s54/MSS54 Detune

If you limit Max Torque KF_MD_MAX_MD_IND_OPT
you will also limit HP.

Thank you Rosie - I have looked at those (torque/moment) tables, but haven't yet figured out how exactly the DME is using them. Have you had any experience manipulating the values within? Wondering if the DME would use it as a master of sorts to then make dynamic changes as needed for throttle, timing, fuel, etc. I would kind of think the same thing as applied to the max throttle opening - the DME by design would adjust (correctly) as needed to decreased air intake to lower torque and horsepower output. Also aware of Epic/Randy and know of many very happy customers, but I am trying to learn on my own on another DME. I had a standalone prior on another motor and love the flexibility it affords, but I also find the work done to decipher the MSS54 pretty fantastic and from what I see, for those who like to do things on their own, the options are pretty open.

JBAshland please try Randy at “EpicMotorsports”. He masters that MSS54 And can detune it for you to gain more torque and flatten it all accross the RPM range while decreasing peak horsepower. Very useful for racers when they need to qualify for a specific class and need to keep horsepower in check. Good luck !!!😀

Does anyone have experience/ideas with modifying the MSS54 to limit HP/Torque? Running an s54 in an e36 racecar and for classing purposes need to lower avg HP output. I know there are options out there to purchase a swapped detuned ECU, but the more I look and learn about what is available now in looking thru my .bin in TunerPro, I am starting to wonder if it wouldn't be too difficult to do on my own, perhaps starting with changing max throttle opening via KF_EGAS_MAX_WDK from 5000 RPM and up. I have access to a Dynojet, so could fairly easily test a few different configurations of throttle, timing, vanos, etc but wondering if anyone has experience/ideas they might offer beforehand. Thanks much.
