JET's 335Xi - Page 5

**cmspaz** · 03-19-2014

That's not bad, the Yedda gets 25-26 in traffic.

**JET** · 03-19-2014

I get ~21.5mpg on my commute, but it is all back roads with lots of stoplights and only 13 miles long.

rose0529 · 03-19-2014

It's a bit early for me to say but I hit 28ish on the way home from Boston, the stop and go in Chi-town killed a tank down below 26... and got 21 on my last tank of commuting and "enjoying my new car"

Here is my fuelly.

Little update: MPG's still over 2 MPG improvement still. I repainted the steering wheel trim that was pealing. Changing the fluids to Redline D4 seemed to make no improvement in shifting from the OEM, in some cases it has made shifting slightly harsh in some gears. Id say the OEM fluid is still the best option which I will change out too after the next oil change.

In other news I hit a giant ice chunk on my way home and destroyed the engine splash shield and cracked the paint on the bumper. The impact was enough to ruin one of the TPMS antennas in the fender well as a result, the tpms light is displaying Inactive in the dash. Doah!

More improvements to come. I have new set of Michelin Pilot Super Sports sitting in the garage in 235/40/18 and 265/35/18 sizes.

TPAL!

On a side note I have picked up about 1mpg from the tune also. I wasn't expecting that and I tend to get on it more also. I have a dealer visit in about 1k miles just for an inspection, then when I put the JB4 back in I am putting the flex fuel wires on and will start running E40. That will be plenty of octane to max the turbo. That should put me around 360whp. You can gain about 20whp from the FMIC and DP total to get to 380whp at it is completely maxed.

I might get an FMIC this year, but won't be doing a DP until the warranty runs out probably as they are a bitch to change and they could use it as an excuse to void warranties. The FMIC is going to be hard to prove that is could do anything to void the warranty. I will probably also do the trans flash. On a side note I found out my car already had a JB4 on it previously. Not real happy about that, but I figured it had a tune. The person that spec'd the car was obviously an enthusiast.

**JET** · 04-21-2014

Service appointment is scheduled for next Tuesday, so flex fuel wires will be going on shortly after that. I should be sitting at 360whp once I get the E50 in it.

Well I sold the AEM from the talon so I have some more money to play with. I should be able to get all of the visual mods done that I want to do. That will probably be all I am doing to the car this year. I will be painting the portion of the diffuser that is flush to the body and leave the rest black.

Boring stock diffuser.

rose0529 · 04-21-2014

Does this replace the whole bumper or just diffuser?

**JET** · 04-21-2014

Just the diffuser. M-tech only as the others don't have a separate diffuser. $275 but shipping is high at $95. It is sad when a Kia has a more interesting diffuser than the stock one!

**JET** · 05-01-2014

I got my car back from the dealer last night. I put the flex fuel wires in the harness and I will be switching to the higher boost autotuning map and adding ~E40 tonight! I am excited! Dyno day on Saturday at MAP, so we will see what she puts down. Any other BMW peeps going on the short cruise/dyno day?

I might make my way over there since it is a stone throw from Hastings. The car has a case of the cold start misfires but runs fine when warm. Interested in the autotune stuff, any idea what the high boost ends up being on ethanol?

**Kracka** · 05-01-2014

So you will be custom blending at the pump? Too bad nobody around up there or down here has the blender pumps.

**JET** · 05-01-2014

Yeah, I haven't found any blender pumps around this area. I will be filling up with 7 gal of e85 and 8 gallons of 92. No stations that offer E85 and 93 oct in the area either. I did find 2 stations next door to each other that have both but it probably isn't worth it for the boost I will be running. The turbo can only put out about 21 psi in the mid range. E20 would probably be enough for me.

**JET** · 05-01-2014

I should peak over 18psi, but it falls off hard over 5500. I think the map 1 I am running right now maxes at 12.5psi. I am expecting much horsetorques!

EnjoyDriving · 05-02-2014

Wow, I'm glad that Rosey/Spaz told me about this thread!! I should have come over this site a bit more. Didn't know that Shawn and Rosey both got into BMW as well. As for me, sadly, sold my IX a week ago. But, surprisingly, I might be picking up a 2011 335xi coupe soon. If the deal goes thru, that'd be funnnnnnnn.

For JET, yes, JB4 MAP 1 is set to run 12.5psi max. Maybe you can try the MAP 5 and see. Here is more about the JB4 http://www.n54tech.com/forums/showthread.php?t=13189

Shawn, your misfiring problems could be due to the well known HPFP issue N54 has been suffering. In fact, some of the early 2011/N55 might have that issue too. :-(

Well, I will pretty much follow JET's modding path
1) BMS Oil Catch Can
2) JB4
3) DP catless (lucky we live in MN)

By the way, do any of you know how to code the "auto window/sunroof rollup"? I must get the "auto mirror folding", not sure if Motorwerk would code them though?

**JET** · 05-02-2014

Yep, I switched over to map 5 yesterday when I put the E85 in. I haven't had much of a chance to get on it (I will tomorrow), but it definitely feels different. It pulls harder, but the newer software doesn't hit quite as hard. Easier on the drivetrain and still pulls really strong. Looks like map 5 can go up to 17psi. I might have to tweak the map more later and get a little more boost out of it. Seeing how I am Xdrive and 6AT, I will probably put down around 340whp tomorrow at MAP. We'll see soon!

Oh, I am not doing a catless DP until my warranty is up. Just to big of a possibility of them denying my warranty. Just put my charge pipe (UICP) on tonight, no performance gains but the stock one is plastic and likes to break at higher boost levels.

**JET** · 05-03-2014

Well I dyno'd today and the AWD system eats up more power than I thought it did. I searched for more stock #'s and 255/272 seemed pretty common for Xi's with an AT. Looking at that I got a pretty good bump in power, 306whp and 399wtq (one run had a blip to 408, but it was an anomaly). There was a DCT RWD car there with JB and downpipes and he put down 344/365 I think. I wish I would have been thinking and logged my runs. I just got the tune in and hadn't logged anything yet. Not bad, but I definitely need a bigger turbo.

3.0L love 67mm turbos, just saying.....
