Yes, there are a lot of fake greens around.
The bore of the holes is not as "sharp" as real ones.
As prj said, not recognisable for me without real ones to look at the same time.

The Dekas are the ones you have to put alot of effort to to get the idle ok. The greens work fine in my opinion.

Why not use correct TVUB when known from R ECU?

KVB is 0x1CE82.

Have fun with your dream car Smiley

The injectors are original Bosch bought from a UK company and are manufactured in Brazil.I paid almost 300 pounds for them.
They have not been flow tested before install on the car .I know very well that the flow differences between the injectors can lead to unstable idling and I am going to test them.
TVUB values are from S60R ECU   ..... 1.81  , 1.20  , 0.77  , 0.50 ,  0.38
Are you sure about KVB address?I tried and the values in cm3/min  ​​appear incorrect.
2 byte size (16 Bit) and 0.1 factor  or  1 byte (8 Bit) and 3.046875 factor?
I have also attached the definition file today.
Thank You.

I am absolutely sure.
Actualy it is called "KVACAL" in this Volvo ME7.0.

It is a 16Bit LoHi. The Value is not in ccm. It is normalized to some specific flow at some specific pwm of the injector driver.
Have to look that up, dont remeber it fully. But doesnt realy matter. Scale it according to the flow rate change and it will work properly Wink

Use these Binary Hex Values for TVUB: 0x0276 0x01AB 0x0130 0x00E5 0x00B4.
These are taken from an ME7.0 from an MY2000 R, not from a ME7.01 MY2003.
These values do incorporate injector driver dead times too and they are different between ME7.0 and ME7.01 in Volvo.

Dont rely on any xdf floating around. Spend some time with IDA Wink

Best regards

I really appreciate your help and if I don't ask too much can you send me the ME7.0 R file if you have it?
I want to see the other important maps for the correct settings of the injectors.
On the other hand, the engine with green injectors and 19T turbo that was installed in 2000 R cars was B5244T2 (2434 cc ,265Hp and 350Nm torque).Only good values are for TVUB, the rest of the maps do not fit the B5234T engine (different displacement).
Thank you!

:)Hello guys. After many years in which I abandoned my soul car 1999 Volvo V70 2.3T5 ,I managed to finish the engine with some improvements for more power. Turbo 20T ,Bosch green 0280155968 injectors , intake pipe , aluminum intercooler , exhaust  ,etc.I set the injectors correctly with TVUB values from S60R file and KRKTE 0.06747 ( original 0.07992 with blue 0280155830) . The problem is idle which oscillates between 840 and 890 rpm.I think it is from the green injectors. Many tuners say that they are the worst choice and that Bosch EV14 would be much better.No problem with the blue ones.I ordered the 627 cc/min EV14 0280158123 injectors and extenders because they are the standard lenght.
Please help me find KVB because the file from 1999 is 512 kb and I'm struggling with it .I have attached the original and mod files and some logs with car idling.
Thanks to all! Marian from Romania.

 

i usually have my guys get 00 ( 1 mb ecu ) and clone the immo and it works great! and then 10ERHJ software flash and bam ez tuning / logging

those 512kb softwares i dont fuck with. dont take them from the S60R cause thats a decos system, the p80 one is a regulator.
take the dead times from the data sheet you get from ur manufacturer.
should be more in the 0.0543212093 range on krkte with those ( this is for the 627cc injectors )

( im pretty sure thats a 1:1 regulator 3 bar base yee? and not a fixed 3.8 bar like some others)
gl, report back!

Hello! I also thought of cloning the ECU with 1Mb file but I don't know which would be suitable. I found to buy an ECU from a 2001 Volvo C70 2.0T with serial 0261206272 ,08627456A .It is good? And IMMO file  from 99 512Kb ECU works in 1Mb ECU? The EEPROM is the same?How to clone it?
The 1999 P80 cars have ME7.0 with a regulator near the fuel filter under the car, but the pressure is 3.8 bars as with the S60R decos system. In T5 file KRKTE is 0.07992 with blue injectors ( 262 g/min from specification).For 0280158123 EV14 429 g/min I calculated KRKTE
0.04837 . TVUB values I will get them from Porsche 997 file which has these injectors from the factory.Fuel pressure is also 3.8 bar.

I suppose it's just done by extracting data from the SQL database?

1. here is the code to extract data from the vida db

2. RAM from A6 identifier offset table

Can someone confirm that this file is from P80 T5 cars and have 10ERHJ software?Manual or Auto gearbox?
