Juan......
Dan that's what I get for trying to be civil. At some point back then I figured just drop the animosity and get along. I was trying to rationalize my experience and efforts. When go back and think how Dinan treated me and the guys working on my car I get angry all over again.
Add to that, being told by people who know BMW (Steve Dinan is not the only one) that I wasted my money does sting. Hell money comes and goes, big deal but the worst was Dinan's behavior. Mind you the conversations were all proper and no profanity ever used.
Heck man, asking for an addition core charge for the 2nd set of TB's sent to try and resolve the poor functioning of the car! That's kicking the man when he's down.
During the conversations about the issues, NOT once did they(Dinan) say well it's your ECU that's the problem. That topic came out later in the TB discussion.
Funny all other cars can run with multiple different components. I guess Dinan has purposely made their products to only work with each other.
I want someone to explain to me what is it that's in the Dinan software that knows exactly that the TB's in the car are Dinan or not? That's psychic software.
I hope M5junky makes new rwhp but gentlemen I am tired of this topic. Dinan goes one way and I go the other and the world keeps turning.
Thank you
1) You're entitled to your Dinan CS opinions. You aren't the first, nor will you be the last, to complain. FWIW, and IMO, it's a function of their business model. They are highly reliant on their North American "authorized" dealer network to provide product sales/installation/service/tech support to their customers. IMO, those dealers are where the "rubber meets the road"; and that reality is why, during almost 16 years of being a user of Dinan products on various BMW's, I've never dealt with Dinan directly (other than a single "curiosity" visit to their Morgan Hill facility, over 1 year ago). ALL of my car related business is handled by their local (to me) dealer, who is also a dealer for many other vendors of BMW (and other German car marque) mods, and who renders outstanding knowledge/experience/expertise/service. 'Would never allow ANY other shop to touch ANY of my cars. Period.
2) IMO, RWHP measurement on a dyno is nothing more than the difference between engine output and drivetrain loss; with highly variable results, and therefore unreliable data, from one "test" to another, being produced. Anybody who actually wants to know exactly what power their engine is producing has to have it tested, out of the car, on an engine dyno. These are extremely sophisticated, very expensive, custom designed instruments; typically only used by engine builders for high level racing application. A street car owner would have to pay a lot of $$$ (and find a willing engine builder who's properly equipped) to get a consistently valid engine power test result; which is decidedly impractical. If you question this, then ask your good folks at Champion Motor Sports.
3) BMW ECU tuning: After many years of threads and posts on this Board, 2 things seem obvious to me. a) Dinan software is developed to work with Dinan mods, exclusively; b) a mix of power mods from different vendors (including Dinan, or not), requires a "custom" tune; which vendors such as D/A, Powerchip, AA, and apparently ASR, make a business of doing. In another thread, back when you were considering "dumping" your M5. you may recall I suggested you seek a custom tune ('mentioned AA, IIRC); which might get all your different mods working correctly. Your response to my post was "That's the most helpful and logical suggestion I've received in this thread". Well, you took it several steps further; engaging ASR for a custom exhaust, "bottle" mod, AND a custom tune to tie everything together. Now you're happy. That's good.
4) As for TB's (Dinan's or anybody elses), 'think your summary in post #108 (referenced in the thread 'referred to last night) is "spot on" and fairly expresses reality about all power mods, in general.
