LML DSP-5 Custom Tuning

LML DSP-5, actually SOTF

Switch on the fly (SOTF) tuning on the LML Duramax platform does not provide 5 individual maps like previous year duramax ECM’s. It simply utilizes the fuel rail temperature to limit the total fuel quantity (MM3). It is the electronic equivalent of putting 4 different sized wood blocks under your accelerator pedal.

Whether tuned with EFILive or EZLYNK, your ECM will only have one calibration. Therefore we don’t offer the SOTF (DSP-5) option for LML since we don’t see the added value and prefer to keep the fuel rail temp functioning as the OEM intended.
