hey i’m kylan i got a 1994 NA 1.8L miata i’m not the best at soldering so it is not pretty but let me know if you think it will work or if there’s anything that I should change or if you think it will blow up when I plug it in.

Please stop posting new forum threads. I will merge this one into your other one tomorrow.

In case of new threads I would have to suspect your account.

it started smoking from D1

Posted: **Sun Oct 24, 2021 11:21 am**

Merged the three open topics into this one, please try to keep the discussion of this Frankenso to this topic.

With the way the soldering looks it absolutely is not ready to plug into any kind of power.

If you have powered it up already you may have ruined your board.

Have you been able to look at the frankenso build information I posted and the video to see the quality of soldering you need for your board to work correctly?

Im 100% not surprised it let smoke out. Did you fix any of the obvious shorts or misaligned components? These kits expect a certain level of assembly ability. Getting it Because you are broke is going to end up costing you more money. For $480, the hellen would have been a smart investment.

not starting from +12 could be known issue - see https://rusefi.com/forum/viewtopic.php?p=19748#p19748

so when I plug in the ECU it does not light up or turn on at all when I turn on the ignition of the car it only turns on and lights up when I plug in USB power. tuner studio is also not talking to the car at all and none of the gauges are displaying but it says that it is connected

Why exactly do you ignore my answer at https://rusefi.com/forum/viewtopic.php?p=42747#p42747?

PS: considering the overall state of this project it could be more complicated. Please use digital multimeter and schematics to confirm that Frankenso makes 5v. I suggest checking for 5v on red Frankenso while green brain board is removed.

what do you mean +12 ? what’s that

Posted: **Sun Oct 24, 2021 11:04 pm**

This is what’s happening watch videos please.

Posted: **Sun Oct 24, 2021 11:06 pm**

also doing this with battery

Posted: **Sun Oct 24, 2021 11:08 pm**

also this

Posted: **Sun Oct 24, 2021 11:11 pm**

Wait you connected 12v to this and fitted it into a car?

Have you done anything to rectify the soldering issues?!

Posted: **Sun Oct 24, 2021 11:13 pm**

yes I fixed any soldering points that looked very bad and fixed the capacitor that was smoking

Also the voltage does not drop when I unplug the battery to the car

Posted: **Sun Oct 24, 2021 11:20 pm**

Something is really very badly wrong with your build as there is no way the voltage should be doing what you showing in the video.

I am sorry your kit may now be irrecoverable at this stage.

You may also have done permanent damage to you car by connecting it after we pointed out it is not ready.

Posted: **Sun Oct 24, 2021 11:22 pm**

so what should i do? is there any jumper wires that I have to run on the board or anything specific that I have to do to the board?

Posted: **Sun Oct 24, 2021 11:29 pm**

Please take this vehicle to a professional performance shop.

Posted: **Sun Oct 24, 2021 11:30 pm**

But what about the ECU the car works fine with the stock one

Posted: **Sun Oct 24, 2021 11:32 pm**

Please post high quality pics of the board as it is currently

Posted: **Sun Oct 24, 2021 11:36 pm**

what looks the most wrong and this and the main reason why it’s not talking to the car

where?

this?

Posted: **Sun Oct 24, 2021 11:52 pm**

You still have soldering and misalignment issues. Plus +12 also.

Posted: **Mon Oct 25, 2021 12:01 am**

Have you soldered a 0R resistor in place of the Diode D1 on the green board?

Posted: **Mon Oct 25, 2021 12:03 am**

yes and it has worked fine

is max9926 Super important for the EC you to talk to the car?

Posted: **Mon Oct 25, 2021 12:04 am**

It is the incorrect component.

This may have caused even more damage.

Posted: **Mon Oct 25, 2021 12:05 am**

what is +12

Posted: **Mon Oct 25, 2021 12:06 am**

+12 volts
