rob - when you just tested the sbec did the boot log file show the 0xff coming back, or was it like the log i posted from my smec?

vipernbox and motorhead53 - are you reading a smec or sbec?

I'll check later tonight...

I get that same error and my boot log file shows the same 0xff from my smec.

84Omni , post up your log file

To me, that looks like its not bootstrapping. Normal DRB coms always echo back the command.

**wowzer** · 10-06-2013, 08:53 PM

84omni , smec or sbec?

Rob, I assume the ftdi cables have the TTL inverted option set?

**84omni** · 10-06-2013, 08:54 PM

Its a SMEC and the fuel pump doesn't prime when I turn the key on so I assume its boot straping.

I am on SBEC... on one of Rob's modules I soldered to the board... So don't entirely rule out a screwup on my part... But I did double check with continuity test ect.. and all seems well.. and van will start..

Here is the cable I am using... I bought it some time ago... but out of the package for the first time on this project.

Yep, that's one of the series 1. They don't work with the SBEC correctly. Can you send it back to me? I'll exchange it for one of the latest ones...

**vipernbox** · 10-06-2013, 11:19 PM

Heck I can just buy a new one..... If this one works with a SMEC I can keep it for that... Or send it back if ya want it...... No big deal either way..

(don't see an option to purchase one on your site currently though)

As long as it still registers with the PC when you plug it in, then it should work with the SMEC still.

I took them down because I ran out of boards and had to order more. But, they'll be here on Wed now, so I'll put them back up. Actually, these will be 'Series 3' and I'll probably offer them for sale (optionally) without a cable for those that want to use their own cable.

**vipernbox** · 10-07-2013, 11:03 AM

Order up!

So I know this is long over due and 3+years later but life got in the way and I've finally got my car back on the road and would like to make my flashable smec work. I'm have the same issues as the previous posters were having. I'm wondering if any of them have found a fix for it.

Check out the MPTune and MPScan sticky threads, the first posts for setup. Try that and see if it can get you up and running as far as cable communication.

Some have been late to the party, so you could look through the last few pages in those threads to see if you can find the latest help tidbits.

Then let us know what you encounter and we can try to help.

I went through that process and it looks as though everything checks out. I will check it again and take a screen shot and post the pics and let you all see if I'm missing anything. I also have screen shots of the prompts that come up when it fails to connect that I can post. also the cord I bought from boost button has a red wire that comes from the board that doesn't go anywhere, any idea what that's all about?

If you are using on a smec, disregard that pigtail wire. That is for SBEC.
You said you have a flashable SMEC, right? You do need to add a wire in your ecu harness for the bootstrap signal. Did you see that in the setup instructions.

What operating system on your pc? I've got mine working with Win10, and have used Win7 and XP.
With the proper drivers, it should find your cable.

**wowzer** · 06-14-2017, 10:08 AM

-make sure you have followed the directions to make sure the ftdi cable rx/tx signals are set up to be inverted.
-allow mptune to auto update so you know you are working with the latest version
-confirm that your com port is set up correctly and recognized by mptune. it should show the connection on the status bar at the bottom left of the window.
-if you still have problems post up the mpt2coms.txt file located in the mptune directory in your documents folder.

So 84omni is my brother and to fix his issue we had to click the LoadVCP box. If you go to the MPtune wiki under the Setup the USB to SCI cable and follow the directions:

Yes I bought the flashable SMEC and the FTDI cable from Boost Button back in 2012. I have the bootstrap hooked up as per Rob's directions directly to the battery ( I double checked it was in the correct location the other night )

I'm running Window's 10, I just went through the device manager and everything is up to date and it recognizes the cable.

Ok so I went through the instructions and checked everything, I think I have the setting right but I'll post the screen shots just in case I missed anything

these are the prompt messages I'm getting,

This is the log
