Duty setting? For the life of me i cant see how ppl get it SO wrong as to affect the response of the motor like experienced here. Im not saying anyone is right or wrong, just pointing out that its very surprising that its the settting of the EBC. Without even knowing what i was doing i got my AVCR almost spot on. After reading the manual i was able to get it spot on...and have since helped a few friends out with getting theirs to work top notch. They were all singles though so that could be the reason????

Interesting :P

quite easy to get incorrect setting...the car i fiddled with at the dyno day only had to have duty adjusted by 5 or so i.e. from 55 to say 60. Id say in Justins case it was a little more than this. Roy sometimes people don't do the simple things right....reading the instructions, finding out and understanding how a product actually operates goes by the wayside.

OK we found the boost controller unable to keep up with the rpm's, something like that. It also had a hard time holding consistent boost.

Re-checked cam timing. All good.

We've ripped out the AVCR and put in a Blitz boost controller. Will be more testing and tuning tomorrow and will report back!

good stuff. the blitz controllers are very good. but I still have a soft spot for the profec BII. check out my boost curve on page 4... they really are good value for $$.

can't wait to hear the results. :(

edit: now you can sell the AVCR to Roy. He loves em.

well they only go up to EVC 4, but for some reason americans call them EVC5. (nfi why). "Blitz" runs one in his built and tuned 33 GTR and it seems to be pretty good. It's pretty well accepted that the Blitz SBC ID III is #1 with HKS EVC IV a close second, or in some peoples eyes it's the other way around with the EVC IV on top.

but I would try and 100% establish what your problem is before running out to buy another EBC.

OK EVERYONE HERE'S THE UPDATE!!!

Took the car to HITMAN (Matt) today. Super cool guy! First thing he did was just a dyno run and guess what? We got 321kw at the wheels with Indy's tune.

OK, hitman's dyno is a 2WD dyno, Indy's (IS Motor Racing) is a 4WD. It looks like there's the reasoning behind the power figure difference.

After a lot of playing around with the cam timing we brought the power down to 293kw at the rear wheels but the power is coming on a whole lot earlier. Lots of mid now, a lot more like BeerBarron's dynograph, also with a very very stable boost line too.

I took the car straight to Indy's dyno again after hitman, same day and we dyno ran a 266kw at all fours! So that 293 on hitmans is 266 on Indy's.

So, go figure? Car feels damn amazing now though, so much response WHOO HOO!

I don't care too much for the power up top, but I'm loving all this power in the mid range. Perfect.

So to you have 2 main problems at the end of the day

1/cam timing

2/boost controller

is this correct?

The dyno figures make sence as one is 4wd and one 2wd and you will always have more losses on the 4wd dyno (if you run it in 4wd that is)

Can i ask what the cam setting were and where you moved them to as i have been pushing guys to tune cam on the dyno for a number of year as you can really unlock some real power doing so and i think you have done the right thing in tuning for mid range as it make it a nice car to drive and alot of fun

Great work enjoy

pete

Hey Pete,

I ain't sure of the cam timing values. I'm not that technically minded!!! But yes it was all the cam timing. I don't think it was the boost controller at all as hitman says he likes AVCR's.

I've ripped mine out though so will be selling it asap.

oh ok well let me know what you want for it as need one for my second project (drift car)

Glad you found the problem and i thought in my first post it was cam timing as it has a hugh influence on the motor characteristics.

pete

good stuff. glad you got things sorted out and that you enjoyed going to matt. he is a good guy and personally I've never had a problem with his tuning.

now post that graph biatch! :wave:

Feels a bit scary now in all honesty. Will wait for a track day, got done for 3 points today in the EVO. Damn it. Time to slow down and see the year out :laugh:

Less talk, more GRAPH!!! :)

bummer about the points loss. definately need to watch it over the christmas break as they will all be out clocking up overtime and need the fine revenue to justify it.

