I would like to make a plug for the econ map 4 and the exhaust flap bypass as well. Also, adjustable/lower stealth gauge hijacking (50%?).

Couple questions:
- Would you expect the new "economy" map 4 to yield much better fuel economy for highway driving than stock/Map 1? Do the turbos even produce boost at cruising speeds on stock/Map 1 mappings? (maybe a silly question, but I am no FI expert)
-Would you expect the final Map 5 to produce more power/boost on all stock cars than Map 1 (93 oct)?

FWIW, I noticed about a 5 mpg spread between Jb3 map 0 and Map 5, all highway driving approx 400 miles.

Hey guys, uploaded 2/21 firmware:

1) Revised map 5 algorithm from 0-20 steps down to 0-15 steps but with each step representing more of a boost change. Resulted in improved stability.
2) Lengthened window for increasing aggression 15%.
3) Revised map 1 to include a little more high rpm taper based off customer provided logs.
4) Fixed bug with aggression level resetting when entering command mode even if no map selection change is made.

Entirely possible. It will all very much depend on how close a fit map 2 was to your car prior.

I also felt like its faster than map2 ,throttle response is HIGHER...

i was running on map 2 ,i did some WOTs but the ffmax didnt change (=100) ,isnt it supposed to change?

I am now running map 5...lets give it some more time to adapt...

I noticed that as well. After I updated to 2/18 the ffmax value was still 51. I changed it to 100. I thought it would change automatically with new firmware?!? Will try to run a log tomorrow.

I understand map5 is safer due to autotune, but what about a scenario where it tunes to 16psi one night, and fuel or weather conditions suddenly take a turn for the worse after a morning refill? It does not learn until WOT high rpm 3rd and 4th gear runs, so what if a user unknowingly burns through first and second with unsafe autotune intervals set, when their "safe zone" is really only 12psi?

It is a non issue at part throttle I would guess because the DME is constantly monitoring things and making adjustments.

yes, we dont reach full boost at part throttle, but there (although seemingly unlikely) are people who may WOT in first and second and hit the autotune 16psi target unsafely, no?

Terry - How long would it take to adjust back from 16 psi to let's say 12 psi? Especially interesting to know if we don't use the same gasstation all the time.

It will change itself if needed. The 100 default value we used was an average based on many cars so it's going to be very close in many cases.

1st and 2nd gear are not at all knock prone so there isn't much of a concern there. Besides I think people take the "safe zone" a little too literally. We've had customers running JB3 map 7 tune only with 2-3 major timing drops per gear for YEARS without issue! So a drop here and there is not an issue at all.

The algorithm is quick to drop boost and slow to raise it. You could get from 16psi down to 12psi in 10 seconds of WOT, but to go from 12psi up to 16psi would take a minimum of 50 seconds.

That was fast, I barely had time to data log the 02/18 firmware. Can't wait to try it out.

Safe on map 5 - autotunes down to 12 psi which is lower than map 1 for stock cars. I have been driving on map 5 for some days now and it feels great - powerful and smooth Using 98 V-power, DCI and DP's. It takes a couple of days before it's fully adjusted though when you switch.

I Like Maps 1&2 with their aggresiveness and the power on tap, but I am really starting to like map 5. Very progressive and adaptable. I was mapswitching on the way to work this morning and you can definetly tell the difference.

Now to update and do some logs today!!!!


Autobahn.......its what's for dinner!!!
