User defined for T42?

[DSteck]

Any chance we can get user defined parameters for the T42?

[GHuggins]

Not to sound like an idiot here, but what are the user defined parameters and what do they allow you to do? I've never used this in the editor - no idea what it is or if I need it...


Thanks

[DSteck]

If you have to ask...



User defined parameters allow end users to add their own things to edit. There's actually a significant amount that HPT doesn't give people access to, although 99.99% of people have no need for adding more.

[GHuggins]

I know HPT is missing a lot - we're working on trying to get them to add more right now BUT what would be required to add in your own tables? Different interface or tool? I'm getting tired of having to use multiple softwares to tune with... I thought this just allowed you to change table names or something - didn't know it gave you access to more tables... Simple throttle torque airflow definitions to kill the phantom light throttle cruise tm that people experience and O2 test definitions to kill start up lean outs after going into closed loop would be nice... Does this give one access to pull up more tables like this with HPT or do you have to use a third party software to do it?

Thanks Dave

Thanks Bill... I was wondering why I was seeing tunerpro being mentioned all of a sudden on here - guess I completely missed all of this / haven't used tunerpro in a while - guess I'll have to relearn...

T42 user defined parameters will be available in tomorrow's beta.

[GHuggins]

JSlic or Scott has already sent you several tables and keeps getting fought on it from what I've heard BUT basically where people are having tm randomly cut timing during cruise in bigger builds is due to the torque model low, med and high baro airflow torque model tables... O2's causing things to go really rich or lean during after start O2 test is due to their voltage settings... Oil pressure warning light settings are missing - you can technically run without oil pressure for quite some time right now before lights come on - to each their own, but I would like to adjust it... There are several map test such as boost maps, cat test, 2 other tm settings that are missing... I know you have efi - just open and compare... I'm happy as hell hpt has the torque editor, vve editor, E85 settings, injector tip temp and a few other things that are necessary, but would like to have some of these others added too...

Then I guess depending on who you talk to that can actually look in these cals with engineering backgrounds - they will tell you that the way we do it is more or less a hack - that there are several more torque modeling tables involved and how they relate - such as the torque model editor - you can change the eq ratio table - this is a direct airmass multiplier so should change the torque model right? Change it all to 2's - torque model still the same...

I know I'm ranting, but I really don't like chasing my tail sometimes only to find that another software had the tables and a simple change fixes the problems...

Then a little off subject, but any timeline on the ford editor tools

Thank You

Shitchea. Time to start mucking with the CAN stuff. Lol.

What are we missing?

Reverse lockout Solenoid Enable/Disable Speed for one (2010ish E38 Camaro LS3 Manual Trans)... I've asked a few times. Other software has it, my 2016 Truck Auto Trans has it for whatever reason. Then seems like only I have a 4000rpm limit for transients not sure why, not many others do.

After poking through A2L files that I've gotten my hands on, a lot. The overwhelming majority are parameters that nobody has a need to do anything with though. Personally, I'm trying to make tap shifting work on a 4L80.

Actually looked for this the other day - funny that an auto has some of this, but not in a manual cal that actually uses it...

{B5215} - If the engine oil pressure is lower than the values in this table for the time specified in {B5216} "Oil Pressure Low Time" the ECM will flag low oil pressure.
{B0524} ? Selects if axle maximum torque limiting will involve modifying the spark timing.
{B0525} ? Selects if axle maximum torque limiting will involve modifying the fueling.
{B0526} ? Selects if axle maximum torque limiting will involve modifying the electronic throttle position.

{B0529} ? Selects if the ECM will try to eliminate driveline clunk via torque limiting by modifying the electronic throttle position.
{B2510} ? If the traction control system has been disabled due to the engine RPM falling below {B2511} "TCS RPM Disable" then it must rise above this value again before the traction control system can be active again.

{B2512} ? The engine must have been running for this long before the traction control system can request torque reduction.
{B2520} ? Engine must be running for this long before the traction control system can reduce spark.

{B7007} - Once the engine has been considered to be in an overboost condition the manifold pressure must fall below this value to reset that condition.
B1505 - To stop the ECM switching rapidly between the open loop / closed loop temperature thresholds this hysteresis value is applied meaning the temperature change must be greater than this value before the ECM will switch between open / closed loop or closed / open loop.
B1506 - When the ECM is trying to determine if the O2 sensors are ready for closed loop and the O2 sensor voltage is our of range for this long then it is still considered not ready.
B1507 - The ECM must sample the O2 sensors in a ready state this many times before it is deemed the O2 sensors are ready for closed loop.

{C0612} - If the engine RPM is above this value then the misfire diagnostics can be enabled.
1515 - This table defines the voltage the O2 sensor output must cross to transition from a rich to lean or a lean to rich condition. Bank 1 ? This table modifies a different location than HPT
B1516 - This table defines the voltage the O2 sensor output must cross to transition from a rich to lean or a lean to rich condition. Bank 2 ? This table modifies a different location than HPT

If you find something you'd like us to add please open a support ticket and make sure to supply us with the .hpt file in question along with the table address & whatever description information you can, if we need to add something we typically have no problems doing so.

[07GTS]

ECM 4151 is this the low oil delay ur talking about jsllc ? and ECM 14110 is the low pressure/rpm threshold, and ECM 4150 is the hyst ..? i have adjusted mine in my tune assuming they work or are they OS specific..?

[jsllc]

I have no idea as a 2012 e67 or 2010 e38 do not show either of these. What OS and ecm are you running?

[07GTS]

mine is a E38 2007 (file says 2008 tho) OS is 12612381 my info is in "engine diag" then "general" under "oil" ill put pic below or i can upload my tune file if u want it

I pick my battles now. There's things I don't necessarily want everyone to be able to edit.

These are not listed in 2012, 2013 e67. Also they are slightly different.
