rusEFI fuel control roadmap 2020

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
