Thank for purchasing an Acewell ATV/Motorcycle/Scooter computer. This
manual is specially designed for the ACE-27xx/28xx series. Each model has 4-6
LED indicators. Different models have different LED indicators; a fuel meter is
optional, but all other functions are the same. You may find that the photo above
has a set of LED indicators different from your computer; the photo is for
reference only.

2. Digital tachometer displays up to 19,900 RPM.
3. Tachometer signal picked up from either CDI or Ignition coil.
Shift Warning RPM
1. Function enables you to set up an RPM shift warning.
2. Bar-graphic tachometer flashes when RPM reaches pre-set value, and stops
flashing after you shift gear.
MAX RPM: Maximum Tachometer
1. MAX RPM is displayed on 2nd row.
2. Displays highest tachometer reading achieved after last RESET operation.
SPD: Speed Meter

RPM-INPUT
Either One
2-5 Turns
1. Signal intensity from ignition coli
is dependent on vehicle type.
2. Circles 2-5 turns around ignition coil,
with more turns creating steadily signal,
fewer turns creating weaker signal.
3. The computer can use all type of ignition
system, only if the RPM is not stable you
must sometimes add the attached 1MOhm
resistor in the wire of the RPM input.
