Right need some help I've have built my engine up and i have fired it up for the first time today and it lives

it's a fully forged engine with td05-20g, fmic, b44 fuel pump, 850cc injectors, mocal oil cooler, and a few other supporting mods

my questions is can I have the engine mapped with the 850cc injectors to run the car in. Or do I have to run it with the standard ecu and injectors?

Thanks TMP

 

You can do both to a degree, but as it's a fresh build I would suggest running your standard ecu and injectors for the first 50 miles with no boost just to make sure everything is in correct order, no leaks ect ect. Then have the car mapped correctly for the run in period as it must see progressive loading and boost to bed the engine in correctly.

 

either injectors will be fine on a running in map.


search around for methods of running in as they vary a lot. (I prefer the harder/quicker running in method)
