Cool rennteh evm problem

Hi my s63 came with a renntech evm but didn't have the remote from renntech so I bought one fast forward I tried to pair the remote to the motherbord to get the remote to open the valves but my motherbord seems to not work thare is no light that pops up on mother bord. So i tried lifted the car and checked the cables everything seems good but dont know what my problem is. Has anyone ever had this problem and can a mother bord be fixed because renntech wants $500 for a new mother bord too much! Also dose it relly make a diffrence in the sound.

No experience with the EVM, but as for the sound, sport mode opens the exhaust valves. That would be the sound. You could have it coded to start in sport mode (keeping valves open at all times) and wouldnt need the evm.

I guess stock doesn't open fully so it does make a difference, it opens full at high rpms but once at low rpms, even sport will close it up quite a bit. OP could consider importing a new ASR one using mail forwarding services if that is cheaper. ASR is who made these. RENNTech just was in charge of rebranding and then selling it in USA.
