Roadmap Fuel
This is a summary of what we hope to achieve over the next few months in terms of fuel control.
Fuel control roadmap V0.1
Now ->
- Fuel algorithm improvements
- MAF - Fix VE map tracing in TS, some progress on #1398 - Fix spark map to use the cylinder air charge as Y axis
- Alpha N - Move fuel and spark table to use the VE table
- Change to use % of ideal cylinder filling at the Y axis making AN a VE based mode Tickets: mass air flow output channel scaling needs help Add VE/AFR tables to Alpha-N strategy Updates to fuel algorithms
Jun ->
- Ram and space savings - Deprecate the pure voltage MAF method (done?) - Removal of old unused fuel and spark table
- Reduce the resolution of the VE and spark table to 16bit.
Jul ->
- Stage 1 dual bank control
- Move to a dual fuel state system (Requires cylinders to have an ID for bank 1 or bank 2, reads the correct MAP/MAF/TPS for that bank and then keeps a fuel/spark state on a per bank basis~
- Implement MAP/MAF/TPS/Lambda swapping based on the bank ID
- Implement Pulse width and Spark angle on a per bank basis
Oct ->
- Stage 2 dual bank control - Implement dual 6x6 trim tables (one per bank) either manual or short term trim - Potentially set up short term and long term 6x6? - Create 5x5 (6x6?) TPS to MAP/Cylinder filling transfer function table, Use TPS vs RPM for this table with values in VE to create a limp mode activated on MAP or MAF failure #932 #919 #468
Nov/Dec->
- Advanced fuel control
- Fuel Consumption #45 #426
- Begin work on advanced algorithms
- Cylinder mass based control
- Inlet/exhaust pressure ballance
- Torque demand (too hard?)
- Returnless fuel math? #954
- Can we reduce AE tuning via an auto tune? #944
- Fuel gauge? #219
- Dual tables? #289
- Non-linearity correction #275
- Fuel autotune (non TS) #247
- Closed loop changes #355 #348 #384
- Flex fuel #540
- dead time autotune #492
