Speeduino PCB for Delco Replacement

Postby Holden202T » Sat Feb 20, 2021 9:06 pm

I have been working on this one for a while, its a speeduino based ECU designed to take a delco 808 header, and the pin out matches a stock 808.

So after a bit of bench testing to prove it all works, i wanted to run it on a car to see that it does actually work, and the only one i had was the FX!

This is basically no tune other than enough that was needed to make it run!



Theres a few small kinks to iron out but generally its a good thing and im pretty stoked!

Nice work, always good to have more options, especially if it can expand on the already excellent 808 capabilities.

Impressive. What's the advantage of using this over a Delco?

it uses tunerstudio so probably a bit more user friendly than tunerpro is, but other than that probably no real differences to if you are using $12P ...

does it have spark cut and flex fuel abilities or the space to add in extras like that?

actually thats a good question, yes speeduino has spark cut, but i havent actually tested it, and flex fuel, i have used a GM flex fuel sensor on the speeduino that this is based off and its got the same circuit in it so it should also work, but it hasnt been tested.

I also connected some high current and low current outputs to the flex pins usually on $12P delco

also theoretically (not tested) with this you could use a 5V square wave crank trigger input, and then the EST output should be able to directly drive an LS1 coil.

Nice def interested in that. I’d be keen to buy a unit and test it. What sort of loads can it drive on the flex outputs?
