Problem
I have taken back a customer's ECU number 328 to sort the Aref issue. 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.

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

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.
