My cam is Lingenfelters #74216 specs are 213/219 duration @ .050 .493"/.502". I'm running an 89 style MAF ecm and I am curious to what I'll need tune for this cam. I know I need to set the minimum idle to 750 and get full spark advance in a little sooner but will I have to modify the fueling tables? The motor will have ported stock heads on it, long tube headers, and close to stock compression ratio. Thanks in advance everyone.

 

The MAF is pretty much independant of the engines configuration (well, almost). Shouldnt need to do much to the MAF tables. Depending on the cam, changing the filtering can help smooth out the motor at low loads, but theres only one MAF filtering constant for all flows in the stock ecms, so its a balance between filtering the signal and still having good response. If your using differnet injectors, or fuel pressures, then the injector constant will have to be adjusted. But thats about it.

 

Thanks for your response, that's what I was hoping to hear.
