MikeyM Posted January 1, 2016 Share Posted January 1, 2016 (edited) Hi.. i did do a search but came up without the answers ... My 05 plate Z has a full decat exhaust system, this has caused the engine light to come on. I have been told this can be solved by doing an O2 sensor bypass.... If thats true..is it done via ecu update or is it a physical wire bypass ? Anyone done it, is there a HOW TOO ? Cheers :-) Edited January 1, 2016 by MikeyM Quote Link to comment Share on other sites More sharing options...
Vlad Posted January 1, 2016 Share Posted January 1, 2016 It can be turned off via software. If you planning UpRev remap, it will be turned off then. Quote Link to comment Share on other sites More sharing options...

I am planning on a remapp at some point in the future.. Being quoted £275 for that.. But told have plenum spacer done, decat exhausts and pop charger first to get the best from the remapp.. Apparently he can get me up to 315bhp and he did nention Torque increase but cannot recall figure, which is a shame as Torque is what i look for :') Quote Link to comment Share on other sites More sharing options...

You will get a very small increase with the rev up however driveability will be improved. As been said the rear sensors can be made redundant with the tune.

I just double checked his statement and he is saying "i can achieve 315bhp and i can improve on the stock power of 276bhp and the 350nm torque. zero260 Stage power 315Hp & 389Nm. this is a safe and reliable map but i maybe able to squeeze slighly more from it with the decat and air intake thats been done. again within its safe limit" What do you normally expect from a remap ?

Vlad Posted January 1, 2016 Share Posted January 1, 2016 Usually no more than 300bhp I would say. Only few people got just over 300 from 276. Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted January 1, 2016 Share Posted January 1, 2016 What software is your tuner using ? Can you name your tuner ? Quote Link to comment Share on other sites More sharing options...
MikeyM Posted January 1, 2016 Author Share Posted January 1, 2016 What software is your tuner using ? Can you name your tuner ? No idea on software.. they have said they need to remove the ecu and do the work on a bench and could take up to 6 hours basically. They are called Zero260 https://m.facebook.com/Zero260-Remaps-1638192393123276/ Quote Link to comment Share on other sites More sharing options...
Vlad Posted January 1, 2016 Share Posted January 1, 2016 That sounds a bit dodgy! I would rather go to reputable tuners. TDI North, Abbey Motorsport, Horsham Developments etc! Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted January 1, 2016 Share Posted January 1, 2016 Agreed! bench tuning the ECU although the up rev can be done like this I suspect its not up rev software, especially since the price is cheap, I would lay money he wont get that sort of BHP, and if he is making that sort of claim why no dyno to prove it? As for the cat monitor sensor delete, the best way is to have them turned off via up rev, but you can run without them, you will just get a constant CEL, but as they are not normally used except when there are other problems it wont cause any issues.
