The following additions are all baro related...
- Added A Baro Vs VE Multiplier Table
- Added Option To Choose VE Multiplier Or Altitude Adjusted MAP For VE Lookup
- Added Option To Choose MAP Load Variable Or Altitude Adjusted Load Variable
- Added Option To Not Update Baro During Engine Run
The Baro vs VE multiplier table is used only if the option 'VE Multiplier' is set. It allows for VE adjustment when the baro changes, in GM config (and as it is in the V104 bin and cal file) it adds fuel as the baro drops. This is due to the engine being more efficient at higher altitudes - reduced exhaust back pressure means the engine VE increases. You can adjust the table values if you want to remove fuel at high altitudes due to lower air density.
There is now an option to also choose MAP Load Variable Or Altitude Adjusted Load Variable for lookups. The altitude adjusted MAP load variable is used by default, if you dont want baro adjusted lookups (excluding VE) then clear this option. If you have this clear (use MAP load variable), the option for VE multiplier and clear the multiplier table there will be no baro adjustment at all. Some people would prefer to not have any baro adjustment so this can now be done.
The option to not update baro while the engine is running is for those running boost, but it also means if your driving up a mountain the baro will be the same as it was at the bottom and fueling changes wont take effect until the engine is turned off and back on again.
These are all boost additions and work the same as the existing non-boost tables so shouldn't need any further info...
- Added Boost % Coolant Contribution For Charge Temp Table
- Added Boosted Cold Engine AFR Tables - Map A and Map B
- Added Coolant Advance vs Boost MAP and Temp
- Boost Knock Logging
For those running boost one table I think that was lacking was the ability to add/subtract spark advance as the charge temps rise so added..
- Charge Temp Advance Atmo And Boost Tables
The following changes relate to VE Learn..
- VE Learn flag part of ALDL message
- Changed Wideband A/D Into WideBand AFR
- WideBand VE Learn
The wideband VE learn uses the wideband input (be sure to setup the new wideband VE learn parameters to suit your widebands 0-5v output) to learn the VE in the 20-100kPa region only. Its not limited to just stoich like the narrowband VE Learn. Its a slow update much like the existing narrow band VE learn, its not a magical fix for a VE table thats miles out and wont save your engine if its mega lean and going WOT. It wont work under boost, that bits up to you! If both narrowband and wideband VE learn options are set to active, wideband takes precedence.
The other change is the ability to link flexible outputs together. In the flashtool you can choose either or both axis of a flex output to be controlled by the DC of another flex output. Should be able to make it do some good stuff now
There is also a VE Learn flag active flag in the ALDL output.So if you do upgrade be sure to check the new tables, they are not populated with data when the cal is migrated. Its up to you to set them up in TP to your specific requirements. If your using the bin or cal provided in the V104 zip then all the new tables are setup to suit a standard V8 or V6 so its a case of burn and your away.
