Earlier versions & revision history

V3.000 (2010-Feb-25) - WARI Version 3.000

• Improved robustness of code for communications between microcontroller and EEPROM chip, to better handle electrical interference, and prevent potential ECU resetting or settings corruption 
• Added Ignition Output test function (on 'ECU Data' window in WARI, with the Injector Test buttons)

V2.000 (2009-Dec-15) - WARI Version 2.000

• Added Volumetric Efficiency tuning
• Added EGT-based aux outputs
• Added ignition firing after TDC
• Optimised Nissan 4 and 6 cylinder unique triggers, particularly for faster starting
• Added optional filter with 1 second time constant for temperature inputs
• Updated the idle control functionality (fixed A/C idle-up, enabled separate idle efforts to be added for different elec load inputs, changed the target RPM strategy to take the highest of the additional RPM values rather than the sum).
• Added MAP prediction "drive by wire" mode for less sensitive throttle thresholds
• Added ELM327 mode for once only at startup
• Added 0-4V Autometer ES PRO calibration on external input
• Added calibration for Jaycar KC5486 0-5V oxygen sensor on external input
• Added calibration for Dynojet 0-5V oxygen sensor on external input

V1.0Q (2009-Aug-17) - WARI Version V1.13

• Added MAP prediction for greatly improved and simplified transient throttle behaviour

V1.0P (2009-Aug-10) - WARI Version V1.12

• Corrected tacho on aux output for 50% duty cycle
• Added transient throttle ignition advance
• Added logic-only inputs based on logic-only outputs
• Added boost duty cycle scaling based on percent TPS
• Removed 'Enable Datalogging' input feature
• Added aux output based on battery voltage
• Improved MAP and TPS resolution, now 1/16 of a kPa or Percent for interpolation
• Removed MAP filter
• Corrected bug with the closed-loop fuel max TPS
• Added 2-rotor wasted leading, alternate/DF trailing mode
• Added 2-rotor direct fire mode
• Added ELM327 Scantool error correct mode @ 38400 baud
• Added new tuning mode: 1=MAP, 2=MAP, Pri = 1, Sec = 1x2, Ign = 1
• also added injector 3/4 trim (rear rotor trim), when in this tuning mode
• Fixed bug with max RPM and max Load for closed-loop fuel control
• Added min load for closed-loop fuel control
• Fixed bug with WOT enrichment
• Added special trigger mode for Nissan VQ30 engine
• Added AEM UEGO 0-5V on spare input
• Added protocol for Innovate TC-4 thermocouple interface device, on second serial port
• Added support for Gen 5 Suzuki Swift triggering, with VVT and sequential injection
• Improved accuracy of VVT angle detection
• Added option for idle-up on each close throttle event (dashpot)
• Fixed bug in TPS cutoff for asynch accelerator pump
• Modified DC5 trigger mode to handle Yamaha XJR trigger

V1.0N (2008-May-07) - WARI Version V1.11

• Traction control added
• Launch control added
• Changed aux output to correct hysteresis bug on general outputs (introduced in 1.0L) - now only does tighter limits on VVT functions
• Modified Subaru 99-00 code to allow cam pulses to overlap crank pulses
• Added control over maximum boost and duty cycle for each gear
• Added gear learning
• Added a maximum control authority for wastegate control
• Added variable timeslice for idle control
• Added sequential injection for NB MX5
• Added 'Enable datalogging' digital input type, which forces the gauge data to be sent out through the first serial port (usually for laptop). This allows external dataloggers to read the serial signal

V1.0M (2007-October-16) - WARI Version V1.10

• Divide by two with missing teeth trigger added
• Aux out 4 inverse of Aux out 3 added for use with certain idle motors etc
• Added AND and OR based outputs
• Added Engine Make and Model selection
• Added stored timing offset
• Faster ADC
• Faster throttle pump response
• VSS code changed for greater accuracy

V1.0L (2007-July-16) - WARI Version V1.09

• Reset on camshaft missing tooth added
• A do not update already tuned for adaptive tuning modes added
• Tacho on Aux output revised
• Nissan trigger code optimised for higher rpm
• Digital output revision for more tolerant operation (ie hysterisis, non exact values etc)

V1.0J (2007-June-14) - WARI Version V1.08

• Added 2j Tech Edge wideband sensor
• Added single and two cylinder engine configurations
• Added coolant hi and low load enrichment
• Improved ignition timing at very low rpm

V1.0I (2007-May-16) - WARI Version V1.07
