Open Issues ToDo
- Is it possible to move Ignition out 0 to one of the P259 pins ?
- currently no. It would require a firmware modification. What would be the reason for it? The IGBT can handle anything (and more) that the p259 can.
- If this is about a HW change, and a low voltage (vs. 400V capable, such as a DPAK IGBT) open drain output is sufficient for you, I recommend using a simple uC output or 74AHCT132PWR or 74HC259D and use NPN resistors (such as PDTC123 if low current enough, or other SOT23 or ULQ2003 if current demand is higher).
Looks like bins change but Megatune displayed is fixed and must be edited to reflect the new bins.....I guess I am one of the crazy ones that wants to alter the Warmup Coolant Bins. These have not (yet?) moved to flash, if they do not respond to Config File Changes, than it's a megatune issue. Configure outside megatune:
- Manmcd dump
- extract the warmup_clt_range[]= section as you only need that
- save as config_cltrange.txt
- edit
- add +40 to the Fahrenheit temp
- convert to hexa
- make mtt
- send .mtt file to the ECM via TerminalProgram
- remember that you have the new bins in the ECU, not the values MegaTune shows
- when tuning warmup enrichment, MegaTune might even recolor the wrong bins, so take care
An example of how CWL, CWH, AWEV, AWEV_Temp..., and AWC affect cranking and afterstart can be found at MembersPage/BillHart/CrankingAfterStart.
Open Questions:
- Is it possible to move the injector firing point within the 720 degree cycle for a primary/no secondary trigger system?
- no. Actually, 720 degree cycle does not exist (as far as the ECM is concerned - the valves know about the 720 degrees cycle of course) without camsync. Only a 360 degree cycle exists. It would be possible by analizing the MAP signal or the RPM angular speed variations, but it's not implemented. Thank You Marcell, Bill Hart

Projects Underway
MembersPage/BillHart/WinMobileLogger Win Mobile platform to Fat32 memory card logger. Looking for SIPR examples, if any, to ease the adding V3.3 query to Win Mobile code.
- [VR_Emulator] is a parallel port based Op-amp circuit that provides a plus or minus pulse about zero to emulate a VR sensor. You build the Basic routine to generate the crank (and cam)input wave form you need. Drop me a note if you need my QB code as a starter.
- we usually use stereo soundcard nowadays. It has many advantages, like processor overhead is small, amplitude can be varied, code is not hard to port between platforms, and it can even work without any executable (wav-s can be played with standard tools).
