I was testing these maps out last night and logged a 3rd gear (2,000 to 7,000 rpm) map5 vs map 2. Map 2 seems to hold a more constant boost.....map 5 may feel a bit more torque down low. I have the cvs file but have no idea what to even look for lol!

here is a 2,000-7,000 WOT run in 3rd gear map2 Vs map5 (Did 4-5 3rd gear WOT runs before logging so map 5 was adapted). I have the CVS file if anyone wants to read it. noticed on map 5 run it may not been at full throttle...
map 2: map 5:

map 2 vs map 5 with ignition and target...seems a bit under target on map 2 wich means a leak I am guessing. I have replace on lines on wastegate selonoids and canisters....lines behind oi housing...I am thinking Charge pipe O-ring or map sensor O-ring.
map 2: map 5:

you're barely underboosting in Map 5 so I wouldn't worry about it, i'd be more worried about why your log doesn't show 100% pedal in Map 5
Also, Map 2 looks too aggressive if you look at the timing drop according to the log. You shouldn't have a timing drop @ 5200 rpm, which looks like the car hit 12-12.5psi vs. 11.5psi in map 5. This could be the reason why target boost isn't reached. You may need higher octane to run Map 2 or take advantage of Map 5 autotune.

Because of the ECU timing an IS can run the old Map 2 with no bolt-ons but you need to be sure of the octane & Map 5 was a good solution. There also seems to be some slop or reaction time in the system since my Map 6 is pretty much 15psi through the rev range but shows the 17psi limit a lot on the oil temp gauge hijack. Have not gotten around to a dyno run or log on the new map but the car is definitely faster & one guy with my exact setup went fro 12.8 to 12.5 with just the Map change. I would expect all the 3/7 upgrades will help all the car across the board so it would be a good plan to download & install them. Word of caution do not try to run the 335is, 1M or Dinan maps on a 335i because the factory installed timing curve is a lot different & you will have problems. It would seem to be a good solution for anyone who is mixing gas. A no bolt on regular 335 with 91 octane has two choices 1 & 5. A down piped regular 335 has Map 2 & 5 as a choice on 91 or better. Either map will give more power on 93+ BTW I think Map 3 is a meth specific map have you looked into it?

I had no add-ons at all & got 365WHP on a Dynojet Map 2 94 octane so I would expect under the same conditions you would be at least +20whp. Thing is its not a good plan to compare numbers since conditions & machines vary all over the place. Key is a baseline run .vs. a modified run to see what you are really getting. My pure stock base was 314whp. I have since added a 5" ETS FMIC but have not tested the car. The FMIC was more to deal with the summer heat then to add any power, but more power would be frosting on the cake.

I'm not sure why you're experiencing timing drops with the mods + 93 octane. B

Higher rpm so it won't kick-down? Log with ignition advance correct? Maybe I got crappy gas?

I'm not sure how to by-pass the kickdown for the automatic trans. I suppose a log above 4,000rpm is best, just to see if there is timing drops to red line.

Log: 1) IAT 2) AFR 3) Timing 4) Pre-boost 5) Exp1 6) Throttle 7) Target send a .csv to terry if you're still experiencing the timing drop. He'll assist you very quickly.

What I have found that's easier to do when logging 3rd gear... Is to put the car into DS mode, get it up to 3rd gear, then start at a much lower RPM before pushing the peddle down SLOWLY without hitting the kick down... and if you start at a low enough RPM, you'll still be WOT before it reaches 3k RPM... Otherwise if you try to start at a higher RPM and quickly stab the peddle, its more likely you'll hit the kick down.
And as for logging and sending .csv files... The JB4 logs everything every time. So when you send someone a .csv file, everything is already there for them to see if they choose to. Clicking the options on the logging screen only selects what you actually see on the screen. Go ahead and try it some time, open up an old .csv file with the JB4 interface, and click on any option you want to see and it'll all be there, no matter what you had selected when you did the actual log But obviously if you want to show a picture of your log, you'll have to select what you want them to see.

If you can't get your timing drop resolved, you could always try the CPS module to assist with that drop @ that RPM
It must be an elevation thing, I'm at or below sea level here (+/- 50ft) and I can run Map 2 with just a drop-in + 93 octane and get a healthy timing curve. It's only when I run higher than 17psi (map 7 or Map 3) is when I get a timing drop (even with Meth and race gas mix) so I keep it safe at 16.5psi and always get a healthy 4th gear timing curve.

I was just informed by. Ver knowledgable person that DCT should be turned off while logging....mine wasn't. I thought DCT just loosed wheel spin and did nothing to timing....I was wrong lol!!
