What changes do you need to do if any after intalling medium to big cams like the Kelford 272. They usually take less timing specially during boost and high rpms. But what about the cruising part of the timing map. I mean areas lower than 120 load on the map. Do they need big changes? Right now I am running them almost stock except higher timing at idle (maybe too high because I sometimes get a P0300) and some changes in the spooling area. Anyone?

 

The 8 roms had a bug in the code for the P0300 CEL.

Did you throw this CEL before your cams as well or just after?

 

The amount of timing you run will depend on your car and your setup. Dyno time is the best way to find the best combo.

 

No code ever before the cams. The code started after I installed the cams. I am also running 9* at idle so I am not sure if it is too high. I started with 10* got the P0300 now at 9* I am also throwing the code.
