Title: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: ibizaCUPRA18t on December 29, 2018, 02:27:14 AM Hi,
Been on the look for voltage specs for these injectors and cannot find them anywhere. At one point I thought of using 750cc values @4bar but I don’t want to guess... Any of you have data for these? OEM number 0280158209 Thanks. Title: Re: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: Leonhard on December 30, 2018, 10:07:16 AM according to Bosch info these injectors are making 600g/min @ 3bar (857ccm/min)
Resistance 12 Ohm Title: Re: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: ibizaCUPRA18t on December 30, 2018, 03:18:37 PM according to Bosch info these injectors are making 600g/min @ 3bar (857ccm/min) Resistance 12 Ohm Hi, thanks for trying to help out. I need dead times for 16v, 14v, 10v, 8v, and 6v if I remember correctly. I could use voltages from a 750cc @ 4 bar but it would still not be the same.

I'm using 0280158040 (670g/min) within this range, working quite well on a 1.8T, with these deadtimes: 8 10 12 14 16V 2,5 1,5 1,1 0,8 0,6ms Title: Re: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: ibizaCUPRA18t on January 06, 2019, 12:50:08 PM I'm trying to get more info of these rarely used ones ;) I'm using 0280158040 (670g/min) within this range, working quite well on a 1.8T, with these deadtimes: 8 10 12 14 16V 2,5 1,5 1,1 0,8 0,6ms Nice! You mean 670cc versions with long nose and 7-holes? I will be trying 750cc values @ 4 bar. Then I will test your values.

I am very thankful man I was willing to pay money for this... Nice that bosch informed you. I could not contact them. You have helped me a LOT now I don't have to guess KRKTE Values and TVUB either. Hope you have a great day my friend. If you need help with anything just pm me. +1 Title: Re: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: lepatron972 on January 12, 2019, 04:55:26 AM Hi,
I am looking for voltage specifications for these injectors Bosch EV14-ES 0280158042 and can not find them anywhere, in the hitachi ecu of vehicles that use these injectors there is only one point for 14V but I do not have the offset to have value either. who can help me? Thanks you.

Did any body had any chance with the above TVUB values ? Ive tried the above values and the AFR is way off in idle . I had to correct the KRKTE from 0.0442 (according the calulations on FR ) to 0.0385 just to go close to stoichiometric (14.5 on wideband ) . Any advise ? Engine cc = 1970 Temin = 0.15 Fuel Pressure is = 3 bar Title: Re: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: lepatron972 on January 03, 2022, 04:44:34 AM Krkte =0,041257053333333 %/ms
For 3,0 bar pressure. AFR stœchiométric Is 14,7 for gasoline not 14,5 14,5 afr is for Diesel Envoyé de mon iPhone en utilisant Tapatalk Pro Title: Re: Bosch EV 870CC Part nr. 0280158209 Looking for TVUB Post by: usabug on January 03, 2022, 05:40:02 AM Krkte =0,041257053333333 %/ms Anything bigger than 0.385 i am running on 13ish AFR For 3,0 bar pressure. AFR stœchiométric Is 14,7 for gasoline not 14,5 14,5 afr is for Diesel I am aware the value of 14.7 ... i said just to go CLOSE to stoichiometric , which means that from 13.4 --> i went with krkte = 0.0385 to 14.5 AFR on wideband ... So since the temin is already very small (0.15ms cannot make such difference ) , FKKVS = all 1 , MAF = OEM , that makes me wonder if the TVUB on the post above maybe not be correct . |
