misk Posted March 11, 2020 Share Posted March 11, 2020 bit of a long shot...just curious if anyone has come across a setting for TDC offset for the notch in the crank trigger. i6 is 60*btdc v8 is 90*btdc so kinda figured there'd be something somewhere. cheers Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted March 11, 2020 Share Posted March 11, 2020 There are a few that are different auF11468 CAM offset with respect to engine pip. auF1217 Number of PIP's per engine revolution_ 2 -> 4 cylinder (2 PIP/REV) _ 3 -> 6 cyli There are some other hard coded variables such as: Top dead centre angle: 60 for 6 cyl 50 for the 5.0L v8, unsure about the 5.4 Degrees per tooth: 720 / 36 Number of teeth: 36 Number of cylinders: 6/8 These are similar to the TMAP slopes in that they are not scalars but rather hard coded into the assembly. We could map these but it would be a fair bit of work. Any reason you want to modify these? Quote Link to comment Share on other sites More sharing options...
misk Posted March 12, 2020 Author Share Posted March 12, 2020 im looking at running a tb45 off the barra pcm, would make lining up the crank timing a much easier process if i could at least edit the tdc angle Quote Link to comment Share on other sites More sharing options...
