Default info on new generation of ecu's

Check out the Sept issue of HOT ROD MAGAZINE. Under the article on the neon srt-4 there is a sidebar on the engine computer. Very informative and may explain why it will take a long time for tuners to mod the STI ecu.

Would it be possible for you to provide the text of the sidebar... or paraphrase it?

Hot Rod isn't in my stable of mags...

DaimlerChrysler's Next Generation Controller algorithms are ' model-based ' vs pre-programed tables of operating conditions. An air charge temp sensor after the intercooler and a throttle inlet pressure sensor can predict turbo compressor speed and pressure drop across the throttle blades and the AIC. The wastegate control is dictated by throttle demand vs a BOV at a set boost pressure. " It's this combination of information that has been giving fits to aftermarket companies trying to modify the Mopars with electronic throttle control. " The above are some highlights from the article. Mopar already has a stage I kit with a computer module and four fuel injectors for under $500. I know a Mopar is not a subie, but this might possibly give some insight on what's going on in our ECU's.
