Just a quick update. Everything seems to have gone fairly well with the initial beta run. I believe most people are now up and running (at least out of those that have tested it) :skid:
I've decided to do a second beta run though, just to improve a few things here and there. The differences are:
If anyone is interested in one of these, shoot me a PM and I'll reserve one for you. Price will be $180USD + postage (I've decided the final retail price will be $200USD, so the beta runs are slightly cheaper than this) Have any of the beta unit cars been fully tuned/in use/etc? |

I am amazed at the progress of this. I am not a computer guy so this stuff really boggles my mind. This is some great work noisymime.

Cool stuff, nice to see this isn't dead.
Have you had any issues with the speed limit of 16Mhz? Thought of going ARM? That said, the code is cross compilable for the Kinetis (K65) MCUs (Think Teensy 3.5) and support is being added for stm32 currently (Though these are a bit more limited). As it stands though, there aren't any extra features for those as there's nothing the Mega can't run. |
I think that's damn impressive then for what you have it doing, you're a far better coder than I am. Well done.
|
So after a couple of delays (Thanks Customs!) the beta 2 units are finally ready to go. I've sent an email out to those who were on the beta list, so these should be all going out shortly.
Simply because the question of ARM procs was asked above, this might be of interest: |

Was it a batch of 10 again? Also how many have been claimed out of how many produced? I may be interested in another unit some time in the near future. I also have had a bunch of people who are also interested. You should definitely update the speeduino website with a page to post progress, sign up for mailing, post info, etc.
I'm preparing the design files for a larger run now and will pull the trigger on this as soon as I get some feedback on this batch. Send me through a PM as I've got 1-2 of these spare if you're interested. |
Question: do you need a wideband to get one of these running?

Just saw this for the first time and this is awesome! Will be following the project and waiting for v2 :party:
|
So initially installed speeduino, wife laid off and needed her Miata to get through the layoff and I put the stock ecu back in.
just reinstalled and after working with the unit a bit it idles ok. Original idle was Stoopid pig ass rich, like so rich i may have to clean the plugs. So far I'm really pleased with it. My friend that's a tuner, who would tell Jesus the correct way to make wine, is going to mess with it Tuesday so he may or may not complain about it. So far from my perspective two thumbs up!!! |
anyone would share a "roughly fine" MSQ for speeduino with 1.6 miata?

Because the meaning of base map can be very different. |
It's a bit rough

so is this behaviour to be expected on a base map and mostly stock engine?
Because the meaning of base map can be very different. We tuned all day yesterday and got it running fantastic. Adjusted spark tables. Had knock ears on. Very pleased with it. Pulled great. Responded well. Went home and cold or hot won't start for shit unless you peg the throttle bad. The start up is an absolute nightmare on this currently and the ability to tune this is kinda wacky as the normal tables you would expect with a Ms are not the same. My tuner tried to plug in correct values for the fuel injectors and it went South so I reverted it. I've gotten it to idle back so it's been touch and go. Will report report back. currently using Gm iat Auto trans tb with v tps spartan wb correctly setup All wired per manual. |
plugged in mine today also!
I think I will fiddle a little bit with the idle screw because right now it starts quickly if i press the throttle just a bit, but does not like starting with 0% tps. about the mapping itself I still have to wire up the wideband, iat, and run the vacuum hose NOT through the passenger window so it will take me a while to get really ready ;) |
Finally updated the firmware so we know how to do that now.
Think we may start back from scratch. Im just happy we have it running again. The biggest issue we have is start up and cranking settings as it is super duper pig rich. WUE Acceleration enrichment Also any help info with idle control either the idle switch or idle air control valve. We can take care of the rest of the tune. |
If you're able to post your current tune and a matching log of it starting, running, Accel enrich etc, that will give me an idea of what's going on.
Generally with the idle, I've found on the cars i've worked on that I haven't need to modify the screw too much, if at all. The IACV in these things is fairly easy to tune and I'd recommend going with open loop for it unless you really have a reason not to. You'll save yourself a heap of time. At 0% duty, the valve is partially open as a fail safe mechanism, and is not fully closed until about 35% DC. I've found that have 0% duty when cold, raising up to this 35-40% DC mark when warm works really well and should give an idle that drops from ~1100rpm when cold to about 800rpm once warmed up. |
I think we made some base assumptions that bit us in the fanny on this one.
I just compared the original base tune to the new base tune from the Dec 17 firmware update. There were some changes, small but hoping significant. Also I'm now assuming this is to be used or started with the stock Miata afm in place right? Given that the new air intake vs stock is more efficient this would cause some headaches (running under load isn't horrible to tune due to ve analyze live, but anything down low may be problematic) We started with a cold air intake and gm iat so this may have added to the learning curve on our end. Going to write the new base tune with correct sensor scales and see what happens tonight then go from there. |
