You know, I have reached the point where I just dont care anymore. I have spent so much time and money trying to resolve this issue and its time I switch to a different platform. I realize that not every issue is an ecu/kpro problem but the way you all conduct yourselves here is just crazy ...

Im sorry but that just doesnt make sense. I have run every test from the battery all the way down to the ecu including the pins inside the ecu soldered to the main board and voltage is a stable 14+ volts everywhere. The only place I see the wrong voltage is in kmanager. I have even purchased a $300 ...

Is that the male ecu pins that are soldered into the motherboard? Because I have already tested those and they both show 14+ volts. Is there somewhere on the actual motherboard or kpro daughter board I can test voltages?

I just got done doing more testing as well. I wired both the switched and ...

Can you tell me where on the OEM motherboard I can probe to check voltage? I've tested the hardlines that go into the motherboard on the inside of the ecu and they also show 14v+ so I know its not an ecu plug issue either.

I don't know anyone around me to plug mine into. I'm at the point where I would ship mine to you and when you plug it in to a known working vehicle and mine still doesn't work we can finally move forward. Its been years and I'm not keen on just buying another $1500 ecu to test with.

Thats a pretty broad question. Anything specific you are thinking?

Its a stock k24 turbo. The main relay is powered with a dedicated line right off the battery with an inline fuse. Its a hybrid racing universal harness. I use an aem 30-4110 O2 and I removed the relay for the OEM O2 in the ...

Lets say my multimeter is actually not reading fast enough. When I measure the ecu pins with the car off I get 12.5 volts while the kpro shows a stable 11.70 volts. What sense does that make?

What mulitmeter would I need to satisfy this? I have been dealing with this for years, since day 1 of getting my ecu back and been through several alternators and batteries with absolutely 0 change. I have tested every single piece of wire in my vehicle and they always come back as 14+ volts and ...

Is there other places I should be testing voltages that align with how the kpro reads them?

When I measure the ecu pins with my multimeter from the battery I get 14.03/14.02 so it is able to show minor changes quickly. The issue is my multimeter never drops below 14 volts while testing any wire including the ecu plugs but the kpro shows readings from as low as 11.60 to only ever as high as ...

If I am testing from the battery to the ecu plugs and it shows the same voltage the alt is putting out does that not mean the ecu is getting full voltage? Also, none of the voltages I have tested are unstable. Why would the kpro show such an unstable voltage reading?

I am testing from the battery to the ECU plugs. There is no drop.

I tested several more times and here are the results

From batt neg to A2 and A3 I get 14
From batt pos to A2 and A3 I get .03

From batt neg to A4 and A5 I get .07
From batt pos to A4 and A5 I get 14

It seems as if the issue is within the ECU or kpro itself. Is there a way I can test inside the ...

I want to reference from this post:

You told him to check the voltages from the battery posts to A2 and A4 so thats what I did.

From Battery Pos to A2 = .22
From Battery Neg to A4 = .03

From Battery Pos to A4 ...

I ran a dedicated wire from the battery to the conversion harness to power the ecu rather than through the oem fuse box and the voltage is much more stable in kmanager but it still never seems to go above 13.5 despite the wire itself providing full voltage and the ecu plugs reading full voltage as ...
