Dual channel knock sensor interface
5.89EUR
TPIC8101DW. Dual-channel acoustic knock sensor interface chip for genboard v3.x (onboard place for it, easy to solderon).
Useful to retard spark in case of detonation (caused by too much advance).
Probably useless for most industrial applications of genboard v3.x
Also not much use if unable to mount acoustic knock-sensor to the engine block.
