I've upgraded to 1.0.53 and even with the ALS settings fixed I see that the ALS Switch On is showing in MT and the spark advance is showing -0.75degrees. '''Q''' Can anyone suggest a solution please? '''A''' In post 1.0.46 versions ALS and launch inputs are configurable, set als_launch_input=FF for original behaviour, see GenBoard/UnderDevelopment/FirmwareChanges (since 1.0.46) for details. http://vems.hu/www.vems.co.uk/VEMSInstalls/Simon86/config328.txt http://vems.hu/www.vems.co.uk/VEMSInstalls/Simon86/tables328.txt Emils answer:, got offline while writing, so someone else got in before me, but i'll post anyway. 2 problems * spark advance is constantly -0.75 ** You have configured ign_balance = FF , which automatically limits advance to maximum -0.75, Change that to setting = 00 instead, for full advance range ** Megatune: Extras, Advanced ALS, Ignition offset (or similar), mid page. * ALS Switch On ** Is it wired up at all? make sure als_launch_input = FF, you have ... = F0 , these other channels require a pullup to be inactive, where the old channels SDA + SDL or something have internal pullup. ** Megatune: Select "old" settings in both Advanced ALS and Launch control menus, both under "Extras" dropdown menu. ** This has also been a indication for me that something is wrong with grounding, where the ECU experience a brownout during powerup, that is with 6 or more 2 ohm injectors. Please report back here for further analysis if the config changes doesnt help, im pretty sure these problems are config related in your case ----- ----- == Notes to self == http://www.vems.hu/wiki/index.php?page=EasyTherm note that only the boards without the AVCC mod use the _287 files. The rest use files which end with _256 MembersPage/PhatBob/BoostControl - Working out the correct connection and configuration for the webshop pneumatic valve. WebshopIgnitionOptions - explains the webshop ignition coil options ----- As requested on AFreshTiny page. AFreshTiny 5A control. It would be good if the 5A control could be activated in a similar way to the Genboard Misc outputs. Trigger on/off on: * Lambda - so that the system can turn on a 5th injector or warning light. * EGT - to trigger water injection, 5th injector, turn off boost solanoid or trigger a warning light) * Analog Input - to set on off points with either boost or tps - would work well as a 'soft' TPS switch to turn on n2o systems or any of the above suggestions. ----- '''Compulsory''' MembersPage/PhatBob/PurchasePage ----- '''Previous Problems Worth Remembering''' MembersPage/PhatBob/MagnettiMarelliSensorProblem ----- '''Handy URLs''' A list of Ecu Sensors and their functions http://www.pgmfi.org/twiki/bin/view/Library/EcuSensors A fairly good list of Japanese car's ECU pin outs http://www.plxdevices.com/ecudatabase.htm USB to RS232 converter chips http://www.ftdichip.com/