  • 1 month later...
Will not be posting the graph in a hurry dude. It's in my car which is in a workshop getting some trust rear pods painted and fitted >_<

Wondering if you had a chance to get that dyno graph mate, interested to see the power curve you got there

Here you go:

Amazing difference, it's a whole new car. Amazing at Eastern Creek last week. I did a 1.54 without even trying and that was in traffic too. Very happy with the power now and amoutn of mid range, just needs suspension tuning now as my brakes are going on too! SO MUCH POTENTIAL!!!

Awesome result Justin! I think youve just confirmed which turbos i'll be looking at in the near future, comes on early and yet has 250kw + from 130 to 200 kmh. Thats alot of area under the curve = fast car :D

What brakes are puting on by the way (just curious)?

    • Because all parts that are put into your papers usually are assigned a badging if they did not come with one. So other people can just check that badging to tell if it is the parts your papes outline. But my pipe has NOTHING on it whatsoever. No idea why this even passed as a Mines pipe to begin with. I see this going two ways: -nobody cares and it's a non-issue, but that is unlikely -the pipe will just have to be assigned a bagding, for sake of argument, a Mines logo, and the papers corrected accordingly If it interests you I will post what the actual solution ended up being. All I care about is that it has to sound equal length and nobody can screw me later on because of a pipe being illegal.
    • The fasteners to the pipe are not subject to TÜV I guess, if we really start putting nuts and bolts through technical tests I'm going to hang the people responsible and then myself. Usually on a modern-ish EU normed car, you would just replace the pipe. Because if you start hacking away at it and welding new pieces on the cops will definitely find a reason to tow your car. That is just how it is sadly. On old cars and imports with no clear "standard" stuff like that won't matter too much. Most cops or inspectors probably won't even really know what they are looking at. But there is experts for this stuff even among cops, and some of them know the rules to a T and even have extensive knowledge about many vehicles. For "just a pipe" to be legal it usually is included in a set of parts, like a complete intake kit or a full exhaust. For example my exhaust needs to pass a noise test, meaning they have a standardized test track with a set of instructions and they run the car through there 3x for an average noise value that is 75dB(a) at point x of the test track. If it's above that, fail. For a turbo setup to be put in your papers you have to do dyno runs, emissions testing etc. So quite costly
    • Would this not be the same for the exhaust you've posted up?  If your exhaust volume and emissions are fine, why does the brand of pipe matter? 
    • The issue is more the fact that there is inspectors that deal with japanese cars a lot and they might know what a real Mines pipe looks like. And then they're gonna get antsy and not pass your car. But I'd have to talk to one of them about this, because you know as well as me that it's just a damn pipe and it effectively doesn't do anything. As I need to have my GT2860s and my exhaust setup (and the increase in HP) TÜV'd anyways maybe they can just correct the entry in the papers or assign a badge to the front pipe. I'm no expert either though, will inquire about this.     Thanks for the insight. Not sure if having a custom made pipe is good or not. Will find out in due time I suppose. Would be kind of funny if this was made in Germany though.
    • See this is a really tricky topic as technically the same rules apply to all cars but for cars but there is a difference. If you want to modify a car like the Skyline which never existed here you have a bit more freedom as they do not adhere to EU specs anyway. Any modification you do has to be in dividually checked anyway so as long as one of the inspectors think it's ok and within the TÜV ruleset you can get stuff like a top secret rear diffuser put in your papers. Which frankly would need a shitload of tests and certificates for EU spec cars, like a 2010 BMW M3 for example. But if you DO run these tests and all tests come out ok (safety stuff for the most part) there is no problem running such a part legally. It's just way too expensive to do for a single person on one car. The most touchy parts are emissions related mods, like an exhaust, turbos, air intakes. If it makes noise or alters the carbon emissions it's essentially illegal until you prove it's not. Meaning it doesn't exceed noise limits or have worse carbon emissions. I'd say for hoses if you replace them same same it doesn't matter what material they are or what brand you use. Same for nuts and bolts usually, they won't go and specifically check that your water hoses and some bolts are 100% OEM parts, that is nonsense.
