I think you are trying to write the wrong file or your version is outdated. I will be back from florida next week if you are still having trouble but try checking that you do have the latest version installed and that you're opening the file I sent then connecting and trying to pick write calibration.
I got the new tune installed but my car is running like crap It is I think i'm not getting the rear o2 sensors turned off. I opened the tune unchecked the rear 02 sensors saved it then wrote the tune to my ecu but I don't think they actually got turned off I left the heaters checked. can you please explain exactly how to turn them off and how to make sure it is actually applied to my ecu
Turning the rear O2 sensors off simply ignores the input. The heaters are not run independently so you can't turn off the rear o2 sensors and simply remove the physical sensor because the front ones need the heaters to work properly. Is your car giving you an engine code?
i have them installed in the cat delete pipe. was going to use spacers but cranswick said not to and just turn them off. I attemped to turn them off but I don't think it worked. I am getting a code it said something about random misfire. after installing header and deleteing the cat it ran fine for 15-20 miles then I got the code and it started running bad. I cleared the code unchecked the rear o2 sensors saved it then wrote the new tune it runs just like it did before the tune and I am getting the same code
on the original tune I got p0300 random/multiple cylinder misfire detected and on the new tune I got p0300 and p0175 system too rich (bank 2) I drove it a lot farther on the new tune so that might be why I never got the p0175 on the original tune
The rear o2 sensors are used to monitor the cats. So changing them won't have any impact on the system too rich/lean or the misfire codes. There are some cold air intakes that don't behave particularly well so I have developed a few fixes for them, especially for cars I have tuned in person or those with wideband o2 sensors installed. If you'd like send a request with your latest file to email@example.com with a list of your mods and I can check it against my collection of tuned files to see if I can give you something better.
