4 Bar Boost Sensor not correct

Tiavoq · Post 08 Apr 2020, 13:29

I have a 4 bar boost sensor (BOSCH no: 0281 006 059 / VAG: 03K 906 051) and have also changed it to 4 bar. The only problem is he shows the boost pressure incorrectly -0.2 / -0.3 bar less than it normally is.
I hope you can correct this.

Data from the 4 bar sensor:
4.493 V = 4 bar
0.498 V = 0.5 bar

Yours sincerely

I know about this problem and am trying to find a solution.

Такая же проблема. Есть решение какое-то?

So far, you don't have to wait until autopilot finds a solution

Just wait, it will be solved soon i think.

Use boost by CAN

Thanks autopilot

а как использовать без аналогового входа давление наддува из CAN ? (А4B6)

Для этого моторные мозги должны уметь отправлять наддув на КАН шину.

Use latest update before write.

use
and not working fine

What do you mean when you say "not working fine" ?
Slowly, quickly, lower value, bigger value ?
How you check it ? Photo, video...

lower
ecu log and greddy boost gauge same boost level
color mfa lower all rpm approx 100-150kpa

I have the same issue with a Bosch 3 bar sensor

Reading are very low compared to boost controller.

I have update to the latest version also.

useless to write any problem or new options all same answer
not possible or not not plan and really not fix problem

support not very good
he only does what he likes

i asked make custom boost gauge option and possible see real pressure and vacum and use this input like additional gauge
and relocated second map intake manifold
but not .. because originally ecu not see vacum ...

ECU does not see vacuum, but mechanical gauge does ! i have one mounted and almost never use ColorMFA boost gauge even if it works correct in my car. Mechanical gauge shows at least 95 % of time pressure in vacuum area, boost is in normal drive prety rare and so ColorMFA most of the time shows zero.
