Sidewaysste

I know it's been covered before, but I want to make absolutely sure I get it right and the guides aren't clear to me.

Would someone be good enough to give a step by step guide how to wire in and set up an innovate LM-1 WB02 with a NON pro HP Tuners MPVI2 please?

I'm hoping there's a way the WB can be used in place of one of the stock narrowband sensors so that I don't have to weld in another bung.

It's an LQ9 and P59 PCM by the way,

Thanks guys!

If your WB has a serial out, you can get a serial to USB adapter to connect to your laptop. I do that even though I have a Pro.

I wired one through the ac pressure switch and found a youtube video that describes exactly how to set it up. Worked perfect.

I have mine wired up through the AC Pressure interface. There are three wires on the AC pressure sensor - ground, 5 volt reference and signal. You attach the output from the wideband to the signal wire. You can find the signal wire with a multimeter. The ground wire will have continuity to the engine block with the key off. The 5 volt reference has 5 volts with the key on. The signal wire has neither thing.

Once you have it wired, you have to add a channel for the AC pressure sensor voltage in HP Tuners. Once you connect the wiring, make sure that the AC pressure sensor (wideband) reads 4.5 volts with the key off. That's the full lean reading (usually). From there, you need to create a math parameter to convert the voltage signal being received into an understandable AFR for you. The literature for the wideband should have an equation that converts a given voltage into AFR. For the AEM UEGO unit I used, it was "AFR = (2.3750 * Volts) + 7.3125". When you create the math parameter, you have to switch "Volts" in the equation with the reading from the AC pressure sensor. You do that by selecting the parameter to include in place of the "Volts". It appears as numbers in brackets like this "[2210]". Once you have the custom parameter specified, you can graph it and display it in charts by clicking on the "User Defined" section.

This!!

I was going to use the AC pressure switch as well until I figured out I could just use the serial out on the WB direct to the PC and then just config the external channel with the WB you are using.

Here is my thread asking the same question you did and the help I got.

Is there a reason you do this? Does serial provide more accurate readings?

The AFR signal was super fuzzy while connected via 5V output wire. The serial out cleared it up, also it's as accurate as you can get.

Is this pic from using the 5v output wire or the serial connection? I'm guessing 5v, as that is what my wideband looks like lol

i use the serial also hooked to my usb port. easy. accurate. no wiring required. and i can use my ac while i tune. haha

Yes, the 5v output. Even with key on engine off the AFR was jumping around on the scanner. Once switched over to serial out, it's spot on.
