We can see everything with DataMaster.  Why copy to another program?

[whittlebeast]

I never got O2 data off that bike.  Only VTune data.

Lots of thing have changed in the last 5 years.

Well go out and get some! You're wasting time posting! Lol

Critical information is hidden in TTS logs.  You need to open the logs in MLVHD to see the hidden info.

What specific hidden information available in Metalogs, not available in TTS logs, do you need to *properly tune a Harley?
Bob
*Properly... defined as smooth power throughout the rpm range, throttle responsive, little to no decel backfiring, starts well hot, doesn't ping, good fuel mileage, expected power for the build.

We can see only what is recorded in any format.  I don't know how other products do what, but I do understand 20 frames per second on a CAN bike. 14 on a 1850 vtune data bike. As for as I can tell with all the products I use. TTS is the only one that shows a concern toward this.

All boils down to the same thing.  We only know what we know by the data we collect.  If you think the data you collect at any crank position you collect it at is good to go. I'm sure it will run fine. I'm after better data.  Garbage in, garbage out.

All you need to do is look at the fields exposed by TTS in Data Master compared to the data exposed in a Power Vision.  You will find them.  Ion Sense, VENew, Long term and Short term fuel trims, MAP read one and two come to mind.  Some of this was first hidden in TTS when I came around in about 08.  It was real apparent when I started looking at Datamaster logs that data was being hidden.  Several of us knew how the basic underlying math had to work.

In the Megasquirt world, you can expose any and all fields that the code uses for internal calculations, provided you know what you are doing.  That was how the tooth logger and map logger came up a few weeks ago.  Someone started asking questions about starting and tuning one of these motors.

Hidden, or not collected?  How does long term fuel trims help map VE's?  Are these things not collected so other things can be collected faster?

Let's look at Spark Data for example.  It must have a lot if "hidden data"  OR it is just reporting the data we need when collecting it.  That's the problem with data collection. We can update warm up enrichment at 20 frames a second, or not collect it at all. Doesn't mean Steve is twisting his handlebar mustache, laughing wildly and hiding it from us.

Open a TTS vtune data log in MLVHD and all sorts of TTS hidden things show up.  Same thing in most of the logs.  The data is there but someone feels you should should not be looking at them.  I prefer to decide if I can use them to my advantage.  This is the big reason the guys over at the Sporty forum mostly use Power Vision.  A girl from down under is one of the best over there.

Guess I'll try again...come on Andy, try to answer the question of specifically what of the hidden information do you need to tune a bike properly?
I find the information tuners see and can alter takes care of the complete tuning process but always looking to learn.

Maybe asking this way...
What tables are you altering that separates your tunes from others?

[whittlebeast]

Simply ask your buddy Steve.  Apparently, he is the only person you believe.  You could call Fuel Moto.  They have a good handle on how this works.  It is all fairly basic.

So no answer except to call someone else to get the answer to the question I asked YOU?
What SERT; SEPST, D/L, or TTS hidden information is holding you back from properly tuning a bike?

I just use use MLV to view the data that is in the logs.  TTS elects to hide it from you.

OK, I'm the dumb cluck here. What is this MLVHA and where do you get it?

[FLTRI]

So you only view the "hidden" information, not change it?
