Stage 1 MRC remap, any other sensible mods to do?

[Anth]

Arse, I'll give you that one, not bad. I am wavering ever so slightly on the lowering actually after reading Mike's car thread fully. I REALLY want the PE wheels, I think they look lush.

My problem with the PE Wheels are there now common , in our local Audi there on all the SQ5s & 7s not seen a 8 yet . I'm looking forward to seeing what the C8 wheels look like . Saying that drops and aftermarket wheels can look odd for me, I loved the orriginal 21 C7 wheels so put them on from new and sold the PE Wheels . Air intake upgrades are my next call , mikes carbon intake is insane ! Have you seen the meth injection system? I'll get a vid up so not to hijack .

[Mr Footlong]

Meth has never done it for me, I can get my head around adding fuel to go forward and washer fluid to see where I am going, but have an aversion to an additional tank to fill to help me going forward. I am really tempted by the Eventuri system too, but I think that will be on the next phase of modding, will quite possibly do that at the same time as sports cats, should I feel she needs it. With how much this car cost (£43k), and me wanting to try to keep a decent amount of reliability as the wife & babymobile, I am "trying" to be a little sensible.

I never really pay any attention to SQ5/7s around here, so hadn't noticed the wheels, thanks for letting me know though. With that said, I still want them, but I might have to go full custom then methinks...

Decided not to go with active controlling for now. The seller of the CETE valve module on here wanted comical money for an out-of-warranty electronic gadget IMO and got the arse with me it seems when I agreed to offer asking price for the spacers and wheel bolts. I tried being polite, was just told I am wrong blah blah, rubbed me the wrong way, moving on....

Looked into the Milltek controller one, where it states that you press the ESP button twice to control it. I tried pressing the esp button twice quickly on mine yesterday (as a test, the controller isn't there of course!) and it actually disabled the ESP. I could have sworn that is a hold button down for a second or so job, not a double tap???

[MikeFish]

The Milltek one is exactly the same as the CETE one, just been rebranded for the UK Market.
I'm currently looking at the ASR components RX1 controller. As far as I can tell the CETE / Milltek option will still make a nosiy cold start if you turned the car off with it in noisy mode. The ASR one can be set to always start in quiet mode or noisy mode or remember the last selected mode.

[MikeFish]

300 euros (about £266) brand new with 1 remote.

[Mr Footlong]

Hmm, good find Mike - https://asr-component.de/home/40-klappe ... d_standard

I do like the idea of it being totally external to system BUS (not a lover of the remote fob, but a necessary evil with this type really), but then again I will have to get my head under the back and see where the box O' tricks/cabling can tidily be installed and will be as immune as poss to water ingress and driving at speed.

[MikeFish]

I think all types plug into the exhaust. The can bus bit is only used to get the info from the esp button to the unit, but then the unit plugs into the valves. Sounds to me like both types of unit will live inside the car and just a wire run out the boot to the valves. I could be wrong though.
I'd also like a switch in the car so I'm not fumbling around for a key fob whilst driving but if you look at the ASR option for the RS3 you can buy it will a new OEM switch to install on the dash. I was thinking about buying this version then wiring to a switch on my dash for changing modes whilst driving easily.

[DaytonaMatt]

I ordered the CETE but while I was waiting I unplugged my valves. The wife didnt noticed so it’s not too obnoxious.

TRhis is on a sports exhaust rather than anything fruity thiugh. No drone at all (which I did get on my M4 with Remus catback and valves all open)

[Mr Footlong]

Mike, while it is tempting, I have a nasty feeling that I will buy it, crack the box open, only to find that I have no way of soldering/plugging in a remote switch. Saying that, I would be surprised if the PCB/coding on their device didn't still have the remote cable ability in it..

Which one of us is going to be first to pull the trigger though? I reckon I will take a punt next month.

[MikeFish]

Looks like the switch attachment is a simple 2 wire jobbie. Could be wrong but any switch on the end will work. I think I'll have all the parts for a cat back by this weekend. Then I'll know if I need it or not.

[Mr Footlong]

Getting one as a Chrimbo pressie now.

I am failing to resist the urge to swap out the OE cats with the 100 cell Milltek jobs. Brutus has had them on for seven years now and she flies through every single MOT on emissions. I can't help but feel that I should be completing the non-res job on this by adding them too at the same time as the remap.

Yes, it is 2k that I don't really want to spend right now, taking this remapping much closer to the £5k mark, but bloody OCD and is there much benefit to me doing this or am I really expecting diminishing returns adding this on?

Purely when compared to the OE design, the far more direct flow seems pretty obvious. I absolutely won't run decatted, done it once, never again, not worth the hassle for me at least.

Thanks for any input on this.

The bit everyone misses because its too difficult. Can release big gains, around 40bhp I believe

[dhali]

WoW . Impressive bit of fabrication there

[Mr Footlong]

Ok, MRC have done their usual magic and I pick her up in the morning. Switchable mapping apparently, no bloody idea how that is going to work, but sounds like a good idea tbh as I was a bit worried about the additional strain on the car when I have a lead foot for the most part.

Final config for the car was -

Beissbarth 4-wheel alignment to hopefully dial out the full throttle torque steer/squirrelling that my other aligner couldn't
Milltek Full non-resonated exhaust system with 100 cell cats
Autotech uprated high-pressure fuel pumps
NGK 4905 race plugs
Uprated air filters
MRC Stage 2 Remap on Tesco 99 with switchable mapping.

Results below ladies, not too shabby!!!!!!

[Daveperc]

Great stuff!!

And how was the drive home

[MikeFish]

Great stuff!!

And how was the drive home

He picks its up tomorrow he said. Pay attention Perc.

745 is a great result whilst still being MOT compliant. Congrats.

The timing of the runs is odd though. The clock says the highest power run was 1st run then the 2nd highest was the 2nd run and lowest power was last run.
