I'm new to Audi's and I did a search so flame on if I'm blind and/or stupid.

Is there a reflash option for ECU tuning for the S4 (B5)? For the EJ20/25 series of engines in the Subaru's you can get an ECUTek custom dyno-tune for your ECU. As you progress in mods you can get it retuned. Is there such an option for the S4, or am I going to have to settle for an off-the-shelf map on a chip or go all-out and get a stand-alone EMS?

Thanks.

 

not really.. you need a new chip...some of the model chips like apr i believe you can reflash those..just not the stock ecu. I believe

 

EPL and Autospeed are two that will do custom software for you, in addition to a few others. This is ofcourse a little more expensive than off the shelf software. Depending what your plans are it may be it may be better to go with off the shelf software until you are full stage 3 with some more unique upgrades.

 

Get the off the shelf flash. Learn about the ECU, then download Lemi, it will let you tweak the ECU's settings.
But honestly, OTS flash is really good, the ECU in the Audi is SO much more advanced then the Scubi. The ecu also has a lot of stock adaptations.

Really people don't mess with the software much until they go STG III with K04's & fueling.
