  • What is the cheapest way to adjust a/f for these mods? I am very poor right now

    Hey guys.

    I have an R32 GTR with teh following mods:
    Apexi intake
    N1 turbos running 1 bar
    Full 3" exhaust including trust dump pipe and no cat
    Larger intercooler
    Oil cooler
    PRF6A-11 with .8mm plugs (I think I need to go to PRF7A)
    300 lph fuel pump
    Greddy Type RS BOV, changing back to recirc due to stalling
    Not sure about the injectors

    What is my best option to correct my heavy over fueling problem?

    I am hopeful one day down the road I can afford an HKS FCon Vpro 3.3 and a boost controller, but right now I literally have $500 to spend and that's credit anyway.

    I would love to be able to run a re-mapped ecu or something but there are o2 sensors missing etc. and I don't know if the stock ecu can handle it anymore.

    Any help is appreciated, I'm sick of not being able to drive this car.

    thats a rough spot to be in dude. all i can tell you is tuning pays for its self in the long run. i know rstuning on here prides themselves on tuning the stock ecu so you might want to look into that other then that 500 bucks isnt going to get you much in the way of tuning.

      That's what I figured. Sigh, I need to start saving up...

      I would love to buy an fcon vpro and boost controller tomorrow, I just don't see that happening for over a year.

      I know I could go the PFC route but the cheapest I can get one installed & tuned is $2,300 USD for D-JETRO and I was told it will still have problems with the ITB's. Whereas I could get an FCON VPRO fully converted to map sensors installed and tuned for $2,500... Plus I'll need a boost controller so I'm looking at closer to $3k... I've pretty much decided I want to go HKS but I am kind of stuck right now.

      I was also told not to go PFC route because it doesn't have knock correction, can only monitor it.

      I need a money tree. Nice car dude.

        story of my life. most of everything you said is true but a few things. yea the fcon vpro is sweet but pfc is cheap! 2300 is stupid for one even with install and tune. prime example i picked my pfc djetro bnib up for 600 bucks. which is a crazy good deal but still. i am going to install myself but my mechanic would prob do it for a hundred bucks. then average tuning is roughly 150-200/hr. so say your on the dyno for 3 hours which i would say is pretty average since you dont have any crazy mods. thats worst case 600 for tuning all in all 1300 and say 1500. shop around see what you can find. also yes the pfc cannot correct knock and it doesnt have launch control and a few other features but its been around for so long that its tried and proven. my justificaiton for the pfc is why mess with success?

              Remember that the F CON V PRO has to be tuned by an authorize HKS dealer... and they are rare in canada I think.

                I am pretty sure all the o2 sensors are ripped out of my car already... Where does the wideband go and once you go wideband do you only need the one controller vs. multiple sensors?

                Do you need a wideband if you are only tuning yourself or would it be a good idea to get one anyway?

                ---

                There is a very reputable HKS dealer who has worked plenty of skylines not far from me.

                Nistune is probably out of the question, I don't know anyone who can tune it in the states.

                I wish I could splurge on anything... Skylines depress me, everything is so expensive lol... I need to sell one of my cars.

                  Splurge? He JUST said he cant afford it.

                  Recoil,
                  Iam in a VERY similar boat right now. My car is has VERY VERY similar mods to yours and I cant afford a tune either.
                  But a gtrjon is SPOT ON with his comment about the tuning paying for itself over the long run. Hell it will even save you money.
                  I am saving up for a quick stock ecu retune over at RSTuning with Radek.
                  I spoke to him the other day and he was very very VERY helpful. He said you dont need to run an AFR for stock ecu tuning with him and if you can go to a shop that measures the AFR with their stock quipment, which is what he does. Also as for a boost controller, again not neccessary at this time if you boost holds steady. If it holds steady its no problem at all.

                  My best advice to you is do your research and look for a GOOD shop that will allow you to do this and tune your stock ecu right. I see you budget and thats around what it costs to have a stock ecu retune. Get that done, save up over time and get a PFC (my preferance) or the HKS FCon in your case and other mods and THEN get another tune.

                  Getting you car the way you want doesnt happen over night bro. Its a dream, give it time and youll get there.

                  Good luck man, keep us posted.

