Hypertech speed calibrator problems

Anyone with a hypertech speed calibrator see this problem with the speedometer jumping every so often while driving a constant speed?

 

strangeness -- I've heard of others having the same issue over at TN -- I have one, but not installed just yet, so can't help ya there.

 

That would suck if it's true. I had a chance to return it to the place I bought it, but decided to keep it. Hypertech said they would do what it takes to get it to work. I guess I'll see what happens.

 

I just installed mine -- I'm definitely NOT having the same issues that you have. It seems to be spot on currently without any needle jumping. I've verified my speed via the OBDII port. I need to throw my GPS in there and see what it looks like.

Check your connections on the PCB and on the cluster. Maybe try reflashing the little black box.

 

is yours an updated version/new model by hypertech

 

Yes it was, I tried two units but both had poor results so I finally just got a refund. Maybe due to my vehicle they say? 6spd

 

any update on this?

 

I finally just returned the product for a refund after trying two different units.

 

Mine still works well

but I have an AT

 

good to know, i've been monitoring this thread, have an automatic too and been considering purchasing the hypertech calibrator

 

For those of you with larger tires who have installed the hypertech -- did it help bring down your rpms at highway speeds at all?
