"Shift light" by gear. Be able to customize the rpm warning in dashboard by different gears.
I shift at different points in different gears, and my tach is WAY off, and seems to have a delay. This would help avoid the guessing game.

My preference for ffs setpoint by gear is not to just do it by gear ratios. If you keep the ffs rpm low and you're using it just to keep throttle open between shifts (like I do), doing it by gear ratio is useless. I shift too fast for it to drop to the ffs point, anyway.

If you're using it to keep turbo spooled between shifts, you want a higher rpm set point so you actually hit megaspool.

Either way, seems custom set points by gear>auto rpm by gear ratio.

Or do both. Not like you got other stuff to do...

I've made a custom high load tune with Lean Burn in high vacuum closed loop.

I'm unable to disable P2096, so my CEL is on whenever I cruise for a while.

Verification of what map is installed (which may be impossible on the ecu), or a history of map flashes.

You can't run lean at idle on these cars or it throws a code. I don't think I have that one disabled myself.

Auto MAP sensor scalars/offset by choosing MAP sensor part number. You already do it for logging, not sure why it isn't an option for tuning.

For tuning you need to fill in the MAP sensor scalars. They added this MAP sensor brand/part# thing just to make it easier for logging and they covered pretty much all the MAP sensors on the market.
The chances someone has a weird custom MAP sensor or some 5BAR for 1000HP are usually very low and if that happens you can simply switch to MAP voltage logging.

Yes, I understand that, and have it tuned with manual value entry. I'm suggesting auto scalar filling in the tune by selecting the sensor just as they have it for logging.

In my experience, VT has done everything they can to make this easier for the "average" person. The "average" person doesn't know what scalars to punch in for the tune. I just took them off the values for logging (and later verified with MSF/VT forum known numbers), but just selecting is obviously easier.

Well, if when it comes to logging I can understand the "average person" difficulties and aids, when it comes to tuning if the average person cannot fill in MAP scalars, can't do MAF cals, and so on then this person should reach out to a person who knows what to do, eventually a professional e-tuner.
It would be awesome if the inputs to the tune would be "I have a big turbo or not and if I do then which one + I have this intake + I have or not have forged internals + I have meth or not + I have this or that MAP + I have this exhaust and these intake/exhaust manifolds" and the tune to be automagically generated... but it simply can't be like that.

We have thought about adding that, but it did not make it into the current release due to the architectural and time constraints.
It would definitely be a little time saver for some people. Elaborating on this idea, presets could be useful for all sensor calibration tables (choose your intake and the MAF calibration is prefilled, choose your MAP sensor and scalars are filled in, etc.). For now you can look up the values for specific MAP sensors in the dashboard parameter configuration screen.

[Enki]

I kinda figured it was a time issue. There's, uh, slightly more important stuff to work on right now than quality of life things I'd imagine.

[xfeejayx]

Was randomly thinking about this a couple days ago. You can probably just put a manual switch/button in parallel to the normal clutch switch. Press button to trip switch, clutch physically stays connected, car thinks it isn't connected, should go into Megaspool.

@Steve@VersaTune; That seem plausible? I imagine it's just the one ground switch that VT is looking at since light clutching will do it.

[Steve@VersaTune]

If you trip the clutch switch and exceed the speed and APP thresholds you will go into no lift shift mode. If you trip the clutch switch with a parallel switch, it should work the same.

[xfeejayx]

Welp, there's your rolling antilag Enki. VT+two wires+a button.

so I know we are talking about a way to do Rollin anti-lag. but we are talking cutting and adding wires and what not. I want the feature added like talked about thru versatuner software. no cutting or adding and hoping you did it right... so when is it going to be implemented? kinda disappointed it wasn't in the new update released.. same with high speed logging. these were next on the list I thought???

[meicalnissyen]

This is on the display / graph side

when looking at logs, lets say cranking thru a MAF cal.
you have the various params at the left, but not all are visible at any one time each param has high low and if the graph has been left clickeda vertical gray line appears and it shows current.

on each side of the graph are sliders which highlight when the corresponding graph thread is highlighted.

Could those sliders have a tiny tickmark applied to show the "current " value.

that way the exact value for a param that is out of sight could be seen just by highlighting its graph thread

Could you elaborate? I went to the dashboard, opend a slot went to the MAP sensor voltage param ( didnt see another map related param)
right clicked left clicked, said open sesame, did not see the 2 scalars and offset anywhere

I missing something?

ah, makes sense in hindsight

a subsetting of IMAP

wish they'd change the high value to 300 though, so I could use Robs values for the 845 sensor without checking the unsafe values box

I've been using Rob's values with the unsafe values box with no issue.

Where there any differences in MAP value reporting compared to the values we have in tht upgraded MAP sensor thread?

