speedometer problem...
 

just noticed today that my speedometer is like 1-2 seconds delayed from what speed i'm actually doing. my RPD is right...but the speedometer isn't. it works...and is accurate...just delayed as hell...help? ideas?

normal. mine does it too, only worse since im at a higher power level. mine lags as much as 8mph that ive noticed.

yeah man that's what mine is...i wonder if it's just cause of tunes. so your rpd is right too? that's crazy man!

yea, i took a video once of the rpd and the speedo together and when the speedo was at 80 the RPD was at like 86. lol. i have no idea where that video is atm tho

yeah its completely normal. happens to my car also. if you look up my name on youtube youll see a vid of me doing a 60 pull from third gear. (i did it from third cuz i couldnt get a shot of the rpd and speedo and shift quick from second to third while holding the camera) when i do a 2nd gear pull its even worse.

yeah man i was doing a second gear pull to look at like 30-50 time and i punched it and nothing happened for like 2 seconds....while i was stuck in my seat lol...mind you i just got the car like last week...never noticed it till now. dah well! rpd it is :cssNET:

Cobalt.

oh, welcome to the site.

Maybe it's the rpd that's lagging

its been proven that the rpd is more accurate then the speedo. there are plenty of vids to prove it also lol

The speedometer is accurate it is just simply slow. Digital readouts such as RPD and Interceptors have no lag since they are instantly displaying the information.

There are several things on this car that have their readings "smoothed" and therefore lag a bit. RPM, speed, barometer, the fuel gauge, and Boost/AFR/KR on the RPD all come to mind.

is this laggy?

little 3rd gear pull - YouTube

no but i bet the speedo was lol. i hope rpms aren't laggy........

To clarify, I'm talking the RPM and speedo on the gauge cluster. The laggy RPM is what's always blamed for people messing up NLSs, for instance. Once they begin shifting "sooner" (from the gauge's point of view) then the problem is usually solved.

I don't believe my tach lags much, but I could compare it against my interceptor and see.

yeah, i've never noticed my tachometer lagging. but who knows, maybe it does a little.

Like so,



It's a Cobalt. You'll find something everyday that isn't right about the car.
