Part 13 : Stand-alone ECU swap!!
Because we modified stock i-ETAS to work only by cable, the Altezza ECU seems to keep learning the difference between TPS sensor and Accelerator sensor.
It caused some dramatic ignition timing changes over time, making car run poor as time goes.
So we believed it's time to go with stand-alone ECU.
Because of its cost and flexibility, we decided to go with universal stand-alone AEM EMS-4.
I also never liked the idea of running both ECU(stock and AEM EMS-4), we have made AEM EMS-4 to work truly stand-alone.
A/C and Dual VVT-i were also being controlled by the AEM EMS-4.
Bye bye stock ECU!! (another weight savings!!! HAHA!!)
It does take some good amount of times and parts to make it wok...
I will post up the results(possibly some good dyno graphs) once I finalize the tune!!!
