This is the first fixes release (FP1) for the LTS 202402 firmware version. As with previous fix pack releases, this contains no new features but resolves a number of issues that have been found inline with the intended Long Term Support of the 202402 release.
The specific fixes in this release are:
- VVT angle readings (and therefore closed loop VVT control) were not working when:
- The Poll secondary method was used or
- Neither the fuel or ignition were set to sequential
- Using a 2-stroke engine with the Basic Distributor decoder resulted in an incorrect RPM reading
- The Flex fuel boost adjustment was being added multiple times to the boost target
- The tacho sweep function was not functioning due to a regression
- The stepper idle control was operating at half the commanded step value during cranking (Not during running)
- Prevent a potential oscillation of the fuel pump output when the engine comes to a stop
- The TPS reading over OBD2 and CAN broadcasts was incorrectly scaled
- Fix CAN initialisation on Teensy 4.1
- Attempting to use digital pins > 34 on a Teensy 3.5 would not work
- Fix an incorrect pin mapping for coil 6 on the SPECTRE board
As there are no new features or other major changes included in this release, it is strongly recommended for all users of the 202402 firmware to upgrade to this version. This release can be loaded through SpeedyLoader with no need to change your ini file in TunerStudio.
