Powerup

Benchtesting

If there was no torture (like running injectors without GND5 or flyback), the P259 should work. Thanks Marcell. I thought that those channels give an groundsignal for a led too. But this isn't the case.


In-car Testing

IAT

Q: Values off ntc-sensor in megatune seem to be incorrect:

1.while driving: 20°C

2.while standing still: 23°C

3.outside temp: 2°C

heatsoak isn't an issue I guess because off the close values in 1 and 2? Is there any calibration necessary?


Uploading firmware and config and tables

Make mtt\n

 perl bin/make_conf.pl global.h etc/config.txt etc/config.mtt
 perl bin/make_table.pl etc/tables.txt etc/tables.mtt

Just make sure the files exist in the specified location (relative to current working directory) and that's all. These commands depend on PERL, but only standart PERL libraries are needed, nothing special (like the Serial.pm for bin/prog.pl).

Make sure the global.h matches your firmware installed on the ECM. To be sure, run this from the firmware directory that you installed "vems.hex" from.

Also, you can check the MegaTune release package, many people are now using the .bat files because those do not rely on PERL (and PERL libraries).

uploading tables on genboard

Q: I have a problem uploading the tables.mtt file onto the board.

When I issue the sendfile command in Terminal program, the board starts to upload it into the memory(because I see the characters appearing on the LCD) but then stops (no "bye" appears)and doesn't go any further. I have to restart the board to communicate with the board again. I did succesfully uploaded the config and the tables a while ago. What can this be?

This doesn't sound normal. Maybe the uploaded table is bigger than the table-size of the firmware you are using? Some basic info is needed to make investigation feasible.

Make a zipfile of the following:

Next week I will have a router between my laptop and my internetcomputer and can display the behaviour of the upload problem better.

UPDATE:

upload strategy I use

Q: What I do is:

Other strange thing happens

Note: don't duplicate things. Eg. if you don't understand how to check firmware integrity, ask where it was suggested (not at a different place - when it becomes too big, it can be split to separate section or page, changing the original text to a link.)
