I have never got my narrowband to work with the haltech e6k.

Anybody know what the resistance readings are from the input wire to the haltech without the o2 sensor installed.

Haltech off I get 170ohms or something. Some reistance.
Haltech on I get infinite resistance. (Open circuit)?

With the 02 connected it always indicates 4mv!!

Haltech just wants me to ship it to them. I would like to get the narrow band working. It may help me with emissions

IF the input is bad you do need to send it in for checking, worst case scenario you have a wrong connection of the sensor wires and its reading wrong. Anyway, send it to California, im sure they will be able to check the ECU right way and give you an answer on whats wrong with it.

Thanks for your reply.

I went out and bought 3 narrowband single wire stock mazda sensors. For some reason back in the day I thought I was just killing them due to excessive rich conditions. Needless to say all of them are still fine. Its sort of hard to connect them wrong. There is only one wire and its the only wire on the haltech system that is big grey and sheilded LOL

It never worked and I bought it used from a authorized haltech dealer. (It was on their shop car and they upgraded to e11)

I guess winter time its getting shipped then.

Thanks,
ian

Ah, yes, only 1 wire goes to the O2 sensor input wire, no way to screw it up. This kinda confirms the fact that the input could be wrong. Have you tried wiring it through the SpareA/D input to see if measures? one thing about the single wire sensors is that they only work when warm, his is how they read right.

For a few months I tried running a single wire o2. It would work when cruising down the road but when I came to a stop for a while it would get all wacky. I had the o2 bung near the end of my DP, would cool down too much. I then switched to a heated sensor and the sucker worked great. To make things even better I moved the sensor ~6" after the turbo and now I have the wideband in the old o2 bung at the end of the DP. Having closed loop is a must these days when gas is over $3/gal.

Yes, thats what i was saying, the single wire sensors only work when they are above 800 degrees F, 3 and 4 wire narrow band sensors work way better.

And of course, widebands are the best, and with availability of low costs systems and replacement sensors the market is wide open.

I have a wideband hooked up and currently placing the narrowband signal from the innovative system to my autometer a/f meter. The wideband goes directly into my haltech. ANd the stock 2o sensor goes to the haltech input.

I know the stock narrowband works since hooking up the digital multimeter I can get readings from the 02 sensor.

I tried to hook up a three wire sensor. Same deal.

I guess I answer my own question. The haltech is pouched unless I have some weird wire issues.

Reason me asking what the ohm readings are to the haltech since I thought it was odd see resistance with the haltech off.

Thanks guys
