Any update on the newest batch of PnP units? What's the pricing like? Getting excited over the thought of a cheaper standalone option.

Test unit was finalised on Friday, the main batch currently in assembly now. ETA problem 2 weeks roughly. There was a slight delay due to an issue found with the PCB, so a new revision had to get printed up. Annoying but so much better to have found it now rather than post production

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?

:dunno: not that i've figured out but my starter died and I really haven't had a chance to explore too much yet.

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.

Yep, a heap in stock at the moment.

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?

SpartanSV 07-22-2019 05:02 PM

Yes. The NB system is supported.

ghia nut 07-22-2019 05:30 PM

My unit was one of the first production beta tests
does it need any pins moved or anything added?

lsdlsd88 07-25-2019 02:14 PM

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)?
