                        i do it for me to learn these tables better to use. So the table you did is realy rich, its realy good but i optimized for idle revs to get 0.95 lamda.
                        And ive send you an email

                          0.95 is rich at idle....try the Config #3 out and send me a log.

                            So i did little boost 0,5, 0,7 bar. i had little problem at the idle i must change the value from the injector to 3.8 ms. With 3.1 my lamda and ignition fluctuate


                            With 3.1

                              no man, change it to 3.1 again. It is too rich now. You need lambda 1 at idle. For 630 Siemens injectors you have to use approx 3.1. You have to scale the whole VE table down. Tell me what Fuel pressure regulator you are using (pressure).

                              If you like send me the log.
