Surging with Range device?
 

So, I tried my Range device for the first time last night. I don't have any TC issues yet, but I wanted to be proactive.

I definitely did notice a difference, but I'm not sure I liked it. I drove both in town and highway, using cruise. It seems like the car wants to surge just slightly and only for a split instant. I don't know if this is the car wanting to go into V4 mode and the range catches it and prevents it or??? That's almost what it feels like. Has anyone else noticed this?

Shifts also seemed more pronounced in every gear, especially the higher ones like 7th and 8th. It was the slight surges that annoyed me most though.

​​​​​​I searched this and found nothing. Thoughts?

Yup, straight from Range.

I literally ordered straight from Range. Learned the hard way on that one as my last came from Amazon and was clearly the older version.

I don't have any issues with mine at all. If anything my shift points seem smoother with Range plugged in.

Yes, I too notice a little surge with the Range plugged in, but not really an issue with me....

OK, I'm glad it's not just me. It's like a pulse surge. Didn't really even notice anything on the tach associated with it either, but it was there. Both my husband and I could feel it.

Yup, exactly what I feel.... Don't know why....

When does the surge occur, when tranny changes gears or after you are in whatever gear and cruising or when you first put in gear? I haven't experienced this and I bought mine from a forum member and sent it back to have it upgraded to latest version free of charge. Very happy with range and service.

Ok, got a chance to drive it again. Definitely a bit of a surge and even the exhaust note changes. This is with cruise on the highway.

However! I changed the display so I could watch what mode it stayed in... 3 times I caught it go into V4 mode. Once coming off the highway, once coming to a stoplight and another after a turn from a stoplight. So, me thinks I need to talk to Range about this.

I suggest you unplug the unit, plug it in again, and take it for a drive. It may not be seated good into the port.
If that doesn't work givee em a call, they're good folks.

Yup... Already did. They gave me reset instructions to try. I'll see if that does the trick. It's definitely not normal. I ended up pulling it today because the hesitation was getting really annoying.

I hope the reset works for you. Keep us updated.

Will do! Thanks Rebel :)

I've put a few more miles on mine and today almost 200 miles in Tour mode and mostly 7th and 8th gear and they were consistently smooth shifts. I had one slightly rough downshift when coming to a stop but I had those before too. I'm very happy with my Range. No problems whatsoever.

It should never go into V4 mode with the Range plugged in. Are you using a switch or directly into the OBD port?

Well, I tried Range's reset instructions and it was still popping in and out of V8 mode. In one mile it did it 3 times all at under 40 mph.

It is plugged directly into the port. That's hard to screw up. The connection is tight. I'll have to call them again tomorrow and see where to go from here.
