A hardware solution where you mod the ecu to send the same analog signal to both wb a/d inputs would do the trick as well. Although the sw mod is nicer but the result would be the same.
NO, that will be not be a reliable solution.

NO, it will not!

IF, changing the ref to stored AD-values so that the code ref the true value of just ONE sensor as suggested earlier in this thread really is a solution to the problem, then hardwire the AD-input of WB sensor2 to AD-input of WB sensor1 would effectively acomplish the same thing.

I'm not saying that you should just connect the ECU input pins together for both WBs, what i mean is that the input on the CPUs AD-channels should be modified as described. (Soldering is indeed needed)

Or have i missed something here?

There is only one ADC, they will not be sampled at the same time.

It won't, the fuel trims will still go -25% +25%. I don't think you understand why this happens, so your solution doesn't work either.

Of course, you are correct prj.  Smiley
I was blinded by the c16cx hw architecture facts and those are not really worth being mentioned compared to how the actual function works, hardware would have had minor effect compared to the code.

Yes thats right it doesnt work to feed the wb Sensor 1 signal to the AD from Sensor 2. That mod can be easily done with some jump wires and some cuts on the two wb02 IC's but it doesnt work it went straight to -25% +25%. I even tried to set any parameter wich was bank selective to equal but it doesnt help.
The only hw mod wich would work would be to use the final injection signal from injector 1+2+3 and feed this delayed to 4+5+6 but this will be a quite big circuit to add to the ecu and i don't trust it. A SW solution wich feed the injection time to 4+5+6 would be more effective. Or maybe it would be possible to buffer the wbo2 result and double it to supply the ADC with the same value.

The SW solution is to force bank 2 trims to be equal with bank 1 trims.

Basically copy over these variables:
fr_w
frm_w
fra_w
frau_w
frao_w
rkaz_w
rkat_w

Think that was it from memory.

Yes , on older cr167 even only cloning final Ti bank1 to Ti bank2 worked well. But on st10 without correct memory map and correct dpp's i will never find anything Cheesy Wich is why i'm stuck.

Just be like me and build a new manifold with seperate lambdas, one days worth of work beats a couple of months worth of work lol lol

What do you do about the post cat/turbo sensors?

Depending on your local emission test requirements (if you have any) you won't be able to pass that way.

Obd and emission tests passed with 2nd lambdas unblugged.
