	Bosch 630cc 0280158123 dead time lag time S3 1.8T BAM « on: December 21, 2022, 12:42:49 PM »

Hi,

im looking for 3 bar (stock FPR, 1.8T BAM) dead times for bosch 630cc injectors. i bought used injectors without documentation and i cant find them in google, really.
i calculated KRKTE via S4Wiki (thanks god Nyet wrote s4wiki) but still i cant find TVUB for my injectors.

best regards

Why 3.0bar? just use 3.8bar fpr and use values from porsche ME7

these values are quite decent

Bosch EV14 - 0280158123

Deadtimes @ 3bar

8V - 1,73ms
10V - 1,08ms
12V - 0,75ms
14V - 0,5ms
16V - 0,3ms

to buy used injectors is always risky,
better get them checked by professional shop

if you buy them from finjector, deadtimes are part of attached datasheet

i know but i bought them as a used part. my friend used them for 1-2month and he cant find documentation. i checked injector on the test mashine and they are fine, but im still missing properly values for stock 3bar FPR. values which you gave me are weird. my car is running on idle etc. with +15-25% lambda control. idk what im doing wrong

How's your KRKTE, for different injectors start with FKKVS set to 1.00 all over.
You need more measurement values to get other possible causes too (battery voltage, air mass, etc.),
use e.g. me7logger

my KRKTE is 0,05117 calculated with KRKTE calc. i really forget about FKKVS. i will set it to 1.00 and try again. other possible causes aren't possible, they are new or checked 10x times.
best regards.

edit: TEMIN/VA is still default, i mean 0.749. idk should i change it or not. KVB is 627, it's good value or no? thanks

yes, TEMIN/KVB are fine,
tweak KRKTE for bigger steps (deviations > 5%),
FKKVS is for finetuning all over the te range,
therefore I recommend ME7logger
