Progress 9 July 2006:
Firmware r045, Megatune for 1.0.36
On conversion from firmware r023 several options were left unset in config which threw everything off quite a bit. Be sure to review all pages and set config accordingly. Enabling antilag and launch by accident will prevent engine from running.
- Fuel cut was defaulted to 0kPa which confused me for a few minutes when it would fire while cranking but never start.
- Autotune still wants to drag my VE values down to zero, even though they VE figures are fairly accurate. Anyone else experiencing similar problems?
- Spark cut idle control works nicely, but now there are several pages for idle settings. Consolidation possible to avoid confusion?
- Having trouble spinning motor faster than 6000 rpm. Can someone review my config (good03.msq) and recent datalogs and give some comments please?
Progress report (Nov 11):
Firmware r023
Starts and runs! Idles fairly smoothly with only set-screw holding throttle body at 4-5% open. Drove around a little bit, runs very well and all parameters look good. Accelerates much harder than when K-Jet was running the show, until it gets to the sections of fuel map I haven't tuned. I'll be reviewing logs today, updating tables and doing more testing, provided the rain stays away. Thank you, everyone, for your help!
- Notes:
- * VE table values had to be doubled even though req_fuel was set at value recommended by req_fuel calculators.
- * Top dead center after trigger was retarded by 30 crank degrees.
- * Use MegaTune to enable/disable features (misc_out, boost control, iac, etc). Disable values in config.txt inconsistent between feature channel outputs.
- * LCD display is cutting out, displaying with strange offsets, otherwise acting funny. Vibration getting to headers or wiring elsewhere? Will test.
