BMW M54B30 injector latency / dead time

Recommended Posts

Hi guys, am having issues with a modified M54B30 running on a G4+ E36 ecu. Engine changes are Vanos delete with cams locked at 0º advance, M50B25 intake, ICV & throttle body, M43B19 VR block mounted type crank sensor, M50B25 intake cam sensor, AFM & charcoal canister delete. Cams & injectors are factory.

Am looking for a latency table to suit. So far the only numbers I've come across are here :775774949_injectorlatency.thumb.jpg.e1859ce733a51f7c6f4aea8e55b29905.jpg

 but I'm not 100% convinced they're accurate. Also, as there are no published values for 7,9,11,13 & 15v I've used the midway point as a guesstimate. Is this regarded as acceptable?IMG_2114.thumb.JPG.bfd4b46ae957f6bacc43a3ef8d3f130d.JPG

 

 

 Could anyone please share the numbers they've used?

This is the first time I've taken on a project like this, your advice & patience are appreciated!
