Remap Advice please!
Discussion
Thought I'd post here to ask for some independant advice!
I've had my E60 M5 remapped twice now, once it was a disaster, won't mention deatials. 2nd time was completed by DMS, VERY happy with the service and results.
I will be popping into DMS this week to ask the same question but I thought I'd ask here out of interest to see what other independant people thought.
This week I'm driving down to Italy to get a full exhaust system fitted, headers and full system. They do not know yet whether it will be full decat or race cats. They will keep the car for between 1-2 weeks and get the most power possible out of it. I Have to put the car BACK to standard before taking it there. So remove RPI ram scoops and Evosport Pulleys.
My question is should it need a full remap from having the headers and exhaust replaced to gain maximum performance? SO should I re bolt on all the mods, ie ram scoops and pulleys THEN get it fully remapped? Will the current remap be adequete or will I see more gains if they start from scratch. The car WILL have CEL due to it reading incorrect emissions so it will need some software.
I am unsure about how the whole remap process works. So do people like DMS just have 1 set of software they load or can they play around with it with all the extras to find the best performance gains?
Thanks for any advice in advance!

I wonder who 'they' are?!
Are you having an exhaust made up by TUBI? - the only way I thought of that name is that you said you're off to Italy. Another person I know has an E60 M5 and has recently put on his TUBI exhaust onto it. Or is it some other manufacturer?!
I'm also thinking that you don't have to take off the pulleys and the Scoops to get the exhaust fitted?
The re-map you've had done will 'cope' with the new exhaust being bolted on, however to ensure it's best potential, yes, I think it's best to get the re-map done again to take into account the freer flowing exhaust system.
Speak to DMS, they'll probably say no need to take off current mods, get the exhaust fitted, pop back to them and they'll tweak the settings for a nominal fee to ensure it's all working smoothly and as best as possible.
Cheers, Dennis!

The only reason the Mods have to come off is because SUPERSRINT want to demonstrate before and after dyno results. The real gains are from the headers not the rest of the exhaust like TUBI. They have been making left hand drive headers with some serious BHO increases for years now, but never done right hand drive. So we have agreed a more "sensible" price than the 12k for the left hand drive system but they want to advertise the gains, clearly can;t do that with existing mods. So fair enough to swap back.

They want to show the gains AFTER the system is fitted so I have to take it down standard, annoying but worth it I think! By the time the mods are back on it should be around 580-600bhp.
So guess it will be back to DMS for remapping, still curious about how the remap works, i.e. is it just a fixed softaware update, I can;t imagine this working with extensive mods, or do they "play around" with it to get maximum gains?
Hi M5Mark,
Ahh ok, now if yer'd mentioned that in your original post! but not to worry about that now.. I see where you're going!
It's good practice to do the new exhaust on what will be a 'standard' M5, before and after testing and a good benchmark is acheived. However, more 'accuracy' would be if the car was new and as close to it's quoted 507 bhp as possible. I know that some 'M' cars produce more and less than others, and then of course if your's was a 'lower' actual output M5 then the results would be 'skewed' slightly. Also, as these engines age, some continue to produce their power and some 'increase' slightly as they 'run in' !
Get your car back to standard, do the Supersprint headers as you say and get all the testing and figures done etc.
Back in the UK, put your mods back on, and yep back to DMS to re-map it all.
A proper 're-map' isn't just uploading a pre determined update. It's taking readings that are being used live by the car, analysing them, and then tweaking them. This of course all has to be done within boundary limits and taking into account all the other elements in a road car engine. This is why professional companies and those with alot of experience can do this kind of work, and not the usual 'lower end' of the scale 'we can do re-mapping too' places. Taking all those vaiables, parameters, customers wants and needs, and knowing what to tweak is a skill. I'd hazard a bet that DMS or any other high quality re-mapping place will say to you, we'll try this and that which we know will be 'good' however lets try this or that and see how things go, and part of that may mean that you drive the car like that to see how it feels and to then report back your findings etc so that they can re-tweak
The 'upload' a standard map type of 'tuning' still exists, but is distinctly the most 'basic' way of re-mapping and doesn't take into account many parameters, and often just over fuelling to make it 'feel like theres lots more power'
Good luck with your headers and resulting power gain, I think it'd be great if you approched the 3 BMW magazine specialists to see if you're car could be used for a writeup and feedback thing for dealers as well as other owners to know about in the future.
I'll buy an E61 touring M5 in a few years time when they're like £15K and hopefully be able to add some bits and pieces for 550-570bhp
Cheers, Dennis!

Thanks so much Deniis thats the answer I was looking for! Pretty much what Mike at DMS said today, Rob is a master with the remap and did his own M5. Which strangely ran at 181 at VMAX where I managed 184 so very pleased with that!
My only problem will be the ever present CEL light from the primary cat delete, Mike at DMS said he can;t remove that so I will have to live it! I guess worth it for the texra BHP and Torque IF there is any gains! I will let everyone know!
