PLEASE SOMEONE HELP! before i go part this POS out. if you can fix ill pay
ladies and gentleman i come to you tonight in my darkest hour I have been up every night of the last week and a half. All I'm trying to do is get mar car running again, but i cant even get one if the three laptops i have to establish any kind of connection with my MS.
so quick little background this is a mspnp unit built by braineak it was running fine having been tuned by a pro shop about three years ago. Then the engine spun a rod bearing so i started the ever long process of rebuilding it. since then I've moved 4 times gotten married and even survived a pandemic, the last one I'm kind of regretting at this moment. the car is a 92 with a 1.8 swapped fully forged engine t25 turbo.im running all stock ignition systems and RX8 yellow top injectors. so on to what i have tried so far. its worth nothing that when i say i tried something i tried it on three different laptops 2 using the usb converter "hassle free" sold by diy autotune. the 3rd computer i went out and bought just to see if the damn thing would connect to a computer with a true serial drive. i have tried re-installing , updating , the drivers (to my knowledge I've done this best i know how it may not be right but i think it is) I have tried getting power off the miata harness to make sure its receiving a power supply. it was getting 12 volts i have sent it off to be looked at by someone recommended by DIYauto at the very beginning because suspected it was damaged he said it was fine. i have tried plugging it in each of the laptops ports individually i swear i have tested damn near ever port and baud setting ive ever seen my computer display i had a guy from my local Miata community come look at it today with his laptop and he has a running megasquirt in his car. i have used the port detector file provided by DIY it says i have two open ports. i have tried just about everything i can think of and I'm still not getting jack shit its worth noting that when we initially just tried to start the car or get timing i was not getting any spark from the megasquirt but would from the stock ecu. i say it this way becuse it may also have been my friends really shitty timing light but i don't know i haven't tried since then. i was having to replace a crank pulley instead. i have to be honest with everyone in here this was my very first car i bought I've kept it nearly 8 years now and have gone through engines trans a rear end and a ton of mods. i have loved this car like its my own flesh and blood. it has truly been one of the great joys in my life and i don't want that to change, but i am so damn frustrated I'm at my damn wits end! its been broken 3 years and i just feel like its to far gone at this point. PLEASE SHOW ME IM WRONG PLEASE HELP ME FIX THIS!!!!!!! NO LIE I WILL EVEN PAY YOU. https://cimg6.ibsrv.net/gimg/www.mia...afbcf7e294.jpg |

When the USB adapter is plugged into the laptop (dont plug it into the MS yet), does it show in device manager as a serial adapter? if not, does it show some kind of unknown device? |
My troubleshooting steps would be:
-above^ -Make sure comX is correct for the port being used in detect page of ts -proper/updated drivers for cable and usb ports -junk cable? |
so the cables are new from DIYautotune. yes the guy from a local page who came and helped me could not connect either. it shows it as "usb serial port com4".
I really have no clue what I'm doing wrong here. |
I was having connection issues with my no-name serial USB until I bought the $12 dollar "Sabrent" brand cable from Amazon. I went into device manager and changed the bit rate to 115200, and switched the port to COM1 and it worked like a charm. Connected instantly. It worked with my friend's old Windows Vista laptop as well as my newer Windows 8 laptop. You said you already tried playing with the port settings though so that's as much advice as I can give. Good luck!

So this evening with my older laptop direct serial port connection I tried using a power source out of the car i ordered and it connected perfectly. WHAT THE HELL?!
I swear i checked and i had 12v power on the harness. What gives ? what could be causing this? what wiring should i check. i will also note that the starter is now having trouble but i think that's from cranking the motor to much. i also replaced the battery for good measure. Anyone got anything? maybe someone could tag revenant or braineak I'm not to sure how too on this forum. |
I'm having the exact same issue, I've sent mine back and had them reinstall the original firmware and tune file to see if it would work. I wish I had more answers for you but I'm commenting just to follow the thread. does your fuel pump kick on and run non stop? are any of the 4 lights turning on when plugged into the car?? Good Luck!!
