hi everyone

just wondering if there are any good books or websites out there that people have used that are great for learning everything about tuning. wanting to learn more the theory behind it all. i do know some basics but want to be more informed when talking to my tuner. i currently have a hks pro v, so unfortunately i cant do any tuning myself but still want to know more.

also are there any good threads on this site specific for tuning rb26.

cheers

ben

unfortunatly there is no guides for dummys or "how to tune" documents. you have to pretty much work it out yourself, and don't bother asking other tuners because they seem to like to keep what they know to themself's for some reason.

so this is what you need,

aftermarket ecu thats tunable with laptop

laptop

12v to 240v inverter

wideband afr setup

and alot of balls because if you stuff up then you have a broken engine.

good luck

in my history of tuning i have only had 2 motors with issues, they were both built by the same dodgy builder. One of them spun a bearing about 6 months after the tune and the other had bearing issues after being on the dyno for around 20 minutes or so due to oil issues.

I have a good friend who is a tuner, and without him there is no way i would know what i know today and he always pointed me in the right direction to learn, 90% of the time he would not give me answers but give me tips on how to find the answer because you do not learn when someone tells you all the answers.

Excellent thread, i've been considering the same thing myself, just picked up a datalogit for my pfc so thats a start... although i didnt thinkabout the inverter for the laptop... i guess i will need a few hours of battery to do things properly.

As far as the other kit you mentioned GT are there any specific bits of kit you'd recommend. I noticed you seemed pretty happy with the gizzmo knock amp thing (cant recall its name).

Would you say one of these is a must. Also if i'm looking to consider the emmisions side of things (lets say i wanted to do an emissions friendly tune for if i get epa'd) do you have any thinoughts or suggestions on what to look at in that area.

Much like you mentioned i'm looking for guidance as opposed to outright answers. I'd much prefer to understand what i'm doing as opposed to doing it because someone told me to.

Someone mentioned the motec stuff above (courses knowledge base etc) does anyone else have any other resources they care to share.

I know that this or last months HPI magazine had some tech articles on tuning.

yeah i know things like that arent cheap. but i prefer to spend the cash in the right place and learn to do things properly.

I figure that if i'm willing to risk my engine learning least i can do is spend some cash on some kit to help me detect bad things.

Gizzmo K-mon costs about $1200 retail. I suggest you buy a Techedge AFR meter first, www.wb02.com.

You don't even know how to tune yet and your talking about passing emissons test? you need to learn how to crawl before you can run a marathon mate.

After you have tuned about 20 or 30 cars then you should try and work out how to get into the advanced stuff otherwise you will never get anywhere.

Good luck with it.

Yeah thats not cheap at all... and they dont have it in the colour i like... AFR it is then :P.

As far as basic compared to advanced tuning tasks go, i understand that tuning to a goal, be it max power or lower emissions isnt as simple as sit down plug in and away you go. But i normally find that i learn best by applying what i'm learning, can you suggest any tasks that would be good when tuning purely for the sake of learning? it seems that without a dyno tuning for power isnt sane and that basing the results on seat of your pants feeling isnt all that empirical. Would detuning for different fuels be classified as a big job eg down to a safe tune for 95 octane then back to a safe tune for 98??

What were the milestones you set yourself when it came to learning???

have a look at this thread, http://www.skylinesaustralia.com/forums/Ro...d+tune+power+fc

that was when i first started, i just wanted to learn how to tune my own car to save on tuning costs and it just exploded to levels that i never even thought about reaching.

the first task for you mate will be to re-set your power fc. and re-tune it completly from scratch without blowing it up.

If you succeed then do mods to your car and re-tune to suit. I only suggest playing with your own car before you start tuning other cars

Cheers GT, that sounds like a plan to me. I can always save the current tune to the laptop anyway if i need to go back to a known safe point.

Regarding safety margins, is the knock meter on the pfc up to scratch when it comes to tuning and can its reading be trusted?

From reading, most guides seem to say "alter timing and fuel until knock is detected and back off 3 degrees or so " or something similar. If the pfc's knock meter is rudimentary at best i'm worried that by the time i pick up that its knocking the damage is already done... even if it is below say 20.

    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • 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.
