I have a Predator for my 07 SRT Charger and everything is good BUT I am helping a freind who just got a Predator for his Daytona.

This friend is a mechanic for Dodge but needs some hand holding when it comes to using PC's

He gets that message that says he needs a Calibration update when he ...

I am using Dataviewer version 3.1.7.5 with the U7135 Predator firmware 9r05 on a 2007 Dodge Charger SRT.

I am finding that the data which is displayed where you put the cursor on the chart is not correctly lined up with the time stamp.

You can see this in the two enclosed screen snapshots for the ...

Thanks to MikeL - I will give that a try tomorrow and post back my results.

Quick - Thank you for that very detailed answer. Quite interesting how that drive by wire system actuially works.

I grabbed that answer and added it to my Word file that I have been buildiing which I am building. It is a ...

"Hmmmmm, Why in the hell is your throttle plate fluctuating while your foot is to the floor!!??? "

Thanks for the VERY useful reply.

In my writeup above, I picked up on the fact that the throttle plate position was bouncing around even through I had the car floored.

From what you say, I ...

I did get lucky and managed to have reset my laptop log,restarted logging and within 2 minute,I got that stuttering problem.

By lucky I mean that I have a log file that is only 3 minutes long and has only 2 places where I floored it so it makes it easy to study the data.

I have enclosed a screen ...

The enclosed log has a note of two time periods I would appreciate someone looking at for me.
This is where I went from rolling at around 35 MPH and floored it up until the mid 70 range.

This is the Canned 93 Octane Tune W/O CAI on my 2007 SRT Charger ...

Thank you for replying.
I will put the tune back as you suggest and see if it goes away.

I am able to be more specific on this after my drive today.

Had a solid hour drive up and back to visit my folks and the highway has a 65 mph speed limit. I had plenty of chances to mash it.

It did not do ...

My car has 15,000 miles on it with the Mopar CAI and I only use 93 Octane gas.
When there is a sticker on the pump , I make a note of it and the most I have seen is 10% alchohol in the gas.

I did the 93 with CAI performance tune last week and it really ...

thanks for the info.

the scanguage hp # is useless anyway because the omly thing one would want would be the max value and it has no logging capability.

Mike,
I will change to the 93 octane CAI tune ASAP per your advice.

What do you say about my question regarding the Mopar CAI that was asked in response to the fellow who said that it was a useless CAI?

Or does that fall into that almost religious area where some folks say that CAI;s do nothing ...

I have a stock car with the sole exceptions of a Mopar CAI, which I understand adds no horsepower and has no other advantage, and a 185 degree thermostat. Nothing else. Pure stock otherwise.
