is every engine getting set at 60% throttle and 2000RPM for finding where to set tq based fuel ? or am I trying to find maximum TQ at 60% throttle? looking at this LMM file the truck is saying its making 710 NM tq at 60% throttle and 2000RPM but at 60% throttle and 1400RPM its making 850, would I make changes to the fueling at 710 NM TQ and 2000 RPM or at 850 NM tq and 1400RPM?
when i make these changes would i want to smooth the whole table up to the top or just go a few rows above and one row below my first line of changes?
after these changes are made Im assuming I need to change the Tq output on the pedal position mode to desired TQ, how do I go about making those changes? would i figure out how much mm3 I increased in a percentage and add that to the requested tq output on this map or would i just make it to a higher tq number that it will never see?
heres a few screen shots of the tables im looking at, if im doing this correctly the maximum mm3 that can be looked up by the ecm is 120mm3 so i can go to 120mm3 and im wanting to set it to 130 mm3 so that if it fluctuates by a few mm3 the truck wont derate correct?
Kyle,
I'm finding it difficult to track your questions with the way you've phrased things. Maybe you could take a second to tell us what you're hoping to achieve instead of asking if something is correct. I've attached a couple of quick definitions of the tables you mentioned below, maybe that'll help.
Desired Torque - table to lookup what torque the ECU will target at a given TPS and RPM
Tq Based Fuel - table the ecu uses to translate the targeted torque into a fuel rate, which is then further used to lookup fuel pressure and injector on-time (pulsewidth)
