Default New developments in TurboEdit/OBD0 ECU Code

http://forum.pgmfi.org/viewtopic.php?t=4853

Read all about it...newer better code. Come get some...

Yes, finally a new stable codebase.

Vacuum column headers appear to be pretty accurate in TE in all bins. The stock MAP sensor bin displays column headers 100% correctly. The 2.5/3.0 bar column headings aren't quite right under boost - looks like the stock MAP sensor is getting used in the math somewhere...

The major changes in this codebase:

1. O2 Disable is now selectable from an option byte. You can control it by editing location 7FC0 (hex) in the ROM with a hex editor. This will be available as an option in TE soon.
O2 Option byte values:
00 = disabled
01 = disabled in boost, active in vacuum (default setting)
02 = on full time

2. Datalogging code is rewritten and greatly simplified. It is unlikely to work with any old datalogging applications, but there is a new version of ECUControl that supports it. MAP trace support in TE should come soon.
Changes:
-Uses the "old" send the byte you want to recieve, wait for response protocol
-Safely stores RPMLO byte corresponding to the RPMHI (047h) byte requested in RAM 0FAh. Proper sequence to log RPM is to send 047h (high byte) followed by 0FAh to retrieve low byte.
-Able to log raw O2 sensor signal by using command 0FBh
-Able to log raw ELD sensor signal by using command 0FCh
-Able to log raw MAP sensor signal by using command 0F8h
-Able to log "stocklike" MAP sensor signal by using command 036h
-Able to log "remapped" MAP boost table reference using command 0F9h
-Able to log VSS using command 06Ch
-Able to log TPS using 039h / 03Ah
-Able to log Barometric pressure using 034h
-Able to log IAT using 032h
-Able to log ECT using 030h
-Able to log any codes that the ECU is throwing by logging bytes 02Bh, 02Ch, 02Dh. (See explanation of disabling codes for interpretation of bytes)

3. Ability to selectively disable all error codes (Soon to be in Turboedit) See here for more info.

4. Sane column headings (see attached excel ------sheets / source code)

Enjoy!
