I have been reading threads and studdying a bit, but i havent seen any mention of a ready to go MS setup for a miata.. Does anyone offer this? Like a complete built MS, all the sensors and wires and everything you need to go full control, or just ignition and fuel?

 

kingofl33t can sell you a plug and play rig for fuel/spark control. If you choose to DIY it's not so bad. I built mine last weekend and I'm planning to get it in the car datalogging next weekend (following weekend fuel, and the next spark).

 

well i woudlnt mind building one myself... What all did you purchase?? Did you get the megasim thing to test it? I guess if i knew exactly what to buy it wouldnt be so bad. And while asembling it do you have to make any changes to make it work with the Miata?

 

If I had to do it again I'd buy it pre-assembled from DIY autotune. It wasn't difficult to build, but very time consuming (probably about 10 hours including debugging the serial link). I bought a bunch of unnecessary crap because I didn't read enough before I ordered. The kit comes with male and female DB9/37 connectors, so don't waste your cash buying an extra... I also bought the usb card, usb adapter, usb cable, and serial cable... when I really only needed on half or the other.

Check, DIYautotune.com under the installation articles section for miata specific directions. It's a well written article. If you still don't feel up to it then spend the dough on Kingofleet's plug&play setup.
