That is race car stuff.for a street car I would keep overlap under 12 degrees on a DI motor and under 8 degrees on a PI motor. The apps are pretty interchangeable in form and function. Flycut is based on another open-source clipboard manager called Jumpcut, which also doesn't copy or cut images or tables. Non-developers can use it too, but the app isn't designed for copying images or tables. I certainly wouldn't expect a cam with 21 degrees of overlap to behave like stock. Flycut is an open-source clipboard manager designed specifically for developers. There becomes a point when you introduce enough overlap into the system, you will get some odd behavior that you didn't have when stock. I agree it's likely tuning related and not mechanical, However the GPI stage 4 has A LOT more Overlap then a TSP VVT3. I tried launching from the command line and it said I had to give permission in access controls again, but doing that did not fix the problem. Need to make sure that if your tuner left dymanic airflow enabled he tuned the VE correctly. Launching Flycut doesn't appear to open the app.I deleted it and re-installed, but that didn't appear to change anything. I start at 1300 rpm and go down to 850 rpm after 60s in a linear way.Īfter that it could be your virtual torque table off around idle for certain airmass (more airmass engine cold). If your rpm setpoint cold engine is at 800-900 rpm it is going to surge a lot.

GPI stage 4 with milled head and no fly cutting must be really close.ĭoes your engine start right away cold ? When I first tuned my cam I had to bump my cranking airmass a lot and of course adjust my rpm setpoint from cold to hot engine.