                  EDIT: If you look in the forsale section, there are a few guys selling Fcons and HKS piggybacks for very very cheap (~$250 mark)

                  EDIT #2:

                  The Wideband goes AFTER the cat IF you have one. If you do not have a cat, it usually goes into the testpipe. It is a very very good idea to run a wideband if you have some heavier mods. I have a wideband, but its just not installed yet. Since I run a cat, I cant quite afford to get it installed yet.

                    Thanks aN4rk1, it's a crappy position to be in.

                    I am overwhelmed with university bills lately... I do have a DD so I can leave the skyline sit, I just hate not being able to drive it especially when it is so freaking nice out.

                    I don't have a cat, and it looks like someone plugged the test pipe hole so I'd have to figure that out. My exhaust runs so hot I figured it would fry the wideband real quick... Maybe I'll have to buy a new straight pipe to even put a wideband in. Sadly I'm also trying to fix a minor exhaust leak at the straight pipe that shoots hot air up to the shifter boot and so the shift knob gets hot to the touch and burns you, might have to get it and the downpipe machined.

                      I don't think anyone in the US can re-tune stock ecu, and rstuning is about 8.5 hours from me so I'll be paying nearly what it costs for the tune in gas, plus I'll have to worry about crossing the border since the FEDS are trying to take all the skylines in America.
                      Bro I just got out of univ lol, so I know EXACTLY how it is! Thank the freaking gods that I was able to find a job so I can daily my Skyline, but even still, gas on her is a maaaaaaaaaaaassssssssssssssssive! My recent Facebook status:
                      At least my gas guzzling car is good for one thing...getting me 20 Airmiles everytime I fillup with Shell V-Power!!!

                      I feel you, trust me, let her sit for now. What year in univ are you in? It goes by quick man.
                      Finish up, save up, use this time to do your research and after build you car RIGHT the first time.
                      These things have so much potential its stupid.

                      Thats a really really tough situation man. What I CAN do is if you mail me your ecu, I can stick it in my car, get it tuned for you and send it back. And then you can paypal me or something you know? But It wont take your car to its full potential now because I still run stock fuel pump but everything is VERRRRRRRRRY similar as I said.

                        I only have 12 credits left but it will take at least one more year, and then I will have to study for GMATS for 3 months and then go to grad school for my MBA...

                        I feel lots of poorness ahead of me, and this economy F'IN BLOWS.

                        I so badly wish I could get a school loan and use the money from the loan to pay down my credit card and car loans but I need to do just that before I can even get approved for a school loan lol.

                        I'll think about sending the ecu..

                          I'll think about sending the ecu.. hell, I might as well just make the 8 hour trip up there. I'm worried 1-- I won't make it, 2-- customs will **** me up the ass, or 3-- there will be other **** wrong with it so it won't just be a day trip.

                          Oh, and i need a passport too. DOH.
                          Thats not too bad man. 1 year + 1 year for MBA will FLYYYYYYYYYYYYYYYYYY by trust me man. I went through 4 years of regular cirrculum, 1 year of internship, and ANOTHER year of taking extra, repeat, and other courses. Ive wanting this car since I was 16 and I was FINALLY able to do it a year ago when I was 25. Just remember, your going to school for YOUR betterment. I encourage EVERYONE to do it! Yes there will be a little bit of poorness ahead of you, how do I know this? I just got out and Iam poor lol. Like I said, this DOES NOT happen overnight, save save and SAVE! My gf is just entering university, she told me during her last year for me to go back to do my MBA. Two full grown adults in school, with a gas guzzling car, surviving on student loans, how rich do you think we are going to be then lol. But I know after its smooth sailing so just hang in man. Plus I know school in in the states is 1000000000000000000000x more expensive then here.

                          ANYWAY BACK ON TOPIC:

                          Yea think about it and let me know. Iam pretty much on this forum 24/7, shoot me a pm or whatever. The trip is risky, your biggest concern in my opinion is customs at the border being total jerks. But depends where you cross, if you come up in BC, you SHOULD be ok. DO. NOT. EVEN. THINK. ABOUT. CROSSING. IN. ONTARIO.

                          EDIT: PM dude !!

                            Sorry to go OT but I would be weary about going for a MBA immediately after undergrad right now, there are a ton of unemployed people out there right now who already have relevant experience and a MBA. It is a saturated market at this point and it may not be the best idea to go and spend $60K on a MBA if you wont be able to get a job to pay for it, maybe wait a year or two for the economy to improve before going back. Just my two cents.

                              I hear that, but most are also older. I have the experience, and what better time to go to school then when you cannot get a good job?
