Long story short, I installed a speedyefi on my car, couldn’t get it to run right for the life of me, shops around are asking about 1000 for a tune plus hourly, and so I was wondering if a remote tune is cheaper than that (I’m a struggling college kid lol). Basically I have a 1990 Miata, with a cold air intake, racing beat headers, catless cobalt performance exhaust, and so I just would want the car to run like normal with all the mods tied together on the new ecu so that I can get comfortable with speedyefi and eventually one day turbo her when she’s more built up. Again any ideas of quotes and tuners? Thanks guys you’re the best

I can't comment on who would tune it for you, but I will say that with your setup up there is very little risk of damaging your engine or anything like that as long as you don't mess with settings that you don't need to mess with/don't understand. I'd encourage you to try and keep learning about it like most others on this forum have. It really isn't too complicated, it's just trial and error then tweaking it to reduce that error for the most part. I believe with Speeduinos you can still use TunerStudio's autotune feature and that will help get your fuel map 90% of where it needs to be (this feature does require the paid version of TS but it is 100% worth it). Just be sure to lock it out of the decel/very high vacuum cells (30kpa or less is usually good), lock it out of the idle rpms (700-1300 rpms) and tune those manually to target the AFR table that has been included with your basemap. Also, just don't even bother with messing with the ignition table (unless you're removing timing to be safe) as that is where real problems can arise if you do something stupid.

A really good thing about this forum is that people will likely look over your tune to make sure it looks correct and safe. I'd encourage you to upload a screenshot of your AFR, fuel, and timing map as well as your tune file. Also, I was in a very similar place to you, except I actually started tuning my own car in my senior year of high school. It will take some decent effort, but if you learn about it now it will make things so much easier if you ever do go the turbocharged route like you wish to.

Only thing that might be tricky for a beginner is the Acceleration Enrichment settings, but the basemap might be fine if you're running the stock injectors. Also, what issues are you currently experiencing in terms of not being able to get it to run right?

There are some facebook groups for SpeedyEFI/Speeduino who have some respected remote tuners. Tunes.speeduino.com can also be a good place to poke around on, although some of the tunes on there are mediocre.
A lot of Megasquirt video's will apply to Speeduino as well. OGPedXing and TheCarPassionChannel have some good beginner tuning videos.

If you want to go through the forums, post a tune, explain your specific issues and post a datalog that shows the issue.

This is actually helpful asf. Tbh when me and my friend installed it we tried to tune it but removed the whole ecu because the car is my daily and I had to get to class the next day and we where slumped on what to do so right now I’m currently running the stock ecu.

as for issues. I remember the car ran rather rich and that it also had horrible throttle response and was super jerky and uncomfortable to be in. With speedyefi I know you put the new tps sensor but I don’t know if it has to be at specific angles like stock? (Never seen videos saying that). I just got the car running fine again so I want to try this out soon but it’s worrying

If you installed a VTPS there is a menu to calibrate it in tuner studio. I've never dealt with installing one (they're stock on an NB), but the calibration is just getting a reading at 0% and 100% throttle.

Yeah, sounds like a base tune. If you didn't do any tuning to the fuel table then AFR's are going to be all over the place.

Throttle response/jerkiness is probably Acceleration Enrichment like Watterson mentioned. I believe it is turned off on the base tunes.
