How's about supporting closed loop and lean protection from widebands connected via the V3 Analog Inputs connector? That input is much cleaner than the existing options, as there is no concern for cutting out resistors, checking for capacitor presence and the like with the existing original four choices on the main ECU connectors. Plus, the ECU ground plane is also easily available right there.

Selfishly, I'll admit to having wired mine that way initially, thinking closed loop was supported. Sensor logged & displayed perfectly...but no closed loop. Ooops.

These tables start populating with data right when you connect to the ECU, even without datalogging. This is very helpful for making quick changes after a pull, but I haven't found a way to reset or clear the tables without fully closing SManager and re-opening it. It would be helpful to be able to clear the tables after a pull to re-start the data collection and averaging, and not have the old data from the previous pull averaged in after making a change.

I have had the same problem, well its not really a problem but it could be easier for us to street tune for sure, the way i found to do it without smanager shutting down and popping error is ;

0.0 - start datalog/recording

1- do the passs you wanna do.

2- Park the car leave it run.

3- Unlog and stop recoding (F10 or F9)

4- while you car still run , neutral position and parking brake on do your modification to your calibration.

5- save the calibration (ctrl+s)

6- go to the graph section, close em all

7- upload new calibration (ctrl+u)

7-relog/start recording (F10 or F9)

8- just to make sur everything is fine i go back to the display section and give some gaz pedal kick to see tps% moving (0-100%)
If the TPS is getting data your good to go.

Hope it helps u mate!

Scenario 1:
With key on (either engine not running or already running...doesn't matter), If I then plug in my laptop with SManager open, no issues with how the car runs, and I can connect and datalog and upload a tune.

Scenario 2:
Laptop already plugged into the ECU with SManager running, then I turn the key on, often times I think it corrupts the tune loaded in the S300. I get a very poor idle (if it will run at all). Once I key off, disconnect laptop, key on, then reconnect laptop, I can re-upload the tune and it cranks and starts fine.

This mainly becomes a problem in the staging lanes. I like to leave my laptop plugged in with SManager running so that I can datalog directly to the laptop during the pass. However, if the staging lanes are backed up, I won't run my car to prevent heat soak, and I'll only crank it to pull forward. For now, I have to remember to disconnect my laptop each time before cranking, then plug it back in...it's kind of a hassle. Even worse, if I forget, my car may not start in the staging lanes until I go through the routine. Even worse than that, if I stall the car in the burnout box, it's a whole process to disconnect laptop, crank, reconnect laptop, click a few buttons, etc.

If you could make it where it doesn't need to be plugged in after the key is on, that would be very helpful.

Me and my teamate havr had a lot of issues like this, with internet connected to the laptop it resolve this, soo share the LtE from your phone to your laptop might help u on this one,
Send news soo we can evolve all togethers! Cheers mate

Appreciate the feedback - I'll try closing the graphs. But if Hondata is reading this - I think it'd be much neater to have a button to click to quickly and easily clear the lambda tables.

My problem is most of the tracks I go to do not have an internet signal I can connect my laptop to, and my phone is not a hot spot. Some of these tracks are out in the middle of nowhere, so sometimes even getting a cell phone signal can be questionable. We will see how it does when I go to the track in a couple of weeks.

Even better if we could have closed loop off of the digital input, then we don’t have to worry about ground offsets and analog issues at all.

I suspect this is a hardware limitation or we’d already have it, as KPro does.

Ctrl+L has always cleared logged values from the tables, unless I've misunderstood your description.

I also occasionally get frustrated with your other issue though - it catches me when I least expect it.

Thanks - I'll give that a shot and see if it works for me.

I'd like to start out by saying that I'm a software engineer with almost 20 years experience. So I may be a bit biased when I look at a piece of software like Hondata Smanager and think about the improvements that could be made.

Basically what got me on here posting is that I'd like to be able to run closed loop all the time (i.e. have the ecu able to adjust the air fuel ratio while WOT), but I can't seem to get the rate of change to work that great (or maybe how I envision it working/as well as I'd like it to work).

I came up with the concept of setting it up to only be able to add fuel but not remove any above a certain RPM, since I don't want it to accidentally go lean at WOT due to the closed loop swinging the afr with a negative value with the rate of change settings being kind of wonky (I can get it pretty close by lowering the numbers down and it will stay within 14.4-14.9 cruising for example but then it also adjusts really slowly).

I know I can accomplish (kind of) the same thing by setting the minimum short term adjustment to 0 (so it can't remove any fuel), but that will also mean it can't remove fuel when I'm *not* WOT so I will basically just lose out on fuel efficiency when cruising around. Either that or I would essentially have to tune the maps either just slightly rich or spot on so that way it only ever *needs* to add fuel, but even then I would probably end up erring on the side of rich and probably be cruising at like 14.5 which isn't the end of the world BUT I think it would be easy enough to add RPM based closed loop min/max adjustment. It would stop me from having to perfectly tune the entire table (which is going to take a long time due to not having a dyno and being able to hold constant rpm to target each cell and get it dialed in). I think eventually I could maybe get there but it will probably take me months to years to really get the whole thing perfect to where I could set it to never remove any fuel.

