Don't be sensitive, it all worked out well - probably due to the way you spoke to him.
I did provide you with plenty of hints and places to go research further - if you go the Cobb route you're in control, you can uninstall, plus sell it at a later date for what you paid for it - something you can't do with a normal flash (uninstall/reinstall/no value back).
Glad it's back and running!
... but at least the main issue has now gone away !stuartinzg

That is why Cobb/JB4/MHD provide you with various off the shelf maps, you can set it to the condition you are in. They support 95/98+ron, whether you have an upgraded downpipe, intercooler, etc - you just pick according to your needs. It ECU will still compensate for the air density and ambient temperature like it would before the flash. They aren't very aggressive by default, but if you contact BMS or Ken@Wedge they can provide a custom tune which you install remotely specific for your set up ($200 from Ken). When you have crap fuel or a service, just stick the map back to stock - after the initial flash of 30 minutes you can flash after that in 2 minutes. JB4 has on the fly map changing - you don't turn off the car (as it's a piggyback system)
By the seaside...

Remaps, like standard maps have all sorts of correction values programmed in for differences in air pressure, air temp and water temp to name but a few. These are usually fairly standard settings across all different types of vehicles etc. Usually remapping involves playing with the settings for ignition timing, fueling and boost etc and leaving most of the corrections as per the standard setting.
I'm by no means an expert on this stuff but have fitted a good few throttle body kits and aftermarket ECU's to run them. These ECU's give you unrestricted access to the settings in the same way a decent re-mapper would have access to in the OEM stuff. Played around with these settings/maps etc enough over the years to get a decent understanding of how maps work etc.
I wouldn't let using the car in different climatic conditions put me off having a remap, as the correction values would work in exactly way. So you would only see the same relative loss of power you would with the standard map in higher elevations. Fuel quality is a much more critical element.
techathy is completely correct about the JB4.
It works well as a meth controller and and has some nice little gimmicks like shift lights and gauge hijacking but as a boost controller it's just not needed. It's an absolute train wreck on a car with a DCT transmission. The developer seems like a really nice guy who is doing his best to keep his product relevant but piggybacks are only ever a fudge for when you have no ECU access.
stuartinzg is also correct about MHD.
MHD is by far the best option for anyone wanting to tune their car and with a custom tune from Wedge Performance you get to specify exactly what you want from the map.
I know some people like to believe that these remap garages are run by tuning professionals but the sad truth is that these garage based tuners are to car ECU tuning what staff in PC World are to IT experts.
I know his comment may have come across as an "I told you so" but I can see his point. There's an entire forum devoted to ECU tuning on E90Post which is extremely active and 99% of people there either have COBB, MHD or a JB4. There's a good reason nobody bothers visiting a garage to get a remap anymore.
But it's good to see you have the car on the road again without the financial pain of getting a replacement ECU

Sorry to hear about your issues maniac, I get the distinct impression from the J.E . Episode and your story, that this engine customizing /car tuning/ remapping business is a total minefield ,I know nothing about modern car electrics, but the risk to your pride and joy being ruined is such that I wouldn't bother . These companies seem to just lie ,suck you in ,say they can do the job ,nonchalantly screw it up hand you your keys back with a shrug of the shoulders . Are any of you guys still contemplating this course of action , if yes then I think you are bonkers ,bit of a strong statement I know. As a layman I know these cars electrics are ridiculously complicated ,And yet look at some of these back street outfits who claim huge results ,and I think , your a cowboy mate ,hi ho silver away with his money.
