for a power fc or similiar.
the interesting thing is, I'm nearly sorted for removing the AFM and just running the car from the TPS, and that's on a standard ecu, runs well too, still some little bits to iron out.
the standard ecu is unlimited really in its potential, the only disadvantage really i can see is expandability, things like anti-lag, extra injectors are really a no-no on the standard ecu.
thing that always concerns me with piggy-back units is the fundamental idea of altering the stock ecu externally, i know it works okay, but it still seems "crude", but i can't deny the figures on paper. as an example the k11 ecu doesn't only use the maf reading for a simple load calculation, it references it many times, something most other Nissan ecu's don't, i personally would be concerned about removing the value with an outside source.
if seen some odd readings and results when looking at piggy-backs, which is what puts me off, if your getting good power, and reliabilty though - more power to your elbow as they say.
if it was me, it'd be stand-alone every time, power fc, omex, if you must go e-manage, make your the mapper has experience with piggy-backs, would be my advice.
