hughes21 Posted April 23, 2013 Share Posted April 23, 2013 Getting an emb Friday and will get it mapped as soon as I can but will my car be better on fuel noticeably ?? It's at 0.9 on td04 an its really bad on fuel the fpr is set at 3.4 bar and I barely get 250kms to £30 is that normal or not ?? Quote Link to post Share on other sites
LeeG Posted April 23, 2013 Share Posted April 23, 2013 That doesn't sound that bad tbh as you will be only getting like 22 litres for £30 Quote Link to post Share on other sites
hughes21 Posted April 23, 2013 Author Share Posted April 23, 2013 (edited) It's working out about 20mpg cruising offBoost I put fuel in all the time no matter what and I no it's going to be bad on fuel but didn't think it would be like this hopefully when mapped itl be better Edited April 23, 2013 by hughes21 Quote Link to post Share on other sites
AdamB Posted April 23, 2013 Share Posted April 23, 2013 Your fuel pressure is way too high for that boost pressure. Thats your problem. Quote Link to post Share on other sites
jellybaby Posted April 24, 2013 Share Posted April 24, 2013 Also as said above ya just get less fuel for ya money these days due to stupidly high prices Quote Link to post Share on other sites
hughes21 Posted April 24, 2013 Author Share Posted April 24, 2013 Your fuel pressure is way too high for that boost pressure. Thats your problem.I just checked it earlier on idleIt's about 3.8 bar which is mad high but I've only just had it health checked on the dyno - getting an emb soon reckon I should tone it down to about 3bar or just wait for a map but I use it daily and could do with it being a bit better on fuel haha ;) Quote Link to post Share on other sites
Jim* Posted April 24, 2013 Share Posted April 24, 2013 I'd wait, don't turn it down unless it's on the dyno and they can check, you don't want to run lean as it will always end in tears! Quote Link to post Share on other sites
hughes21 Posted April 24, 2013 Author Share Posted April 24, 2013 Yeah I thought that gauge could be out you never no - just car stinks of fuel aswell but I have No leaks and when I boost it smells so fuelly Quote Link to post Share on other sites
Jim* Posted April 24, 2013 Share Posted April 24, 2013 just wait until it's mapped bud, it's a small price to pay over your engine blowing up.... trust me haha Quote Link to post Share on other sites
Weyro Posted April 24, 2013 Share Posted April 24, 2013 thats about 32mpg isnt it? Quote Link to post Share on other sites
hughes21 Posted April 24, 2013 Author Share Posted April 24, 2013 thats about 32mpg isnt it?It's a bit less than that I worked out I know its never going to be great anyway paying £1.47 a litre here haha it just stinks of fuelWhen you rev it just made me think its burning it too much and running very rich Quote Link to post Share on other sites
Weyro Posted April 24, 2013 Share Posted April 24, 2013 when i was using a rrFPR on my td04 at 1bar i had the pressure at 44psi, and it fueled at an afr of 11.4 which is pretty ideal for that setup Quote Link to post Share on other sites
hughes21 Posted April 24, 2013 Author Share Posted April 24, 2013 when i was using a rrFPR on my td04 at 1bar i had the pressure at 44psi, and it fueled at an afr of 11.4 which is pretty ideal for that setupWhat bar was 44psi ?? I looked at my dyno graph and compared it to my brothers when he was at a bar and its complete different fuel wise think i might just wait and get it mapped on the emb or turn it down to about 3.1 and stay off boost for safety Quote Link to post Share on other sites
Weyro Posted April 24, 2013 Share Posted April 24, 2013 44psi is about 3bar, if i was you i would just leave it alone till you get it mapped, for the sake of a few extra mpg you might melt something Quote Link to post Share on other sites
TurboTobz Posted April 24, 2013 Share Posted April 24, 2013 Safe option is run under fuel cut and run 2.4bar or standard fpr, the map sensor should correct the fuelling itself then. If you don't want to mess about with your fpr settings put the standard back on until emb time joe Quote Link to post Share on other sites

If you don't want to mess about with your fpr settings put the standard back on until emb time joe x2 this man, your fuel pressure is way too high at 3.4-2.8 bar. Thats just on idle before it even starts seeing boost. If you go over 4 bar of fuel pressure it starts to become harder for the ecu to control the injectors, even some standalones struggle with this let alone a stock ecu!

hughes21 Posted April 25, 2013 Author Share Posted April 25, 2013 I've just tinted it down to 3 bar and I'm going. To stay off boost buying en emange tomorrow and will hopefully get it mapped next weekend Quote Link to post Share on other sites
