^^ Hmmmm... alto doesn't have ECU.
atleast any digital RPM available in market? coz i need it so much...
I normally drive on low revs, so due to music playing loud in car and windows closed, i cant hear engine responce to shift gear...and it varies with A/C on/off... so in order to monitor right RPM for gear shift, i need it. which wud obviously save my fuel too...
But i hate those cup size RPM meters in market with glowing red needle
