Hi can any one give me your experience on ECU tuning on W213 E63S with one of the following companies, DMS, Pure Tuning, JF Automotive, AMF Automotive, AMD Tuning, GAD Tuning or the True Tune hand held ECU Tuner. I am in Margate so don’t fancy a 7 or 8 hour round trip to MSL. I would appreciate your feed back on any experiences you have had with any of these tuning companies or the true tune device.

Mike, 585 bhp not enough :oops:
If it isn't then GAD are very well thought on here, as are MSL, with that kind of motor, you really want someone that knows what they are doing. I appreciate it's a bit of a trek, but it would be well worth it, and what a drive home! 🙂

Thanks SmartAmg 612bhp is okay but can always do with some more 😊 yah MSL is around 7 to 8 hours round trip plus couple of hours tuning so long day and long drive, GAD is only 4 hours 20 min round trip so better for me but hear great things about MSL just concerned about having to do that trip if i have any problems with the map and have to get it shorted.

Fair enough, Mike, I can understand your concerns, although never heard of any problems with there maps at all. GAD are also very well respected, they post some great videos, on t'other side, 😉 check um out. 🙂👍
 
Mike, check out the W213 E63S remap thread, in the AMG lounge. 🙂👍

Simple terms yes immediate fail, think you'll be OK removing the centre cats and/or centre resonator if you wanted a little more noise. you'll need sports cats to pass the mot and keep it Road legal. Pretty sure and keep in mind if your car has an invalid mot it can void your insurance as it should not be on the road. If someone was go hit you, and their insurance company do some digging you'll be left out of pocket.

Hi Stevie this is what i thought but was surprised how many E63 owners have decated there cars and just wondered how they are getting round the MOT and insurance issues? I would only be putting sports cats on to get better breathing of engine, and don’t know if my car is fitted with the OPF as reg late Dec 2018 but know end build date was 1/10/2018 so might or might not???
I am going to have jake it up and have a look under to see, you mentioned centre cats ? why does it have two lots of cats ! I know from photos there are cats at the top of down pipes and there is another unit at the bottom end of the down pipe is this the OPF or is this another cat unit which is the joint to exchaust system and the one they cut off to removed down pipe if not dropping gear box.
 
Most cars will easily pass the emissions tests with just the secondary cats missing....which is how many MOT centres do the test.....but technically it should still fail whether it passes the emissions or not.....as it's now an instant fail to have any factory fitted emissions equipment removed or obviously modified....so that's cats, dpf, egrs etc.
Of course it's also illegal to drive on the road with these parts missing or modified.....£1000 fine....£2000 if a commercial vehicle.....like a van.
That said I've never heard of anyone being fined or any insurance claim not being paid out either.
Funny thing is that although is illegal many insurance companies will cover decats etc for an additional premium....very odd.

Thanks ALFAitalia for clearing this up for me I a bit confused with all the posts and youtube clips of E63S being decatted by MSL GAD DMS and the likes just wondered how they got away with them missing on MOT and emission test.😊

A friendly MOT tester won't care. Sports cats will still likely pass emmisions, or if keeping the main cat and removing the secondary cat again will likely pass the test.
 
It's not an mot failure if you remove one set of cats but leave the other intact, as long as it passes the emission test. To my understanding its the emission bit that matters.

Had a mx5 tested at mazda and was clearly missing the downpipe cat, only thing on the exhaust that was stock was the main cat, I left it just to pass the emissions. Which it did

Its an mot fail if any original part of the emissions control system has been removed, regardless or whether it passes the emissions test.

However it's down to the tester to know and enforce, and many won't know the cars in enough detail to know if something has been removed.

I was under the impression that they weren't allowed to use the specific knowledge of a car when testing?
 

If there is obviously a straight pipe where a catalytic converter used to be, that's enough. They aren't taking off engine components or diving into software to check.

So as a Merecedes benz spicalist would say that with sports cats fitted replacing the orginal primary and secondary cats it will pass the MOT emission test! Have you had any experience with E63 that have had the original cats replaced with sports cats on the side of MOT testing or do you not carry out MOT testing?
 
We don't do MOTs.

However, if the the tester doesnt know that the cats are missing, it will pass based on the emissions.
If the tester does know the cats are msising, it (should) fail as mentioned, even if it emissions are within spec.
 
Both my E55 and E63 had the cats/resonator removed and went through the MOT test numerous times without problems.
That's not to say it's a definite pass or fail, just dependant on the tester. I'm sure there are thousands who only look at the emissions and condition of the system, not for what is missing.
