Huge Concern

[KRAZZZI]

First of all, i dont want to start any unwarranted rumors, but i read a post of someone that claimed a problem with the predator. Our charger is driven by my wife, and i have huge concerns if there are truth to this persons claims, but i need to ask. He quoted,


"Predator Tune disables my traction control - DiabloSport stumped....

--------------------------------------------------------------------------------

I found out the hard way in a rainstorm that my traction control is not functioning. Since the traction and stability control have always kept the car in check while in the wet, I gave it some gas...... &%$#@#$!!!!!

The light on the dash came on like the system was engaging but there was no response... All attempts to replicate this occurance have met with the same outcome including performing a burnout while power braking. No way it should let this happen with the traction control on... When I removed the tune, all went back to normal.. I've since gone back into the tune and ensured the ESP was "on".. No dice!!! Traction control doesn't engage.. DiabloSport claimed the tune had no effect on the traction control system...

Any ideas??????"


I am hoping that Diablosport have done all the appropriate research on this person's claim. I certainly cant sacrafice my families well being for some HP.

Again, i have no proof of such problems myself, but this person and many others believe this to be the case. Please inform me of any information in regards to this matter. Thank you.

I replied to your post in CForums. But anyway, ESP uses the same timing and torque management tables as the PCM. So, if torque management is reduced (which it is) then ESP will also be reduced. ESP is working in our car but it has a much higher threshold. Almost so high that it doesnt do anything. Since the tables are the same I dont think there is anyway around this yet if you want the TM reduced.

It was my post and I was told by a support tech that the traction control was not affected.. SRT8Tech's response makes sense.. Hopefully we can get a second opinion from DiabloSport guys...

Yeah, there are older posts all over this forum from DiabloSport guys stating the ESP is reduced proportionally with Torque Management. I personally have AWD so when it's raining and I just punch her and she just goes so I can't say how reduced ESP would affect 2WD or the added HP of an SRT over the R/T. I know that I don't like the reduced ESP in the winter and I go back to stock when there is a snow storm forecasted.

Back to stock in bad weather it is!!!
Thanks..

ESP is only reduced when we select "increase shift firmness"?

I assume this is the only setting that needs to be changed back to stock during winter?

My car gets real squirrelly on wet roads.

Even with ESP on, I have found myself side ways on busy roads. Not a fun situation.

AFAIK, Increase Shift Firmness only raises the line pressure in the transmission. I don't think it affects ESP or torque management directly, just indirectly.

I've often wondered what my dash console ESP button does, if anything, now that I've installed the Predator 91 CAI tune. I already knew to be extra careful in wet weather. I don't have a problem with the tune's settings because I understand their implications. Even on dry pavement I would recommend caution at WOT in a curve with increased shift firmness installed.

We wanted Diablosport to "unlease the beast" in our cars and that's what they did. Even at stock these are powerful cars that demand respect.

Ummm, when you have your foot planted on the floor *something* cuts power while the transmission shifts. How much and how long has a LOT to do with shift firmness?

I'm running the '93oct CAI' tune on my 07 Charger Daytona, and 'yes' the traction control is way-too permissive in wet weather conditions. The rear wheels spin and side-slip with just the slightest of extra throttle on take-off and around curves.

I'm not complaining because - as was stated - Diablo delivered performance as promised.

I believe we all would like an existing (or new) feature that will allow us to get back our traction when it rains (or snows). I have 93 octane gas in my tank, so I don't really want to go back to a stock tune for this. I'd rather just adjust a couple of 'quick' parameters with my programmer and keep my 93 CAI tune. Just what I'd 'like', if the Charger doesn't allow for this - then Diablo's hands are tied. But if Diablo can do this... please, please, oh puleeze...

I don't think it's possible.
The initial response by the ESP is to selectively apply brakes. Even if you left that alone, added power has the effect of powering through that to some extent. If you're talking about more torque management then you're moving back towards the stock tune.

Nothing wrong with running 93 octane on the stock tune. If you want to take advantage of the extra octane then you're back to the 93oct tune...

I know what you're asking for though. All the power and shifts but no wheel spin.

As stated before, the torque management uses the same spark table for traction control, we reduce torque management, we also reduce the effectiveness of ESP when triggered.
We can and have made custom tunes for people that have this concern, your shifts will be a tad softer but ESP will work more like stock tune.
Feel free to e-mail me your last tune written and i can set whoever wants this up with a custom tune.

Now that's customer service. Good job guys.

I'm sticking with the regular tunes though.

Just to clarify, cause I don't think I understood.

If I load the 91 tune, but do not increase shift firmness, is the ESP effectiveness reduced by the 91 tune alone?

The LX cars are very twitchy/squirrelly on wet roads and I prefer to have full stock ESP working in the rain, but still have the 91 tune working.

[johan]

The default tunes without doing anything to quick adjusts or custom parameters will reduce the esp effectiveness.

Many thanks to Johan for supplying the modified ESP parameters for my tune and answering some pretty basic questions (like, should I select 'Yes' or 'No' when the Predator asks if I want to reset all parameters during custom tune install? - The answer is 'Yes').

This is the customer service we ALL want!!
