Hey There
New to EFIlive tuning. My current setup includes a ZT-2 wide band that only has an analog non linear wide band output. My ZT-2 predates the linear ZT-2(rev11).
Can this signal be mapped in either scan V7.5 or V8?
And How?
Thanks so much

Let me try something else. Here is the chart can some one help with how to transpose this table in to a PID?
Voltage 0.15 0.31 0.46 0.62 0.78 0.93 1.09 1.24 1.4 1.56 1.71 1.87 2.02 2.18
AFR 9.7 9.9 10.1 10.3 10.5 10.7 11.0 11.4 11.7 12.1 12.4 12.8 13.2 13.7
Voltage 2.34 2.5 2.65 2.80 2.96 3 3.12 3.27
AFR 14.2 14.7 15.6 16.9 18.5 18.8 19.9 21.2
Thanks dave
I'll see if an existing calc pid maps this already, otherwise I'll make you a new one.
Look forward to seeing itQuote:

This is your calc_pids.txt edited a little, see attached...
( lambda is already defined, so I used this and deleted LAMBDA; wideband lambda calculation should be done earlier than the BEN pid, so it should have a lower CLC number)
I kept the lambda expression "{EXT.AD1}*0.136+0.68" even tho it does not match the volt:afr data you posted above.
The ZT-2 pdf says AFR= 2*V + 9.6 which with stoich 14.7 AFR (from their pdf) gives lambda = 0.136*V + 0.653 which is close to what you had.
Hi Joe,
Can I point out that trona specified "non linear wide band output" in the original post.
I was wondering that myself and in that case would you need to map all the voltages instead of a formula?Quote:

Thanks for the file.
I am new to obd11 scanning and I am still struggling how to identify the WB in the list of PID's
I keep you posted when I figure it out
dave
Just Following up on ZT-2 PID
I was successful with enabling the WB using a serial WB connection to the V2. The hardware in my case was ZT2 WB controller, Opto Insulator - (protect the V2), gender changer, null modem, and V2 serial cable.
Thanks Joecar for the modified calc-pids file now were on to VE tuning
Oh, I failed to notice that, thanks.Quote:
