Oh, and by the way, it took about 30 seconds to load the map ! |

Yep, but now i can't help but wonder why it took so long to load the map in the bike to PC. Maybe it was just a glitch and next time i try that it will be quick, who knows. But i really don't need to do that anyways. As long as i keep any map that i can't get online or remember any changes i made i will never have to do that for any reason i can see. So like you said when you did this....man, that was easy ! I'm really starting to become interested in how it all works now. Not a good thing tho ! Knowing me I'll end up trying something i shouldn't and blow my bird's engine.

| | Posted : 30 Jan 2011 - 14:15 Post title : Re: power commander released (Re: EnGage) | | | All I'm finding says that what we are doing is not harmful. But, what would be harmful?
Running with Boost setup. If someone turbo/super charges, they have to run really RICH.
That will kill the cat bed and may engine gunk the sensors.
This says specifically that simply not using the sensor is OK, if you aren't trying to dump enormous
load un-burnt fuel down the pipe.
What will damage my O2 sensor?
Home or professional auto repairs that have used silicone gasket sealer that is not specifically labeled "Oxygen sensor safe", "Sensor safe", or something similar, if used in an area that is connected to the crankcase. This includes valve covers, oil pan, or nearly any other gasket or seal that controls engine oil. Leaded fuel will ruin the O2 sensor in a short time. If a car is running rich over a long period, the sensor may become plugged up or even destroyed.
Just shorting out the sensor output wire will not usually hurt the sensor. This simply grounds the output voltage to zero. Once the wiring is repaired, the circuit operates normally. Undercoating, antifreeze or oil on the *outside* surface of the sensor can kill it.

READing takes much longer. You get the entire map set, bit by bit. This is the true, unique beauty of TuneECU. You READ your own
map that came from your bike. It's in Hex, not wrapped with a 50% .dat overhead like some other brands.
DOWNLOADing just updates the differences. Quicker.

| | Posted : 30 Jan 2011 - 14:59 Post title : Re: power commander released (Re: DizzE) | | | Heres another answer i got, and i think this guy may have just nailed it. If he's right then our question now is whether or not unchecking the sensor boxes in the map turns the sensor heaters off or or not. I emailed Alain, but he may not even know. But i think any info you found on them needs to be determined if they are talking about heated sensors are not, right? Because if i recall didn't you say these are lambada (or something like that) sensors that are heated but some older ones are not?
If you unplug the sensor you will in addition to the signal wires, cut the sensor heating circuit off. A sensor without the heating will not burn off carbon.
I have not doublechecked if just turning the sensor off in TuneECU will turn off the heating also. It might be that it is still heated, but just the signal is ignored by ECU.

| | Posted : 30 Jan 2011 - 15:47 Post title : Re: power commander released (Re: DizzE) | | | Of course. But do they need to be self heated to avoid this, exhaust gasses aside. Thats the question. This guy is saying just that so i can't discount that possibility. With tax the sensors are going to run close to $400 so i want to be safe.

Up to you.....I think un-supported opinions are just that. There is plenty of info to the contrary.
Link Getting Hot
--------------
Something else you need to know about O2 sensors is that they have to be hot (617 degrees to 662 degrees F) to produce a voltage signal. It may take a few minutes for the exhaust to heat up the sensor, so most O2 sensors in newer vehicles have a built-in electrical heater circuit to get the sensor up to temperature as quickly as possible. These are usually three-wire and four-wire O2 sensors. The single- and two-wire O2 sensors are unheated.
If the heater circuit fails, it will not affect the operation of the O2 sensor once the exhaust gets hot but it will delay the computer from going into closed loop, which may cause a vehicle to fail an emissions test.

| | Posted : 30 Jan 2011 - 18:11 Post title : Re: power commander released (Re: DizzE) | | | Well, theres this. But you could interpret it several ways. I guess in all likelihood it means the time beteen startup and when it gets hot enough is when they are susceptible to carbon buildup, but who knows. The tbird could be different than cars, and reading that article gives me the impression cars use wide band sensors. I think i may try enabling the sensors and if it still runs the same.

| | Posted : 30 Jan 2011 - 18:56 Post title : Re: power commander released (Re: daz) | | | Well, let us know. I'd be inclined switch them back on, as well. Hmmm., the time it takes to heat up, before it begins to control
it's environment. Could this be a problem? 
I'm sure we both realize that if that's true, it's because they've been designed within those tolerances. Designed so closely, that
they can't be exposed to a rich starting condition (which this map doesn't have, btw)
Even the 15 mins. it takes to warm in the exhaust? Could be.
IAC, wideband is different. Some of the latest, low rev tuybo cars have those. Most cars don't yet.

I will, tho of course it would rain today for the first time in a week or 2. So i sit here bored instead. As Al Bundy would say, "ARG".
