Uprev tune, now cruise control not working

seymore4 · 12-15-2016, 07:15 PM

Using the map switching feature has ZERO impact on the cruise control, it should still work exactly like before. If you got the ARC features as well it is possible that there is a bug that needs to get ironed out, but I haven't heard of anyone losing cruise completely.

Another possibility is that the tuner flashed your ECU with a rom that was from a Z without cruise.. so now your car thinks it doesn't have cruise either.

Long story short, get ahold of the tuner.

Hey guys. Finally went and saw my tuner today. (Alex at Real Auto Dynamics is the one who tuned my car. Great guy, great tune, and friendly, helpful staff.) My car was definitely tuned with a ROM for cruise control. Alex went through all the maps, then test drove it, but the cruise control still wasn't working. He then flashed the ECU back to stock, and the cruise control wasn't working after that either. He also called UpRev and spoke to the head tuner there to try and get some ideas/solutions, but to no avail. I can't say enough about the shop and staff at R.A.D. Great guys and I would recommend them!

It just happens that my cruise control coincidentally stopped working after I got tuned. I didn't even try using my cruise control for over 2 months, after getting tuned, so I can't honestly say when it stopped working - I just figured it had something to do with the tune. Anyone else know what else I can check? Like I stated in my first post, when you press the cruise control light, the light illuminates on the dash, but when you try to set it, nothing happens. I don't think it's the buttons for the cruise control, as they work when changing maps. Thanks again for all the help guys!!!
