It looks like I found a xGauge that works for this; although I dont know which o2 sensor the scangauge is reading from. I'm using the CANSF Alt A/F Bank1 Sensor1 data:

CANSF Alt A/F Bank1 Sensor1 data - TXD: 07DF0134 RXF: 04414534 RXD: 2808 MTH: 05B900800000

Also the 'general' AF data works as well:

CANSF Alt A/F General - TXD: 07DF0144 RXF: 04414544 RXD: 2808 MTH: 05B900800000

Effective (visible) A/F range on the gauge is 14.6:1 at idle, 20:1 when decelerating, and 12:1 when full throtle. Although the reaction time is slow as mole-asses the data is pretty good for the cost.


One thing I definatly noticed is the car has got to be HOT for the scangauge to read anything other than 14.6:1. I had to drive around the block before it started working right. I believe this has to do with the o2 sensor's operating heat range.

Best regards!

 

Dont ask me to program xGauges cause I dont know how. I found this A/F xGauge here:

I love you.


I know the R56 uses an on board wideband, and I knew in theory that the ScanGauge should be able to read it.

I have never found any code that worked though, so I will definitely be trying yours out!

 

Let me know how it works out for your '08 MCS. These codes work on my '09 Factory JCW.

 

Unclemeat,

Thanks for posting the xgauge codes. I think I might try them for HP and oil temp.

 

I already tried oil temp but could not get it to work. HP works but its what I call an 'idiot' gauge.

 

Yup got the AFR to work! Kinda cool...definitely not as fast as a true wideband afr gauge, but it gives you a rough idea.

I used the 'general' one. Anybody know what all the other ones are? Like afr bank 1, sensor 1....bank 1 sensor 2....etc?

I would love to get one that works for oil temp. I love my Scan Gauge....

 

What is the highest you have seen your hp at?

 

The HP reading on a SCII is an estimated/calculated number and while fun to watch it's not a number to base much on.

 

I know, but he has a JCW I think, and I got my scangauge to 230 with my car. I was just wondering what he saw?? It has no basis in reality, I was just curious.

 

None of the other banks worked for me, and I think alt-general is really the same as alt-bank1.

I see 245 hp via the scangauge. Really inaccurate since I a lot less but still good on the dyno: 215fwhp 230tq

 

You're tuned right? What mods...

 

No tune, no mods. 215fwhp 230tq on a stock 2009 JCW. I've been somewhat quite about it all especially in the Cooper S forum since I dont want to get bashed. I believe the numbers are very legitimate performed by a well known shop here in Atlanta. Same day - Honda S2000s could not get over 200 rwhp. Thread located here:

https://www.northamericanmotoring.co...-jcw-dyno.html

Since the dyno pulls I've added a Forge Front Mount, Forge turbo to IC charge pipe, Intake Muffler delete, and Craven stock airfilter replacement (Hiflow?). Will dyno again very very soon, followed thereafter with custom tuning done by WayMotorWorks (Dimsport). Maybe I'll see 240 whp?? Who knows.

 

Nice numbers man!

 

So I started playing around with the xgauge stuff too. Very cool! can't believe I didn't play with this stuff sooner.

I can confirm most of the what the initial post said (14.6 ... high AF on deccel, etc). I only took it around the block. I'm most curious about 4th gear, WOT on the highway. So I'll try that later this evening or the weekend.

Doesn't appear the HPR one is very useful. <snicker>

Also noted that intake air tempt was just 5 degrees above ambient with the IC. That's never getting higher than 3rd gear just putting around my nieghborhood (69 degrees outside.. 74-75 intake temps).

 

* Bank1 refers to left side of engine (includes cylinder #1)
* Bank2 refers to right side of engine (does not apply to the R56 engine)
* Sensor numbers increase as they travel from the engine block to the exhaust tip, so B1S1 is pre-cat sensor on left side of engine. B1S2 is post-cat sensor on left side of engine. B2S2 would be post-cat sensor on split exhaust, for say a V6 or V8 engine.

FYI, the oxygen sensor closest to the engine will be the primary contributor for AFR readings. The main purpose of the post-cat oxygen sensor is to determine if the cat is functioning properly (P0420 anyone?).

Hope it helps,
Jeff

 

Ok so is general just a weighted average across the sensors?

 

That's a question for the ScanGauge tech support. I can tell you that the 'general' selection is not part of the OBD-II spec (the foundation of all emissions diagnostics through the OBD-II diagnostic port). I would assume (you know what they say about assumptions) that instead of an average, general is the B1S1 reading, but I could be wrong.

Cheers,
Jeff

 

Thanks for the help man!

 

Wow, Mine was at 12.4 in third 6500 rpm all out. Thats cool that the ecu compensates for the water meth.

 

So who is working on the oil temp???
