Summary of change:
'''Oskar Nilssons Audi S4''' '''Technical data''' Audi S4 2,2t -92, AAN-engine without modifications so far, VEMS v.3.3 with Motronic connector, box no. 1045 '''Status''' Collecting information about firmware version to use and proper configuration. Jörgen has delivered the hardware, a Genboard with Motronic connector. The unit was pre-built in Hungary and updated by Jörgen to latest standard. '''Software configuration''' What exact firmware version is the proper one to use? ** Seems 1.1.27 is the latest stable version to use (as of 2008-03-12). I have config/tables from Jörgen: ** http://www.vems.hu/files/MembersPage/MattiasSandgren/OskarNilssonsAudiSFour/jorgen ** Awaiting evaluation An MSQ from an RS2 from one of the Finnish guys: ** http://www.vems.hu/files/MembersPage/MattiasSandgren/OskarNilssonsAudiSFour/rs2 ** The lambda table uses AFR (In my opinion wrong) and the spark map seems to use (too) high advance on load. Miska Peippo sent an MSQ for AAN using firmware 1.1.27: ** http://www.vems.hu/files/MembersPage/MattiasSandgren/OskarNilssonsAudiSFour/mpeippo ** Very nice config with boost control and idle air valve control I will evaluate these and assemble a "best of" configuration/tables setup. With some documentation I hope these can be pre-loaded in the pnp Audi boxes delivered. '''Deviations''' In the majority of installations it's very probable that the stock IAT sensor which is of PTC type will be replaced by the web shop IAT that uses standard NTC type. This requires changing the on-board pull-up on the analog input for the IAT back to the standard 2.7K. This makes the installation less pnp but everyone seems to agree that the stock PTC can be replaced with favourable gains in response and accuracy.
