Title: Can we edit system constants? Post by: Snow Trooper on April 08, 2012, 07:33:14 PM There are a number of them i would like to play with, I believe from reading the FR that our ecus are much more configurable then most of us know. Things like mono exh path/ dual bank control and wideband may be possible if I am reading correctly. My searching and reading and comparing bins has turned up nothing with regards to editing these.
a few i am interested in currently: SY STERVK PROKON EIN system constant condition: stereo exhaust system upstream of cat SY STETLR PROKON EIN System constant condition continuous Lambda control present SY_NWS PROKONAL A System constant cam timing: no, 2-pt. or continuous SY_ZYLZA PROKONAL A System constant number of cylinders (what if we could retune me7.5 ecus to be 2.7t compatible, all the hard maps would cross over) plus many more... Title: Re: Can we edit system constants? Post by: ArgDub on April 08, 2012, 09:46:41 PM Its not possible unless you have the source code. SYs are evaluated at compiling time and unused code is removed.

System constants correspond to a particular set of hardware configuration, you cant simply change them. Title: Re: Can we edit system constants? Post by: britishturbo on August 06, 2013, 07:31:25 AM They are compile time variables.
The compiler uses them to decide what sections of code to include... The first 3 things you mentioned though are easy to work around :-) Title: Re: Can we edit system constants? Post by: Snow Trooper on August 07, 2013, 10:10:57 AM This is a very old thread. People made work arounds for everything mentioned since.

I wonder who we could bribe to get a pre-compiled program ha.Title: Re: Can we edit system constants? Post by: savages4 on August 11, 2013, 07:38:20 PM So what work arounds have people done to enable wideband support on me7?
Title: Re: Can we edit system constants? Post by: Snow Trooper on August 12, 2013, 08:20:18 PM Emulated data from aftermarket widebands or direct feed with code changes. No one has ported over me7.5 to my knowledge though.
