so my 1300cc secondaries actually flowed 1600cc. I have had the 1300s for close to two years and never had a problem with them. I dont see this as a problem either. However, If I have had my secondaries set as 1300s in the PFC, would that cause the injectors to spray more fuel than the ecu is telling it to?

Is it ok to set my secondaries to 1600 on the PFC now that I actually know what they flow?

Should the injector settings be about the same as with the top feed 1600s?

BTW, I have always had a very rich secondary injector transition.

 

I can set up a PFC badly but tune it to run great. The if I only correct the few entered bad values without retuning, it then will run like crap.


This is one you should be able to determine by basic reasoning of what the PFC is doing.

If not then by comparative reasoning to something similar like pouring water through two funnels both which you are told have the same size hole but one is actually larger. Test both and lie to yourself about the hole sizes (both ways) and what the tests would show.

Have you ever worked on carbs?


To be a good mechanic requires more than tool use knowledge, problem solving ability with logital testing is most important.

 

I also found this exact same thing when I got my injectors serviced. They flowed something like 1560 cc I think. I assume the only effect would be that the engine runs richer with the PFC configured for 1300s, but I would be interested to hear whether there is any danger to running injectors that have been bored out such that they are putting out nearly twice their design capacity. They performed perfectly well during the testing, so I'm not terribly concerned yet. Anybody have any idea where these misnamed 1300cc injectors came from?

 

I have not worked on a carb. The way you explained it is pretty much exactly the way I thought of it. just another useless post by me.
