200sx-Starlet-Jay Posted January 4, 2009 Share Posted January 4, 2009 hi all.when i drop fte in my car, i know im guna hit fuel cut. but i read somthing tonite that got me thinkin. how can i avoid fuel cut? ive seen a HKS FCD that im probably guna buy.. but ive seen loads about them being bad. last thing i want is to mess my car up. i will also be running a HKS actuator and an ebc. can i not just raise the actuator setting to just over a bar, then run the EBC at just under a bar or a bar on its very highest setting i would use? or do i need to aproach it with the FCD?Jay Quote Link to post Share on other sites
Kennedy Posted January 5, 2009 Share Posted January 5, 2009 BUMP..becuase i could do with the same info Quote Link to post Share on other sites
montanajr Posted January 5, 2009 Share Posted January 5, 2009 Why are you sure you'll hit fuel cut? Will you have air filter/exhaust/de-cat? You can avoid fuel cut by porting the wastegate, introducing a restriction to the intake or exhaust (standard CAT back in, or standard air box). I'd say set your actuator to 0.6Bar then use your EBC to raise it to 0.75 - just below fuel cut. Also an aftermarket manifold will help slightly I found. If you want to run 1Bar then you will need a FCD, but you'll also need to ensure the additional boost is being fuelled for correctly. This requires a RRFPR. You can use this FCD/FPR combo but its crude, I would suggest setting the FPR fairly rich then getting a SAFC to trim it down throughout the rev range (should be setup on a dyno.) Will give you a pretty good tune, and is the next best option to an Emanage or equivalent.EDIT:Also, a HKS FCD will be fine as it leans out the entire rev range, which you can then use the FPR to compensate for.Hope that helps.

Glanza_cl Posted January 5, 2009 Share Posted January 5, 2009 ^^ summed it all up, and just to let you no a ebc can not lower boost only raise it so set your actuator at something low like 0.5 then increase it on the ebc.if you want to run around the 200bhp mark which expect you do then i would invest in an emanage, you can set your FCD up but you will need a RRFPR so you dont destroy your pistons running lean. but there isnt much difference between running under fuel cut at 0.8 and running 1bar and potentially blowing your engine.i would wait be patient and invest in an emanage or as stated above get a SAFC and get it all set up together.

Pav Posted January 5, 2009 Share Posted January 5, 2009 The core of the problem is boost creep (boost rising over the target level set by the actuator or boost controller). Messing around with air intakes and cats is far from an ideal solution, you want to make your car peform better not slow it down lol. Unfortunately the truth is to truely stop boost creep (which is a bigger problem than just fuel cut. Trying to map an emanage or other ecu with a boost creeping turbo is not easily done) you have two options.1. Save your pennies and either have the wastegate professionally ported which means removing the turbo (you can do the whole job yourself but have to be very careful), OR 2. Save your pennies and get a Hybrid turbo. Part of hybridising a CT9 involves porting the wastegate area, not just the round hole but the area behind it to allow the excess boost pressure to escape problem free.

Steve GT Posted January 5, 2009 Share Posted January 5, 2009 HiI've been wondering the same thingif your going to increase the boost above the 0.8bar cut off my mate says you just uprate all the fuel system which will solve the cut off problemIs this true??? Quote Link to post Share on other sites
Glanza_cl Posted January 5, 2009 Share Posted January 5, 2009 you need a FCD(fuel cut defender) a RRFPR(rising rate fuel pressure regulator) at a minimum but i would be advised to get some kind of advanced fuel management e.g. Apexi SAFCit's been covered a million times just have a poke around in the technical section Quote Link to post Share on other sites
Steve GT Posted January 5, 2009 Share Posted January 5, 2009 Thanksso getting like a Sard Fuel Pressure Regulator Package Full Kit and getting it set up on a dyno wouls solve the fuel cut off problem Then??? Quote Link to post Share on other sites
BlackRocket Posted January 5, 2009 Share Posted January 5, 2009 Like was said earlier, I'd stick at 0.8 on the standard CT9 as the gains between 0.8 and 1.0 bar are very little and IMHO its worth it for the health of your engine.Thats what i'm doing until I can afford to change the turbo to one with an external wastegate etc and proper managementSteve Quote Link to post Share on other sites
Steve GT Posted January 5, 2009 Share Posted January 5, 2009 So I've gt a pretty standard EP82I havn't had it long all I've done is A blitz SUS induction and Blitz Dump Valveafter doing exhaust FMIC etc i intend to increase the boostso what your saying is but a Fuel Pressure Regulator kit, get it set up on a dyno with a HKS FCD then with a Adjustable actuator up the boost to 0.8bar on the standard C9 turbo??have i got that rightthanks Quote Link to post Share on other sites

