Since I have a hard time reading all those numbers and letters and formulas etc. and I have no LCD yet, I am doing as much as possible in MegaTune and the changes made there I will cut and paste from the terminal program Mcd command.
Using MegaTune 2.25 beta-2
Start by reading the MegaManual
- Opened MegaTune. Clicked on VEMS standard 12 x 12 (default).
- Starting with the settings tab.
- As per [manual],
- set the constants,
- Get the engine started and idling,
- Then set the PWM criteria,
- Then set the cold start and warm-up enrichments,
- Then set the VE table,
- Set the acceleration enrichments,
- First option under settings is "VE Table". Click on it, then click on tools. Click on VE specific and then Generate Tables. Fill in all the options as accurately as possible. I left my map at the default 20 100 100 100 as I am not really sure what it will be, but that sounds close. Next clicked "send to ecu" then click close.
- Did the same for the spark and the lambda tables.
- Noticed if I shut MegaTune off the on again, the tables are all reset. Save when shutting down megatune and when trying to open that file up in the file-open window, it asks me if i want to burn them into the flash, I say yes
- but it tells me my power is too low (this MegaTune message is harmless for GenBoard, but it makes sense to adjust battery calibration to read realistic battery voltage anyway, so the dwell and duty are not enlarged due to low reading) I clicked no but it kept asking and asking and I think it eventually did burn it in. Now, looking at all the variables that were in before, EVERYTHING is set to zero. We had similar report last week, it seems MegaTune can trash tables at startup under certain (yet unknown condition - very annoying). Anyway, when this happens, checking with mcd and mct wouldn't hurt to see if the readout/display is wrong, or MegaTune really trashed the config and tables inside the ECU. Keeping backup at all times is recommended. Tables were ok, config completely 00. I was originally going to just leave it at that and just go through and start from scratch, but in case I missed something, I decided to go steal someone elses and practice uploading the config and tables through the serial port.
- Re-adjusted the battery correction to read the power supply output voltage and all is fine. Time to re-read the manual.
