[Diy_efi] Stepper Motor to drive mechaical speedo

[Steven Donegan]

Yea, 1% is too far off for my hobby :-) 2nd place (first looser) can be measured in a small number of feet at say 100 mph (100 mph = 146 feet/second)...

I'd go DC with pwm. I suspect you can get within 5% which should be good enough for daily driving...but not for rally nutz like steve ?:-)

My reason for wanting to keep the original speedo in place is just that, I
want the car to look original.

Thanks
