I have the blue cat stuff for tuning virtual ve but am still not understanding how I am going to tune timing. Since the timing tables are most defanitly going to be maxed out with 10psi . so does anyone know which direction to point me in. I'm new to the whole tuning vve I'm use to a map x rpm timing table. Thanks!

You tune up to the airmass limit the ECU has. Past the official limit, the ECU will just use the max value. So if the limit is 1.2g, and the value for it is 15*, it will keep using that 15* even if you go up to 1.7g or something. Plan accordingly.

Thanks redhardsupra !! Hopefully by the time I get ready to tune it hptuners will have their version ready so I can use one software

All you have to do is change the spark airflow axis. I run 20psi on e85 with a e67 ecu and my timing table goes to 2.30. Do a log and see what your your air flow is at 100 kpa then at 168 kpa 10psi. put that airflow value as your last row and interpolate between 100 and 168kpa.

make sense?
