P28 S300 - ECU voltage detection problem

Post by Lyle_57IAL »

Hey Hondata,

Currently have P28 S300 on a B18C Turbo Integra Dc2. Currently the ECU will not see the correct amount of voltage being produced from the battery. The floating battery voltage is around 13v as you would expected however the ECU sees this as 6.0v - and hense is messing with the injector Dead Times.

What could the possible route cause be forthis - what components (either ECU, alternator or Battery) should we be looking at etc

Cheers

Lyle

When you measure the voltage at the ECU pins with a multimeter, what voltage do you see.

Voltage going into the ECU is as expected. 13.5v or there abouts.

Post your calibration as well as a datalog showing the issue.
