using a injector for tach will only give u 1 cylinder and there will may not be enough pulses this will likely result in an over cranking or under cranking situation.The microprocessor cannot discriminate between what is electronic data and what is a true pulse feed from the motor.

High horsepower boosted cars often need large injectors. Most large capacity injectors are available in peak and hold form - about 2 ohms impedance, whereas most stock injectors from about 92 on are saturated (8-10 ohms impedance). Honda engine computers require a total injector impedance of about 10 ohms so a resistor pack is needed whenever the stock saturated injectors are swapped with peak and hold.

Early model injected Hondas; 90-95 Prelude and Accord; 89-91 JDM B16A Hondas all ran external resistor packs with low impedance injectors.

not sure what your getting at.

but as for the forst bit i know you will be getting a reading of 1 cylinder. most alarms you have to learn the tach before you can remote start so it won't matter. once its getting the ac voltage that it learned
