tcsim,
i dun think its called 2 mapping. What happen is there is 2 setting map. 1set of mapping is based on closed loop, whr you do ur cruising and normal driving (to some plp, normal driving is extreme driving). Thn once your throttle load exceed certain percentage, thn it will jump automactically into 2nd set of the mapping which we called open loop. You can set the throttle load percentage on whn to switch frm closed loop to open loop. Thats all. That why u see on SAFC it mentioned 16 points x 2 mapping.
you can refer to the back post, which i explained in breif on diff between emanage and SAFC
as i mentioned in earlier post, installing emanage required some tricks and tips. not just anyhow wired. Thats why u see normally plp charge slightly more thn installing SAFC.
