Good call on the V2! You will never regret it. Welcome to the party!

Cool :cheers:

Its here...been waiting years:beer:

Im a bit confused about the PID WB settings from post 476 & 477. Is this assuming I have E0 gas as it divides the equation by 14.7? Without buying a E% test kit, can I use the WB to figure out what % Ethanol my gas has? If the WB is set at 14.3 (it is) and its reading 1.02 lambda, can I assume its really E0 or richer than 14.3AFR?

Wideband will not tell you alcohol content.

Which wideband do you have...?
If it outputs serial data, then you can connect it to your V2 using a null modem serial cable
(i.e. you don't need what posts # 476,477 say... )
(i.e. you just keep the standard calc_pids.txt from the Calc.VET thread)

I see you have an LM-1... this will connect serially to V2.

Which is the best recommended WB for EFILive? Is $200 AEM any good?

Thanks joe. I had a hunch the serial pass through worked with the original calc pid. i've read up and will look for the cable supplies tomorrow.

easiest thing to do is give up on afr and go to lambda. just set your tune fueling the same as your wideband. so u dont get any wierd correction happening.
