HPTuners as of 3.20.18 is still missing additional tables. I've read about the flowchart for how EcoBoost works, the problem starts with desired torque and the ability to change it. The problem is gaining access to the tables in HPTuners to allow the changing of desired/scheduled torque. ![]() I figure it is the same way with EcoBoost. Some seem to tweak the WGDC tables, but I've never had to touch WGDC on my GM LNF tune because the ECU takes care of that to maintain the desired torque/boost. I always populate the inverse torque tables with the correct math, but like we have found, tweaking it isn't the right way to go.įrom what I have gathered from folks using SCT PRP, the driver demand table needs to be modified leaving the torque/inverse torque tables alone. If I kept it lower, like 1.7 load at about 350-400 ft-lb, I was able to get some results but not the results I wanted. Basically I was commanding too high of a load at one point which triggered the wrench icon / ETC FMEM. I understand why I got the wrench icon, but I had to try out the torque/inverse torque tables to see if I could do anything. The only people getting any kind of results are using SCT or paying for a tune from a vendor. Reading the other EcoBoost owners trying to use HPTuners to tune, they get the same results trying to tweak driver demand. ![]() The driver demand tables, as of VCM 3.20.18, doesn't do anything for the SHO.
