Oil temp and A/F ratio

I know some of the guys on here know pretty much everything about the Busa motor (Gen II). How would I install an oil temp gauge? Is there a plug somewhere where I could easily bolt in a sensor? Guys I'm looking for an EASY install so that even a half dead monkey could do it!


Next, the same for the A/F ratio. I looked at autometer gauges and they have narrow band gauges that look like all I need for my own geeky interest. How would I install one of those? Do they use any pre-existing factory sensor so I don't have to drill and tap a new sensor into the exhaust? Again, I'm looking for something so simple to install that your 12 yr old daughter could do it in 20 minutes.......

Well, is any of this possible? Using any brand of gauge? Thanks for the info!
 
unless the pipe has a second bung installed, you are SOL on the O2 sensor.. pipe needs to come off and have a bung welded in.. EGT is a different story, hole can be punched and the mounting bung will self thread.. I would bet someone like SmithBusa could piggy back the factory O2 sensor for you with an LED readout if the price was right..

Oil temp.. ? depends on the type you have.. most use a thermocouple again and you will need to either get an "inline" banjo type fitting or remove, drill, tap oil pan?...

IMHO, unless you are doing tuning, extended HIGH rpm runs.. both are probably just bling.. Oil temp can be extrapolated from the coolant temp normally.. (oil coolers are really not even needed on the majority of these bike IMO)

Now, a 12 year old COULD drop the bike off at shop and pay the bill...

there are a few places in the oil gallery where you could add a oil temp and/or pressure sensor. Look around and you'll see the plugs. I have mine mounted in the main gallery.

Narrow band lambda's are pointless.

I agree with bogus on the oil coolers being overkill. If your gonna do an af gauge don't wate your time with narrow band. Its really a waste of money and time. You can also enjoy benefits of a wide band later if you decide to datalog or tune for power adderrs.

My oil temp is in my pan....reads 170's out of boost and 190's after boosting when its in the 60's.....when its 90-100 degree outside the temps will be 220 when crusing on the hwy
 
Why would you want to put a a/f ratio meter on anyway. If you did what are you going to do when you find out your lean. Same with oil temp, its to hot or its to cold. These are things you don't want to know. See its so easy a cave man can do it. :laugh:
 
Once the engine oil is warmed up the location of the temp sensor isn't very critical. Alot of applications are different but I would shoot for the 200's on the street and like Mr Bogus mentioned higher for racing. It also deopends on the oil you're running. You don't want the oil temp to get so high that the oil begins to break down and cook.

well what do you suggest....maybe my gauge is wrong...this is also taken in the oil pan

I run regular Castrol 20/50 and change oil and filter every 1K miles. Like I said in cooler weather it run in the 170's if its hot outside it runs 215....then if you boost some it rises probably 30 degrees
 
Well, as usual you guys answered my question! Thanks. I guess for my own geekiness, I will not install the gauges. My bike is at the dealership getting a quote to fix anything damaged when it was stolen. I will have to see how that bill comes out. Probably get it back in three weeks......
 
sent you a PM. :thumbsup: I don't want to hijack the thread any further.

PM didn't show and I rode 180 miles this past weekend in 39 degree weather. On the interstate cruising at 80-90mph oil temps were reading 125 and 150 at most if you stopped at an exit. The sensor is mounted in the pan maybe all the cool air was blowing on it and making it read inaccurate
 
Found a pic this weekend that shows where I located my oil temp sensor.

Here's a bung, which is a direct bolt in for oil temp.
