I have the best of both worlds then! And no silly stripes to go with it!

By the way- Boost is a steady 0.35BAR, or 5 PSI. I'm not using over 4000rpm, and I'm going to check the stock injector (320cc) duty cycle soon. Stock Computer is dumping a lot of fuel into it, fuel consumption is..... interesting. But over all, its totally drivable at the moment.

Interesting, but don't you mean 370cc?

I'm pretty sure that the VQ35de has the same sized injectors as VQ25det.

From recent testing at APS the stock VQ fuel injector flows 328 cc at 100% duty cycle at 43.5 psi fuel pressure, 376 cc at 100% duty cycle at 58 psi fuel pressure and 412 cc at 100% duty cycle at 72.5 psi fuel pressure.

They wouldn't bother with the ghey market....

HKS is to busy building stuff like this...

HKS R34 GT-R

Wonder where I can get some HKS Stripes...?ninja.gif

Lolz

Is that it?....taxicab chassis for the broz!

What about the gt500 stuff?

hmm... fair enough... quick check of FAST resulted in;

PM35 injector part number is 16600-CD70A and is used in Z33, J31, F50 etc. Basically everything that is running a VQ35de.

NM35 injector part number is 16600-AA500 and is used in F50 (VQ30det), R34 (RB25det) and Y61 (TB48de).

Now to back track and find where I thought/read that they used the same injectors wacko.gif

Trick for new players- do up your trans cooler clamps tight when they are nice and hot! whistling.gif

I played Hansel and Gretel all round Sydney with Matic J yesterday. Anyways, noticed a puddle in the garage this arvo, sorted it out. Thought it was engine oil to start with, glad it wasn't!

Now have a nice layer of underbody rust protection!

Exciting news!

UPREV have patched my ECU. It now appears on the webpage for supported vehicles. I received an email for Mark @ Abbey Motorsports in the UK telling me of the good news. I now have a tunable ECU map, a "back to stock" map.

Now I just have to pay up, refresh my licence arrangements, and I'll be tunable!

Bit of progress today.

A couple of days ago I re-flashed the ECU. Just with the stock values, but with the throttle restriction removed, Speed limited to 300km/hph34r.gif, and a little adjustment of the rev limit/fuel cut/ throttle cut. All went successfully.

I have been having a problem with the ECU learning some strange fuel settings on closed loop. Basically what was happening was that on closed loop, Bank 2 was running a lot richer than Bank 1. it was about 80%/120% ratio. It didn't occur when the ECU was just fresh, but when it had driven for ~150kms, and the ECU learnt it. At the time it was stock ecu, not re-flashed at all. When it went open loop, it was fine. It spat a U1000 error, which is CAN bus error. Now nothing is wrong with the CAN bus, but what triggers that code, is when the ECU doesn't receive data from the emissions diagnostics for more than 2 seconds. So I went searching today- first port of call the bank 2 wideband sensor. When I pulled it apart it seemed ok, but the little rubber thingo in there wasn't sitting quite right so I pushed it all the way to the bottom, cleaned the plugs out and reconnected it. Also found a nipple in the intake tubes wasn't tight, so tightened that up. Anyways, the problem is absent now, I haven't put that many kms on it yet since the last "clear learned fuel" but I am optimistic that it will stay away. Idle is nice and smooth now, and while there is a little inconsistency,its not much, and doesn't appear when the car is at cruise with light throttle.

I want to know that the problem is gone, before I proceed with 600cc Injectors and fuel pump and tuning, as that would just exasperate the issue.

Also wired up my boost gauge, so now I know wtf is going on at night too!

Thought my exhaust was quiet- so got one of those Apps that measure Db. Don't know how accurate they are, but hey.

Measured according to the testing procedures- Exhaust height, 45 degree angle, 500mm away from tips

Measured 90db @ 4000rpm.

Legal ! banana.gif

Ok, some pics.

Any questions, ask away-

This is the oil feed for the turbo- its a t piece off the oil pressure sender.

Craig has taken to writing HKS on various parts of my car- ie- the trans cooler bracket.tongue.gif

That HKS bracket is now worth huge dollars.thumbsup.gif

It might be worth tracking down some stainless cable ties, http://www.ebay.com.au/itm/20-STAINLESS-STEEL-THERMAL-CABLE-TIES-35-CM-EXTRACTORS-DUMP-PIPE-/220948422796?pt=AU_Car_Parts_Accessories&hash=item33718d608c#ht_500wt_1287 or tie wiring the heat shielding around the cables running near the exhaust housing and under the wastegate pipework. Once you get on the dyno; I don't think they'll last long.

Even if they don't melt, they'll go brittle and crack off in no time.

    • How do people sell and buy modified cars in Victoria? Because internet says you have to get a RWC every time the car is sold. In NSW the blue slip / full check is only required for cars that had their registration lapsed or are bought from interstate. The yearly pink slip / rego check just looks at tyres, lights, leaks and things like that. They tend to not care about modifications. So can buy a car that is modified as long as it was registered before modifications. And then keep driving it. With the lingering threat of getting defected and fu<ked at any time.
    • I think just better tyres, I'm just on Hankook RS-4 tyres at the moment, which aren't really meant for the track. Also, been mucking around with my suspension for sometime now and I'm really happy bow neutral it is. Car doesn't want to just oversteer or understeer like it did years ago.  Time to put on proper tyres one day and see what the shit box can do at SMSP, One Raceway and Luddenham again.
    • How much work to get you in the 55s? Or just more seat time?

    • It's not "interpreted as" it literally is no more than 1 mod to the intake system. The turbo is considered something that affects emissions. So this has 0.0% chance of passing it's current state. Sorry to be the bearer of bad news, but this would absolutely need thousands to get on the road. Perhaps the seller still has the stock bits, but god knows what state the OEM wiring is to run the ECU, whether an OEM cluster is still available, etc. Generally speaking, RWC testers in Victoria are more conservative than the rules actually are to boot, so even if the car will pass, they won't even want to look at it, nor consult the actual roadworthiness requirements. They will simply throw it in the too hard basket with a flavor of arrogance and move onto the next job, even if the mods you have meet the requirements of VSI14.
