Biggest problem I have with the pfc is no altitude compensation map and the temperature correction sucks.

 

Why doess the e11 (I think) use the Halwin software when it only controls fuel??

 

yes that is a function I really like about the haltech. the baro correction and the temp correction function. saves you from having to re adjust everytime you go up or down 500 ft or so..I'm not sure how it will do with my altitude range. it goes from around 4700ft to 8200 ft with in a space of few miles.
