Patrico777 Posted January 21, 2016 Share Posted January 21, 2016 I want to ask why are these fiestas tdci s at 70-80mph in high revs like more than 2500rpm Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted January 21, 2016 Share Posted January 21, 2016 The 1.25 & 1.4 duratec is at 2.5k at 70mph too.. Although, at 70 the car just wants to pull and pull, and despite the high revs once you start giving it some, barely drinks any fuel ;) www.yorkshiredetailing.co.uk - approved resellers of the Highest quality detailing & Valeting supplies Quote Link to comment Share on other sites More sharing options...
Patrico777 Posted January 21, 2016 Author Share Posted January 21, 2016 Yeah it pulls but that high revs its 1.6 I do not get that Quote Link to comment Share on other sites More sharing options...
Patrico777 Posted January 21, 2016 Author Share Posted January 21, 2016 On a separate note... I use my fiesta mainly on m'ways and found it shocking that a diesel engine is made to run constantly at 3000rpm if you intend to do 70 -75 mph. Is a remap/tuning box going to change anything? It seems a bit pointless having a diesel which is over-revved at motorway speeds. Even a 1.6 golf tdi keeps it under 2000 rpm at similar speeds. This was said by one guy on this forum TRUE what he says Quote Link to comment Share on other sites More sharing options...
GingerFlame Posted January 22, 2016 Share Posted January 22, 2016 A remap won't change the gear ratios.. I'm afraid it is what it is. Also, 9/10 "tuning boxes" do absolutely nothing. Spider tuning apparently work but again.. it's the gearbox you don't like www.yorkshiredetailing.co.uk - approved resellers of the Highest quality detailing & Valeting supplies Quote Link to comment Share on other sites More sharing options...
m1tch Posted January 22, 2016 Share Posted January 22, 2016 The TDCi fiesta is geared for around town really, you would have to swap the box out for something else or find a 6 speed box if available, even though the engine revs fine, its only if you are doing illegal speeds it would rev up higher. I used mine for the motorway commute every day, its fine, its designed to rev at that RPM, it also means that you are in the powerband when needing to overtake from 60 to 70 anyway. 1 Quote Link to comment Share on other sites More sharing options...

frund Posted January 22, 2016 Share Posted January 22, 2016 The later 1.5 tdci have a high ratio box. Great when you are out of town but seems too high geared most of the time not a patch on the 1.6tdci 2008. Quote Link to comment Share on other sites More sharing options...
