Starting inlet cam at minus 10

[white_twin_cam]

I have tried searching for this but havent been able to find answer so apologies if it has been answered somewhere else.

I have checked my build valve clearances and know that the maximum cam timing I can safely run is 40 degrees (20 at cam). I know other builders who remove the inlet camshaft keyway and secure the camshaft back 10 degrees (5 at camshaft) so thst max travel is effectively -10 to 40 degrees. They use stand alone management systems. I know this might make engine starting a little harder.

My question is, if I build my engine this way will kpro throw a camshaft timing fault code and is there a way to override this? If not I can buy a pulley that only goes to 40 degrees but obviously would rather not.

Thanks for your help.

I checked through Kpro manager screens and it looks like on Vtec parameters page I can disable P0341 to get it to work. Anyone know of any other codes I could throw? Will a target vtec angle of 0 deg actually be 0 or will it take the -10 as 0?

"P0341 This error is generated if the phase difference between the intake and exhaust cams is more than about 5 degrees. Some after market camshafts will generate this error"

Thanks

I definitely would not recommend offsetting the cam and disabling the error. Using a VTC with a stop is the right way to do this.
