Does anyone know if the standard M35 ECU can 'learn'?
After I changed the exhaust and dump I saw a massive increase in performance. On the dyno it looked to be 30kW and an extra 3PSI boost. Turbo starts to spool up now at around 2250rpm.
Then I fitted the pod, and on the Informeter saw I was running the injectors at 100% by about 6000rpm.
Then I fitted the HDI intercooler, and it seemed like it lost a bit, spooled up later, and was a bit more sluggish. I figured this was the lag introduced by having a bigger intercooler to fill.
Then I dumped the Valvoline oil, replaced it with Motul 300v, drove the car around 300km, and then let the car sit in the driveway for about 10 days.
Driving it on the weekend, it appears that the injectors are no longer hitting 100%, and the turbo is starting to spool at 2250. Sluggishness seems to have gone away, and it feels as good as it used to.
Would this be the ECU reacting to the mods, and relearning/retuning itself? Or would it be something else?
