mark-tozer Posted June 12, 2011 Share Posted June 12, 2011 basically im going to be getting a fuel cut defender soon so i can run at 1 bar of boost do i need a air and fuel regulator such as apexi safc or are they for more 200bhp plus. cheers Quote Link to post Share on other sites
Glanza_cl Posted June 12, 2011 Share Posted June 12, 2011 you will need a RRFPR (rising rate fuel pressure regulator) at a minimum. An Apexi SAFC would help tune better fuelling but is upto you.Have a quick read of this and you will be sorted mate :http://www.ukstarletclub.com/forums/index....showtopic=37679 Quote Link to post Share on other sites
mark-tozer Posted June 12, 2011 Author Share Posted June 12, 2011 Thanks that was helpful. Im not sure wat fuel cut defender to get manual or electric and turbosmart or hks also are the hks afr any good as they go up in ones is that accurate enough many thanks Quote Link to post Share on other sites
Glanza_cl Posted June 12, 2011 Share Posted June 12, 2011 HKS or Jam will be your best bet. Quote Link to post Share on other sites
mark-tozer Posted June 12, 2011 Author Share Posted June 12, 2011 Is it true though that the hks one adjust all the settings before fuel cut and the turbosmart one only does it after fuel cut Quote Link to post Share on other sites
Glanza_cl Posted June 12, 2011 Share Posted June 12, 2011 The HKS does effect the whole range but with a RRFPR is allot easier to get reasonable fuelling as you simply up the rail pressure to compensate for the leaning out of fuel. I havnt used a Turbosmart FCD but its a clamp type FCD like Jam so will wait till it reads a certain voltage then hold it... The advantage with that is if you run a SAFC the fuelling is correct upto the point of clamping so all you have to do is adjust the fuelling from 0.8bar upto whatever boost you run (i.e. 1bar)they all have the same end result and you will never have a super smooth accurate map without a ecu but they do work.

Glanza_cl Posted June 12, 2011 Share Posted June 12, 2011 no probs , just dont slap on a FCd without fuelling mods and blow your engine lol Quote Link to post Share on other sites
mark-tozer Posted June 12, 2011 Author Share Posted June 12, 2011 No i wont i understand alot of people do that then give the fuel cut defender a bad name Quote Link to post Share on other sites
