Edit Facts And Figures

[ms700]

Anyone ever watch drag video's of Jap cars (GTR's, Supra's etc) and notice the black weed pissing out of the exhaust when they're flying down the track running hi 9's / low 10's. Bet ya there definition of 'safe' AFR's aren't mid - low 12's. Rather mid 10's - low 11's.

<{POST_SNAPBACK}>

I dont think you could compare us with Japan accurately, especially cause those lucky pricks have ready access to 102 Octane up fuel!

Here is my 1.8c on the whole injector duty cycle/edit.

My car currently has :APS exhaust, Typhoon cooler, 10psi edit map, gapped plugs and GT/XR8 air intake. that's it. No custom tune. I had it on Sprio's dyno, so he could double check all my AFR's, boost levels, etc while he fitted my trans cooler. I regulary got 235RWKW and my injectors would be extremely close to 100% duty cycle, as the AFR's raised after 5000rpm. Spiro highly recommended to me that I get a custom tune done, along with some bigger injectors.

Id be guessing a safe AFR is nothing over 12:1. But im no tuner, im only a keyboard warrior!

might see a Unichip up for sale soon eh Bugster?..............!

My advice - don't be too hasty there is more water to travel under this ol bridge before all is revealed and understood.

Nah, no worries there mate. Believe it or not, I'm a very patient little fella and tend to do my research and make up my mind before committing to anything. Hell, to get the rims I want, I've been waiting two months so far, and still counting!

I'm satisfied that the Unichip will suit my needs, I don't need the latest and greatest. I'm not after as much power as I can possibly get - even if I could get an extra, say, 20rwkw with Edit, I'd still stick with my Unichip I reckon. Take my bike, for example. It's got a Power Commander on it (similar I guess to a Unichip) and makes about 126hp at the rear wheel. That's well up on stock, of course, but if I was after ultimate power, I'd just go out and buy something like a ZX10 which has around 180hp out of the box - imagine what that'd be like with similar mods!!

I'd just be happy with a car that was reasonably quick, a little different to most of the other T's out there, made me proud to own it and was fun to drive. And I think I'm well on my way to achieving that!

I don't see your name down on shockwavexr6t's 968 group buy list mate. Yet?!

I am looking to add to the "Edit Facts and Figures" with what could be a VERY common scenario because there are quite a few APS Phase II's out there.

So tomorrow, I will be taking my APS Phase II down to C&V. They will drop in a sweet intercooler, take out the Unichip and custom tune the Edit on the 968 injectors. I will get some before and after runs for comparison. From anecdotal evidence, the low-mid range is fat with a strong torque curve on boost levels not any higher than current Unichip-controlled levels. Apparently they have done quite a few of these APS Phase II to drop-in-a-bigger-intercooler Edit conversions successfully.

I am not after a screaming top-end power figure, though anything about 300rwkw appears achievable and eminently sensible in not pushing the envelope of reliability too high on stock internals etc. So consistent fat low-down urge from a bigger intercooler with boost coming on in a controlled manner on lighter throttle applications as well as more spirited squirts etc is what I have been promised.

Dont get me wrong, the strap-on was fun, but I will not be surprised to see some drift in the power/torque curves tomorrow because it feels down in power, particularly at lower levels, not to mention that Edit has already demonstrated to others like JB, Pashen etc to remove surging, rough idling etc. I will give a comprehensive report on my experience, and for those in the Sydney area, the best way to check it out is PM me for a test drive.

Safe and happy driving...Dr Z.

Dr Z look forward to your report. Just need to get the complimentary 3000k service out of the road for a warranty item , ie split seam on LH visor , and the Phoon will be there as well it appears. Phase 2 kit from WhiteTee with edit should be a nice little package

Got me some of Eugene's finest!

They will do the job adequately for the time being.....

Ah, silly me, I should have known!!

So in summary the max power with Edit alone debate remains unresolved. Somewhere between 220RWKW and 270RWKW depending on a range of factors, many of which a mystery. Why is this so hard? For a while we had some worthwhile debate but never got to the root question. Whatever peoples' opinions 278 RWKW with safe AFRs, safe boost levels, steady idle, smooth power curve and repeatable performance with no odd behaviour, HOWEVER IT IS ACHIEVED, sounds pretty darn good.

Your pretty right there mate, The fact of the matter is that if your talking edit alone, with nothing else, it would be hard to go much further than 250rwkw.

Its the hardware of the car that lets the software capabilities down anywhere after that. But I think the main feature of the question you were asking here is what is the best value performance mod for anyone starting out, and I think the answer has been shown many times in many threads.

It just so happens its not only the best mod for its money, but its helping out very heavily modified turbos that have been running for several years, with excellent gains on top of their already excellent results.

But like any tuning tool, Its the tuner that produces the results.

[dingah2]

Dingah.

......also with Edit you are even more reliant upon the integrity and inteligence of the tuner as there are more parameters that can be varied and no 'administrative restrictions' as to how far they can go to remain within (APS) manufacturers limits.

Beers cold, where are you young Danno...?
