gauge used to limit at 5.5k and now goes past 7k

[Faviolosky]

like it said, from morning to night the cluster was working fine and limiting at 5500 rpm, but something happened and now it goes way past 7krpms, wtf. please help

Umm, well first step would be to not rev it up that high, even if that has happened. You're going float your valves, hit a cylinder, and demolish your rockers.

Otherwise, you have a problem with your rev limiter, which is controlled by the chip IIRC. Try swapping in another ECU and seeing if the problem persists.

no its not the right rpms though, my eta used to do 60mph at 2k and now it does it at 3.5k according to the tach. im not dumb i know ill get valve float. but its not the right reading. and i swap a different ecu and problem persists. its not a problem of the ecu.
it happened once before with another cluster too.

Well, from your first post you make it sound like it's no longer physically hitting a rev limit.

mannnn i got it, i had switched coding plugs so that both my coding plugs matched, the obc and cluster. and coding plug was from an eta
old plug is back and working like it should

kronus is that greek , or is it Cronus the Titan but with a K, cuz then it will be kronos.

I was just about to suggest that it was a coding plug issue.
Also, you never mentioned that you actually did anything to the cluster. That might have helped.

[Faviolosky]

tru, but nobody asked. and i didnt know it influenced it.

You swap clusters, your reading gets all messed up, and you don't think that swapping the cluster could have anything to do with it..?

Trouble shooting 101 guys, what did you recently change when the problem started happening.
