hmm i dont like that little dib on the curve..

But still good figure none-the less..

What gear was that tune in?

wait is yours auto isnt it? how does the dyno reading work?

anyways where did you get your safc2 from?

Stupid apexi :P

im fairly certain its 1.1, its not harmful to the car is it?

0.8 are better.. 1.1 is too big..

I just changed the GTR ones last night.. wooo!

SAFC have aids and are so ghay to tune!

p.s your a/f are all over the place!

With regard to gaps, you go for the largest gap you can use without getting misfiring. Stock gap is 1.1mm but generally when you start upping the boost you need to drop the gap to about 0.8mm. If you have to go lower than that it's because your coilpacks aren't up to the job but in regards to your car Paul, if it's running fine now, great. Don't change anything. Equally don't be surprised if that misfiring comes back at some stage. It will be the coilpacks if it does.

I don't think the AFR's are too bad considering it's just an SAFC. You'll never get a flat line with that.

The dip in the curve is fairly typical of a stock ecu/fuel computer piggyback.

Guilt-Toy - Not denying that's a good tune but it's a happy dyno too.

Thats true, Thats what I don't like about the SAFC's you can never get them perfect..

And in regards to replacing coil packs, i won't have a problem with miss firing as the spark plugs are more than cable of running the car with the standard turbo.

I will only need to replace coil packs say if i do a high flow and start pushing for close to 300rwkw or so...

If u run the right plugs at the right gap, and the right sort of fuel, say good buy to miss firing!

Yeah, in optimum condition the standard coil packs are up to the task of working correctly with low/mild boost. Yours aren't in optimum condition though, they're more than likely 100,000+kms old. You will need to replace the coil packs WHEN (not if) they fail, regardless of whether you're pushing 200rwkw or 300rwkw.

The issue with setting your gap too small is that the spark duration will be very quick and the spark will be weaker. The consequence is high exhaust emission levels due to the mixture not being burned as completely as with a fatter hotter spark. It'll result in an increase in fuel consumption and potentially a minor decrease in power. Rather than 'curing' your misfiring at 1.1mm by gapping directly to 0.7, it's smart to decrease in increments of .1 until the problem goes away. Often tuners wont do this though as it can be time consuming. If you are confident with doing this yourself you may save yourself some petrol..

Exactly what promordial said.. i seriously think gapped to 0.7 is way too much..

Refer to the thread ages ago about plugs. There was a huge debate about it. Someone dig that thread up lol..

so anyone keen on explaining that graph to me..

Or is all the power coming on after 80kms?

lol= no idea with this graph!!

cheers..

Hey homo-spec lol...

My boot is still going to look better than yours at S'n'S

Sif Doof is HOMO Spec :blush:

What are you putting in the boot ?

yeah probably... i dunno if mine is gunna be done by then...

What the...... I hope it will be :w00t:

Yeah I agree those AFR's are pretty good for a SAFC. its hard to get a SAFC to read that straight. If you changed that to lambda it would be much better to look at :blush:

The dyno is not as happy as some people think.. it read 100hp less compared to the auto salon dyno the next day. but every dyno is different.

Paul: Auto :):O:blush:

Graph looks good AFR wise and power I suppose.

Get new coils now! :) They make heap a difference.. Just ask Ed.. Bastard too my coils :w00t:

I miss my car :(

BTW Can I ask how much was the tune at C&V? How long did they take?

Oh and for dump and cat, just get them ones from Justjap. They work fine :)

Someone explain that graph to me dammit!!

Some tuners prefer to display the km/h on the bottom axis instead of RPM.. It looks like a 4th gear run judging by the speed. Why you would want to know power vs km/h i dont know? I would think power vs rpm would be much more useful. There's probably some reason why they would choose km/h instead of rpm, no idea what that is though? :thumbsup:

      Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.

      Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

      Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
