The engine works fine for LPG and gasoline with 1.0.75 firmware with [these config and tables]. With 1.0.75 firmware a notebook is needed to switch to other set of tables.

We upgraded to 1.1.53 firmware.

See TableSwitch. We made it switch tables controlled from EC18pin6(mcp3208 analog.ch.6). 5v / 0V

* 5V running on gasoline

* 0V (pulled down with a switch) running on LPG

The same set of injector outputs control separate set of gasoline and LPG injectors (the switch also switches a relay).

Preparing the switchover tables

upgrade to 1.1.53

* upload 1.1.53

** we had to use an older (2008-10 ?) v3gui because new vemstune popped up warning for 1.0.73 every second (!)

** MembersPage/GolfGtiLpg/SenzoR says

** coolantfactor "2063_256"

** airdenfactor "2252_256"

* upload 1.1.53 sanity config, eg [this]

* upload mcd and mct dump from 1.0.75 gasoline

* review missing variables

** knock_chan=F0

** multitooth advanced filter, see values (find on GenBoard/UnderDevelopment/FirmwareChanges when semantic changed)

** Set all unused outputs to FF (disabled). grep _channel file.vemscfg Even vvti and warning output channels (do these NOT appear in vemstune "all outputs on one page 2" ?

* run setup on bench

* verify engine operation with gasoline

* save LPG VE and Spark tables in mct format (currently in megatune format)

a more complex way to upload - only left here for completeness. This was the original thought. The TableSwitch worked better.

* prepare slightly changed config files (confswitch=.. different, see GenBoard/UnderDevelopment/FirmwareChanges)

** confswitch=C6 does load_variables(1) if mcp3208 ch6 goes low

** confswitch=D6 does load_variables(0) if mcp3208 ch6 goes high

* one way is to generate gas and LPG config.mtt files.

* We try to upload with vemstune, and only do the special burn command manually (mcS0 and mcS1)

** confswitch=C6 (decimal 198)

** mcS0

** confswitch=D6 (decimal 214)

** upload LPG specific tables (VE and spark)

** mcS1

* append the gas and LPG tables.mtt to the end

** edit the files manually, change the trailing mcs burn command to mcS0 and mcS1
