Table switchover subpage of MembersPage/GolfGtiLpg
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

Egy 2 körös kapcsoloval képzeltem el az átváltást és 4 db relével ezek már be is vannk szerelve.A relék 30-as pontjára érkezik a jel a cpu felöl a 6,8ohmos ellenálláson keresztül. A reléktöl a 87a-kivezetés a benzinhez megy a 87-es pediga gázhoz.A reléket viszi az egyik kör a másik pedig a cpu-ba megy mégpedig a ECM18pin6-ra egy 2k7-es ellenálláson keresztül.
