you may never go over 8100 RPMs , the reason we had to ditch the OEM PCM and switch to Haltech in my 05 is because my 392(6.1based stroker) is hitting 8600 thru the traps.......but your tutorial here is spot on , thanks for taking the time to upload and make it very user friendly
In the video you stated that by adding the values for FA Stoich and PE Aircharge it would give you Lambda which you can convert to AFR. That is incorrect, using your numbers of .0688 and .0135 you end up with a FAR of 1 : 0.0823. FAR to AFR conversion is 1 / FAR = AFR, 1 / .0823 = 12.15 : 1 AFR to Lambda conversion is AFR / Stoich = Lambda, 12.15 / 14.7 = .827 Lambda Being someone that is new to Mopar tuning the first thing I did was create an excel spreadsheet to convert FAR to AFR and Lambda since that is what I am used to. Never understood why anyone would use FAR or AFR since they are fuel dependent, Lambda never changes regardless of fuel composition and AFR gauges are actually Lambda gauges that convert the data to AFR.
Randy, Does the 5.7 like to be leaned out at WOT, vs factory numbers, to make more power? Like your stock table, my Challengers Aircharge enrichment numbers top out into the .02xx range. That equates to ~11:1 AFR when added to the .0688 base number. Decreasing the enrichment to .0135 will lean it out to 12.1:1 Sound about right?
I have a wide band installed. At wot I'm running .88 lambda. Is 1.0 target or keep alittle rich like .91. I've read that about .91 or .92 is good for torque
Good grief, my '14 R/T's stock PE is targeting an 11:1 AFR! That's slobbering rich, to me anyways. Your PE value of .0135, + .0688 base, puts AFR at 12.3:1, which is where I've seen best power made on SBC's. I know these aren't SBC's but power-producing AFR shouldn't change across brands. It's still just a cylinder, with an air/fuel charge in it. Did Dodge just play it safe with WOT enrichment values?
I have a question please. I've been watching you videos and they have really help me get my 5th gen Ram more responsive and overall drive better so thank you. My question is, if the max throttle voltage is 3.80V why does my throttle only show 86.7% open? I've tried increasing the "Max Demanded Throttle", "WOT Setpoint" & "TPS 1 & 2 Max Voltage" but every time I get on it I get a throttle issue appear on the dash and the truck goes into limp mode. The scanner shows 4.26V & 95.7% before the error comes up and it goes into limp mode. I've reset the max voltage back to 3.8V and no more errors for now. Thank you in advance.

Thanks for the explanation of mopar systems/ big help in filling in some gaps
Thank you for your time. Much Appreciated !
Engine rough ideal after doing all this on 2015 dodge 5.7
Excellant info! Thanks
Please do tuning on transmission
Appreciate the info!
Thanks man!
Gold!
You have any videos of a jeep 6.1 procharged having trouble tunning it

Sound about right?
On the pratio table. Are you setting that at the .0135 also as a starting point
My 2011 ram 1500 doesnt have ramp rate for electronic air flow. Is there somewhere else i can set throttle sensitivity?
I have a wide band installed. At wot I'm running .88 lambda. Is 1.0 target or keep alittle rich like .91. I've read that about .91 or .92 is good for torque
Hi I have a question. The FA Incr and Decr set at .5…. What does that .5 mean? Is the 1/2 percent increase? Or a .5 increase to lambda Stoich?

Hptuners doesn’t always read properly is the big issues
100% is actually past the point of being all the way open and closing off again theres no stop like with a cable throttle
Am I am to put my throttle response and sensitivity back to stock factory setting with out effecting the current tune I’m runnung
Out of curiosity on the MPH area, the lower the number is when it hits power enrichment? This is on a 2010 Tacoma by the way.
Some of them are a little goofy in the description, I’d have to see it
Yo bro can you help me with this if I send you my file & help with my trans tune
