Injector Offset & Multiplyer - What does it adjust?

Post by JohnDee68 »

Hi guys,
There are three tables and a Scalar which are labelled

1. Injector - Offset Vs Battery Voltage (msec units).
2. Injector - Low pulse width Offset Vs Base pulse width.(msec units).
3. Injector - Multiplier Vs RPM & Cylair.
4. Injector - Fuel Boundry Located this CAL after 3X REF. (Scalar).

I was wondering what is actually being altered by these tables. are they adjusting the injector Pulse Width ?
What is the Scalar table actually for and what does that adjust ?

Does anyone actually have a BOSCH injector data specs sheet for the 0280 155 777 Injectors That I could get a copy of by any chance?

I know from experimenting on mine that if I make injector offset vs battery voltage lager car runs richer and smaller car runs leaner

A cars voltage fluctuates so there needs to be a table to compensate and adjust the opening time to maintain stable AFR's.

Yep. 1 and 2 is to charicterise the opening times of the injector against those to factors that make it fluctuate (1) and non-linear (2). (3) is more general purposes. (4) I am not sure, but it sounds like an internal value relating to how other tables function. I would not touch that one.
