What have you done to your Tacoma today? 1st Gen Edition

You have an SG or UG right? I wish I had gotten a better feel for how much timing the ECU was pulling under high load, low RPM situations when it was N/A. It would give me a better feel for when it's prone to pinging with the SC now.

 

Yeah I have an Ultragauge, I'll look at the timing advance/retard info for stock. I'll also have a look at my fuel trims and such stock as well. Although those are usually no more than 3% at any given throttle load.

 

Just Swannanoa is going on?

Passed by that town on my way to go skiing

 

Any idea if the SG can read fuel trim data? I've been interested in that side of things but never really looked into it. I just assume when my AFR hits 11.5 at WOT it's just dumping fuel lol

 

100% guarantee it can, it's a basic OBD data PID, probably just buried in the menu of options

 

have fun. Hope its a good improvement!

 

it should for sure.

11.5 WOT is great though. About perfect really for boost.

 

Me too! Honestly just the whine will at least put a smile on my face I'm sure but I'm really curious to see what it does to my ability to climb hills on the highway.

 

x2 I would consider this under the right circumstances...

I was wondering this too. The google machine indicated it is possible through xgauge codes but when I looked closer, two things became unclear. It was not easy to find any specifically identified codes for our application and also the firmware level required of the SG. Mine is a v2, and one forum suggested v4 was required.

 

No codes will be required. Fuel trims are basic OBD data that is nonspecific to the application, any $5 scantool can read them and I'm sure it is a built in option in the SG. They are probably in there labeled as LTFT and STFT

 

the whine is fun for sure.

 

I've looked when this came up the other day on Dan's truck. I didn't see them listed. At least not on mine but it is a little older now.

 

I flipped through the standard gauges and didn't get anything like those, I'll check out the user guides and see if they are options.

 

What is the difference between CANSF and CANLF

I see this: https://www.scangauge.com/xgauge/fuel-trim-canlf/

and this: https://www.scangauge.com/xgauge/cansf-fuel-trim-long-bank-1/

 

@drr and @Digiratus

I think I stand corrected after looking at three SG manuals. They're lacking much functionality of even basic OBDII Mode-6 reading. What is this thing even useful for? It basically can reset codes and read like maybe 6 OBD PIDS. I'd get a $13 BT OBD deal from Amazon and use torque which has 100% more functionality than the SG. The UG also has full OBDII PID compatibility but it costs more than the little BT dongles.

 

no you wouldnt haha

 

Ah but for us autos, it can read the all-important trans fluid temperature. Which the UG can't.

There are also X-gauge codes you can install, like the one @Digiratus linked above. I think there are over 100 possible codes you can read.

 

According to the SG website, up through 2002 we should be on the ISO standard, so I don't think those CAN codes will work. Hard to know for sure though.
Here are all the ISO codes for fuel trims, although which one is the right one?

 

I guess if the xgauge code can get you to the right memory reference in the ECU then that'd be the way to go. So weird that the predefined PIDs from the official OBD spec aren't already provided in the device. But reading auto trans temp is important.

 

You need Long Term Fuel Trim for banks one and two and Short Term for banks one and two
