I thought this might be the case, but if you are serious about tuning, then I think you should probably have a dedicated WBO2. But maybe that thought should be reevaluated. Too bad there isn't a tail-pip sniffer option for the WBO2. Does anyone know of such a thing?

I would say your typical session is at least 5 hours for both LH and EZ-K. If we throw in the installation time for a WB, add another hour minimum. The actual tuning time in the car for 90% of the tuning is about one hour for each LH and EZ-K. Then maybe another hour or so for fine tuning on the dyno.

I think you could probably tune 2... maybe 3 cars in one full weekend. More than that would be near impossible IMHO

I do not believe so...

John Speake

I tend to agree that a local group with some expertise within that group is probably the best safeguard against things going wrong, and also could circumvent the requirement for a large deposit.

If someone inexperienced rents a ST for just a few days on their own with no friendly backup then they may be too rushed and end up making mistakes.

Just fitting a WBO2 and setting it up can take a 1/2 day....

The other possibility is someone who " ..has SharkTuner, will travel..."

Personally, i don't want to get into renting SharkTuners myself. I have other things to do. Life is complicated enough already.

The SharkTuner was priced on an expected sales of a few 10's. Production is quite labour intensive, and the price also reflects the many hours we have spent developing the product, hardware and software. Yes, you can buy an aftermarket FI system, but it will take you many more hours to install and tune the system to run properly under all conditions.

With the SharkTuner you can Autotune the LH quickly, and tuning the EZK with a knowledgable passeneger can be done in a couple of hours, even on public roads. I 've tuned a supercharged GT on our crowded roads here in the UK.

Yes, the Innovate LC-1 has a tail pipe sniffer attachment, which I purchased, but have not tried at this point.

I ordered a second bung installed in the X-pipe Dave Lomas (Motorsport) produces. They sent the X-pipe with a blanking plug installed in one of the bungs. It came in very handy after screwing around forever with the LC-1's narrow-band emulator.

John i hear you on your investment on time and parts.

With all the people running Superchargers, strokers, and turbo's which is my current favorite way to go. I think there is a larger market there.

I know preselling 100x sharktuners would be difficult. But if you could get that many, would $1000 each be a price thats attainable.

I think i mentioned that I feel somewhat bad if you sell one sharktuner that 100 people end up using. That dosent justify your investment. Without you doing this on your own no such thing would exist. So I as well as many others are very thankful for it. But maybe with a large order and say a 3-4 month wait for them to be produced, could we reduce the price of the thing? Or is it really not an option. I realise 100 is quite a bit, but with people spending $20K for strokers $8K for superchargers, whats an extra grand. Again that may not be attainable. If not then i would probably buy one for the $2500 or whatever but if i did i would most likely seek renting it out to make back most if not all of my investment. Sure that is good for me, but it still only get you one sale when 10+ people use it.

See where i am coming from?

I took the original question to mean, "Do I need to have both the narrow band and WB installed at the same time?" I believe the SharkTuner does not use the factory O2 sensor when sharktuning - i.e. closed loop.

Will have to look into the tailpipe connection as that would be easiest for a lot of people.

Giovanni

How much does it cost to have a bung welded? $15-20? How much for the tailpipe connection? More stuff to loose or get damaged.

I think the bung would be the best option. Plug the new o2 sensor, unplug the car's o2 wires, hook up the ST and you are good to go. You can remove the car's o2 with the exhaust in place but its a B!TCH to remove.

dr bob

A "tailpipe connection" has some serious disadvantages. First and foremost, it won't work on a car with cats, period. Second, even if the cats are gone, the sensor relies on maintaining a certain temp to work. The electric heater helps but I suspect that it doesn't really make enough heat on its own. Third issue is the response time for changes up front to show up at the rear of the car. The reason that the original sensor is installed so close to the engine is to minimize process lags between adjustment and measured response. YMMV, of course.

Where is the option for "I'll buy one when an L-Jet version is available"?

All,
I have everything needed to so this, except I am using my work laptop for tuning. If I find a cheap laptop to use I may be able to rent the package. I am getting ready to tune my timing once the weather breaks, it has just been to damn hot.
Time to tune is at a minimum the weekend, just for fuel management. It is unrealistic to do multiple cars due to the installation time and amount of tuning per car. I like to drive for a good half day to get the autotune dialed in, then smooth out the mapping and adjust for cold starts. The second day I make a few pulls on the dyno to fine tune. Then you have to let everything cool down before uninstalling and burning the new chip. This all has to be done before you can think about changing the timing.
It is a long process, but well worth it.

Andrew - we are about at the same spot. My next step is to install my superMAF, wire up my water/methanolinjection and install my 10psi pulley. Then I have to retune the fuel and advance my timing. Sure wish I had time to do all of this. Anyone want to help?

Later, Woody

We have talked about a local "shark tuner" here in DFW and also renting one out on a case by case basis.
I am happy to buy one and under certain conditions rent it out with assistance.
I only wish I knew what it did and how to do it.
Way to go Andrew.

whitefox

I would rent, but giving the full price of the unit as a deposit is not within my budget.

John Speake

Dr Bob is exactly correct on the topic of tail pipe sensor placement.

Andrew, while you are actually SahrkTuning, the O2 loop is inhibited so that the SharkTuner can "take over control". For the other times when you are not acyaually Autotuning, the loop operates normally. In those cases you can either feed the simulated narrow band output from youjr LC-1 etc back into the cars 3 pin connector, or retain the standard NB sensor in a second bung on your X pipe. If you don't feed back any signal into the loop, the car will just run with default mid range settings. The advantage of having the NB signal is that you can quickly check all is well when the car runs with the new mappping in closed loop (i.e before you blow the new EPROM)

Ryan, yes I understand where you're coming from, and I appreciate your comments. I realise that a higher price means more sharing of the smaller number of ST in the field. But if the price was (say) 950USD for a LH2.3 & EZK version, would a large number of people buy ? Perhaps I should run a poll.....

I will certainly look at the feasibilty of a cost reduction vs quantity...

drnick

john, does the shark tuner show up fault codes as well? i cant remember..
