Narrow band simulation

[cobaltssoverbooster]

I have used AEM Eugo units but i try to stick to Innovate products as i get better results.
Supposedly the LM-2 is capable of producing a simulated narrow band signal based off of the wideband. Has anyone wired this into a factory ecu to allow the ecu to use it for higher accuracy?

i am debating on weather i want to just get another MTX-L or get creative and switch over to the LM-2

This capability exists on some widebands, but it may make
a "laggy" output due to filtering behaviors which can be a
destablilizing influence. I doubt you will get any better
steady state accuracy out of it either, the element is the
same more or less with just better (closed loop) temperature
control and cal-mapping to get you the wider measurement
band. Where it counts for switch-mode closed loop, there
isn't that much variation about stoich on the OE sensors.

Welding in another bung is something I've gotten done for
a $10 bill to the exhaust shop guy doing the welding (the
front office, you don't want to talk to). Toyota oil pan plug
adds another $1.59.

i can weld it in at home no problem since i build chassis in there.
thanks for the input of the effectiveness.
if the lm-2 would produce a more accurate reading to report back on the narrowband switch point because it is technically using a better sensor i would do it but doesn't look like that is the case.
i think ill stick to the standard gauge and just use the usual afr ve error to tune it up. mtx-l it is.

thank you

Add another bung, let narrowbands be narrowbands and widebands be widebands. Don't try to make one behave like the other. I know it's a "feature" on most WB's today, but I've never had good luck with it. Not worth the potential PITA IMO

Narrowbands are faster for sure. They work well for their application.

Agreed on adding a bung for the WB. I have used the narrowband output for factory computers before, but only under extenuating circumstances

i usually keep them separated like you guys mention so this was just some random bright idea i thought i had that turned out to be what i was thinking it would be deep down; garbage idea.
