Hi Rick,
I agree - most of the gains I think are made by taking out some of the large safety margins Porsche thought necessary on the igntion timing side due to variability of fuel quality, tolerances etc.

Louie has already reported that when he remapped an '85 with the LH2.2 SharkTuner he found it pretty well fuelled.

So yes, gains to be made even on a stock 85/86. I am just at the point of trying the EZ-F SharkTuner on my own '86 Euro 16v :-) Just waitng for it to stop pissing with rain !

When I am happy that all is well with this version of the SharkTuner I will write the User Manual for EZ-F and then we are ready to go ! It works fine on the test bench.

We shall see what the costs are as we go along with this new project. There are all kinds of initial costs that contribute, even if the production run is 100 units. CAD for circuit boards, artworks, prototype boards components and so on. All these costs have to be recovered.

Setting up a key system may be possible, we could consider that. All takes time....time is precious.

I'll be happy to contribute Bill. If you send an early deposit, please let me know.

Hell, at that price point, I'm in and I don't even have the CAR yet, let alone the blower kit.

I have bought a LHD '88 928S4 - importing from Japan to Oz and sight unseen.

Yeah, yeah, I know: PPI, due diligence etc, but at around AUD$10K for the car (landed) when the parts alone are worth many times that here, it's a good risk.

So with the lowered cost of the unit, it seems more than likely a rental service would emerge at a reasonable cost.

RyanPerrella

honestly, i would hope the rental service would be non existant at this price. You would have n real need to tune the car unless you previously popped for a 7K boost setup, i think those doing this would just buy the ST.

John is trying to get it to the point that you buy it as opposed to just rent it.

Brian,
I got a call from a liquidator a few days ago. They've got a new (leased) dyno on a trailer that the leasee turned in. 503-399-1958. Dyno is located in Texas.

No affiliation, etc.

A dyno is a must have for tuning. The only reason I got mine was so I wouldn't kill myself or someone else tuning on the road. Plus, it's the only way to tell if tuning affected power +/- by a small amount.

Don't all get carried away - there isn't going to be a 950USD SharkTuner in the near future, maybe never.

The idea of this thread was to get some idea of the market demand at 950USD compared to demand at current prices.

Now we know that many private owners (rather than kit developers, etc.) would consider purchasing a ST at a lower price, that is a good incentive for us to do some serious investigation.

Once we know we can produce some at or near that target price, we will publish a specification, and invite deposits against a production volume run. If we don't get sufficient initial take up, then we will either return deposits or have to offer the new unit at a somewhat higher price to reflect increased costs due to reduced volume.

Time will tell...

Porsche always leaves a lot on the table from the factory. The stock fuel maps are very conservative. Thus, I think even a stock 928 could benefit from an ST. I've only done exhaust mods at this point (headers, Y pipe, free-flow 3.5" to the back with one borla) and ST tuning would definitely be a benefit for me. I do plan to turbo (not SC) this car in the next 5 years, though...

John Speake

Hi MIke
Yes, as soon as you liberate a stock 85/86 with just an exhaust modification then it is worth remapping.

Even a stock 85/86 will run much crisper after juist an LH tune. The standard EPROM has to be a compromise. One size doesn't fit all.... variations of cam timing, car to car and so on.

Huge bummer so .. back to rentals ...

RyanPerrella

yeah looks like it

back to andrews thread

As I said, not before next year, 6 months minimum. However we should be able to make proposals and initial pricings in a few months. Then things will be clear.

Don't jump to conclusions one way or the other.

In the meantime the existing SharkTuner will continue to be developed in response to customer fedback.

In other words... stay on the fence.

Hi Sterling,
One area is "metalwork". Punching slots and holes in plastic boxes. Cheap tooling charges and low per item cost is necessary.

The electronics stuff I can shop around here.

Thanks for your thoughts...

Ok Andrew,
You have a good weekend as well ... :-)

Never try to pin down an engineer to a timescale or result.....

Are you SharkTuning again this wekend ?
