5.7 Hemi Pedal Commander Feel

[curbaliciousdef]

I'm new to tuning and trying to replicate the throttle sensitivity of my old Edge Pulsar V3 in Perf. MDS off mode. I've studied several other hemi tune files for Hellcat's etc. and this is what I've got so far. It's definitely better but not quite there yet. I've adjusted ramp rate, max demanded throttle and gain in electronic throttle as well as WOT threshold in Tq management. Also updated WOT threshold under power enrichment to match. Any advice would be greatly appreciated!!2015 Ram 1500 Laramie 4x4 5.7 Hemi 8HP70 First Tune rev1.hpt

Try lowering your numbers in your airflow tables above .5v by 10% until you get the feel you want.

wot threshold in pe does not make a snappy tb

it is for fueling

You're talking about the throttle body model airflow table correct? And thank you for your time, I appreciate it!!!

Thank you! I figured that I just made the value match because I wasn't sure if it would throw anything else off and I noticed it matched the WOT thresh in every tune I studied

Update: I figured it out and nailed it! Big thanks to LilSick for putting me on the right path!!! What I did was adjust the pedal % power table for my 4x4 high drive mode 1 table by shifting the cell values left 2 places thus giving me more throttle request with less pedal input. Made everything 3.0v up to 3.8 100 then just smoothed the table once from 0.1v-2.8v. Also updated WOT v to 3.0 as well in PE and ETC throttle and changed throttle ramp rate from .02 to .2

Improved further by making the 0.1v values 8 then interpolating the values across the chart from 0.1v-3.0v. I'm still learning so don't roast me, but that would have saved me a ton of time the first time around lol.

Next up is, re-scaling pedal v .

what he means logan is you dont need 8 columns to go from 0 to 1v

ya follow me?

Here's my Niece's 2014 Ram that she's been beating on lately, ironically enough we're using 8 cells for 0-1.0 , I would rather use 8 from 1-2v but she's doing a lot of stop and go with this truck, the other tune is much more aggressive 0-1v and very "light switch" from 1-2v.

Remember.
Table 13530 WOT Pedal , is where you jump to WOT spark
On her 14 we set 13530 to 2.41V and PE (table44442) is set at 2.05v

This is the one from her "bracket/Gamblers" race tune.
Pe comes in at 1.625V
WOT comes in @ 2v.
This tune she can feather the throttle between 800 and 1k ft and still be on WOT spark and Max PE........Now I'm not suggesting either one of these for a stockish street truck, just examples of what we can do with this tables.