BlackRocket Posted January 5, 2009 Share Posted January 5, 2009 So I've gt a pretty standard EP82I havn't had it long all I've done is A blitz SUS induction and Blitz Dump Valveafter doing exhaust FMIC etc i intend to increase the boostso what your saying is but a Fuel Pressure Regulator kit, get it set up on a dyno with a HKS FCD then with a Adjustable actuator up the boost to 0.8bar on the standard C9 turbo??have i got that rightthanksYeah.First things 1st make sure the standard engine is running well. Do a good service and put in some NGK or the like Spark Plugs.Then sort out the basics first (Exhaust/ Filter/ BOV if you like) then move onto extra power.Remember that its best to play safe as you don't want to blow your turbo Power wise my car has a relocated Apexi Filter, TRD Stainless Steel Exhaust, HKS Adjustable Actuator and Blitz Electronic Boost Controller to start with.I am waiting to fit my HDI FMIC, Coilovers, SPS Manifold, New Disks and Pads, Adjustable Panhard Rod etc so that when I raise the boost the rest of the car can handle it.I would also make sure you have good suspension, brakes and tyres as there's no point spinning all that newfound power away or not being able to stop!!Just my 2p worth Steve Quote Link to post Share on other sites
200sx-Starlet-Jay Posted January 5, 2009 Author Share Posted January 5, 2009 well basicaly the car will be running with following modsaftermarket exhaustblitz decataftermarket manifoldtoy tuning filter relocation kitht leadsblitz dump valvengk iridium 7'shdi front mounthdi electronic boost controllerhks actuatorhks fcdafter market fuel pumpRRFPRso if i get it set up corectly on a RR, what boost do you reckon i would be aiming for reliably? or could i just ask the RR geezar to take it anywhere up to a bar, but only of reliably possible?Jay Quote Link to post Share on other sites
keirz Posted January 5, 2009 Share Posted January 5, 2009 jay, get the fcd, rrfpr and fuel pump all off your list. dont even bother with them. take the money you was gonna spend on them and get a jam ecu. 5 minute fit and will fuel up to 1 bar easily and will benifit from a more agressive map. thats my opinion from my own experience. i made good power that way.add a good hybrid to that list and you will be around 200bhp. if you need a go in my glanza to prove this is a good route to go just let me know!

Although lookout for a Blitz Access one too as they are awesome ecus. I had a Jam one which seemed to perform well but my topmount was bottlenecking performance at the time so I sold it to buy an fmic. Once I had a Front mount I bought a Blitz Access (does much the same job as Jam/Sard/Zep ecu). I am told Blitz created an extremely good ignition map for they're ecus. The difference from 0.8 bar on standard management was incredible, absolutely nuts @ 1 bar on a hybrid! Keirz setup is similar to mine so if you check his out, I doubt you'll be dissapointed Fuel regulators seem like the cheap option at first, but once you've bought a decent one plus an FCD plus RR setup costs, you might as well have bought an Ecu!

Pav Posted January 6, 2009 Share Posted January 6, 2009 Or go for an externally wastegated setup; should help.Yeah thats a good option I didnt think to list. I looked into doing this myself but for the expense of a manifold and Tial WG I realised buying a hybrid would cost a similar amount. Quote Link to post Share on other sites
Glanza_cl Posted January 6, 2009 Share Posted January 6, 2009 All the information you could wish for Jay is here buddy, there is some great advice but it is completly up to you to which direction you take but just remember the petential consequences of a FCD. Quote Link to post Share on other sites
Steve GT Posted January 6, 2009 Share Posted January 6, 2009 im kind of in the same boatwas thimking of FPR's FCD's and getting it set up on a RR but then realised an ECU was a better optionbut I've looked everywhere for 1 theres one or 2 kicking around on forums but is there ne where else you can get them from???

Steve GT Posted January 6, 2009 Share Posted January 6, 2009 yer mate thats what im doing I've been told by the boys on here to either get a Blitz access ECU or an E0anage if that helps you Quote Link to post Share on other sites

Glanza_cl Posted January 7, 2009 Share Posted January 7, 2009 i personaly am going emanage, but if you find a jam or other such type then get it, but i want the adjustability of a emb personaly. Quote Link to post Share on other sites
himmys gt turbo Posted January 7, 2009 Share Posted January 7, 2009 hi guys,I have a 95 GT with a hks filter, hks exhaust, bailey BOV, and a de-cat and i am getting a fuel cut off when i'm at full boost, but it only happens sometimes?? i'm gonna get a front mount in the next couple of weeks and a HKS actuator and i think a re-map with a piggy bank ECU on the RR should sort the problem??cheersjay Quote Link to post Share on other sites
