diagnostic tool

[Wen Yen Chan]

I have just finished designing and constructing a multi-chan. electronic 
data logger which might be useful for field testing EFI systems. The 
logger has eight analog inputs which it samples between 3 and 250 times a 
second (user set rate). The acquired data is stored in a 128k SRAM which 
can be later read by plugging the unit into the parallel port of a PC. 
The parts needed to build the unit total to less than $40 cnd. ($30 US). 
If there is any interest in the designs I will try to make them available 
online.
