	Data logging / injector headroom « on: June 06, 2020, 03:18:57 PM »

What else do i monitor in me7logger to work out how much headroom i have left in my injectors?

Just monitoring 02 / wideband lamba values doesnt tell me how much further i can push my engine.

BJX engine with 06a906032QN ecu

Has the usual deletes, ko3s turbo, 2.5" downpipe and decat exhaust, large FMIC, 3" TIP, Forged rods.

Still has standard injectors, pistons, valves and MAF.

Logging 02 and lamda only tells me once the injectors cannot supply enough fuel.

What other varibles can i log to work out how much capacity the injectors have left?

I literally posted the list. Why be selective? Just log all of it.

There is no injector duty cycle variable. It is caclulated by ECUxPlot using ti*RPM/2 IIRC
