ya, i'm confused also... is the Accessthingy like the tune tool? i mean does it do the same thing only more? i haven't really read any clarity on this new tool.. i would rather have performance over sound.. i'm trying to find a way to get that and go faster!

It's nice that this one can read and clear codes and do data logging. Accessport is a great product... The dimsport unit just loads the tune onto the car. The only downside may be the Alta tune, I dunno if I'd trust it. RMW's tune probably has a lot more users who've helped make it a solid tune.

I apologize ahead of time if this is a dumb question. I'm having the dealership check out an issue I'm having with my Bluetooth / iPod software package next week. They mentioned that it might be a software "glitch". I'm not sure what they would try to resolve it, but when I've run into software "glitches" on computers I either try reinstalling or upgrading. Assuming they try upgrading, will this impact my tune at all? I don't see how the engine control unit would have any impact on the bluetooth software, but I just wanted to ask the dumb question for peace of mind.
Thanks in advance!

Thanks Dwight and SpyVsSpy. I'm definitely going to flash it back to stock before I hand it over to them, and I have no problem reflashing it later to put Jan's tune back on. I guess I was just wondering why they would even touch the engine software stuff when it's just the Bluetooth / iPod software that's hosed. Unless the whole thing is one big shared system. I guess I'll find out soon. I hope I can keep my tune *and* have working Bluetooth.

I believe you can reset the dimsport(not the same as a vin reset) which will let you download the new ecu that BMW may put on. Then send that to Jan as per the original instructions.
This was discussed in an earlier post in this thread. Someone else got a new ecu upgrade and asked wether or he/she should put the tune back on.

Hey guys, I am going to one of Jan's custom tuning sessions in October and have a quick question. I have been thinking about getting a 2.5 inch custom exhaust set up, basically like the one BostonR56S has, and was wondering if doing it before instead of after the tuning session would be better for my tune. Also, I will be keeping the stock DP.

But no, I would abosolutely do the exhaust before the tune, as parameters will change with more exhaust flow, fast turbo spool etc, which he can adjust for on the dyno. If you have a more restrictive exhaust, air fuel, timing etc will be compensated for in different ways, its like 2+3=5, if you change "3" to "4", it will = 6, not 5. (another terrible example =) trying to work with lamens terms here lol ::flamesuit on:

My suggestion if to uninstall the AP, if you have one, or flash a stock map back on if you have the DimSport tool.

If you had an amputated leg, and were going in for rehab, would you put the prostetic leg on before or after the rehab? (lol TERRIBLE example, it was literally the first thing that popped in my head), sorry. haha

If a tuning device is available with access to multiple tunes for different combination of parts that can be used at anytime, then there is no worry about getting the part before the tune to save cost in the end. The tuning tool can be purchased first giving great power up front w/ the flexibility to add parts on down the road for more power all while having a tune available for those parts. The AP happens to have this ability. My suggestion would be to get a AP before any hard parts.

The Mini ECU is highly adaptive so the idea of putting on an exhaust first seems sound especially if you plan on getting tuned once. However most all modern cars require a tune for the parts being run at the time. The MCS/JCW running a TBE without a tune is no exception. Does the car run, sure. Is it optimal? No, not really. Running the proper tune for your cars current parts list is almost always advised for the safety of the motor.

If he gets the parts before hand and has the muffler broken in (as materials need time to settle), and then goes up for a dyno tune, Jan will be able to more precisely tune for that exhaust.
thats my .02.
@David-- i get it back this Friday. I've driven a week with the resonator on, and it hasn't gotten any louder after the first day. So its settled in (I drive over 600 miles a week)-- the drone is much much improved from when I originally did it. Honestly, if the amount of noise in the car now bothers one, then one might as well not get an exhaust, as they won't be able to handle the expected increased decibel noise created from an exhaust anyways. Do it. If you're really worried, leave the 2nd cat on, or get a longer resonator (not by much though, mine fit right in the straight part of the front of the exhaust when we welded it in, so maybe one or two more inches of resonator would be ok). You can always go up in diameter too, but I'm not positive how this would effect drone/sound (technically, it would muffle it more, but they are so straight through that its hard to tell).
Get your parts off performancepeddler.com it almost definitely won't be cheaper at an exhaust shop. aluminized steel piping is the cheaper way to go. If you don't see salt, its not a problem. I do, and I have aluminized steel, but I rinse my underbody once a week in the winter anyways (new england), and i don't have problems with it rusting now after 2 winters with it. good luck!

Eddie,
Do what I did! Find a shop with a Dyno that'll host the event and then get together at least 8-10 people who want tunes (check with Jan to see what other cars he's willing to work on while he's there) and make it happen! I was lucky because Dan at Mach V took it and ran with it to coordinate dates with Jan and to take deposits to schedule a spot.
I agree with the posts above though, get your mods out of the way before your tune but there are a couple of mods that Jan can adjust for afterward.
Good luck and enjoy it when you can make it happen!

Jan's been so busy lately, he hasn't even had time to post anything to this thread so I'm guessing the end of the racing season has him scrambling like crazy. I'm willing to bet we'll see more from Jan once he gets a chance to see his family and sleep for 3-4 days straight.
While not directly related to this thread, I did order a downstream 02 sensor standoff with a catlytic grid from bigdaddy's garage. It arrived in the mail yesterday and I'll try to get out and install it this evening if the rain stops... I've got the RR Catted/Coated DP and the CEL (P0420) that goes with it so I'm crossing my fingers that this neat little device will fix it up.
