Hello everyone
Im lucky to own a R56 S with the N14 engine.
Currently im looking to get an ECU Tune
Im running a dp decat full straight pipe, K&N panel filter an Airtec IC , NGK spark plugs. Soon i ll buy the BOV which will probably be a Forge one.
I wanted to ask you about the Tune
What parameters should be taken care of in order for the car to work properly and without problems..?
For example : Should the thermostat temperature be lowered?
What else should i be aware of?

If your putting all that on it. You might want to get one of these to get the big power. I'm actually thinking about putting this back on mine after I get a R 55+ inch catalytic convertor, as to not throw a engine light.

when cat is removed ecu needs remapping and down stream 02 sensor needs writing out of ecu and all fueling trim done be the upstream 02 sensor thats first off, adding power to these engines there is a limit where they will bend conrods ,, 230bhp at crank or around 210bhp at wheels is fairly safe,, will say as with any remap the driving style must change ie cant drive them low high torque revs as much as can bend rods and knock out crank,, needs to be reving over 2k all the time in revy gears to help it,,
must ensure before rolling road time ie best way to have remapped in my book to have clean air filter also have good petrol high octane you can get in your country,, in uk we have shell V power 98ron these engines need high octane fuel best , yes there is a updated thermostat housing runs 105c the oil ones were 112c and to hot,,
if like someone has said if you want big power that comes with big money needs forging, hybrid turbo different coils to take iridium plugs , 280bhp ish is there put gearbox and clutch will hurt for it, also fitting a sport cat with lower amount of metals in it you will still need the cat files removed from ecu as will flag up efficiency eml fault codes after a few miles. also will add if the remap is not done correctly and i have seen people melt them down through fueling them wrong at top of the rev band ,, having someone who knows what they are doing is a must

Thank you mate for all the advice you are correct at everything
Im not going for big power just yet i actually dont even look at the numbers i just want a car that runs correctly without problems and just a bit faster than stock.
Im just curious if any SPECIFIC parameters should be taken care of during the Ecu Tuning. I will definitely tell the Tuner to afjust the thermostat temperatures and to erase any faults from the decat.
