So I replaced my old 1300cc secondary injectors with some minty fresh stock 850s. Mostly for smog but also because the 1300s were leaking after the car sat for a couple of years unused.
Will the tune safely work if I were to revise the injector config to 850cc? Or do I need a full on retune?
Retune is scheduled for end of January. I'd like to drive sooner if it is safe.
Thanks.

 

Use the PFC Commander to change the injector size. You will need the DATALOGIT hardware/software if the lag values were changed when the 1300s were installed.
Retune the map. OR: If your engine is stock, reload the stock map.

If you do not know how to do this, find a PFC tuner.

This should have been posted in the Power FC forum.

 

Thanks, Chuck. Had forgotten about the lag settings. It has been 10+ years since I looked at your notes or touched any PFC settings.

What should the lag settings be for stock 850cc secondaries?
