Peak and hold conversion

[Phil Lamovie]

Hi Scott et al,

The solution is exceptionally simple.

Purchase motorola or similar P/H chip. Drive it with original darlington
output with maybe a 1k to pull it high.

Total cost for 4 cylinder engine is approx. $20  AUS for two low current
injectors
on each of two drivers (approx. 4 amps available).

All the smarts are in the chips including a 4:1 ratio of peak to hold
current.

End of problem.
