I think 2 widebands is mildly preferable to just one. As you'll have batch-fire fueling (2 batches of 4 injectors) you can request that batch 1 is injectors 1-4, and batch 2 is injectors 5-8 when you order.I plan on buying the PNP, IAT sensor, and a WideBand O2 kit with gauge. My questions lie with the WideBand.
Is it preferred to use two wide bands, one for each side?
Also, of the WideBand kits offered on the web sight are they all ready to hook up or do they need to be voltage matched to work with the PNP?
I'd really prefer to not have any hassles if possible...thanks!
You'll also need to request a 2nd wideband input when you order. Then you just turn on dual fuel tables, and table 1 controls bank 1 with feedback from wideband 1, and table 2 controls bank 2 with feedback from wideband 2. That is how I run my install and there was more of a fueling difference needed between each side of the engine to maintain an even AFR than I would have guessed. However most people don't do this and their cars run just fine.
Any of the aftermarket wideband kits are ready to work with MS, they all have at least 1 analogue output available. You may or may not have an issue with volts. Most of the time that problem is caused by an un-equal grounding of the wideband compared to MS. Meaning one has a better ground than the other. I have tried re-grounding both my MS and my widebands but I still have that difference, so I compensated with the configuration. It's not difficult.
