Everything with the evo felt like mitsu intended people to race them - from the ease of getting negative camber in the suspension, to the brakes, to the seats, to the ease of stripping the interior. It made for fun modifying experiences! BMW is just a bit different...

Completely agree. Had an Evo as well that was modded and tracked. Much more easy and cheap to mod. When giving that up and purchasing this car I decided I will be keeping my f30 (328i) as stock as possible. My only mods might be msport grills lol.

Stage 2 - $1,799 (oil cooler required)

Stage 3 - $2,199 (oil cooler required)

Not cheap by any means... However, it will be a reflash (rather than piggy-back) and Dinan backs theirs by matching BMW's factory warranty (4yr/50,000 miles).

When and how much we shall expect on 328i?

I had decided to try to keep my 328i as close to stock as possible as well. (My previous car was a 07 GTI with Borla exhaust and APR Stage 1.) But I'm slipping I just order the BMS Tune yesterday and have been looking at the exhaust threads. I see that Borla is coming out with a 328i exhaust which has me very interested.

Here is an very interesting and detailed chart comparing the various tunes offered for the e90 335 N54: http://www.e90post.com/forums/showthread.php?t=374508

I suspect many of these companies will eventually offer a tune for F30.

You guys who have the BMS tune, you have been disconnecting the battery first, right?

Thanks!

I figure the battery is closer to the rear bumper and in front of the little storage tub. Never had to locate it before hehe.

General bmw owners aren't real "track" savy u know.. i bet half the people in here will be real happy if they get custom dyno tune at $6~700.

$150 for a “custom tune” sounds a little too good to be true! Dyno tuned? Data-logging and having the car remotely tuned? Was there any hardware required?

Eh, I really wouldn't call a sub-$400 piggy-back that yields appx. +40whp over-charging. I'd actually go so far as to say it's an excellent deal.

The BMW-tax does hit hard in some areas though, such as authentic Euro or JDM aero & exhausts. If you compare material cost to retail cost it's clear they're selling their name, and people still love to pay for it.

Dude wtf.

My N20 is not the same as pictured in the install pics from BMS.

I swear based on the pic I took, I actually remember seeing on the N26. I thought manuals were N20, autos and certain markets were N26. Maybe mine is later production(7/12) and they switched over to the N26?

Here are my pics:


In the install manual, the first sensor I need to tap is right next to the oil cap.

Well here is mine, no sensor next to the cap:


I have this feeling I have an N26 lol.

edit: Terry confirmed-It's an N26...Or, it's an N20 and they have switched to using the electric solenoid from the N26.

Yes, I read about this. For MY2013, electric solenoid in the N20. I understand you just leave the JB1 solenoid connector disconnected.

Looking forward to your review of the JB1.

My review is a bit stunted.

I am on 235 width snow tires. The car makes enough power where the traction control is intervening quite often.

The power is noticeable. Most so in lower gears and part throttle, less so at wot in 6th.

It is not as drastic as my APR tune for my CC but that went from like 12psi to 18 and cost $600 on sale.

For $300 the results are quite good. If I was to spend $1000+ on a true tune and not a piggy back, I would have higher expectations.

I can say it pulls equal to the 335 I had for a week. When I get my production exhaust put on, results should be even better.

I also wonder how equipped the stock intercooler is at combatting heat soak.
