EMU:injector lag time + map advice - Subaru Impreza GC8 & RS Forum & Community: RS25.com

Finally got a wideband hooked up to the Emanage Ultimate and want to learn to map it (conservatively of course)

What is the injector lag time for stock RS injectors ? (I'm assuming they are also 280cc ?)

Any advice for tuning the AFR's much appreciated !

I know nothing of tuning, but stock RS injectors are 380ccs.

Thx, should be the same as the WRX's.
(my car was a NA EJ20, my injectors are 280cc, but lag time
should be close, if not equal.)

The latency is not large enough to be of any concern when building a base map to get the car to run. As for advice on building the map....look around onlyine for people who might have a decent basemap to get the running and do a dyno. Stay out of boost until then.

I am almost positive they are 280cc
