Using the JB3 1.22, if I change maps do I have to allow the tune to re-adapt or will it already be adapted from the previous times i use the map.

So for example if i want to daily drive on the valet mode and switch to map 3 or 6 at the race track, will i be running the risk of not having the tune fully adapted?

Is this answer the same for all tunes?

GREAT question.

[cocoturkey]

subscribed.... I want to know the answre too.

Did you try asking on the other site?

+10000!!!!

Very Good question!!!

[mr_graphite]

I would love to know the answer to this.

From what i know you need to adapt the ECU for about 1000km (lets say map3) . After that if you switch to Valet drive around and switch back to map 3 only a couple of WOT are necessary .

would like to get a confirmation on this.

[bubbletea 4 me]

email Terry, afterall, he created the JB3.. it's great question though.

Can you imagine if my tune only white sedan had the seats removed? Running tune only it managed 117.54mph, with seat removal it would have been a record 118.54mph. That was one fast car! So these tests are on the coupe. You can see on most of the earlier runs with the 19" Generals, I launched in 2nd gear and still managed 12.8 sec ETs. Traction was pretty hopeless in 1st gear. (semi moist conditions?).

Secondly, a word on adaptation. I don't care what the dyno results may show about quickly switching maps and having an artficially high dyno output. My runs clearly show that they DON'T GET SLOWER, THEY GET FASTER, ON SUBSEQUENT RUNS! So I really don't see what the big deal is about map switching at an intersection. If you had to, the whole process only takes about 15 seconds. Secondly, at anytime during the process, if the light turns green, etc, you could start and leave right away. It's not like you are going to be stranded. But most importantly, why would you want to switch to a higher boost map unless you have a switch to summon up 100 octane fuel. And vice versa, if you are running on $7/gallon fuel, why would you ever switch to the lower octane map?? But most importantly, given that my car runs faster on subsequent runs...impromptu races and map switching are not ideal for maximum HP. Maybe its just my car??? LOL.

Secondly, the runs below are on the standard JB3 1.2 unit. (Not the turbomelter). Hopefully I can get some runs on the turbomelter today. Interestingly enough, you can see how switching to the Hoosiers dropped my 60' time from a 2.1 to a 1.9. And immediately, the .20 second drop resulted in a .40 sec quicker ET. 12.7 vs 12.3 seconds. I still can't launch with any significant boost, and these runs are done with absolutely no warmup burn outs. And yes, I could duplicate these times at the track as well as the Vbox in the same cold temps. Actually mid 50's isn't that cold.



Results of Vbox tests:

91 Octane. 19” Generals. Map#6 57F.

13.1 sec at 111.2 mph, 2.3 sec 60ft

Here are the tests with the turbo melter map 100 octane.

Same as above but 51F, Turbomelter Map.
12.1 sec at 117.2 mph. 1.9 sec 60ft. 1/8 mile: 7.9 sec @ 94.2 mph. 0-60 3.8 sec
12.1 sec at 117.6 mph. 1.9 sec 60ft. 1/8 mile: 7.9 sec @ 94.4 mph. 0-60 3.8 sec
12.1 sec at 117.2 mph. 1.9 sec 60ft. 1/8 mile: 7.9 sec @ 94.0 mph. 0-60 3.8 sec
12.1 sec at 117.5 mph. 1.9 sec 60ft. 1/8 mile: 7.9 sec @ 94.3 mph. 0-60 3.7 sec
12.2 sec at 117.6 mph. 2.0 sec 60ft. 1/8 mile: 8.0 sec @ 94.3 mph. 0-60 3.9 sec
12.1 sec at 117.7 mph. 1.9 sec 60ft. 1/8 mile: 7.9 sec @ 94.3 mph. 0-60 3.8 sec


As you can see, it is only about .8mph faster than map 7 tested.
FYI: The white sedan ran 118mph on the Vbox down here, with full weight! So I would say it was at least 1mph faster. (`10hp or more)

Also, with the automatic, launching in some ways can be more difficult than a manual. When launching with the automatic, too much wheel spin will cause the trans to upshift by itself, then when it grabs and you are flooring the throttle, it can down shift to 1st, and overrevs. Its very difficult to modulate the throttle without the trans shifting too early, or down shifting unexpectedly. Easily will ruin your runs. So many times I wish I had a stick, however I think it would take a beating on the clutch to get really great runs. I could show you some videos of the funky things the steptronic will do during a hard launch, and you won't see that happening on a stick shift.

Hope it helps

A few WOT runs will do it.

[bmwturbopower]

atleast 3 pulls WOT will do it.

[cu_north]

I'm so glad Hotrod did testing like this. It really makes me want to get a VBox.

Normally there is an adaption period of a few WOT runs between maps. Not a big deal for driving, but if you're planning on dyno testing do a few runs with each map for the best results.

thanks for the replies. Makes sense, at least now i know what to do with my 1hr time on the dyno.
