Gday stranger, nice to see you back.
I hope you've slung a towbar on the back there, then you can whip down the river and chuck in a quick rally stage between runs. Although big block is goign to make her a wake boat :)
 
Fancy an expenses paid trip to sunny Geelong to do some spraying? 
Marty dragged me into the ITB caper, after buying a full set of Honda ITBs as pictured earlier. My set cost under $100 shipped. Then the plan was to buy an inlet from the UK or 3D print as we are doing.
Speeduino came up while learnign the other bits needed, and what I liked was its open source, and support is much more readily and freely available. There is a bit of a learnign curve, but with our case using Pintos', its pretty basic setup and peeps have done it before.
 
Plus, the head speeduino dude is just in Ballarat, which is good to 'buy local'.
So far, the Speeduino itself cost me around $150, but it should have been less cause I buggered up on the componets to buy, and needed a second order.Plus I changed the format of the case to make hooking up easier.
Check out 'Making for Motorsport" on YT if you havent already, David does a pretty good intro, and also prints his own manifold. What engine are you planning? Theres a high chance Speediuno will cope with it, and theres likely to be a base tune available as well.
 
I can just about use a timing light, thats the extent of my tuning knowledge, but we'll give it a crack, and see how far we get. Can always ask for help on the SP forums.... (or go back to the 32/36)
 

so long as the forum doesnt meltdown from the sudden flurry..
 
Mark if you want to join us in the Speeduino sandpit and play around with the soldering iron at the same time, send me your address.
I have a previous model 4.3 board and some componets you can solder in (was pictured earlier on in the thread), not much of a challenge but gives you an idea if making a board yourself is the go or not. You can buy them completed of course, or in various bundles with the Arduino:
https://sparkefi.net/ is a cheap supplier, even free post to Aus. Just takes a while to get here.
 

Speeduino controlled small block speedboat.
It does support launch control!,
 
Imagine the look on the skiers face, being launched into outerspace, classic.

My bro used to do the circuit board etching in the 90s , 1 good thing is he brought home some real flat and stuff boards which didn't make the grade. I remember using 1 decent size to make a chassis for my competition RC buggy, it was bare without copper. The chair plate made my buggy underweight by a 20c piece, this was in the early 90s and the buggy got me to state champ qualify in 2wd modifieds , came 3rd outright. The board never broke even with some monstrous crashes it went thru, even a small fire in the track lol... Good old days
