Yeah you're right Scotty. Double checked my figures today, and the injectors are maxing out. The FPR will get me out of the shit short term but I'll be getting it tuned shortly. You get the email from the HKS guys about the tune?

No mate, no emails about the HKS...

So Cihan should disclose all his tuning secrets so other tuners can copy his work? It won't happen... Too much time has been invested by him into the VQ25det now to just give the information away, I think my car has over 200 dyno runs on it already...

Not far to drive over Ryan for peace of mind...

Its not, but it becomes a pain in the arse to go back and forth every time I need a tune. Would rather work with someone local who is good and is interested in spending the time. There are a couple who have expressed interest, one with their own dyno.

It's interesting how this happens; your guy (and you) had to go through the learning process, and now there is more demand; the guys who put it in the "too hard basket" suddenly need a hand.

I don't doubt you have plenty of your own cash tied up in the entire process Scotty; no way 200+ dyno runs is a cheap process.

If your guy is good and interested; that is the ideal combination!

Maybe it would be worthwhile him investing his time and effort, so that he can hold himself up as one of only a small number of tuners that can work on the M35.

If you build it; they will come.

Exactly Dale, and that 200 runs isn't including the Emanage learning process before it.

I do honestly hope there are other tuning options and tuners in the future for the VQ25det, and if the guys at Nistune finally get on board we will all benefit. The HKS software is the best option available to us at the moment but there are so many things I would like to adjust that it doesn't have the maps for...

Agreed. Surely if your tuner is interested and is competent he doesn't need his hands held by someone that's done all the work...

Not for free anyway!

My tuner doesn't Jethro, it's the HKS guys who needed more information. The information they needed I don't think we could get from Scotty's tune anyway, as he's running non standard injectors.

Andrew now has these for sale on his web site: http://amperformance.com.au/product/miscellaneous/nissan-m35-stagea-performance-cold-air-intake-pipe

I will hopefully have a group buy price shortly for all those people who've contacted me.

So after installing, good increase in response and power.

Need less throttle to get the car rolling and coasting on legal speeds.

Car seems to have more rasp in exhaust note and engine feels slightly less smooth in the rev range.

Does this sound normal ?

cheers

Wow what a difference the intake makes on stock tune.

I've put the power duct cover back on and blocked half the stock snorkel to reduce airflow until my tune.

Back to normal, engine smooth, better idle and less noisy.

How's that for home tuning !

Block off the f**king intake...

So is it possible this intake could cause the ECU to change timing ?

It feels like a late spark or something.

Still surprised I have rough idle and engine rev.

Blocking off power duct has helped a little but not much.

Just had another thought.

Maybe air is coming in through the join, which is after the AFM.

There's no physical seal on these,just metal to metal.

Gonna try and get a clamp around it.

A clamp probably won't help; but a solid application of tape around the join will tell you if you're on the right track.

  • 1 month later...

Yep these intakes DO leak between the middle join.

When it's fitted the two halves are pulled out a fair bit stretching the spring.

After doing a smoke test, it was visible.

So had it removed and sealed with silicone.

    • Yes to both! Yes to standard ECU and tune, but exhaust is aftermarket. Unsure on brand. Actually have it sitting in at my desk haha! I have to set it up on my laptop but this is a great next step, will do. So I generally try to shift before 4.5K RPM most times. I largely don't do a lot of high-rev driving, but I will take it up to red 1-2x a week max, as I know the occasional "Italian tune-up" is good for these cars.  Oh wow, is this way better than what I'm getting. Does this mean there's a good chance I have an issue?   Thanks for all the info so far guys.
    • Old Son, did you re-use the Holden ABS in the new shell or try a different module?
    • Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.
    • Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up
    • Does anyone know ow what these two plugs are for and if they should be unplugged? Just put the dash back together and can't remember if these were plugged in before or unplugged! (Blue and white plugs) 🤦🏽‍♂️
