PFC Injector settings

[grepin]

Just wondering if it matters what the PFC injector settings are set at with Sard 550cc injectors. Mine are all still set at 100% and 0 msec. Its for closed loop operation I believe. What are other people setting theirs at with similar injectors.

Steve if your out there you may be able to help.

According to my calculation's

550cc x 67.5% = 370cc which is what the stock injectors are. - I think thats around what steve is running

So set them at 67.5% and the ms is lag time so good place to start would be 0.8ms

What would the significance of leaving them set as is now. 100% and 0ms

[cameron]

Yep with stock injectors just leave them at 100% and 0ms.

Sorry didnt elaborate enough. I have Sard 550cc fitted now with 100% and 0ms. What is this doing compared to setting it up at 67% and 0.8ms?

Cheers

This % setting is used in closed loop mode, cold starts etc. So the computer doesnt dump heaps of fuel in or cut the fuel when the functions are operating.

The setting in ms is used for lag adjustments, This is also used to make sure the injector is syncronised to open at the right time.

By adjusting the ms setting it can also get rid of hunting on idle,

Other than that try it and see if it makes any difference. - You might need to increase or decrease by a couple % to get it best for your car.

Hope that helps,
