So I have the first beta designs just about finished for the NA8 64-pin ECUs. I need to find a test car or 2 though before I'm comfortable with selling these to a wider audience. The NB8A 64-pin unit won't be far behind either :)

Hey!! , is it possible to buy one to assemble and a fully built harness to make it a PnP ?
If so where/how do you get a base tune ? Thanks. |

In my opinion, the best setup is something like a 36-1 wheel on the crank and a single cam pulse. That gives you everything fast sync for starting, full sequential and good timing accuracy. It is a pain to get a 36-1 wheel onto the crank on these engines though, so I haven't seen a lot of MX5s/Miatas go that route (It's a VERY common setup on other vehicles though and very well tested with Speeduino).
It does for fuel (The California models run sequential as standard) and these boards have the drivers there already for it. You just need to cut 2 traces, which are designed for this. Ignition is trickier though as there wasn't ever a version of these that had 4 drivers from the factory. These PNP Speeduino boards only have 2 ignition drivers on them, so they're limited to wasted spark, which is what the car is wired for. The generic v0.4 Speeduinos have 4 ignition outputs, but aren't as straightforward to wire in as the PNPs. |
So, the Speeduino Wiki says about the PNP:
If the AFM is retained then this sensor will work if jump wires are run from the AFM to the disconnected connector |

From what I see and read on the wiki site, the v0.3 board has 4 channels for ignition as well as 4 for fueling. Is that not the case? I’m not afraid to build one and go the v0.4 route if need be though. Alternatively, will I be able to just run a wasted spark coil on/near plug setup? Is that a thing? |

Some people like to keep it there initially when they do the switchover, just incase they need to go back to the stock ECU. In those cases I generally recommend disconnecting it so that the fuel pump control and things don't interfere with the control from the ECU etc. It's not mandatory, but it's how I suggest people run it whilst it's still there. |

But that still doesn't explain how the "disconnect but jumper" business works. |
you disconnect the AFM plug, BUT you run the 2 wires for the temp sensor, between the AFM connector and its plug to restore only the IAT functionality but leaving off the AFM signal and the fuel pump switch.

Yeah you can certainly go that path. I ran mine like this for quite a while and made an adapter board for the v0.4 to interface with the 48 pin connector.
It's definitely a thing. Practically every COP/CNP conversion I've ever seen on these cars has still been wasted spark. Unless you're running crazy high rpm (Think 10k+) or using coils with extremely long dwell time requirements, then there's no real reason you need to run sequential ignition. |

So, there def are not 4 ign channels on the v0.3.7? Cause the wiki site and the pic of the v0.3 board show 4 ign channels. Just clarifying;

Small update on things.
The initial PNP units have all seemed to be pretty successful. Most people who have them seem to be up and running and I haven't heard any major issues back :) A small design revision (v1.1) has been finalised now and is going out for manufacture within the next 1-2 weeks. This mostly addresses some compatibility issues with various later year / Euro spec models and things like A/C. There are no feature differences for those with working setups now (Apart from possibly the A/C), just further compatibility. The list of changes for these are:

Are you saying that the previous batches won't work with A/C?
|
Been running my wifes miata with this for a while now.
Have any of the firmware updates addressed starting sequences where the ecu primes for start. Her car still backfires horridly on cold starts. If we cycle the key on off on off like 6 times it starts much better. |
what firmware are you on? post tune and starting log (with and without the 6 key on key off..)

Anxiously awaiting to see these go up for sale again...

The order size for these is growing with each batch, but the factory has completed the first test unit of this run, which usually means the full run isn't far behind. Hopefully just a few weeks before they're back in the store. In terms of volume, there's somewhere around 120 of these PNP units out there already, which simply blows my mind, so a big thanks to all those who have shown interest in the project! :D |
Any plans on adding VVT support?

Step 1 is in incorporating cam angles (as opposed to just crank angles) and there is some early code for this already, but it's definitely a WIP |
Any update on the newest batch of PnP units? What's the pricing like? Getting excited over the thought of a cheaper standalone option.

Pricing will be the same, $240 USD :) |
Fired up and drove my car last night for the first time on Speeduino. So far I am pretty happy with the whole thing. Gonna start making the installation more permanent and add some features like tps and wideband. Also, need to get my ac triggering again.
|
Is there no AC idle up?

Still need to figure out how get it to idle up when the compressor is turned on. Idle up was added to the last software upgrade, but I haven't checked what is required to make it work. |

Is your AC not turining on or not idling up? I built my Speeduino and needed to solder a jumper wire in my Speeduino to make my AC work. Still need to figure out how get it to idle up when the compressor is turned on. Idle up was added to the last software upgrade, but I haven't checked what is required to make it work. originally was doing nothing. I too had to solder a jumper and a diode in. So it functions fine now, but no idle up. I need to investigate more. |

Hey, we shelved our speeduino for a bit but would like to dust it off and give it another go.
We are looking at installing a mazdaspeed miata engine. Would speeduino be able to use the crank trigger as well as the cam position sensor from the msm engine rather than using the 1.6 CAS, essentially wiring it like in the vvt swap master thread? |
Yes. The NB system is supported.
|
My unit was one of the first production beta tests
does it need any pins moved or anything added? |
depends, do you have any issues? if it ain't broke.. I'd recommend to update the firmware :)
|
Thread bump!
How is everyone going with thier speedies? I'm just about to fit a no2c to my 1600 turbo.. Does the no2c need any other mods to the board? Does it need the 1k resistor for tach? Do I just wire the fuel pump wire direct to the no2c (after removing the St fuse)? |
