scottieboi94 Posted April 9, 2014 Share Posted April 9, 2014 Hi everyone, I am running a speedvision ct9 turbo at 0.95, what bar should my fuel pressure be? Thanks Quote Link to post Share on other sites
TrisK Posted April 9, 2014 Share Posted April 9, 2014 Massively depends on the car. You need to go on a rolling road or get a wideband afr guageStandard fuel pressure is 2.4 barIt should be set at idle wth the vacuum disconnected Quote Link to post Share on other sites
scottieboi94 Posted April 9, 2014 Author Share Posted April 9, 2014 it was on 5 bar, obviously this was too much it has been turned down to 3bar with vac pipe on Quote Link to post Share on other sites

scottieboi94 Posted April 10, 2014 Author Share Posted April 10, 2014 ok cheers, I was only wanted to if putting it down from 5 bar to 3 bar was fine? i have a jam ecu that controls the fueling, was just wondering about the pressure Quote Link to post Share on other sites

scottieboi94 Posted April 10, 2014 Author Share Posted April 10, 2014 Does a wideband just tell me my ratios or does it adjust fuelilng aswell?doesn't jam ecu control fueling anyway? Quote Link to post Share on other sites
mikey4410 Posted April 10, 2014 Share Posted April 10, 2014 it will show u ure ratios.u need to aim for 11.5 afr to be safe orto be super safe 10.5-11.0both these afrs are at WOT Quote Link to post Share on other sites
mikey4410 Posted April 10, 2014 Share Posted April 10, 2014 and yes a jam does have something to do with fueling as does the stock ecu dude lol.but none of the above ecus have an lcd screen with an afr shown at anytime built into them :-D Quote Link to post Share on other sites
scottieboi94 Posted April 10, 2014 Author Share Posted April 10, 2014 Do you have to weld them on? and i meant jam ecu raises fueling to cope with the power it gives Quote Link to post Share on other sites
mikey4410 Posted April 10, 2014 Share Posted April 10, 2014 yes a wideband requires a bung welded in mate.around 36 inchs from the tuby Quote Link to post Share on other sites
RobSR Posted April 10, 2014 Share Posted April 10, 2014 You've asked this question for the last like week lol. Put it to standard fuel pressure! Thats what the JAM ecus are set for! Quote Link to post Share on other sites
dangeestarlet Posted April 10, 2014 Share Posted April 10, 2014 Just put a standard fpr on or set it to standard fuel pressure 2.4bar Quote Link to post Share on other sites
scottieboi94 Posted April 13, 2014 Author Share Posted April 13, 2014 ok i have it on 3 bar atm, has to be better than 5 lol Quote Link to post Share on other sites
richardc9052 Posted April 13, 2014 Share Posted April 13, 2014 Why ask the question and then blatantly disregard what everyone says? You obviously dont want to listen so why as the question numerous times just to get the same answer and ignore it??? Quote Link to post Share on other sites
Dean_mc88 Posted April 13, 2014 Share Posted April 13, 2014 Invest in a wideband, and start at standard fuel pressure like its been said a number of times lol Quote Link to post Share on other sites
scottieboi94 Posted April 13, 2014 Author Share Posted April 13, 2014 I will put it on standard fuel pressure, I was just saying for the past few days it has been turned to 3bar which is better than 5, that's all I was saying....:L Quote Link to post Share on other sites
richardc9052 Posted April 13, 2014 Share Posted April 13, 2014 I would advise just putting the standard fpr on.. you cannot go wrong then Quote Link to post Share on other sites
