Using edit after changing fuel injectors Alright, thanks for any help. I am upgrading to 36 lb injectors, and I have been playing with edit, but I am not sure what to change. I know I have to change the injector flow table, and I know what I am doing there, but do I have to do anything with the injector offset, and what is injector offset anyway?
Thanks for your time

Re: Using edit after changing fuel injectors My short answer is:
If your MAF is stock, stay away from the MAF table and Injector Offset and use the Injector Flow Rate table. Your reported MAF data will be incorrect for other PCM calculations if you change the MAF table.
You can decrease the Injector Flow Rates by a certain percentage to take Ltrims more negative, or increase IFR values to make them mroe positive.
My long answer, with other guys' questions, is here:

Good luck!

Re: Using edit after changing fuel injectors My understanding of injector offset, is that it just takes into account how quickly the valve opens(well actually its probably the time to get to a certain percentage of open). Every injector type is a little different but the data is hard to get.
