What changes with adding the second sensor? is it going to get the tune closer/better? are most people adding the second 02 sensor or just using the single?

Two here. More accurate monitoring and correcting we had some days where it was below-10 here. It started up right away and drove around great.

The second O2 connector on the harness is different, but there is an adapter connector to fit the Bosch O2 17014.

With the second O2 sensor the ECU will correct for each bank instead of correcting the whole engine by sampling one bank. Had a bad injector on the passenger side, but the ECU didn't show any problem until the second O2 was added. It is an inexpensive but worthwhile addition.

Is the adapter connector included in the kit for the second Bosch sensor?

dmracing

Yes. You just need to buy the sensor and plug it in

I think you have to set up the hand held for it too. It’s been a while and I don’t remember that

Will this connect to the stock LS3 injectors with no problem?

dmracing

iTrader: (80)

Yep. That’s what I have right now.

Cool thanx and keep up the posts on this topic. I am really thinking about going this route on my new build.

Does the manual state specifically over 10 OHM? 9 OHM won't work?

I was thinking the Bosch 210lb HI-z CNG injectors? MS3 and other similar HI-Z only drivers seem to do it with no issues.

How about electric fan control? does this have the fuse/relay already or just a ground trigger wire?

dmracing

Fuse/relay ground trigger

So the fans and the fuel pump are each just a 1 wire hookup?

Thanks for answering all my questions, I’m going to be ordering this very soon.

Yep. That’s it. Very simple. Great budget system. Especially if you don’t need the trans controller

I'd ask what drivers are used and what the max amp draw is. Assuming they use the VND5N07 drivers like most others, they could drive the 210's no problem.

That could be interesting. That would change things

Hopefully its still pretty good/simple with the trans control, because thats what I need for a 4l60.
