This is a good supplement to Terry's notation that this feature is for those who are not concerned with long-term turbo longevity. While there are those out there that may not fully comprehend the inherent risks involved, I like the freedom of knowing the power is there should I choose to utilize it.

Same for me, the moment the oil temp needle twitches my flashers flash. Coolant warm up time was about about 3-4 min at 30F here in MI.

Just changed last night 3 Injectors and coded them via INPA, routed the USB cable through the glove box, didnt need to disconnect anything just lifted the dme tray upward and it gave me enough room to fit a cable through there, Updated to 2/7 firmware....Now time to do some dataloggin' when i get some time.

This is all true for the most part, but keep in mind, just because the tune activates doesn't mean the driver has to immediately start driving at WOT. I started using this feature and I just like the fact I get the full responsiveness and feel of the tune much sooner, since my commute is very short. I still try not to push beyond low boost and low RPMs until the oil temp hits 160.

Also, your pic is huge you might want to resize smaller.

switched to the new software today and was surprised. after some short troubles in higher gears, the car was pulling just amazingly forward.

even on 95 octane (euro-spec!) fuel, which was not working really well with the old software (i had to put it in the car because there was no other gas station around...), the pulls on map5 made me smile BIG time!

Wheelspin in 2nd over the whole range + also spinning in 3rd gear.

the new possibility to enable the tune in dependence of water temperature is on one side quite nice, because it takes a lot of time to get the oil to temperature with low rpm, but on the other side it somehow feels so wrong to step on the floor without seeing the oil needle moving. i think it takes a strong-minded driver here that thinks about the possible consequences...

Loaded up 2/7 everything and tried map 5 for the first time. WOW. I'm very impressed. I was on map 2 and getting some really weird things going on in 3rd-6th gear up here at 6,200ft. Map 2 may have been a bit too aggressive for this altitude, without dp's. I am running the equivelent of 93/94 octane, so it ain't the fuel.

Anyway, map5 seems to be pulling like a raped ape in all gears, and much smoother as well. Very happy.

Ok, 7-2 loaded, map6 is simply amazing.
Never heard something like that before, and i've tryed all tunes with all maps (aggressive included).

Many compliments Terry, some logs will coming.
PS: only one thing... i've noticed, when jb4 turns on, a little "pull back" (i was at steady throttle and i've turned on blinkers)... Just a little hesitation.
PPS: only the first time... never happened after that.

I thought JB4 won't get activated untill the oil temp hits 160?

By default that is true, and it is the recommended setting. But you do have the option to use the coolant temp instead. A few members requested it because they lived in a very cold climate and understand the consequences.

Amazing... Terry, simply AMAZING.
Every time I push WOT it's incredible. This map6 is really awesome.

Well, it's italian fuel pump 100RON.
Consider that usa's 91 is our 95RON, and usa's 93 is our 98RON...
So about 94/95oct.

How safe is map 8? I mean if I drive on that 5 days a week and wake up the turbos on the weekends, is that safe for turbos to just sit there. How about map 8 for long cruises when I just wanna feel what a 328 feels like?

Perfectly safe long term as long as you don't mind the CEL on the dash.

I've got a long drive coming up this weekend. Thinking about seeing what the range difference is for a tank of gas between maps 8 and 6. I'll keep you guys posted!

I wonder, could you use 87 octane on map 8? Maybe that's going a bit too far to save money

Thanks for the help in advance.

Once you switch to map 0 your car will have to relearn on map 5. Not saved.
Auto tuning does not learn in 2nd gear. From my experience even a conservative Map 5 will spin at the wheels in 2nd gear. Therefore the JB4 will not learn accurately in 2nd as you wont get a full launch all the way up to redline without the wheels spinning. I find using only 3rd gear to learn works fine for me

How many 3rd gear pulls would you suggest I do for Map 5 to learn?

I think Terry mentioned somewhere that 3 pulls should do it. You should notice the difference before and after.


Cool stuff no longer installed.
