Uploaded 1.2.31

Made a new wiring harness.

Now i have no lambda data while driving.

EGO call.http://www.vems.hu/files/MembersPage/PeterJensen/S2/v3.3_u010045-2018.06.25-21.45.36_31.vemslog

Shuld i try a LSU 4.2


Hello Peter,

I have reviewed your log v3.3_u010045-2018.06.25-21.45.36_31.vemslog, you are not getting lambda reading beacause there is still a problem with the heater and pump control as i explained before (but it seems to have gotten worse now, Ri is not measuring at all). If the loom is new than wiring is also unlikely to be the culprid therefore i cannot reach any other conclusion than some hardware failure in the wb circuit.

Please fire a repair request in webshop to get the ecu diagnosed.

Best regards,

Dave

Lambda EGO flag is flashing

Sensor is new 4.9

Sensor cal. log

Hello Peter,

I have reviewed your wbo2 warmup log, there is indeed a problem there. Both the Ri and Nerst Dc measurement are oscillating around target not stable like needed and control actuation seems to act in bang-bang fashion.

To rule out any firmware problem (you are running 1.2.33 which is marked internal, not even testing; see GenBoard/UnderDevelopment/FirmwareChanges) i would recommend you upgrade firmware to the latest released which is 1.2.38.

Could you take another log of wbo2 calibration using this firmware ? Thanks! I'll review and provide hints on next steps after.

Best regards,

Dave

Lambda EGO flag is flashing

Seen that EGO correction is not constand.

Cant see why

LSU 4.9

ECU Audi 3b PnP

Log can be find her

Hello Peter,

To get an idea whats going on, could you make a vemslog of wbo2 calibration running (no need to take sensor out of the exhaust, just make sure the sensor is cold when starting the calibration) after starting let the log run for at least 5 minutes.

Please link the log here so i can review, we'll work from there; Thanks!

Best regards, Dave

We did flash the ecu but no serial communication.

Did load boot.hex and set all fuses.

before flash VT could see the ecu?

Maybe there is something wrong with a part of the AT128.

Is there anything else we can tray?

Thank you for fast support

New Serial connection problem Need help

Box nr. v3/17302 DBW

Car Supersaloon LS2 1000 Nm

End user saved config from old (2017) ecu and uploaded to new ecu.

I think they used latest stable from 2016 and did not do a ini update. After reboot he could not get serial connection. I have tested but no luck.
  • measure voltage on DSUB9/pin2 (from ECU) and DSUB9/pin3 (from PC), just in case.

VT says ecu found and when it start to load pages it stops at page 1. Then ecu disconnected - no ecu found.

Replaced max 232 but no luck.

Car and team must be racing at 22-06-2018.

How can we help them ASAP- new ecu-isp firmware flash or any other help will be great.

Do you have ISP hardware ? (eg. "bsd" cable or "usbtiny" cable ?)

I have isp from web shop but newer tested it

Thank you

Problem solved

Serial connection

I replaced max232 and it is now working aging.

Thank you for great support

Need Help: ECU runs but no serial connection (MAX232 problem suspected if wiring has good ground and no intermittent RX/TX problem).

End user had problems connecting to ecu.

We have tested on 5 pc and many usb to serial connectors.

Problem started as a small issue but got worse over the time and now we have total lost any kind of connection.

ECU 17956

The ecu is running nice in the testbench but no communications.

You can measure and check outside connection and disassemble if that does not solve. Do you have a spare ST232D or MAX232 (SOIC16) IC already ?

I really need to get his car up and running so please help.

Round only AIM

Hi

Setting up aim coolant temperature something goes wrong while temp goes form 99 to 100 degrees. Should be 100 but at the display i can see number 180. I have used the predefined values and working great until it gets to 100 degrees.

Firmware version 0.5.3
