Anyone know how to do this, Also how to lower fan on temp.
I am using Flash n Burn. and TunerProRT.
In Tunerpro, just raise the Temp for the EGR to open to 255....never opens....same with the air, only it's in several places...you'll want to mover the temp up on some, and down on others....to lower the Fan temps, look in your Constants, and scroll thru the list, and you'll see the Fan adjustments...two for normal {Fan ON Temp, and Fan OFF Temp}, and a set for when the A/C is on....just set em' to what you want.......
I know what basically what has to be changed but I need specific lines.
Here are the default values:
Minimum Fan 1 Time On n 1 Time On
Fan 1 Turn On (A/C On) 225.95 Deg F
Fan 1 Turn Off (A/C On) Fan Deg F
Fan 1 Turn On (A/C Off) 225.95 Deg F
Fan 1 Turn Off (A/C On) 220.55 Deg F
EGR Enable if TPS >x & EGR Duty Cycle!=0 5.86% TPS
EGR Enable if TPS >x & EGR Duty Cycle=0 6.25% TPS
Disable EGR if Mat < X 0.50 Deg F (255 goes here)
DFCO is decelleration fuel cut off. I don't understand your question about the fan temps? Double click on the fan temp on/off and adjust accordingly to a temp of your choosing. I use on at 200 off at 185. Change the temperature of Disable EGR if MAT to 305 or something outrageous and then your done with the EGR changes. The other 2 tables are not used at that point. Might want to do some more reading at the www.thirdgen.org DIY PROM. Great info and LOTS of information to digest.

Dude, I have read until my eyes bleed!! Nowhere that I have searched can you find a line by line that explains what all these entries are. Some of them you can figure out but most are a mystery. Excuse my rant, but I have read every word in Third Gen twice. What last two lines that are not used are you referring to and how do you know this? I have read about corrections made to O2 readings due to AIR states.
I don't understand your full post above? I'm not a mindreader but I'll give you a post on how to disable EGR if that is what you are referring to. Might want to make your eyes bleed just a little more....the info is on that board:

I'm not certain what part of the answer you don't understand so do I need to spell it out for you? I've offered help and your an azz about it. I've given the link that describes exactly how to disable EGR, I've told you exactly what has to be changed in the temps to turn your fan on at a temp of your choosing, and I also told you that emissions isn't used in the ARAP bin so throw out the window what you've seen about the AIR making your o2 voltage go down. I guarantee you didn't read a go*amn thing on www.thirdgen in the DIY Prom section as it is all there in plain sight. I'm not asking for a thank you for any info I give out as it is a self help board but if you want help you might want to change your attitude in the future. Do your own homework.....the info is there in the archives or by doing a search on www.thirdgen.org. I am no pro as I just started tuning myself but I'm pretty damn appreciative to the members of this board and thirdgen who have helped me. You might want to try to be appreciative yourself if you want to get anywhere on this board!

Minimum Fan 1 Time On: The amount of time the fan will stay on once it is turned on by either (Fan 1 Turn On) setting.
Fan 1 Turn On (A/C On): The temperature setting when the fan will turn on if the air conditioner is running. The fan will stay on until the temperature drops to the (Fan 1 Turn Off (A/C On)) setting or the (Minimum Fan 1 Time On) setting, whichever happens last.
Fan 1 Turn Off (A/C On): The temperature setting when the fan will turn off if the air conditioner is running provided it has ran longer than the (Minimum Fan 1 Time On) setting.
Fan 1 Turn On (A/C Off) 225.95 Deg F
Fan 1 Turn Off (A/C On) 220.55 Deg F
These settings work the same way as described above. The difference is only that the air conditioner is not running.
As for the EGR, if you set the (Disable EGR if Mat < X) to 255 the ECM will never activate the EGR valve. The other settings only get looked at if the EGR valve is activated. Since it won't activate after changing the above setting as mentioned, you can ignore the other EGR stuff because the ECM is going to ignore them.
Now for AIR delete. The air is only directed to the exhaust manifolds when the engine is warming up and in open loop. The O2 sensor is not used during warm up while the ECM is in open loop. Because of this, there is no need to worry about the offset for the O2. After warm up and ECM in closed loop, the ECM either directs air to the catalytic converter or diverts it to atmosphere depending on driving and engine conditions.
As for removing the AIR, simply disconnect and plug off lines at the exhaust manifolds and converter. Disconnect the 2 plugs on the AIR solenoid valves. Remove the AIR equipment if you so desire. There is nothing that has to be done in the .bin. You could turn the flags off for it, but you don't need to.
As a side note. There is a lot of debate about what effect the AIR delete does to the converter. I don't use the original converter so it wasn't an issue for me.
BTW, the fan turn on setting will always need to be higher than the fan turn off setting. You should also set both settings higher than the thermostat opening temperature. I use a 10 degree difference between fan on and fan off, and set the fan off a few degrees higher than the thermostat.

Thank you sir!! You understood and answered my question perfectly. Now, back to reading.
