Dblock Posted December 13, 2011 Posted December 13, 2011 Decats made my fuel economy a teeny bit better. Lambda sensor broken? Quote

Looking for suggestions please If your using that much fuel you better check for leaks. Thats about 10 mpg. Quote
Mega Posted December 13, 2011 Posted December 13, 2011 The economy is about what I get anyway. Disconnect the lambda sensor and if economy doesn't change at all then it could be an issue: The car could be running rich. A dyno run would also give some answers. Not the easiest of things to work out without a garage to assist though Quote
Neilp Posted December 13, 2011 Posted December 13, 2011 this is the reason you should always have the car re-tuned after doing major mods. Get the car booked in at abbey motorsport, rs tuning, or horsham for uprev tuning Quote
Dblock Posted December 13, 2011 Posted December 13, 2011 he got it remapped plus if you put decats on you don't magically drop 15mpg be aide of no remap. this is the reason you should always have the car re-tuned after doing major mods. Get the car booked in at abbey motorsport, rs tuning, or horsham for uprev tuning Quote
Bobby81 Posted December 13, 2011 Author Posted December 13, 2011 as above i remapped it after fitting the decat and mark didnt comment on anything unusuall ! i got the decat from horsham and i think they are decent ones .. Quote
Stew Posted December 13, 2011 Posted December 13, 2011 I'd maybe speak with Abbey. Unless you are now ragging the car everywhere it doesn't seem right. Quote
Bobby81 Posted December 13, 2011 Author Posted December 13, 2011 lol, not at all, im driving with D1 throttel cotroller on euc3 , i will give abbey call and try to disconect the lambada sensor ! im a bit worry now Quote

Get the car booked in at abbey motorsport, rs tuning, or horsham for uprev tuning I didn't see any difference in mpg after fitting decats. Are you supposed to run a throttle controller after a remap? Most people seem to get rid of them afterwards. Quote
Chris`I Posted December 14, 2011 Posted December 14, 2011 Speak to Mark and see what he says. He has seen the car first hand, so knows a lot more about it than us. I would suggest disconnecting the throttle controller. It might not be playing nicely with the tuned throttle map and my be causing the car to inadvertantly run rich. Quote
Mark@Abbey m/s Posted December 14, 2011 Posted December 14, 2011 Bobby, PM me your reg number please. Mark Quote
evilscorp Posted December 14, 2011 Posted December 14, 2011 Decats made no difference to my mpg. Sounds like a problem somewhere else, do you have lots of black smoke out the rear? Quote
Mark@Abbey m/s Posted December 14, 2011 Posted December 14, 2011 Bobby ,You left a message on my work phone and you didnt leave a phone number. Mark Quote
Bobby81 Posted December 14, 2011 Author Posted December 14, 2011 No, no black smoke .! I'm going abbey next week to get it check .. Quote
CrumbMC Posted December 14, 2011 Posted December 14, 2011 My grand scheme for after MOT is De-cats then a Remap. Can't find too much info about them on here. What is the best De-cat that is still a fair price? I'm after a bit of volume and raspiness so this wouldn't bother me... ?? sorry Quote
evilscorp Posted December 14, 2011 Posted December 14, 2011 Horsham developments do good priced silenced de-cats which are well made, quality welding Altho they make the car louder it really depends on the rest of your exhaust to give it a raspy noise. My true dual isnt raspy at all. Quote
CrumbMC Posted December 14, 2011 Posted December 14, 2011 I have an Invidia Gemini true dueal which is fairly quiet so i'd be tempted to go for a non-silenced one. i'll have a look into whats available though. I love the sound of this Zed Quote
JT350GT4 Posted December 14, 2011 Posted December 14, 2011 CrumbMC: The sound of that exhaust sounds immense ! Is that just the Nvidia? No other mods like HFC's? Quote
CrumbMC Posted December 14, 2011 Posted December 14, 2011 it has turbo xs test pies and maybe a pop charger Edit: and a gemini ofc Quote
