ScanGauge2 - A/F & TFT

[TRD 4RNR]

.
1999 | CA Emissions | 2 Cat

Used the following codes and got the results seen in the photo.
I had to try a bunch of different A/F codes before finally getting it to work with the code below.

Anyone know how I can get the "." to show as 15.1

TXD: 686AF10114
RXF: 04410514
RXD: 2808
MTH: 05B905000000
NAME: A/F (Air Fuel Ratio)

TXD: 686AF101B4
RXF: 044105B40000
RXD: 2808
MTH: 0009000 5FFD8
NAME: TFT (Trans Fluid Temp)

I believe I actually use this on my '99 CA 4Runner:

TXD: 686AF10124
RXF: 04414524
RXD: 2808
MTH: 05B900800000
NAM: A/F

I never really found the A/F ratio to be that interesting - the reading is very slow through OBD-II and you can't necessarily trust it to be perfectly accurate. Then again, my engine is currently stock other than a few intake mods.

Thanks, I'll give that one a shot (although I think I tried that one already). I have a Supercharger & 7th Injector - really want to get a better sence of where the A/F is. I took it out for a drive earlier and do see what you're referring to with the delay. That said I can see it's generally around 14.7 and dropped to 11.5 @ 5# of boost.

I somewhere have what I’m pretty sure is the AF for my 97. I’m pretty sure it’s just the math to get the decimal point.

I’ll try and find my thread on it and bump it to the top. Your 99 has the newer ECU. It may not entirely be the same. It’s worth a shot though.

If it doesn't work, I'll have to review what is actually on my Scangauge rather than just in my notes...

I found one that works for my:
1999 / CA Emissions / 2 Cat

TXD: 686AF10114
RXF: 044145140000
RXD: 2808
MTH: 05B900800000
NAM: A/F (14.7)

I believe my issue was that I was not refreshing the gauge when making an adjustment to it. I'm sure I tried this one yesterday but today I added it to a new location from scratch and it is delivering the format correctly - i.e. 14.7

Thanks for your time/help.

and thank you [MENTION=198376]4Runner4Leon[/MENTION]

Thank you - looks great!

When I get my rig back on the road I’m going to try your 14 memory address and compare it to what I feel is the AF for my 97.
