Please help me understand why VEAL won't make changes
 

I installed a secondhand Rev built MS2E on my NB1 over the weekend. After a few hiccups, I have it starting and idling (@ 1000rpm) very reliably - much to the thanks of ample spoon-feeding by mlev, who was the previous owner.

I drove the car a little more today, and I'm trying to use VEAL to do the heavy lifting with my tune. For the life of me, I cannot understand why it won't make any changes. I *think* it was updating when I took those first trips around the block, but honestly I was so overwhelmed I can't say for sure :noob:

Here is my VEAL screen, showing the filters (they are knocked back, still nothing): https://www.miataturbo.net/attachmen...1&d=1403059732

Right after the above driving session resulted in no autotuning, I dumped the log of the same session into MegaLogViewer and ran VE Analyze on it with the following results:

40 Changes! Obviously there is tuning to be done - what settings do I have that are keeping VEAL from making them on the fly?

I've messed with my EGO settings - it's remained active for my testing; first trying the defaults, and then Brain's settings I found in his DIYPNP Installation Instructions PDF. Tried both Simple and PID algorithms. I've calibrated my AEM UEGO to the AFR table, it seems to read within .1-.4 at all times, albeit slightly delayed. I'm hoping there is something very simple I've overlooked, so please let me know what it is and flame away.

I also had this on 2.0.8 TS with 3.3.0 firmware
It basically never made changes so I had to manually tune 😁

Thanks for the reply, but after paying $59.95 to specifically use this feature, that's not going to be an acceptable solution for me. I still think it's more likely that I'm screwing something up in my settings, not dealing with a software bug. Is this a known/common issue?

One thing I haven't tried yet was to get a Serial cable laptop and ditch the USB to serial adaptor cable. Maybe try that?!

Maybe try to look on the Megasquirt forums and if you get anywhere please report back

I had manymanymany problems with mine while using the USB connector. I switched to a serial cable and everything works beautifully now. It's cheap and worth a shot.

Just found this on the msextra forums, I'm at the office now so I can't check my Data Rate, but I'll give it a try over lunch.

Another poster said that VEAL would only make changes with EGO turned off... I'm pretty sure I read a post on here yesterday that said you need EGO turned on for VEAL to work properly. It would make sense to me that these settings are used by VEAL to preform the adjustment calculations. Can anyone provide clarification?

EGO should be turned off when tuning to keep them from fighting each other.

no.

I thought the newer updates to VEanalyze live took EGO and other enrichments into account, so you no longer had to disable them. Am I incorrect?

My data rate was set to 15 frames, tried 10 - still did the exact same thing. While VEAL is running it shows the little dot moving around and tracing the active cells, "Correcting Table" is blinking red in the right hand corner, Update Controller is checked... Everything looks like it's working, it's just not making any changes.

I have a hard time believing it's a connection issue, everything else seems to be working perfectly. If my laptop had a serial port I would definitely try that, but I really need to get this working with a USB connection. Any other ideas?

Try a better USB to Serial adapter

Try a PCMCIA to serial adapter

Borrow an old serial ported laptop

try uninstalling and reinstall the software, something may have corrupted in the install

Firmware or TS ?

TS. it's software.

Sup now bitches :party:

I'm going to have to buy my IT guy lunch, but this was a score. Core 2 duo, XP sp3, 4 gigs of ram, Upgraded to a SSD!?, and 9-pin serial in ;)

Winning.

I'm very curious to know if the serial cable fixes it or not. I had the issue and several others have had it recently as well. I know it fixed my issues, but I haven;t seen any others post if it fixed theirs or not.

This is good

We need to know!

So I haven't set up the new tuning laptop yet, but on my way home from the office VEAL starting working on my existing setup. :facepalm: I only did two things differently:

1) Before I started auto-tuning, I selected all the VE cells on the map on the VEAL tap, right clicked, and hit "Back to Original Value" I really doubt this did anything.

2) I used a different USB port on my laptop. I know I have tried this port before, with no results, so this doesn't make much sense.

This is definitely feeling like a bad install//bad data communication. I do a new install with the direct serial connection and report back if anything changes. By the way, VE Analyze Live is totally bitchin' and worth the price of admission. :party: The car is already running quite a bit better. Proof:

are you sure it just wasn't the CLT filter?

Pretty sure. I know at one point I removed all the filters just to see if it'd change anything and nothing happened.
