Supersprint Decat Straight Pipes
« on: May 21, 2015, 10:36:45 pm »
Guys, i fitted my Supersprint full exhaust system (Decat no silencers). Firstly its crazy loud, need to get a back box before I get pulled over by the police. But what an amazing sound she makes, will get a video up for you guys to check out.

My problem is the car seems to run rough since fitting the exhaust. The air/fuel mixture seems to be off. On idle it sounds like an old v8 banging away. Driving seems fine in low RPM's but when i give her the beans there is not much happening and even a slight hesitation on pick up.
She is drinking petrol, and popping and backfiring more than anticipated?

I have the original lambda sensors fitted to the turbo down pipe, could this cause the problem? no warning light yet.
I also have a TMC tuning box, with an exhaust mod the box should adjust to the new performance gains and 'self learn' is that correct? do i need to reset my ECU? or do I need a full Re-Map?

Anyone runa Decat pipe and had any of these issues? HELP :(

    Reset my ECU today, and had the TMC box on setting 6 (TMC factory setting) seems to have drastically improved the cars performance and fuelling issue.
    I believe running the TMC box on 7 or 8 should support the mods (Decat & BMC filter) much better. (Setting 9 might cause 'limp mode' i have been told)

    If anyone has a TMC box and Decat, please let me know any past experiences you might have encountered.
    Time to get a Backbox installed and dampen the beastly exhaust tone!! Resonates under acceleration, will burst ear drums if I go on a long drive :(
