hey guys my i found a HKS fconV the other day in my gtr it still has the standard computer and that wired as well so im guessing its a piggy back. Is it tunable? also there are two plugs on the back of it, what connects to them(inserted pic) ?

Thanks :wave:

dont qutoe me but i dont believe many tuners/workshops have the ability to tune a fconv in australia. maybe call a hks distrubotor in your stateto see who may have the software and ability to do so......

Sydney,

and bd4's are the ones to speak to.

but sas can borrow software and crodon too i beleive?

other than that its kinda like a fully controlable piggyback. the standard is left to control all the a/c and other things... i think!!

hks fcon great computer if only there were more people here to tune them

CRD doesnt tune the the fcon no more.

its not a piggy back at all, you can run it standalone but as mashrock said, the standard ecu is there for A/C and 1 other thing i cant recall

also are those 2 plugs male or female??

if they are female and small they could be the wires for the air temp and map sensors as they are an option

Also.

from what i have been discussing with the uk blokes.

the hks navigator pro can tune the fcon V pro.. But you must be updated to the latest version

i'm waiting to hear more on this topic and i'm waiting on a preview/video on how its all done.

the plot thickens!

bd4's can update your software to the latest they have..

i prefer to leave the tuning to the pro's

bd4's will promise you that if there is any probs with their tune later down the track for no apparent reason they will fix it for free

yeah when i have eveything all together. and i am in need of a tune i'm booking it in.

but also will get the navigator pro as its only 3-400 bucks. and also does a bunch of other things.

I'm sorry was it tuned in japan for australian fuel and all the mods on the car?

what is the price difference between retuning a standard ecu compared to a aftermarket unit??

have u had experience with both? if so please provide us with you breakdown of cost

well if you have access to a free dyno then congrats..

for everyone else?? can you provide us with a $$ cost?

and your worshop recommends a remap over a aftermarket ecu? good luck with that..

i have dealt with both senarios and can say from personl experience, both performance wise and cost wise.. and aftermarket ecu is the go

$595 for chip and $200/hr for dyno tune. Hmmmm let me see, compare development costs of a particular ECU made by a manufacturer for a particular car compared to that of an aftermarket ECU for a range of cars. I bet the devlopment cost for the aftermarket ECU to cover a range of cars is not within 1/5 of the development costs of the standard ECU produced by a team of engineers for that car.

When you've tuned both you can make that assumption and I've only come to this conclusion.

so what your saying is that a standard ECU is perfected over a long period of time by a team of engineers..

then you have a aftermarket ecu which is also reasearched, tested etc by engineers for a 1/5 of the time..

then you have some worshop who remaps a perfect ecu over only a couple hours supposedly making is better than what those engineers can?

fact: if a standard remap is better and more cost effective then why isnt it everyones number one choice??

Try reading it again - cant make it any easier to understand.

How many tuning shops in Australia know what they are doing or even have the ability to properly emulate and tune the factory managment? It is for this reason alone that it isn't more widely done. Remember nissans aren't the only cars that can be chipped or the standard managment reprogrammed.

are you trying to make your point or make excuses?

your right!! not many shops can emulate and in this case we are talking about skylines only..

what are the advantages again??

No. My point is I believe that the standard managment addresses all operating parameters of engine management better than most/all aftermarket ECU's.

      I drive the Tiguan much harder than the Skyline in all conditions, because it just grips and hooks, unlike the R33 shit box

      The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.

      When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.

      Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.

      This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
