{edit} to summarise that lengthy post:
“If the ecu pins for the WBO are used by the adaptor is it wired wrong?”
Hello! First post here , I’ve just bought the Ecumaster Black and the pnp adaptor for my 1JZ engine , along with a Bosch LSU 4.9 o2 sensor
I’ve been reading the “First start checklist” pdf which is very helpful. Theres a few things I’m confused about but I just want to mention one , which looks like a biggie to me - unless I’ve totally got the wrong end of the stick here .
Having bought the adaptor pretty much the only wiring to be done is wiring in the LSU4.9 o2 sensor , so I’ve been poring over various docs , watching videos , triple checking what color the wires are , what they do and - importantly - where they go .
My conclusion from this research is that “The PNP adaptor is wired up wrong”.
Is that possible? Who wires them up? - because a lot of the adverts seem to show the two connectors and a load of jumper wires rather than the fully built item. ( see p.s. comment at the end)
My reasoning for this conclusion :
I watched ECUmasters own video on wiring the sensor:
In the video we see that :
Pin 1(red wire) which is “WBO Pump current APE / IP” goes to pin B19 on the ECU , the laminated card that comes with it also says the same.
BUT looking at my pnp adaptor pin B19 has already been used!
This is a pic of the pin in use:
You can see on the middle row the run of 6 wires going from 16 to 21 , so B19 is used
Also in the pic B6 is used , which is supposed to be The black wire - “Vs”
The
“ECU1JZB_JZA70 1JZ-GTE Adapter Pinout Rev 1_1.pdf” shows this pin unused
and the startup checklist says don’t splice into used wires ( not surprisingly )
So my question is - Am I going crazy ?
p.s. further worry on the same topic: When it arrived the box said “Ecumaster classic” , I questioned the retailer and he said “yes only had classic in , so we repinned it for Black” . I didn’t know at the time that the Black connector is totally different between the models , so I just asked “let me know which pins”
He then replied a little later that “ECU master did it”
Now I know the sockets are different I realise that to do this youd have to have the one half of the correct pnp adaptor available AND it would be a full re pin !
