FlashPro questions & answers specific to the 2006-2011 Americas Civic Si

hello, I recently installed a set of skunk2 stage 2 tuner cams on my 08 si and i was wondering if the startup basemap that is provided in the flashpro is based off the stock block (stock pistons)? I saw that it runs 45* cam angle and wanted to be certain that it is safe to run the basemap for the time being.
I believe that it was on a stock bottom end. As with any basemap you will have to check your AF ratio and make sure you are not getting any detonation.
IF there is the possibility of valve to piston contact you need to measure that before assembly and use a cam gear that is pinned to not go past that safe value. Relying on the ECU alone to control that is not a good idea.
Thats why i asked if the stock was used. The cam angle map in that particular kal provided in the software has the vtc advanced up to 45* which realistically is all the cam rotates. On the skunk2 website they recommend up to 40* for max power. So if the basemap is based off a stock block then in my opinion it would be safe to run the 40*. I know there are variables when it come to production engines, but i dont think they vary by much.
It does not matter what the calibration uses - cams must use a physical stop in the VTC to limit advance to prevent valve to piston contact. The VTC control is only a closed loop control using engine oil pressure, and there are many factors which will let it over advance briefly. Plus, the ECU runs through a VTC cleaning cycle at least once per drive which goes to full advance.
