JET's 335Xi

[JET]

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!

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?

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

[JET]

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.

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?

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!

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?

:VP2:

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.

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.
