Yes why not. The trans has nothing to do with the engine ecu.

Maybe, but the stock dme is very much involved in shift characteristics.

I don't see the need for a standalone ECU here. What big changes are there? Redline is lower than stock. Solid lifter's and a dry sump? Not making a lot of sense. Also has anyone really had issues with the cooling system in the e92 in stock form at the track? Although its not a dry sump system, it seems quite efficient.

I would prefer to see a flat-plane crank, 4 litre version with head and cam work for this price making 550 whp at 9k rpm and run it off the stock ecu

These guys aren't marketing these builds for some knucklehead that blew his motor. They are for race cars. And with a winning track record second to none in the BMW world.
Haters keep posting.

Me too, but that's asking a lot.

The stock DME is still very limited. An aftermarket ecu is def a must to pull everything from this car. I would bet a motec or pectel on a relatively stock car would still show serious gains. As above was stated, this isn't for eveyone. This is a solid lifter almost race car type piece.

How would an aftermarket ECU extract gains on a stock car? Not a rhetorical question.

This.

I will attempt to answer any questions you guys have on Monday when I am back in the office and can get you legitimate answers. The fact of the matter is I am not nearly qualified enough to answer racing engine questions.

What I can say and this has been reinforced many times over in the office is that the Club Race engines are RACE CAR ENGINES. They are meant for dedicated track cars. By no means are those engines meant for any car ever seeing street usage. If you want a powerful street car engine then the standard Stroker is the top of the line at Dinan NOT the club racing engine.

Lol the tcu and ecu have to be able to "talk" to each other how do you think the dct blips when you down gear

I don't think you understand how advanced these aftermarket ecu are.

Dinan, what if anything did you guys do for main, rod, and crank bearings? Are you using special coated bearings, or running oem?

It would be minimal and most importantly not really cost effective. For a car with lots of bolt ons and cams, etc. you would prob see some gains but again the cost of entry is kind of prohibitive to those types of people.

any dynojet pulls yet? 40k for an engine that can buy you a faster c6 z06 instead needs to be proven

This has been asked a few times. I am curious what the answer is. My understanding is that Dinan machines the crank to allow for proper bearing clearance. But, that is just a rumor.

I would so do this if money was no object. having a S65 N/A well over 500HP is epic.

Unless you're a club racer, the money would likely be better put to a CPO GT3.

but when money is no object, i would already have a GT3.

these are the types of people who would buy this.

I don't know why so many people are surprised by the price. Yes the motor is expensive no doubt but They are priced very fair.

Whether people think it is worth it or not in their street car ( for which it is not intended) or in their imaginary racecar is a different discussion.

The e9x platform has matured and we will begin to start seeing a lot more awesome e9x track cars and dinan making these types of parts and continuing to focus on stuff for the e9x is only a good thing.

I'd rather have a s85 swap. V10 noise in an m3 sedan/coupe would be perfect

It's done !

Contradicting yourself as usual I see. Just above you stated that a stand alone on a relatively stock car would show serious gains.

On a separate note, the price is relatively good considering people are paying $20k+ to rebuild their factory engines for low compression supercharged build projects. Given the additional performance, parts, experience and reputation of the builder, I think it's on par for this platform.