I'm thinking it would basically be easier to just have two RPM based tables (similar to the rate of change tables/max TPS tables):

Minimum short term adjustment:
Under 1000, 1000-2500, 2500-4000, over 4000 rpm
-15, -15, -15, 0

Maximum short term adjustment
Under 1000, 1000-2500, 2500-4000, over 4000 rpm
47,47,47,47

That way you can set the min/max based on the engine speed, so that under 4k rpm it can both subtract and add (based on the min/max you want) and then over 4k I can set the min to 0 so it can't remove any fuel (only add if it goes lean). Obviously this is just an example, I would really like it if it was just a 4 or 5 cell table and I could edit the RPM range values on the top row and the minimum/maximum trim values on the bottom row, similar to the 'Max TPS' tables and then just have it interpolate between them and set it to what I want.

This combined with the rate of change table would allow me to feel more comfortable using closed loop at higher rpm knowing it isn't going to remove fuel on me and cause it to go lean while also still having it set up to be able to correct quickly.

I think the obvious choice is to just "go to open loop and tune it to the correct afr" but I don't really want to always have to monitor/adjust the tune, I should be able to get it close/spot on and then set closed loop and forget about it and not have to worry about running lean randomly or constantly adjusting the tune based on a bunch of external factors (humidity, elevation, crappy pump gas, fuel tank pressure, etc.). I just feel like it could work a lot better than it currently does with this change.

Anyway this was kind of a long post, the only other thing I wanted to ask about was it seems the maximum closed loop RPM is stuck at 8k, does a value of 8k for the 'Maximum engine speed' value disable open loop? Or will it go into open loop above 8k, since I can't set it higher (or is there another setting I'm missing that will allow me to raise the max engine speed value?).

Thanks for taking the time to read this whole thing and I appreciate you guys over at Hondata, I just wish it was open source so I could just make the changes myself (honestly like I mentioned I'm a software engineer and if you sent me the code I would be willing to implement it and give the update to you guys for free ... not that I expect you to do that but just throwing it out there). It's possible other people would also get use out of this feature, I've seen a couple different threads online talking about running closed loop 100% of the time.

Anyway let me know your thoughts if this is something that could happen, also let me know about the 8k engine speed thing, not sure if I can raise that somehow since I'm spinning to 8.2k or if I should just lower my rev limiter to 8k so I don't go out of closed loop.

Also, would setting the 'fast - lean to rich' (or 'fast - rich to lean', can't remember which) setting to 0 above 4k stop it from removing fuel? I wouldn't think so since I would still have to have the 'slow' setting above 0 ... just a thought, let me know.

@spunkster @hondata you can delete my other post, I didn't realize there was a spot for suggesting/requesting these types of changes, I see that now which is why I'm posting here.

This is kind of what I'm envisioning as far as being able to change the min/max adjustment based on RPM (so you can have more control over closed loop adding/removing fuel at higher rpms and the ability to limit the amount it can remove/add).

I would like to have to same calibration lock/protection fonction as the Flashpro. So tables cannot be alter or seen... Can this be added to the S300 features?

Thanks and have a nice day!

Is it possible to implent a 3D Map for Dead Time and Fuel Pressure, like the one in Haltech (see in the Picture)?

Request for a keyboard shortcut to auto select the cells being logged in both SManager and KManager softwares.


Background:
I have created a device using an Arduino that reads the torque output voltage from the Mustang dyno I use, and subsequently changes the fuel/ignition timing accordingly to reach MBT, ONLY when I press and hold a button.

This device outputs keystrokes via USB to complete a couple of tasks.
First task: Select the cells that are currently being logged. Example Ctrl+Space
Second task: Increase / Decrease the ignition timing (based on the torque voltage output) using Ctrl+Up / Ctrl+Down etc.

I have tested this device in OBD1 tuning software which DOES have the ability to select the cells being logged, and the results were fantastic. I'm really happy with it. In both a slow load sweep at sustained RPM, and at road load in sustained RPM, the torque optimization gain was clear.

I would like to be able to do this with Hondata software too.

I am trying to set my 2-step launch control rpm higher than the FTS rpm and i cant do it. My launch rpm must always be lower than my FTS rpm in order to have both working. So what i want to end up running is the following:

Launch rpm: 7,600 rpms
VSS Disable: 4 MPH

FTS RPM: 7,200 rpms
Active After VSS: 10MPH

Before what i would have to do is wire a push button switch in series with the clutch pedal switch and taping it to my e-brake. pressing the button will disable the signal to the ECU FTS input (power steering ecu wire) which will allow me to hit my higher 2-step rpm with clutch pushed in. Releasing the button will allow me to have FTW once again.

This seems like a simple script to write... hopefully in the next update you guys can implement it.

Hopefully you're still active on here, I'm trying to set up just regular 2step and was hoping you could give me some more insight on how to wire a two-step activation switch, to my clutch safety switch. Just as a heads up, I'm not running power steering so what exactly do I need to splice into and from where to make the clutch safety switch activate the power steering wire, thus enabling two step
