As used on the Stage 1 turbo kits for the NB, this simple wheel replaces the stock trigger wheel on the crank nose. Unlike the stock piece, it leaves a bit of room for adjustability. The ignition can be retarded by up to 8 degrees or advanced by 4 degrees.
Adjustment consists of simply loosening four bolts on the crank and rotating the wheel. An indicator shows you just how much you're retarded or advanced compared to stock.
I got this super fast very thankful saved my week
Just like the other review, there were burs that made it difficult to install. Once you shave it down and get it to fit, it does what it's advertised. Very straightforward process, RTFM, especially adjusting the crankshaft position sensor. Had an issue where the miata will die after cranking and it's because of the position sensor was not spaced properly. Butt dyno, after adjusting the timing to 14 degrees, power band starts a bit earlier, feels nice.
Reason for the three stars: for a flyin' miata product, they really couldn't de-burr after the cut? After seeing the response for the other review regarding the burs and that they'll go through their inventory, purchased this thinking I wouldn't need to de-burr... Guess they missed mine.
Carefully grinded the center bore a little with a dremel tool to deburr and enlarge size to fit. It’s a tight tolerance part, better that it came slightly small than too large. Very happy with the FM version for naturally aspirated engine because max timing advance is +4, set it and done.

Oof. must have been a bad batch. The one I received also does not fit. Visible protruding burr. I tried sanding it but could only get the color off. Sand paper did nothing to the metal itself. Maybe I should try grinding with a dremel tool.
Note from FM: we are currently inspecting our inventory and will work with the manufacturer to ensure this doesn't happen again. m1yeh, if you have not contacted our customer support team for a replacement please do so.
