Default Reverant - MS2 DIYPNP - 99 Turbo - Basic Setup & Firmware Questions

Warning: I'm very new to MS and currently in over my head. I'm very much interested in doing this right but can't seem to get my bearings about me. Here's some background.

I bought a used MS2 DIYPNP (I'm told it came from this group buy back in 2010):
99-00, 01-05 and MSM Megasquirt MS2 DIYPNP "Enhanced" group buy

I don't think it matters at this stage, but I'm running stock ignition systems (except 32-2 trigger wheel), GM IAT, and MAP sensor. Also, the i turn the key to on, the fuel pump runs. I've sine removed the Fuel Pump relay.

Current Situation:
  • With MS installed in the car (coils unplugged), I cannot get TunerStudio to "Detect" the controller.
  • I have this issue when creating a new project or going to "Communication Settings" and testing the connection.
  • I tried two Serial-to-USB adapters: Insignia (Best buy) and Gigaware (RadioShack) and both have the same issues (I've also tried to detect the controller with the key in various positions). I've since returned the adapters and purchased the DIYAutoTune (will arrive next week).
  • I've tried installing/uninstalling both Serial's current drivers. I also tried installing the FTDI Drivers, and usb_drivers_Windows but still no luck. I also played around with
  • I've tried different ports, adjusting COM settings in TS and on my PC, and have adjusted my Baud to 115200.
  • All that said, my computer (Windows 10) does acknowledge the adapters.
(I haven't run PortChecker yet, but I plan to in the next 24 hours if it matters. I have run FTDI's COMPort_Assignment Utility to no avail. It doesn't see any FTDI devices).

Questions:
1. Assuming it's MS is built correctly, obviously one possibility is my Serial-to-USB isn't communicating properly (I don't know if either example above had a FTDI chip sets). But if that's not the case: are these symptoms of a MS that hasn't had its Firmware installed yet? What other items should I check?

2. Does anyone know if the MSs in group-buy linked to above came with Firmware installed?

3. To make my setup as clean as possible, my goal is to install the newest firmware, (MS2/Extra 3.4.2 release Firmware) and write a tune from scratch/research. I plan to run "ms2loader_win32.exe" contained in the firmware Zip file. If this is correct, do I still need to Jumper the MS if I'm only updating the firmware. Does the Reverant - MS2 DIYPNP run mspnp2.ini ?

4. I feel like there's a ton of documentation floating around. Much of it seems outdated, not applicable, or even redundant. Can anyone recommend the critical documents I should start reading, for having a pre-built DIYPNP? (NOTE: I know there're a stickies on Miataturbo.net) I've already read throughThanks in advance. I'm sure these questions have been answered before, but I'm really spinning my wheels here :-\. I (naively) pictured this step of my build to be about tuning, not ECU setup. I was spoiled with tuning my stock Evo IX I suppose :-\.

Not sure on the original group buy MS2 built by Reverant but the later MS2 units require specific firmware from him.

I wouldn't try to load anything from the DIY web site until I had confirmation from him.

Best to PM him Reverant or email him info@mslabs.gr (https://mslabs.gr/)

Thanks bahurd! Good to know about the potentially custom firmware. I'll reach out to him.

Additionally, I wonder if a running fuel pump is an indication of an active MS?

All our units always shipped with firmware and basemaps. If it runs the fuel pump for 2 secs with the ignition on, it has firmware. If you can't communicate with it, try a different USB to serial cable. If none work, try installing the 3.4.0 firmware using the boot jumper. Yes, this particular unit did have a modified firmware but at that point (2010) it was needed because the stock MS2 firmware didn't have A/C control. This particular unit can be reflashed with a newer firmware.

Awesome! I'll try the DIYAutotune USB to serial cable. Do you happen to have a recommend 99 Miata base/startup map for 3.4.0?

The DIYAutotune USB to serial finally arrived. Even with all the drivers seemingly properly installed, TunerStudio still refuses to acknowledge the MS Controller.

I'm going to replace the serial cable as a last ditch effort, but I'm really stuck at this point.

Assuming the unit is actually getting power -- You're going to need to install a boot jumper and try reloading firmware at this point.

Thanks. I tried a second, fresh laptop this morning and had the same results. So I ordered the DIYPnp power source to rule out power issues and install new firmware outside of the car. Will keep the thread posted with my findings.

Thanks again!

Update:

I got the DIYStimulator and was able to reflash the firmware (yesss!). When I reconnect it to the car, it once again doesn't connect/ acknowledge the MS. I'm assuming it's not getting power. :-(

Any thoughts?

I had pulled the fuel pump fuse at some point. So I reinstalled it and tired reading the MS again. It immediately worked.

If things go as planned, tomorrow the car will start for the first time since starting the build in my garage last November. I really really appreciate the help! Thanks again!
