Default Wideband O2 sensors with straight methanol.

I've got a low power naturally aspriated deal I'm running on alcohol for consistency.

I'll be running an EFI system, but need to datalog AFR. Holley suggests using an NTK sensor for ethanol and methanol, which they have available as part# 554-100 for like $250 more than what their system comes with. On the flip side, when you glance over at FAST, their "Ethanol/Methanol" meter controller has a Bosch sensor. So I called and asked, and they said "it crosses over to a Bosch part# 17205. So I'm like wtf lol.

Holley's Terminator X comes with a Bosch sensor, and AEM X-series AFR controllers come with a Bosch sensor, but..... what's the problem with using a Bosch sensor?

So some have trouble reading methanol at air/fuel readings that low (rich). Makes sense.

I see you're successfully using a 17018, which i think swaps in place of a 17205. Is there anything more on this? Like is a 17205 just a better sensor, of the two?
