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.

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.

    • The SS button head cap screw on the back? If so, good to know. I presumed it was there for basic assembly and nothing more. 
    • Hello, everyone. I'm new to the forum. I have a 1989 Nissan Skyline R32 GTR. I have lost all power to the interior, including AC controls, the gauge cluster, turn signals, and windows. Stuff that still works includes the horn, brake lights, radio, and headlights. All fuses, in the interior and exterior boxes, tested good.  It starts and runs fine, just with no gauge power or anything stated above. No warning lights either. Things that I have tested: - Fusable link tested fine - No other fuses blown - Alternator good - IGN switch tested fine - With my power probe, I can backfeed power through the IGN pin to the plug on the back of the gauge cluster, and everything comes back on.    So my theory is something on the control side that sends the ignition power through the system isn't doing its job, or a wire is broken. (I would think that it is the ignition switch that would do that, but who knows?). The ignition relays don't fire (all relays tested good). So what tells them to fire other than the IGN switch?  I would really appreciate it if someone had some insight on this. I have tons of hours into this; I don't want to give up in defeat! I have the HD wiring diagram, but having all those wires laid out like that on one sheet of paper makes things pretty hard to follow.  Thanks for reading, and thanks for the replies.  Where should I look next? Thanks.
    • Install a MAP sensor pre and post throttle. Best data you could have for NA, then play with the bends and/or air box and see how much of inflection is created at WOT on the plot.
    • And gone to a new home  
    • The car remains in paint jail. I am now pretty convinced that the whole "RB25 Airboxes are kinda limiting to ~300kw" could be a thing. Also saw a good video from Engine Masters: (Sorry for FB link) (https://www.facebook.com/watch/?ref=search&v=761771519471924&external_log_id=c10bcbb6-2c39-4ff3-9240-287e9921fde6&q=Cold Air Considerations) Where they tested Pod Filter sizes and kept adding bends to a LS3 on an Engine Dyno to find if bends caused power loss. It's a good video worth watching - They did lose ~25hp from making an intake which had 3x90's and a 120 degree. They only lost maybe 1hp with a basic 90. I feel that by sealing up my airbox I have: 1) Created the same restriction a stock airbox would have. 2) Created a very convoluted set of intake 'pipes' by forcing all the air through the ducts. So I am pretty confident I'll be going full circle and have a huge hot air intake pod and actually see a benefit. The air does *not* stay hot once it gets flowing, aided by the ducts, and the pod can then pull air from anywhere. All the posts of yore talk about the stock airbox costing 10-15kw at 300kw+ but you know what? I f**king would very much like that 10-15kw and I remember my own pod filter in engine bay experiences. Turns out the GTT Reo and Headlight brackets really don't allow you to mount GTR items, no matter what the internet says. Various brackets have had to be made up to actually make it fit right for the front bar. Also some idiot mounted a 3L Accusump right where the bumper wants to go, so that has had to be 'relocated' To where, I am still not sure, but it's supposedly mounted in the pictures and I can't see it.
