Hello, i am rebuilding my car right now, using my “old” Ecumaster Black (REV: F)
i used to have an LSU 4.2 with the old Engine Setup and switched to LSU 4.9 with the new build. 2nd Lambda is connected vie Lambda to Can-Bus and works fine after a little help from the community but my main Lambda directly wired to ECU doesnt work, its always shows Lambda 1.00 and software says not plausible.
I changed to another Sensor, i also checked the current sensor with the Lambda to Can Module and the Sensor is not the Problem.
i ordered new Connector and pins rewired everything checked wiring before and after, still no difference, can anybody help me what i done wrong or have to check?
I think Black can read only 4.2
No….black can also read 4.9.
Check ur wiring…4.2 is confusingly different to 4.9…if this is correct check sw setting….there u need ti set the type.
Im having the same issue with a 4.9, its stuck at lambda 1.01. I am not very electronics smart and I have spliced the wires to go both to the AEM gage and to the BLACK so that may be something i work back. But I have seen enough cases to think theres either something tricky about it or I have something backwards.
don’t do that. wideband controllers don’t share
Thank you for your patience with a newb. wired everything into the ecu and its been working for a while. Now i just need another sensor for the aem gage in the car.
Update: Didnt anything after the last rewiring, we did the start tune on the car now and as soon as EGT shows 150°C and more the LSU does work, so my guess is its something with the ECU Lambda heater…
Is there a possibility to send the ECU tu ECUMASTER to check everything?
Greetings Axel
