techedge 3E2 wideband controler autocalibration issue (EE display error)
MessagePosté :16 sept. 2018 10:14
Hello all, currently I got a techedge 3E2 to use on old aircooled vw's as a tuning toll, I saw you have a dedicated techedge section here to your forum and I decided to write down my problem, maybe someone can help. the unit seems to recalibrate on itself when on road test, without any particular reason, meaning it is not happening when you first power the unit or at another specific time but it happens. I have to say here that I haven't found yet someone else having this issue, I have communicated with Peter which gladly send me another unit to replace the first one, still the same , here I have to note that the same unit I send it back to his dealer and there it works perfectly, no issues at all
will try to note down what i have, what I have done already and what looks weird anyway
its a 3E2 with 4,9 LSU -new- long 4m cable, sensor installed with a pipe sniffer to the end of the exhaust
Powered directly on the battery with fixing screws, no help
Peter suggested to use a remote battery to power the unit, I did it but ommited to ground it on the chassis, it didn't work maybe it would work grounded? it was late when we told this as the unit was on its way back to the dealer
now what is weird -well to me at least
-both units, the first, the supposed to be damaged and the second the good one, performed in exactly the same manner, the first 2-3 days were going perfect, with no issues, and even on the "worst" circumstances meaning powered via crocodile clips etc, remember on the first unit wasn't aware that I will have problems, so i was really "untidy" on any install, then after the first days chaos, no matter what you do to correct the issue, this second same unit works directly from a cigarette lighter to the dealers car
-peter suggested that the whole thing is happening because of electromagnetic interference as the cars are old fashion, BUT the same happened to my nissan almera 2004 model where I installed it, basically the video that you will see below its on the almera car, so how did i duplicated the same environment on a new car?
I can say I;m stack, dont know how I can solve this issue, taking into consideration that me and the delaer used the same unit and sensor cable, the difference is power cable and position of sensor, he installs it directly on the header
check below a video, when the EE appears on the display, funny thing is the LEDs doesnt show calibration at that time but normal operation

I really would like to hear some inputs before I scarp the whole thing..
