I'm back. Last week, Thursday, me and my wife went to PC Beach to watch it rain.
Paul, so the eBayer lied to me? I know this is cheap. Below is a picture of it after I bought it. I do have a 5 wire Bosch wideband sensor only.
I'll look at those better gauges and get one. Which bin file have you been disassembling?

read the pre tune info

Unless you spend over $1,000 your not going to get anything near the quality of the AEM wideband

plx, innovate, afr, etc... are all sub par compared to the AEM

Yeah, that is definitely not a wideband setup at all. I have used AEM in the past any they are very good and easy to configure. You may want to buy a complete setup, all sensors are not the same, even if the connector is. Only use the sensor that the gauge manufacturer recommends, that is what the gauge and controller are calibrated for.

Is this legit? https://www.ebay.com/itm/356038173757?c ... gLAnfD_BwE MP "I highly recommend the AEM 30-4110 widebands. Be sure to set the wideband to report LAMBDA on the gauge by setting the adjustment screw on the backside to mode P1. The best pricing on the AEM widebands I have found thus far is from MAPerformance which is less than $160 shipped. If you find better pricing, please do let me know."
If this is legit, consider it me letting you know.
ADDED LATER: I just now saw $69.95 shipping so that is getting close to MAPerformance price...

Thanks for adding the link. I had looked at it then didn't think to add it here where others could access it from here. I have an AEM kit on the way and will install it in the lh exhaust pipe. The O2 sensor bung already had the cheap kit installed in it. I'll remove it and AEM wideband AFR kit.
I turned the engine over a few times with the PCM relay pulled out to see if I'm getting any oil pressure. I'm tempted to remove the camshaft position sensor and turn the pump with a speed wrench to get some oil pressure. I know that the oversized oil filter is empty so it would take quite a few oil pump revolutions to build some pressure.

Just take the cheap sensor out and put the aem one in. The cheap sensor is a narrow band sensor and reads just like a stock one and is of no use. The egr location looks to be angled too much and won’t put the sensor in the middle of the exhaust flow. Looks like it will be against the side of the manifold.
Also, you will need to use a strong drill to get oil pressure with the oil pump drive shaft. A speed wrench by hand will not do it. And once it starts to build a little pressure a regular drill won’t be able to turn it over. Need to use a good heavy duty 1/2” drill.

After reading https://www.autosuccessonline.com/wideb ... fferences/, I see that the dead give away is the cheap kit that I bought is a narrowband o2 sensor kit and the sensor only has 4 wires. I have a BOSCH 5 wire sensor only, so yes, I can see the 5 wires coming out of it.

Yes, but I would buy a complete kit that comes with a sensor. There are a few different sensors that are wideband sensors, and they all read differently. Make sure you buy a kit and use the sensor that comes with the kit. That is very important. Unless you have a part number on the sensor, and it corresponds with the manufacturer's specifications for the gauge and controller. But I recommend you buy the kit and use the included sensor.

Paul, The AEM AFR o2 sensor gauge and kit is on the shopping list. Thanks for the ID on the cheap kit that I was misled purchasing just because someone stated that it was a wideband kit. I'm learning a lot here in a short amount of time.
I'm ready to start this truck for the first time, even without the new AFR kit installed. I just want to hear it run for 10 seconds. Yesterday, I used an '86 "fox body" distributor that had the drive gear removed to pump up the engine. The 3/8" cordless drill fit the 1/4" top shaft. The housing made the whole process very stable. On my antique analog oil gauge, it was reading 44 #s of oil pressure at 75 degrees F. cold 5W30 oil. The engine would not fire because fuse 19 was missing, a 25-amp micro mini fuse for the ignition and PCM.
