Relatively newb here, dont shoot! Has anyone figured out how to trick the ebtcm so we can have a taller on back? Ive been searching and haven't found an answer aside from removing the bulbs (not an option). We set the correct tire size in the PCM with the EFI live to no avail cuz the ebtcm I hear reads the difference in tire size/speed? Will a tech2 help? I just installed 295/45-17 Mickey drag radials on my OEM 9.5 zr1's and I have the stock 275/40-17 F1's in front. Any help will be greatly appreciated.

I dont belive there is any way to shut the bulbs off, all I know of is to pull them out. I just deal with them being lit up, had them on for 2 years now, dont even notice them now.

So pretty much just gonna have to live with it I guess? There's gotta be a way to have abs/asr and a larger rear tire. I'm going to make it my mission to find an answer. Any tuners out there with any insight?

Nothing you can do about it, just pull the bulbs out if it bothers you.

If your car is not a dd and you don't need abs don't worry about it. I had this problem last summer with my tires so I just kept playing with different sidewall heights until I got one the computer would be happy with. My car is my dd so I wanted abs.

Not DD but I hate to lose abs and traction control. Anyone have issues with the abs activating on its own due to this? Anyhow, thanks for the replies.

I know several tuners and they all say it cannot be shut off. You will have to live with it or put equal diamater tires on.

The way the wheel speed sensors calculate the ABS and traction control is very rudimentary. The tire sizes must be extremely close for them to work properly, otherwise the system defaults into disabling ABS and ASR/TCS. Unfortunately, that means you have to live with it.

When you go to a 9" rear you can machine and fit a reluctor from an 8.8 rear that has two more teeth than stock. It might be enough to equal out pulses.
