Znod suggested I mention some of the features of the Gtech RR meter that I opted for and he is going to upgrade to as well.

I liked the Gtech RR specs and software features and the whole Gtech web site seems to be very professional and tailored to "performance" use of its products
I took a look at their forum and it has some activity but not as much as I would have expected or would like to see.

Some of the features I noted:

Rollout settable from 0-16 inches in 4 inch increments (plan to set at 12?)
Store up to 30 runs, with selectable delete
Can measure to any desired speed, will store all intermediate data up to 1/4 mile.
In dragstrip mode captures 60 ft time, 330ft time, 0-60 time, 1/8 time and trap speed, 1000 ft time, 1/4 time and trap speed (will omit any measurements not collected if less than ? mile)
Graphs RPM which shows shift points, time and duration, etc.
Graphs of speed (MPH) vs time in 10 mph increments,
HP graphs vs time.
RPM not required other than to get only RPM Related things - shift points, shift timing, etc.
You can set up special 0-xx-0 runs if you like without doing 1/4 mile runs.
PASS software for running on computer to collect and analyze data.

Here are some meter display shots (3) from manual (remember, mine is coming still and not in my hands yet). Also fuzzy pic of the PASS analyses software used in the dragstrip mode. Also has a road racing set of software analytical tools

This ?ol geezer still loves his toys.

Maybe 20 broke your DSC/DTC. I wish it had broken mine. I hate the idea that if I start with about the right amount of wheel spin, then the Step is likely to shift way early--producing a dead spot. The effect, at that point, is like having DSC/DTC on off the line. Ugh! I think your car needs new tires. And, I hope my car is just a slow learner. I understand about the PM.

If they broke theDSC/DTC it's going to stay broke.No more updates for me.I didn't want 20.01 but they replaced a computer module for the adaptive headlights and said it was necessary to reprogram.

Your right about me needing new tires.They work very good in warm weather but are terrible when cold.Probably will change at about 30000 miles,presently at about 19500.

I had a similar problem with early shift but was due to excessive wheelspin causing engine to go to 6500 at very low speed.

Thanks much cd. What did you mean by the bold in:

"In dragstrip mode captures 60 ft time, 330ft time, 0-60 time, 1/8 time and trap speed, 1000 ft time, 1/4 time and trap speed (will omit any measurements not collected if less than ? mile)"?

A little bit off topic . . . how you get a wheelspin on a steptronic without brake torque and dsc/dtc off? Either I have a lazy foot or my car is lazy from the start. Maybe my tires need to be worn in? What gear and what rpm does the wheel spin start on the step tranny?

Hi B32

Before 20.01.00, I almost always had significant immediate wheel spin in DS on reasonably good asphalt surfaces. So, the spin occurred in first and almost immediately, although I am not quite sure exactly what the RPM would have been. Now, I only occassionally get wheel spin, and it never is excessive--as it often was before.

Hokay. As predicted my Pro RR arrived today, and I am doing some reading. I presume the setup will be very similar to my ex Pro SS. However, I won't be using the RR on my 545i for a while. Tomorrow morning I am thinking of going to a test track at a local raceway. It is possible to do a full 1/4 there. I am planning to do a 1/4 both ways using D. I might as well get the bad news. I might follow up using DS, but I think that my car experiences the heat-sink effect when doing too many runs in a short period of time. So, it probably would be better to go back the following day to try DS. I have not made a firm commitment here; I'd have to get up pretty early.

Simply that the item will be listed but be all "0" if u aborted early from say a 1/4 mile attempt. If you get to 60 MPH and then backed off it place all a 0 value in any time or distance you did not reach after 60 MPH.

Thanks cd, from one "ole geezer" to another.

With DSC/DTC off I can get tremendous wheelspin with very little effort.Even if I am already moving in first gear when I go to full throttle the tires go up in smoke.Of course I do not have sport package so I have less agressive tires.When the weather is warmer(above 55 F) the wheelspin is much less and is controllable.The Goodyear RSA tires are much worse for traction in cold weather.

Wow Znod I wish I had your dealer.My dealer is very helpful with problems and has treated me well.


Also it will be very interesting to see your comparative times with the Pro RR.

Good luck in your testing and keep the faith .There has to be an answer to your slower times.

znod

The site is flat and level. I am not too sure when I'll start using the RR on the 545i, but pretty soon. And, yes, I am interested in seeing how the meters compare.

There may be an answer for me, but I don't think that BMW corporate is very simpathetic. Apparently, their attitude is too bad our new software doesn't work well on your car, and there is no way we'd even think about letting you do a "system restore." On the other hand, I am convicned that my dealer will do everything it can, but dealers' hands get tied very quickly.

Thank you for the good wishes. I am not expecting much. I hope I can break 14.
