Thanks for the feedback from a lot of you. Dustin, Shiv, can you adress the section below? Any timeframe for a fix? Do we know what causes it?

Thanks,

I don't think this is something Shiv/Dustin fix, this would have to go back to the company "ChipTorque" in Australia that actually manufacturers and programs (coding) the Xede for Vishnu. Correct me if I'm wrong guys ...

 

We all work close together in designing and testing the firmware/software. There is a little glitch in v3 where the CAS signal is sometimes interupted when engine speed is below 200rpm (like while cranking). There is no harm in this, just a little annoyance in 1 out of 10 starts. Just keep it cranking a second longer than usual and the car should start without any problem. No need to step on the gas or any other form of carb trickery

While the Chiptorque boys are coding the next firware revision, Dustin and I are working on new XMAP3 features to take advantage of the high speed COMMS communication now active. We are already 75% done with a road dyno feature. And this will be extended into some form of auto-tuning and closed loop boost control.

Just a heads up on some of the stuff we are working on...

Cheers,
Shiv

 

Nice. I actually inquired about the possibility of automatic map generation the last time I talked to Rhys about the xede protocol.

If you were able to get wideband O2 readings in xmap, you could probably generate baseline maps without any human intervention. Now _that_ would lead to some really quick tuning sessions.

That's the idea. Plug in the XEDE and hit "tune". No more my flying around to do something that a nifty little computer program can do nearly as well

Shiv

 

Hey that's the way things are going right? Engine computers are only going to get smarter. Can you imagine what people would have said 25 years ago if someone suggested that "tuning" would become sitting in the passenger's seat with a laptop?

Think of it this way, there's value in staying ahead of the curve. If you get autotune features ready before most of the market, then you'll be able to get quality tunes done at what seems like lightning speed. Think of how many more customers you could see a day if you could just push a button and get really, really good baseline maps!

Oh, plan on coming to the midwest soon? The ground has finally EDIT: thawed. Promise!

Wouldn't that put the other tuners out of business?

 

Shiv was joking. It's going to be a long time before computers can troubleshoot better than people. That's what you really pay for in a tune anyway, a smart person who can get the best numbers and deal with problems as they occur. Questions like "how much timing can I run" -- that's what computers can do for you.

Its reasons like this that I keep my Xede around. I'm a sucker for cool toys

 

What's this?!?!?

 

Is Shiv trying out his photochopping skills? If there was somewhat of an "Auto Tune" how much of an extent would this thing tune?

 

It would be pretty tough to make a computer program do all of the tuning, from behind to end. However, we're working on a program to that would do maybe 75-80 of the tuning, leaving only the important decisions to be made by the user/tuner. Since v3 XEDEs are capable of reading knock level, torque output (on a flat road), air/fuel ratio, boost, etc,. it is possible to design a logic flow chart that would allow the XEDE to tune itself to a very large extent. I just dont want to be out of a job so I'll make sure the autotuning process involves at least one or two keystrokes from a human being

Shiv

 

Are you auto tuning A/F in absolute mode?

 

Nah.. that table represents air/fuel ratio. The auto tune ignition program is much more of a challenge

 

Damn it. I wasn't fast enough w/ my ninja edit.
