Cranking Coil Time Multiplier

[Wez]

Hey All,

I have a quick question regarding coil charge time and the cranking time multiplier. On my setup I have 0 multiplier and 2.0 right across the volt range, on another setup the cranking multiplier is 1.250 and 1.9 across the volt range, does this work out like this for actual cranking charge time :-

My Setup: 2.0 x 1.0 = 2.000
Other Setup 1.9 x 1.250 = 2.375

Both motors are running the same coils and ignitor but my car always seems a little lazy to start when cold.

Thanks

The Coil Charge Time is the Dwell time for the coils. This varies based on Battery voltage but on the Base Cal for the supra this is set at 2ms across the range and really should be updated to all the voltage range which i will get on asap.

The cranking multiplier should be set at 1.250 for your engine but being yours was the first 2jz running an s6 it was probably missed at intial calibration.

If the cold starting is lazy then change this and add some more fuel on the Preliminary Fuel Injection
