scottieboi94 Posted January 25, 2014 Share Posted January 25, 2014 (edited) My Glanza is ovefueling, some of my mates have said they have smelt the petrol coming off it when I've been driving it. I have a sard fuel pressure regulator with a gauge that reads between 60-75 psi when the car is running. As far as I know this is way to high psi for what i should have, I should be running between 40-50 as a guess, I'm running ct9 hybrid, blitz Decat, jam ecu probably pushing around 180 bhp anyone know what psi I should be running thanks, I recorded 220 mile on full tank which definitely isn't rite :L Edited January 25, 2014 by scottieboi94 Quote Link to post Share on other sites
TurboTobz Posted January 25, 2014 Share Posted January 25, 2014 4-6bar on a ct9.... who tuned your afr's scooby doo? What boost are you running? Quote Link to post Share on other sites
TurboTobz Posted January 25, 2014 Share Posted January 25, 2014 Easiest and safest way is to bring yoyr boost down to a safe level and return fuel pressure to stock level of 2.4bar ish this way the ecu can calculate it's afrs safely at stock levels without putting a huge strain on pump and injectors Really though best ideas for your to take it for a health check on a dyno Quote Link to post Share on other sites
mikey4410 Posted January 25, 2014 Share Posted January 25, 2014 u need an a/f gauge. imperative bit of kitthen u wouldnt wonder whats what turbo cars smell of overfuelling which is normal. Quote Link to post Share on other sites
TurboTobz Posted January 25, 2014 Share Posted January 25, 2014 regardless at 4-6 bar he's a 'tad' rich lol Quote Link to post Share on other sites
scottieboi94 Posted January 26, 2014 Author Share Posted January 26, 2014 So what is 65/70 in bar? Am I over fueling very badly? Can I adjust the fueling on my fpr, is it safe to drive? Quote Link to post Share on other sites
TurboTobz Posted January 26, 2014 Share Posted January 26, 2014 Set boost to .7 and fpr to 2.4b.Your heavily overfuelling I don't know how the plug and plays work so set it to factory spec ecu fuel pressure and boost then get a professional to tweak it Quote Link to post Share on other sites
Beastmode panda Posted January 26, 2014 Share Posted January 26, 2014 So what is 65/70 in bar? Around 4 bar. Quote Link to post Share on other sites
Zeldoz Posted January 26, 2014 Share Posted January 26, 2014 You must've been popping and flaming like MAD Quote Link to post Share on other sites
TurboTobz Posted January 26, 2014 Share Posted January 26, 2014 So what is 65/70 in bar? Am I over fueling very badly? Can I adjust the fueling on my fpr, is it safe to drive?4.5 and 4.8 bar pretty much Quote Link to post Share on other sites
scottieboi94 Posted January 26, 2014 Author Share Posted January 26, 2014 It has been popping a tiny bit but not much, can I adjust the fuel pressure on fpr? Quote Link to post Share on other sites
TurboTobz Posted January 26, 2014 Share Posted January 26, 2014 Yeah think its a 12mm nut on the top of the nipple sards use Quote Link to post Share on other sites
AdamB Posted January 26, 2014 Share Posted January 26, 2014 Plug and play ecu's like to run base fuel pressure 2.4 bar and they just adjust the injector opening time accordingly. Quote Link to post Share on other sites
scottieboi94 Posted January 26, 2014 Author Share Posted January 26, 2014 I would use the jam Ecu fueling but someone told me that the sard for would be better? Would it be safe just to the pressure down a bit on fpr? Quote Link to post Share on other sites
TurboTobz Posted January 26, 2014 Share Posted January 26, 2014 Fpr pressure to 2.4bar Quote Link to post Share on other sites
mikey4410 Posted January 26, 2014 Share Posted January 26, 2014 thing is all cars are slightly different all cars fuel pressure setiings will vary theres so many varients fpr,fuel pump wear etc etc you cant be sure unless you monitor a/fs DONT GUESS STUFF...its costly Quote Link to post Share on other sites
TurboTobz Posted January 26, 2014 Share Posted January 26, 2014 It's a much safer option running 2.4bar and standard boost. Quote Link to post Share on other sites
scottieboi94 Posted January 26, 2014 Author Share Posted January 26, 2014 Gonna sound thick but what's a/fs? Quote Link to post Share on other sites
TurboTobz Posted January 27, 2014 Share Posted January 27, 2014 Air:fuel ratio Afr af afs etc Quote Link to post Share on other sites
scottieboi94 Posted January 27, 2014 Author Share Posted January 27, 2014 How can i monitor that, is the best way to go to sort it out or should i go to a specialist? Quote Link to post Share on other sites
TurboTobz Posted January 27, 2014 Share Posted January 27, 2014 Judging by your knowledge you've shown I'd take it to a dyno mate. Only way worth monitoring afrs are with a wideband kit not cheap atall but can save you an engine Quote Link to post Share on other sites
scottieboi94 Posted January 27, 2014 Author Share Posted January 27, 2014 Oh didnt realise it would cost a lot to monitor a/fr, will take it to a dyno mate, would you say i need to take it asap or is it not that bad atm? Quote Link to post Share on other sites
Turk Posted February 3, 2014 Share Posted February 3, 2014 Well if you havent blown your engine yet. Your fine for now. Get a wideband lambda sensor with a gauge and controller. Innovate lc1 isvery good. Can get them brand new on ebay for about £150. And on boost your afr should be about 12 to be safe. Anything higher can be a little risky. Hope that helps. Read up on this stuff before you buy anything or change the fuel pressure. Its better to run rich so your engines safe from detonation. Quote Link to post Share on other sites
Chris_GlanzaV98 Posted February 3, 2014 Share Posted February 3, 2014 Not being cheeky mate but you dont sound to clued up, get it to a good tuner with proper fueling equipment and have themCheck it out Quote Link to post Share on other sites
AdamB Posted February 3, 2014 Share Posted February 3, 2014 Well if you havent blown your engine yet. Your fine for now.May well not have "blown" it yet, but with that much fuel flow and little air you can bet the engine is getting bore wash. Not lubricating the piston assembly correctly and contaminating the oil taking away its lubrication properties is a risky game. Quote Link to post Share on other sites
