Title: VAG 1.8t AEB Injector Opening Time
Post by: Jim_W on January 31, 2011, 12:34:10 AM
Anyone have good injector latency (Injector open time @ 13.2V) settings for VAG 1.8t AEB injectors?  Bosch part number 280 150 447, 210cc/min.

Thanks

look here. http://www.usrallyteam.com/content/products/injector/Bosch_Injector_data.xls
with no lag in 2.5ms it would inject 7mg in 2.5ms
practically - 5.63mg

5.63mg relates for 2.011ms if lag is subtracted.
So lag time becomes 2.5-2.011=489us
But: it is 1) for 300KPa 2)for unknown (I suppose higher) flyback voltage. 3) unknown voltage

Excellent.  Thanks.

How did you find the 2.011ms and 7mg figure?  Are there better descriptions of of the column titles anywhere?  What is "g/1000 Imp."?  Grams per thousand... what?

This is a good starting point even though I'll be turning the pressure up to 4 bar.

Grams per 1000x2.5ms pulses.
I calculated static grams per 1000x2.5ms=2.5s. And so find dead time. But it is just for reference.
