Re: tbi injector offset values

Not sure how easy it will be getting those values for 5.0l x-fire setup. I have a few x-fire BINs but no definition file for them.

In the TBI ECMs such as the '7747 & '8746, there is a single offset value. Which for a 5.0l engine (55 #/hr) the value is 396.76 usec.

There is also a PW multiplier table versus voltage.
