First start-up
Hello
Im about to startup my new freshbuild engine ( se signature for spec ).
I got new 30# injectors.
I worried that the car will run to rich and clean the cylinderwall with fuel ( not a good thing during break-in).
I know that I have to change the injector constant in the chip for the new injectors. But im still worried that it will run to rich before i get the BLMs sorted.
So my question is this, is it "ok" to change the injector cosntant to , lets say 32# to be "sure" you will be running a bit lean instead of rich?
Just for the first couple of scans so know where im at. Then I will change back to 30# and adjust the BLMS.
Or perhaps i just worries to much
Thanks

On first start up, I'd prefer to err on the side of being rich, rather than lean. Set the injector constant to 30 lbs and work from there. After you fire it up and run it for a few minutes, check the plugs to see how rich (or lean) it is running at that point.
