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): https://www.miataturbo.net/ms-labs-m...oup-buy-50791/ 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:
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 Much of it seems outdated, not applicable, or even redundant.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 through

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/) |

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.

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 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? |
check yo fuses?

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! |
do you have the basemap you used for this? i have ms2 enhanced from rev and am having hard time finding base map
