WB sensor & gauge compatible with stock ECU and PiMP ECU

[mustanginaz]

Hi,

I want to monitor my AFR with a O2 gauge. Can I add a WB sensor that is compatible with my stock ECU and will be compatible with a PiMPX ECU when I upgrade in the future? Do you offer a sensor & gauge kit that will do this? I just want monitor AFR on my 84 SVO which is mostly stock but I have added an adjustable fuel pressure regulator, hence I want to monitor AFR now and in the future with a PiMPX when I get one. Has a very efficient FMIC, Ranger roller rocker head, other than that, mostly stock.

Thanks-

The stock ECU's can't use a wideband o2 setup at all UNLESS you connect it to the "narrowband simulate" wire which just makes the wideband act like a narrowband.

So you either:

1) Install a wideband setup near the end of the downpipe (where it should be regardless of the ECU) and simply look at the gauge to monitor AFR with the stock ECU, then wire it to the PiMPx when you get one (just one wire goes to the ECU).

2) Do the same as above, BUT you remove the stock o2 sensor and use the narrowband simulate feature for the time being (until you get the PiMPx).

I've used method 1 in the past, there is no reason to do method 2 if you've already got a working stock o2 sensor as nothing is gained over method 1.

Any of our widebands that have a gauge (AEM Gauge, Spartan 2 w/Gauge) will allow this. AEM is currently in stock.

thanks for the info, any idea when you will have the spartan 2 in stock?

We're getting a small batch middle of next week but it's not much more than what's needed to fulfill current backorders.

to this end as long as I have a 5vlt positive signal to pin 29 of the pimpxs I should be good (88 turbo coupe, cas/cop, stock injectors, stock turbo)AEM P/N 30-300

Yes, as long as the power and ground wires are also connected correctly.

Thanks.
