@Angelo s38: just to make sure, you mean the socket g18 "power+12v" ??

And i checked it just now there is 12.7 V on the emu. So the emu device is powered. And i tried with a different computer with windows xp, same problem. The computer doesn't even recognize that the usb is plugged in. But i tried several drivers. I am not sure if it is a driver issue or anything else. Anyone an idea what can cause that problem?

[Angelo S38]

Yep G18 and G17 should be connected the device isn't powered by the usb port.

[semme]

It's all connected. i try win7 and a other usb cable next weekend, maybe the usb cable isn't working properly.

[Jadzwin]

Has your PC standard usb socket or mini usb (then you need OTG adapter).

[semme]

Hey, no it's a standard usb-a socket, and the usb socket of my computer is working, i checked it with other usb devices like iphone...

I have had this problem with weak Wifi, or no wifi signal to laptop. I know you loaded drivers manually, but usually I also need wifi enabled to make 1st connection to an EMU. Sometimes it takes a few min. for the laptop to find and load drivers for the individual EMU. Either that or no power or ground to EMU, you have power, what about ground to B17.

[semme]

Hey, all the Power grounds are connected to one point at the cylinder head (B24, G24, G17). All other Grounds are connected to one point at the chassis (B17, B18, and some ground connections coming directly from the sensors).
But that with the Wifi enabled is an interesting point. I will check this out tomorrow. And i rode through this thread and found out that i should run my computer only on battery, not connected to the power socket due to ground problems. And i rode also that it may be better to start the client as admin.

Anyway, the 2 sockets that have been delivered with the emu (The Black and Grey one) they are marked with numbers from A1-A8; B1-B8; C1-C8. Not with 1-24. Is this only at mine or do other people have the same Sockets. A1 should be "1" and C8 should be "24" i reckon? Is that right? Because i have connected the cables with this scheme.
Thanks a lot guys

Forget the numbers on the plugs, they are oem for these AMP sealed plugs, always use the card that came with the ecu.

I've been trying to use auto tune in 1.51, but two issues I am having.

1) On the proposed VE table it doesn't show any updates until I close the table and open it back up. Also, when I go to save (S) it doesn't change the Proposed map. For example, if a single cell shows 38.5, and the proposed table says it needs to be 45.5 if I save that one cell, it shows in the VE table. Then lets say I go to smooth out the VE table, to 51.0, if I go back to auto tune (close the window, and open it back up) it still shows the original value in the proposed VE table of the 45.5

2) I wish there was a way to get autotune closer to megasquirt autotune. It constantly applies the changes, and when it's done you just click apply and it's done. Anyway of getting autotune function like that?

Hi all, I have some feature requests.

1. Is it possible to add 2D map of O2 sensor delay (rpm vs. time delay)? I have O2 sensor about 1,5m from engine head (it is not possible to move it closer and read all 4 cylinders), and when i want to use autotune on rpm near idle, it changes bad cells - because it takes some time for exhaust gases to reach the sensor in these low rpm. For example, 800rpm/45KPa. If i press accelerator, i got 1200rpm/40KPa. After a second, or even later, it recognize lean mixture and change cell. But cell 1200/40 which is actual, but has good value, and problematic value which generated this lean mixture is in cell somewhere between these two cells. So it would be great to make autotune to change cell which was actual defined time ego (for actual rpm).

2. If 1. were not possible, then i would like to have a chance to set transient delay value higher than 1000ms. It does not solve this problem in case of active idle control, but better than nothing.

3. Idle valve deltaDC enrichment would be great.

Hi guys, I have one feature request, as I will try to use water injection - controlled by the EMU. The now available secondary injection option assumes, that you want to inject gasoline...
Would it be possible to define that the secondary injected "fuel" does not affect the primary injected fuel and would only be a (Staged inj. split) table defined percentage of the primary injection time?
Or alternatively a simple 2d Table with primary Injectors pulsewidth vs. output pulsewidth?

Thanks in advance!

Kind regards Clem

@ Jonny T: I think that your transient delay is only a problem with ultra-low-exhaustflow conditions ... idle. I doubt you would get much usable data with longer delay times. And just to have it said, exhaust flow is also greatly dependent on Load, not only rpm.
Try to get the engine stable with idle control at some higher rpm, and then decrease rpm slowly. You may decrease your ignition values at these areas (build some kind of a ramp) and you will have success.

What about nitrous control? I haven't dived into it, but it seems like it would work.


I would for autotune to show the differences in the maps. Like for it to show how the numbers changed. For instance, if a cell is rich, and the EMU pulls fuel, I would like the number to be in red. And if it was lean and added fuel, the number would be blue. Would be really helpful if this was possible.

[RHD]

A feature that has a frequency that follows rpm and a DC that is a percentage of the injector PW is something i have been wanting too.

Nutritious control is only a basic on/off control and the water/meth injection would idealy follow the injectors. This is probably something for the general discussion section but i think using the user PWM table would be the closest solution, but it would require 3D tuning like a fuel table to get it scaled correctly.

Gear cut function
would it be possible to add a VSS enable to the gear cut table, at the moment i use an external gear controller to supply a variable time cut request to the EMU but i dont want the cut while changing from 1st to 2nd gear ( due to gearbox design)
At the moment i block the cut signal using a VSS scaled parameter output to a relay, but would like to simplify things and remove the relay if possible.

Thanks

To update the proposed VE just run autotune command again from Tools menu. If you have not cleared the log, it may just correct to the same values. S should change your active VE table, not the proposed table.

When you open the proposed VE, are you doing it through tools menu, or log menu? Log menu will just re-open, tools menu will recalculate based on current log. I just leave proposed ve table open, and re apply each log as I gather more data.

I have also found on my laptop, that the actual VE table will graphically show my autotuned values, but the EMU will still be running the "old" value. Simply clicking any cell in VE table and hitting + then - will "refresh" and it then run VE that is displayed.

[ihiryu]

I'm going through the menu.

I close the proposed VE (pVE), then go through the menu again, but it doesn't change graphically in the actual VE (aVE).

So what I do is, I close the pVE, then open it again via the menu, then I'll select all cells on the pVE, and then press S, for it to paste everything on the aVE.

It's just hard to do that when you're all alone lol. On MS, it will constantly make changes to the VE table, and will run those values. Once you're done doing your street driving, you can review the VE tables, and decide if you like what it's doing. It also shows you the differences of it going richer, or leaner by changing the color of the cells.

Also, I would like if you guys could add a MINImum CLT to the autotune as well too. That way I can start auto tune before I drive to work, and once it gets to operating temp, it'll automatically auto tune.

Is there an update in the works that will highlight the X and y axis points to show what the coordinates are when the cursor is on the map?

I find it hard to see what rpm and what map value I'm at on the axis at a quick glance.

Also, is there a way to. Relocate the y axis unit labels to the left side of the graph?

I too would love if we could move load to the left.

[Jadzwin]

I check if it could be easy done...

I add it for next version
