I couldn't have said it better myself!

DR

Nope, those are too small (tried them), the ones we use are larger and one of them makes 350 ft/lbs torque on a stock 5.4L engine (and we use 2 of those). They are also commonly available in larger bored out and/or custom made sizes so if anyone ever needs more CFM it is an easy upgrade.

Do you mean the Twinscrew or the SharkTuner?

DR

BOTH

Just lurking from the 993tt side to say...WOW!

So how many guys have you recruited to sit in the back hatch area when you run the
dyno, Andrew?
Not sure what's the optimum tire pressure for maximum dyno wheel adhesion.

Dave,
Time to install a dyno in your garage. You have just about everything else (including an oscilloscope - impressive). Maybe the next run they can calibrate it using RPMs on the x-axis instead of MPH. I'd rather not do the conversion - my head hurts.

DR

Dyno would be great, but would rather have a CNC machine and a waterjet at the moment!
Wouldn't want you to get a headache so here is a tuning run (obviously A/F not perfect yet) that is plotted in Engine RPMs. Run starts at approx 1500-1600rpm with over 300rwtq :-)

Flott Leben

Thanks, Dave. That is exactly what I wanted to see. Wow! Over 300 ft-lbs at 1600 rpms. Crazy stuff.

Here's a little tease....

Flott Leben

John,

Will the final Shark Tuner make the Spanner obsolete?

John Speake

No, the Spanner is much handier to keep in the glove compartment of the car, than a laptop based version.

The fault panel for EZK is essential because it is a waste of time remapping the igntion if there is a knock sensor or Hall problem. These faults are rather obscure....

.............and yes, I had noticed that this "car" in the screen shot is running at 3500rpm and 75% load while still in Park :-)

This is because unit is being driven by the test jig

Flott Leben

Other than size, are there any other advantages to the Spanner over the SharkTuner? Will the SharkTuner do everything the Spanner does?

Will the LH and EZK be packaged as one SharkTuner or be sold separately? I like the fault buttons on the EZK screen. Any chance of putting a similar feature on the LH screen as well (or are they already there and I just didn't notice them at DR's place)?

By the way, there were many impressed fans of the SharkTuner at SITM.

AO

I was one! That's for sure!

DR

It was also handy for finding a bad MAF, and a loose pin in the MAF extension cable on Sunday..... and on Monday it was handy to tell us the TPS switch had crapped out.

I have found the SharkTuner to be just as valuable as a troubleshooting tool as it is a tuning tool. But, unless I missed something (or John's holding out on me:-) the ST cannot read all the error codes and certainly can't clear them. That is where the Spanner or Hammer comes to play.
