GrannySShifting, the OS is 68070551AA version 4.8.7 Suite 5.0.4

No exhaust leaks now, but had broken bolts and leaks before.

Thanks for reply

Most insightful posting, thanks all.
I would like to get some confirmation with my VE table readings and settings, with ANN disabled. 5.7 Jeep GC 2010 model with Eagle head, stock exhaust, but cats...

I have been using the DTE PedalBox unit for years with very happy results. If gives an extended range of settings from stock to wild.

following with interest.

Rob2014, you explained this very well, thanks.
I helps when new members are given clear understandable answers.
By the way, I fully agree with your explanation.

I have not visited the forum for a while. My 2010 GC stock has NN disabled. I smoothed the VE tables significantly. This gave a smoother drive and better fuel consumption.

Barra, yes the hysteresis is like the upper and lower spec of the temp range. It is important to set the low, med and high speeds. I have a 88degree C thermostat and high @103C, medium @98C and low...

Thanks for feedback

Yes, please tell.

I have not visited the forum for a while. Turbo2gnx, I have no idea what you are talking about, sorry cannot comment.

Since last post, manifolds sorted and also smoothed the VE tables alot and...

ngc1068, thanks for posting this plus the logs. I have a 2010 Jeep GC 5.7 VVT MDS and from my logs the MDS activates only at low RPM and below 60km/h and for short times. My MDS tune values are...

Thanks sPHYNX. I live at sea level but often go up country. Will check effect. Last time had the table still stock setting, but now have changed it to advance timing at higher altitudes. So I can...

Thanks for your comment. As I understand, this table is a direct adder to timing/spark and when the MAP reads the Baro pressure and finds now at higher altitude, it will automatically adjust the...

nobody can add comments about this? This Baro timing table can have a big influence on a tune.

I posted this a few days ago on the Dodge section that covers the Chrysler/Jeeps, but no response. Hopefully somebody here can give some info.

With reference to the Spark>Advance>Barometric...

With reference to the Spark>Advance>Barometric Pressure>Base table as shown below for the 5.7hemi.

I understand that as you go up to a higher altitude area as opposed to sea level, your time can...

Thanks HaasExp, I get it and it is as I understood with all the meaningful inputs form yourself and other guys (Hemituna, Ben Charles, Janettyracing) on my previous queries.

So, know what is your...

I found that 180 may be a bit cool. It seems the 5.7 hemi is more happy with a 190 thermostat.
I agree with GeForce, fist fit new thermostat and only then change the fan activation temps.

If I may chime in here. The FA in our tunes (factory) of 0.0688 = 14.53AFR.
It is true, that using a wideband stuck in the tailpipe of my Jeep at CL gave 14.7AFR.
I have also changed the stoich...

well done.

Taking a chance but, do you have ID 50120 and 50121 in the Channel list? They are Air-Fuel Ratio (sensor) and Air-Fuel Ratio Commanded (sensor).

Row axis should be same as in the VE table. Pressure Ratio and not MAP. Look under Maths>pressure>pressure ratio. Just a suggestion

Thanks guys, appreciate. I will post feedback if I, or when I, get it as I want.

I will try as you suggested. But, presently as from factory, DFCO is allowed above 54C. So if I increase this temp to 195C then DFCO will never activate, not so?

thanks david. My reasoning is as follows, rightly or wrongly, feel free to comment. I am looking at CL operation, with narrow band (stock) sensors.

1. The ECU uses to tune VE tables (bank 1&2)...
