Hey I was planning on using a haltech 750 for my 07k 944 swap. But then I heard about speeduino and was wondering how much I would be giving up going the DIY route. It's quite a bit cheaper but I wonder how much less functionality it has. Does anybody have experience with the speeduino or other DIY ecus. I and I compete grassroots endurance racing to give an idea of the budget and project scope.