[meicalnissyen]

Thanks for that, and appreciate

just hate to hit that cuz then anywhere in the tune I miss a decimal point.......

Cuz Rob is a genius, and, well.......

change the high value from 250, to 300, and (many testy comments deleted) we can all be happy

[mituc]

No, I meant if, say, with the old values 300kPa MAP was 295kPa MAP or 305 or whatever with the new ones, or something like that.

I used the 65.79/1/5.41 values with my 3BAR as long as I had it and everything worked as expected, so I was curious what actual differences the new value make in therms of boost reading.

@rfinkle2;

[Mazdazilla6]

I feel like I may have said this before but having a live trace option would be awesome to see what cells are being used on each table while the car is running.

Also being able to reference cells in a table depending on where your mouse is on a graph would be nice. Similar to this:

[Enki]

That would be very cool.

[Fstrnyou]

Ya. Somehow link up the dashboard with the tune tables.
Perhaps have a dashboard button of sorts on each table in the tune and it will monitor what's needed to highlight the appropriate cells in the table.

When tuning my buddies Honduh, it's live tuning. So you see what cells are beine used while driving around and can make adjustments without stopping to reflash. I know our ECU doesn't allow live tuning, but it's nice to see where we are landing on the map.

[xfeejayx]

FFS running with time delay rather than a set RPM, i.e., go into FFS timing and hold RPM X time after clutch engaged at WOT; cut fuel and ignition before that time has elapsed.
Not sure if even possible without a piggyback/wot box. This would be easier for the user, but I imagine harder to create for VT.

I'd still be happy with the gear specific (or speed based?) WOT RPM.

[Yamahafreak]

Don't remember if anyone asked this before, read through the topic a couple a days ago..

Is it possible to have a build in "turbo timer" so when you turn of the engine after a drive the ECU shuts down the engine after "xx" seconds.
Even better would be if you can say if engine has xxx temperature run the engine for 30 seconds, and if it is at xxx temperature run the engine for 60 seconds.

I hate it when I have to splice something aftermarket in my OEM wiring.
If possible it would be great!!

Thats not possible. The key cylinder is still mechanical, you turn the power off when you turn the key cylinder off.

[mituc]

The turbotimer it you. When you know you drove very hard then just drive normal for 2-3 minutes before stopping the car, or let it idle one more minute.

these modern turbos are cooled with both water and oil so they cool down pretty quickly and efficiently.

[Mazdazilla6]

@Steve@VersaTune; I was taking some logs last night and for the first time used the intake manifold absolute pressure pid. The log shows around 20psi and my boost gauge read similar so I'm thinking this is actually gauge pressure?

I'm running a 1bar wastegate spring so I'm confident my boost gauge is accurate.

I'll have to go double check tonight, but I think I remember seeing intake manifold absolute pressure being absolute, not (absolute - atmosphere).

[mituc]

intake manifold pressure it's the MAP and that is absolute.
Now with the later versions there's a boost pid which gives you the actual boost (MAP-BARO) and can also use the parameters already given for the MAP pid (can be customized based on the MAP sensor type).

So @Mazdazilla6, if your MAP was around 20PSI I'd rather look at the MAP sensor settings available on the Dashboard -> Manifold Absolute Pressure pid -> Customize.

[Fstrnyou]

Can the PIDs in the datalog be in the same order as the dashboard instead of alphabetical?

Dashboard layout vs PID list in datalog:
1st 2nd
3rd 4th
5th etc....

When I lay out my dashboard, I put the important stuff at the top. I would like the same thing when I review a datalog instead of having to reorganize EVERY sidebar before I can even begin.

[xfeejayx]

Post processing/analysis. Should just be able to click a button on VT and get a torque curve for given car inputs. No reason to have to export a file for ricer graphs.

That is a pretty complex task. VirtualDyno, Torque and other similar software reached their maturity in years of testing and data analysis. Some even did not.
Since this kind of software is there already I would not see a problem to have a predefined logging preset ready to import directly from, say, VirtualDyno. Well, that doesn't even have to be predefined since you can do it yourself, all you need is RPM, Speed, Boost/MAP, AFR and APP. Until then your load curve is your torque curve.

[Enki]

Personally, I prefer to look at logs in raw number form.

[xfeejayx]

The math behind it is simple, 20 minutes tops in excel. You know your Time between readings (which is all the resolution any software like VD has), you can pick up Speed, ask the user to put in weight(Mass) and tire size(Radius), (dV/dT)*M*R, add in some filtering, done. I completely understand implementation is more difficult than that with a GUI and all.

I'm not disputing the value of raw numbers, I'm just offering a feature that people seem to care about. Load curves also do not take spark advance into account, so they really can't be used to tune that.

I think I'm actually going to go do this in excel right now because VD is such a pita.

[Enki]

You also have to account for wind resistance...right?
