Logging wideband via serial cable, how?
Logging wideband via serial cable, how? i could use some help. I’ve been trying to put bits and pieces together on how to do this but I can’t get it working. I’ve akreasy toasted one wideband controller due to me trying to get this working. So here’s what I have.
Hp tuners
innovate lc2 4.9 dB series
serial cable
usb to serial adapter, not a cheap eBay one. Came from a local computer store and worked with another programmer I have. I’m also using a usb to micro USB adapter because I only have one full size usb. I may get a splitter and try that.
I added innovate eq ratio and afr to the serial channels. The icon shows up. Then when I start logging, it disappears. I tried messing with the rate on the transfer speed. Updating drivers. It’s on com port 8 and the computer is seeing the adapter. It says it’s working properly, but hp tuners isn’t picking it up. What am I missing? Thx

Did you install the software that should have been included with the serial cable? If not you must install the software or download and then install.
Try seeing if hyper terminal is reading the data. The OS on your laptop might not have hyper terminal. If so you have to download and install first.
If hyper terminal can interpret and display the data then back to your connections from wideband to the laptop, HP and serial cable software.
Are you absolutely sure your ground is good and/or tried switching to another good source?

Thanks. I didn’t download drivers for my adapter. It’s one I’ve had for a very long time. The drivers are on another laptop I no longer have. So I ordered a new one. I’d doesnt have any names on it so I’m not sure what it is. I’ll try that. Thanks for your reply.

You are on your own when downloading drivers if the cable didn't come with drivers.

Might be better buy a new cable with the correct drivers/software

As always - inspect the pins to make sure one or two aren't bent.

I forgot to install the drivers as well. I bought this adapter for 14 bucks and the drivers are linked on the purchase page

Note:
After getting everything to work and you are getting successful data transmission, note which USB port you are plugged into (if you device has more than one USB port).
Always use that same port when connecting again. DON'T use another USB port.
If you are having trouble getting a good read on initial setup - try another USB port until successful. Then always use that same USB port.
Same steps apply if you are connecting the cable to your device and it only has one USB port. If the single USB port is allocated to another device and you have to use it (a bluetooth mouse for example), Then you will have to to add a mini-USB hub or disconnect that device temporarily to use the single port.
Again, always plug your wide band serial to USB cable into the same port on the min-hub.

I found the drivers for my cable. ive tried two different computers. Both only have one usb but have micro usb. the computer recognizes when i plug into the full size usb but does not when i plug into the micro. I ordered a splitter and another usb to serial cable just in case.

Might want to cancel and contact Lorenz at LSX. Looks like he tested with many serial cables until finding one that works well.

i ordered one with an ftdi chip. Found a thread a guy posted a link to one he bought that worked with his so I bought that one. I refuse to spend $40 on a cable from innovate. I’d rather spend $100 on different cables to find one that works than to support robbery.
I feel like this is not that complicated lol. It should work with your current adapter. Did you have the correct comm port setup in the device manager settings? Usually this stuff is Comm 1. Also, from my last post....are you using a null modem? My stuff wont work without a null modem as the Tx/Rx pins needs to be swapped.
My problems are likely self inflicted. In a hurry. Not wanting to spend money. And tryout my yo use a win book micro tablet. It works just fine with hp tuners but it won’t work with my cortex boost controller. I may end up having to use my full size laptop. I don’t kniw what a null modem is.

It has to do with how serial communication is wired. There is a DTE and DCE and you need to have the pinout right so that one can talk to the other. Many pieces of equipment require swapping pins 2 and 3, which is transmit and receive, so that the transmit of 1 goes to the receive of the other......a null modem is just a cheap dumb inline DB9 adapter that swaps the pins for you.

I think I'm doing this correct, so maybe i'm just having issues with stubborn computers. I do have a full size laptop but i've been spoiled with these little micro devices ive been using that i just didnt wanna fool with the laptop. I'm gonna down load the drivers this evening and try it, i think it have like three usb ports. i've been using a little 7" windows tablet and then a little 9" rca convertible table to do my tuning. Having those super small units is very nice, but I just need to get this fuction working. Trying to watch a wideband and rpm at the same time is pretty much impossible and dangerous.
Ok my fellas. I got it working. I couldn’t get it to work on my mini windows tablet but it works on my small tablet/laptop. I picked up a usb hub from Walmart last night and my usb serial came in. I couldn’t get it to work until I tried the new serial adapter. Thanks for all your help. Now I have to figure out the best way to log afr. Doing it plotted against rpm just isn’t accurate enough.
Since I’ve changed it to plot rpm across the top and map kpa on the side. Like my ve map is. Maybe I can get better accuracy there. I did figure out that after 6000rpm afr started dropping like a rock starting out at 11.8 to 10.8 at 6900rpm. I’m thinking my air filter is choking the **** out of it because I have my fuel map leaning out pretty steeply after that. My air filter is a k&n rg-1002rd-l
its 6” at the base
4” inlet
4.75” at the top with an open end (filtered of course)
and the filter media is only 5.5” tall
i found a same filter but 9.5” tall which I’m about to order it.

It can be frustrating at times. Goes to show that there is a difference in the equipment we use - one device works the other does not.
Lorenz at LSX Power Tuning mentioned the same thing when trying different serial cables.
If you do drop a connection from time to time in a particular port, you have the option of testing the other two to see if one is better than the other. You might have to adjust baud rate too (9600 VS up to 115000). If the laptop is older, cleaning out old unused com port associations helps too. Think about all of the many devices you have connected and disconnected thru 3 USB ports.

Good to hear you got it working.

well last night I was plotting it against just rpm. At least to see if it works. And making a run, it sporadically had like a 16 or 18:1 thrown in the cell. But I think that’s when I let off and was coasting down.
