Seriously bad fuel economy

[Ibiza Cupra]

Thats why you brought a diesel!!!!!

But to have a 1.8 20VT producing over 250bhp Fuel economy can't exactly be no1 priority!!!!

If he was that bothered he should of brought a diesel!!!!

The car was fine when mapped, it slowly got worse, in my opinion, going by previous 1.8T cars I have owned, remaps do make them MORE economical if you drive sensibly, it's only when you're on full boost that the fuelling is seriously increased, Mike at Jabba confirmed that fuelling for pretty much anything under 10 - 12 PSI of boost (standard boost pressure) is untouched so really I shouldn't be getting a bad economy hit. Remap's do NOT mean that cars drink lots more fuel, only if you drive with a lead foot. Its simple, an engine makes more power by getting air through the engine faster, the increase in more air also needs more fuel mixed with it to keep safe A/F ratio's, so what im trying to say is, if you use all 280BHP of a remapped car then yeah it's gonna drink like a fish but if you drive sensibly then fuelling should be no worse than the base map. Hope that makes sense

Oh ok, sorry i have misunderstood something!!!!

There is poor economy and then there is crazy rubbish poor the petrol into the drain.....

Ooooo have you got a petrol leak?

 

[Balf2k]

There are definitely no leaks

How long have you had the remap????

Any other mods?? Indution kit?? Exhaust????

 

[Balf2k]

had the map a month, mods are turbo back Blue Flame full system with 100cell Cat, Evoshield inlet manifold spacer, Forge 007P diverter valve, Forge TIP, Jabba adjustable boost controller with Remap (I notice zero difference in consumption if I have the boost controller on minimum or maximum). Can someone tell me how to check my Lambda's with Vag-com?

 

[m0rk]

I can't remember which measuring block it is.... but they're labelled up

 

[Balf2k]

I have a really old version of Vag-com cos I have an unofficial serial lead so it doesn't tell me what sensor is what,
like the newer versions do? Also, even if I got the right measuring blocks, what do I look for, what sort of figure etc?
