This also takes into consideration the resistance in the vehicle's wiring harness and the injector driver circuits etc. Constants are unique to a particular car.

Anybody else try those offsets lately? Anybody had them not work?

Cool. Injectors (along with LE3 heads) go on this weekend....

Re: delphi/lucas inj offset vs volts (where can i get it)

Guys,

I've noticed the voltage cells in TunerCat are a little different than those listed in the link.

1 question about the celled units. TunerCat uses units expressed as usec, but the link above represents numbers differently. An example would be @ 0.00 volts "305" vs. the link's units @ 0.00 "0.23".

I am guessing by looking at the numbers, I should be multiplying those offsets by 1000 so they are reflected as the proper units. Am I right on this?

That's what I'm ***uming--milisecond vs. microsecond, multiply by 1000.

I tried entering those offsets but the maximum allowable value in Tunercat is 7782.

Who has entered these offsets using Tunercat?

Then just put in 7782. Thats what I did for mine. How many times do you drive your car under 6 Volts. My guess is NEVER!
