Frequently Asked Questions

Q. Why don't you Install the Accessport before sending it out to me so I don't have to do it when it gets here?

A.There are a few different reasons for that.  One reason is that we don't immediately know what map you want to flash, whether your car is stage 1, 2 or should really be on a custom tune.  Another reason is that while we do testing here to make sure everything works, we only really see what is going on with the ECU itself.  In order to make sure everything is working properly on the rest of the vehicle we need to do the flashing on the car.  This is important since you could potentially get stuck on an incorrect map or something on your car (aftermarket electronics or damaged wiring) could block communication with the Accessport, and we'd rather find those things out as soon as possible.


Q. What happens if the ECU arrives damaged?

A. If there is physical damage to the packaging or ECU when it arrives either at COBB Headquarters or at your front door our first step is to let you know, likewise your first step should be to get in touch with us.  Each of the packages are insured through UPS and we promise to do everything in our power to get you going again as soon as possible.

Q. What happens if it can't be programmed?

A. While rare, in some instances the ECU may not be physically damaged but may be defective enough that we are unable to flash it.  If for any reason we are unable to perform the backdooring process we'll reach out to you and let you know as well as give you options specific to your case.

Q. What if my ECU has previously been tuned

A. While things can always change in the future, at this time we are able to flash over all known competitor flashes.

Q. Can the Dealership tell it has been flashed?

A. At this time, yes.  It's very likely that the dealership will be able to see this, so if you're concerned about warranty or racing bodies being able to detect the flash, you may want to wait until we've further refined the process.
