E36 M3

[Frank70]

Hi,

 

I have an E36 M3, it has two lambda sensors as standard, what do you guys do in this instance? Is it okay to just use one?

I see a lot of people don't even use them on NA vehicles, but I don't know how the emissions test would work out for road use.

 

Any advice will be appreciated, thanks!

What ECU do you have?

I was looking to go with a Storm if I decide not to use a lambda or maybe an higher model if it is necessary to do so. It is a good NA engine and I have no plans at all of introducing boost at any point.

 

I am set on using Link due to previous use and support.

You can do 2 bank closed loop lambda control or 2 bank narrow band control on a 6 cyl if you wish (ie correct 3 front cylinders and 3 rear cylinders separately).  Most people would just use a single wideband after the collector.

Good stuff, I used a Thunder previously on the first Honda but I'll be honest in that I cannot really stretch to it for this project, the BMW is much milder and trying to stay simple.

That is excellent information as always, the final sentence hits the nail on the head I think. Thank you!
