is there a reason why hpt is missing the vgt tables?? does anyone else see them?? SCT has them but HPtuners doesnt.. this is 2017-19 file.

SCT BOOST PRESSURE SETPOINT.png
That looks right, labeled different. Im also curious why they both dont have ebp pressure set points even though the truck uses ebp. ebp should have some control on the turbo side of things.I modified that to make a HISS tune and it didnt do anything. im trying to get the vgt to 100% at idle and that didnt work. also modifed boost pressure base setpoint and still nothing.

Where did you modify it? Log current torque and see where it's at during idle, should be between 0-110ftlbs or 0-150NM. They are the same tables just axis are inverted and in Ft lbs instead of NM
Did you try modifying mode 3 tables?
i tried modifying all the boost pressure set points, boost control set points, every map tables, and vgt tables. put them all to the max from 500-1000 rpm.. truck still rumbles at idle.
i figured it out. its in this table.. Capture.PNG
Yeah that'll do it! I assumed you'd changed it already and was like what else could it be lol. Glad it's working for ya!Originally Posted by Powerstrokecustoms
the crappy part is, in sct they have boost pressure control upper limit and lower limit. and its under diesel boost control threshold. and its labeled as a upper limit PCR controller. I was like come on. i do way more tuning with SCT then HPT just because 1. there's just way more stuff to modify and 2. you can save the mods you do to a specific table as a value file.
Has anyone figured out how to adjust this more adequately, recently installed a no limit fab 64/67 turbo on my 22, reset vgt and have had issues during certain driving conditions. I have logs that can be provided if anyone wants to help me tackle this concern. I know it has something to do with the VGT tables that are currently on the tune as they are set for the smaller size turbo.
This should be taken as a grain of salt what i am saying but it makes alot of sense coming from the HP academy diesel webinar classes, they do state when doing a 10% or 30% or any % of value change in 1 table to do this in ALL the table that have the same two Axis reference matches other tables, so if OTHER RPM VS Torque tables are there to do the Change in there too BECAUSE 1 table can be for Car Warm up operation's........1 Table can be for once the car is fully warmed up....1 can be for DeAcceleration......1 can be for Upper Turbo RPM limiter and Ecetera (ECT)
by doing this Powerstroker would have eventual hit his change in all tables.....Thing is we have a Diesel and AFR isn't really a thing of concern unless we are dumping a shit load of diesel fuel then off course worry lol
To help you with your question LSXhunter1......change all the same axis tables if the change does not execute in real time.....for another example is if you ONLY change your VGT table the ECU wont do anything because you have not change the Desired boost pressure table... so again don't be scared to keep change tables to make your change happen.
