Got the Bosch sensor bung installed, and then ran the wire over the top of the transmission to the engine bay near the master cylinder, then into the cab through the firewall with all the other gadgets. Wired it all up, but it wouldn't work. Got on with tech support and we troubleshot it, and everything seems to be working as expected, except that no signal is coming from the Sensor Processor (built into the wire that comes from the sensor and comes in through the firewall). So bascially, I left the gauge and the O2 sensor, and sent the rest back. FAST said they would test the Processor, and fix it, or most likely just send me a new one that they have verified is working. So I am on hold with the installation until they send the fixed/new one back. Pics to follow...
The A/F kit is FAST #170634 Wide-Band Air/Fuel Gauge Kit. From Summit for around $200. It comes with the Bosch O2 sensor, a harness to the Sensor Processor, and the gauge, wiring, and connectors. For now, I have the gauge temporarily mounted on top of the steering column for easy viewing while driving and test-and-tune, but once I get the carb dialed in, I will move it down with the other 3 gauges. Maybe...
that looks really nice. I like the fact that you put it right next to the tachometer, I'm gonna try to mount it the same way and have a vacuum gauge nearby too. Did you do the welding yourself, looks clean.
yes, welded myself. Not as clean as it looks. It is a cheap harbor freight flux core welder, so it spits and spatters pretty bad. I used an angle grinder with a flapper wheel to clean it up. I still havn't decided if I will keep the A/F gauge there or move it down south. It all depends on how much I end up watching it.
Have seen it in auto parts stores for 50 bucks!!! Insain!!! So mine will have to wait... I would also like to know how effective it is.
The gauge is $50, but the kit I bought came with the Bosch O2 sensor, the weld-in bung, and a long cable that has a computer built into it (that was the faulty part I had to send back for a swap), then the gauge, plus all the splicing connections etc. You an buy just the sensor, and hook up a multimeter and read that, but you have to be able to convert the mA to A/F on the fly. And the range within which we are hoping to be with our ratios is very small.
Yeah, I tried using an O2 sensor and mulit-meter once. It worked like it was supposed to but sure was not worth a crap going down the road trying to figure it out on the fly. Didn't help that I suck at math either. I like the system you have and would like to try that one myself clint
When the processor gets back and I install it and get it working, I PROMISE to post how well it works (or doesn't).
