mpgguino problem

[user102]

Hi I have a mpgguino installed on a civic ek3 1.5l from Europe but I am getting problems with the readout.

1. Despite several calibrations after 1500 miles the vss/mile is either to low or to high and is consistently at least 20 % off the odometer reading.

2. Microsecond/gallon is a bit more accurate but Is still a challenge to get it within 10 % of the pump gallons because its either to high or to low.


Any suggestions ?
