Glad you got it working! You can configure the HC-06 module by sending it the correct AT commands - this is what we use in the RaceCapture/pro bluetooth module. We've never needed to toggle or pull-high a pin, at least not on the raw module. In any case, glad you got it working! Until I found the i...

SUCCESS!!! OK, I finally got it to work...but I don't like the answer. I could never get the MJ Config 4.0.2 to write to the chip. Nothing I changed seemed to solve it. I finally remember reading about PCJolt. I downloaded a new copy and ran it. Connecting to the MJ was easy via Bluetooth and I was ...

Thanks for the info...with that information I think I can see that the BT module works for displaying runtime information but not for communicating to write to the MJ. The delay I am seeing (around 35 seconds) before the connection is re-established must be a timeout and because the config didn't wr...

The icon is greyed out, which is why I overlooked it.

I believe I found the problem. Per the manual: Writing the Ignition Configuration After editing the ignition map or controller options, you may write the changes to the controller. To do this, click the Write Ignition Configuration toolbar icon Mjlj write config toolbar.png to send your changes to t...

I realized my last post was a bit muddled...it was very late! It appears that when power is lost the map is not retained correctly. I haven't yet verified with a serial cable if the initial connection being made could be what is causing the corruption or if it is really just the power loss. I am rea...

More updates: At some point my map is getting corrupted. It only appears to happen in conjunction with a power cycle...I have no way to determine if it is during the power being shut down and the power being restored. At some point the Loan Bins and the RPM buckets get set to values that are impossi...

Success!!!....Kind of...so close I can taste it... After getting the BT Module to be in 38,400 Baud and connecting to the MJ unit (jumper from 3rd pin in to RXT, jumper from 4th pin in to TXD, jumper from 2nd pin from MAP sensor to VCC, jumper from 3rd pin on MAP to GND) I was able to write my map, ...

Thanks...I figured it out before reading this, except the real time mode change, that would have helped...for my module I had to also solder in a pin at the Key terminal and pull it high to enter AT mode...I could get an OK but couldn't change the Baud rate without it. I was then able to attempt a r...

Brent -- I thought you said that the BT module had to be programmed from the wired side. Doesn't that unit just give your RS-232/RS-422 port a BT connection? I asked the same question and he told me this is to give a serial device (like the MJ) a BT conenction...similar to what we are trying with t...

I was able to change the baud rate of my BT module with the USB to serial adapter. It is absolutely necessary to use some sort of "batch" method of sending the data to the BT module since it doesn't wait for an enter command and only waits for around 500 msec. I used Tera Term and used th...

I have the same USB to Serial adapter. I was able, 1 time, to connect to the the MJ Lite and upload a curve. I have yet to get a BT connection to do anything but crash MJ Lite Configurator. I have no way to verify if the curve I uploaded is there, if the unit will function, etc. The BT modules work ...

Tried again last night. I had odd results when attempting to test the connection using Termite 2.9. According to the link above, I should get an "OK" back when sending an "AT". Instead I get [18][18]œœ[18][18]œœ99½½9...

There is some more info on this thread: http://www.autosportlabs.org/viewtopic.php?p=20971#20971 I think we are getting close. Most of the BT boards that are out there are defaulted to 9600 baud but it seems that the MJLJ board wants 38,400 baud. Just trying to get a decent way of configuring my BT...
