I still havent fixed a few light sensors on my car. I have a check engine light from having the the post cat 02 sensor removed. Im not worried about that because I can tune that out tomorrow (unless this itself will be a problem). Does the ecu recognize the sensor not there and adjust the air/fuel ratio like older cars. Or if it sees an error does it compensate for it? What im really worried about tho is that once i get the tune however ill have trouble calibrating the tpms on my tires. I still havent done that yet Basically what kinds of things can I no longer go to the dealer for once I have ecutek?

 

Don't think you can turn off the rear 02 cell with EcuTek, not yet atleast. You need to do a mechanical fix using spark plug anti fowlers. Why do you ahve the sensor removed? Should not run any different with the code set.

I have no idea what you are referring to in regards to calibrating your Tire pressure monitoring system? Are you talking about having new tpms units programed to the ecu?

You could just remove the tpms units and store them in a sealed, pressurized, tube in the trunk of the car. Not the most elegant solution but it works and you non longer have to worry about the added expense of having multiple sets of tpms units for multiple sets of wheels.

Lemme check with EcuTek and my wheel and tire guy and see what he says about the tpms units.

 

Just spoke with my wheel and tire guy at Gran Turismo East.

DO NOT take this a gospel as he is still trying to confirm this is true for the evo. Typically, all you have to do is activate the sensor with a remote tool, then when you power on the car the sensor pairs with the ecu, no ecu programing is required. I would assume this works somewhat like bluetooth in that the ecu goes into paring mode at key on and looks for a signal from the tpms sensors.

He is also looking for some less expensive after market sensors that will work with the evo.

Hope this helps.

Unfortunately, this does not work. It has been tried and failed. The problem is that the sensors get their power from kinetic energy like wrist watches. Unless the tube in the trunk can spin around, lol, it's not going to work.

As far as the post cat O2 sensor... It has nothing to do with tuning. Only the front O2 sensor does. The rear O2 sensor only monitors catalyst efficiency.

 

[QUOTE=Thegame;5904165]This is good to hear! I will def tune out the second 02 sensor then

 

[QUOTE=BluesunsXIV;5904451]Nothing to tune out, it has no effect on how the car runs, but It will throw a check engine light if you do not do a mechanical fix (search in the 8 & 9 sections for details). and you will not be able to pass emissions when the time comes if you live in an area that does OBD-II inspections.
