway(trying to) so I really wasn't paying attention to the gauges.

Ok I have to put in my . 02 on the Edge monitoring of transmission and boost. I like the Juice/Attitude both standard and Hot versions. The power delivery has been consistent and smooth at all settings for me. But the monitoring of boost is a joke. It looks like they monitor the ECM after it has been fooled, by the Juice. I have found that the Attitude will not go over about 36psi no matter what the real boost psi is. I can see 46psi on the Autometer and 36psi on the Attitude at the same time. The Attitude is accurate up to about 30psi and then BS. The MAP is limited to around 40psi max reading, so I dont really understand how the MAX boost setting could really be used accurately. Now on the to transmission monitoring. After two Juice and two Attitude modules from Edge they finally figured out that since I had my Pinion Factor reprogrammed by the dealer for the 315s that their Attitude could not accurately monitor lockup or slip or defuel on slip. I have seen slip up to 5% after clearing the records and driving 3 blocks to the store never getting out of 2nd gear. OK rant over.



I have full set of external gauges so I really dont care about the short comings of the Attitude monitor and the Transmission is close to bullet proof now so transmission slip doesnt happen. But it is irritating that they dont work as expected. OK, OK now rant is over.

Um, my records say 100% backdown and, get ready for this, 5018% slip

 

[JSnider]

Thanks for the input guys. I forgot all about the max boost setting. I must have changed it on accident the other day while I was adjusting my max egt temperature. For some reason my attitude monitor reset the other day and went back to the default settings. It would also ask my if I understand Edges agreement, just like I just installed it? At least I have one problem solved.



thanks again Jeff

 

[bzingre]

I've seen the 5018% slip too. I have no idea what that's about. Anybody know about this?

 

[BErmoyan]

bzingre,

That's weird that you got the 5018% slip too, espescially having a stick. I really havent felt any slip, I dunno, I'm sure the torque converter will give up eventually, but I think a clutch should hold up much better. Anyone else please post if you have any input

 

[Bob4x4]

If you have enough torque the clutch will slip... ... ... I have played with many in the old 12v.

reason i said trans/clutch was because i wasn't sure if he had a manual or an auto

 

[DLegate]

I have also seen 5018% but my truck is lifted with 325/65/18's so I thought that might be throwing off the computer

Doesnt the attitude allow you to set your tire size as well? I know thats primarily so you can see true speed, but you would also think they would use that as a correction factor for determining slip/lockup... . am i being too logical?

 

[Matt400]

Thats an interesting statement, of course the hole idea of the Attitude is to also have a full set of "functioning" gauges. Geeze! kinda like the Outlook showing you fooled rail pressure, who cares to see that?



I don't understand then how the boost backdown function could work.

 

[JVolpe]

Ok, someone pointed out on another site that the new Edge Juice/Attitude manual has the following statement:



NOTE: If you re-calibrate your tire size at a Dodge dealership, the

transmission slip backdown feature will not function.



I have not talked lately with anyone at Edge and really did not see the boost issue for a while. With the new SPS66 it is pretty evident. I have seen 46-48psi on the Autometer and as quick as I could look at the Attitude with my foot still planted firmly on the floor, the Attitude would show 35-36psi. I have been convinced by the electrical engineers on sites that the stock MAP sensor and computer can not really be accurate over 40psi anyway. It does not really matter to me, because I have mods to handle the power I am making and standalone gauges to monitor whats really going on. Just dont want anyone to get a false since of security with the wrong combination.

 

[Devan Manis]

well if there ever is a need for you to defuel to or below 35 psi the edge will do all its capable of. just for fun why don't you try it i would like to know how much it could defuel with your mods... . im guessing 40psi.

 

[JVolpe]

I have seen all kinds of backdown %. With the Attitude max boost at 36psi and I turn up the boxes and put the throttle down I will see 50+% backdown. My point is that you will not see the actual boost psi with turbo(s) upgrades. The Attitude will backdown Juice fueling up to the 100% level, but you will still not know what actual boost you are running if you only have the Attitude. Like I said this is not a big thing to me, just letting you know that the boost readings are misleading when you get over 36psi.



BTW you do understand that backdown of 100% is only stoping the Juice fueling. You are still fueling 100% of what ever other stacked boxes, downloaders and normal ECM going on.

Thanks for the heads up. I had a full set of gauges in my 03 and have not done anything to the 05 yet. I was looking at the Attitude as an all in one but not so sure now. It would be nice if they had trans temp too along with an accurate boost gauge.
