Hi What cards do you need to pay attention to? on warm there is a problem with starting, it takes a very long time to start. everything is good on the cold, right after the stop it starts up well too. but some time after the stop I spin the starter for a very long time. thank.
How did you fix your warm start problem? I have same problem. If i leave overnight starts right up. Shut off and restart no problem ether. But if i go to store for 30-45 min takes 5-8 sec cranking before the car starts.

Hello my problem was most likely associated with the nozzle which was not tight. until I switched to stock. after cleaning in ultra sound and checking at the stand I will tune for a new one. I think the problems with starting and skipping at idle were due precisely to this.

here's the theoretical way to calculate krkte straight from some bosch manual: all of the q-stat values in the above excel sheet are calculated for 300 kilopascals which is 43.5 psi. to convert the operating pressure to what a standard b5 s4 would use, we need it for 4-bar, which is 58.0 psi. to do the conversion: q-stat * sqrt(58.0/43.5) ==q-stat @ 300kPa * 1.1547 for my application = 532 * 1.1547 = 614 cc/min that's 614 cc/min of n-heptane... ml/min or g/per min ? on this qstat@300kpa X 1.1547

anyone tested such injectors? BOSCH 0 280 158 235 --> 750cc or 500g/m look like good alternative for 0 280 158 123

I use these all the time. Had a set on my 1.8T, just put a set into my S4. Have about a dozen clients running them because they were on sale on FCP euro. Good injectors. I posted specs on this very thread a page or two back

Thanks for posting this, those are 35$ each in local shop while 630cc ~55$ so price wise very attractive. If you used them successfully I think I will give them a shot

was hoping for spray pattern specs etc. so I can add it to https://s4wiki.com/wiki/Fuel_injectorsthough a TVUB/KRKTE table would be really nice as well on that wiki page.

whats the connector type? I got lost a bit.. 0 280 158 123 - 630cc --> EV1 --> fits stock S4 harness 0 280 158 117 - 550cc --> EV6 --> requires EV6 -> EV1 adapter 0 280 158 235 - 750cc --> EV14 ?

They are EV14 yes. When I initially found out about these injectors( and posted about them a few times) here(and internationally) the prices were like 20 usd/ per, now its like 40 usd/euro/pounds per since they have skyrocketed for some reason! These are used on the B8/B9 platform with the tfsi engines with additional MPI injection, if you can find a crashed one you could get em for a steal. These would still be my upgrade injetors for the future, but yes some specs would be nice, however I think there is a vid of spray pattern for it from Finjector - yes https://www.youtube.com/watch?v=9dFod4yIumsGood atomization for sure.

I am still getting hard time understanding connector type... if we take this picture: and now picture of 0280158235: it looks like it uses rounded aka denso injector type plug. Which plug / adapter you guys use? is this correct one?
