News 2007.01.21 Still couldn't get reasonable control over injectors. With normal values of inj opening I can't get normal idle. At a bit higher RPM, VE table needs to fall below idle area. It started to show somewhat good idle when I changed injopen to 400-800us, rampup to 2000-2400us. No need to say this made low loadsites(60-80kPa) to be pig rich because it can't give narrow pulses at all then. Interestingly higher loadsites (100-120kPa) were also disrespecting VE table at all, I could change VE from 30% to 255% without significant change in lambda value. In fact the only thing really changed behavior (and lambda) was the injector opening settings and req_fuel. I even wonder how the car's operating so smoothly with an untunable VE table.

It wobbles between 500-1500 rpm rapidly or stumbling around at 800 rpm -no matter how much air is allowed (via MDI commands). It changes between these behaviors without any change in config. **This behavior is cured by now. It needed ignition based idle to be turned ON, and everything was changed immediately. |
