I've got a tuned powerFC but the car is running rich. I'm getting poor mileage, even when I drive like a granny, normally 300km to a full tank.

Car is an R33, mods are - PowerFC, AVCR set on 1.1 bar, HKS GT2535 and 550cc injectors.

Question is - with a tuned powerFC, to get it 'tuned up' is it basically a full re-tune, or would it just be a simple task to check the AFR's and make the necessary adjustments. In otherwords, am I looking at $100 or $500?

Looking at getting it done a Morpowa, as I'm up north and that is where the car was tuned previously (before I bought it).

if you go to Morpowa you will be paying top doallar from what i have heard.

I reckon its gonna be classed as a full re tune but not 100% sure.

Give Fours N More a call, they deal with aftermarket computers alot, moreso microtechs, but still know their stuff about Power FC. Talk to Brenton or David there and they will be able to give you some good advice. Tell them Luke with the R31 reccomended you to them, he might help you out a little more.

at Morpowa it only cost me i think between $250-$300 to tune it and that was for tuning my forged 300rwkw engine

i took mine back there to get my power fc tuned in august coz it was running rich, they ran it on the dyno and checked the air/fuel ratios then adjusted accordingly and they can even change your boost setting aswell if u want as part of the price, its not a full retune that u need and it'll take about a half a day, simon and the guys are really helpful there and do great work, sometimes its worth paying that little extra 2 get it done right....(trust me i know coz a certain workshop blew my old engine while trying to tune it on the dyno and leaned it out), they also test ya car on the road and not just on the dyno and check your knock levels

Thanks for the suggestions all. I think the O2 sensor is ok, because I can see it going up and down between 0.2v and 0.8v on the powerFC handle controller, which is supposedly what it should be doing under normal operation.

I dont know if its me but's whats on your plenum :)

Did you add the goodies after purchase? if not check if Morpowa still has your tune on file with those mods & have a look at the AFR. Then have Simon or Drew re-tune it.

Several mates w/ Skylines & myself have used Morpowa then Boostworx - personally we've found Shaun the better tuner. Even though I'm only 10mins away from Morpowa the cruise down to BW is worth it as iLEC mentioned.

Just get the O2 sensor checked out, or just replace it anyway cos it's probably shot and causing your bad mileage. There is a way to convert a universal sensor i think, do a search.

Just waht i was going to say...might save you some money.

the plenum has been modified, so the throttle body is at the front instead of the side to shorten the length of the intercooler piping...

-1000000

but boostworx dont ring you straight away after they have blown your engine up on the dyno they wait 4 you 2 ring them, especially just after i spent $13,000 worth on boltons from them and then have them leaning out the engine and blowing piston 6 ringland, they put way too much timing in and i had 2 keep going back every week until they blew the engine...

not F**ken happy!!!!!!!!!

so there is someone on here that opposes boostworx, i thought 95% of ppl on here would say that boostworx should be the only place to take your skyline by the sounds of things.

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
