I got a deal on a 1.8 with a na6 speedy ecu.
I got it because I want In engine to build up for my nb2 1.8vvt for turbo.

Is that speedy worth keeping if im building the no vtt engine ?

Or i should keep the vtt and go ms3

I assume the car is running on the Speedy already?

My experience with SpeedyEFI has been good so far, but it seems less developed than MS. There is not a ton of documentation, although the SpeedyEFI guys are pretty quick to respond if you need assistance.
Personally, I like the open source aspect of Speeduino, although I think that leads to a bit more required tinkering.

If the cars already on the Speedy, I'd guess that the engine swap would mostly require swapping sensors. If not, I think you're going to be better off getting an ECU that matches your chassis, not your engine.

I'm newish to this, so take it with a grain of salt.

That seam to be the word. Since I basically bought it for the block. And try to get my money back selling the parts off the na6. Now including the speedy. And reading that the head is better on the nb anyway. I will probably swap my own last min.

Im likely going to spend more time here reading stuff. And getting a ms3
