Semi late to the party, but Link is having their annual black Friday deals, 11/3-11/28. Great time to pick up your pnp or wire-in ECU. 90-95 2-plug ECUs will be as low as $1190.00*, all other Miata models as low $1355.75*. I know of at least one converter box to put an NB1 ECU into a 95.5-97, I myself have made a 90-94 work but it takes a lotta time and effort, and NB1 ECU gives you a knock output, among other benefits.
*That's what they should be for the Black Friday deals, seems hit and miss which vendors are actually displaying those prices.
Any recommendations for a reputable vendor? Tried AR but nothing in stock on the site (can call if needed), and the dealers shown local to me on Link's locator are either unreachable or out of business (or both).
Yeah our website sucks, plain and simple. Email Me at martin@arautoservice.com and I'll get back to you with pricing. You could also try KO racing. We’re both smaller shops, seems like the bigger and more accessible the shop, the more up charge they’ll tack on.

Few days late to the party, but Link is now having their March Power Sale, now until the 3/22. 10% off all ECUs, PDM, looms, and CAN Lambda. Miata ECUs are the same price I listed above.
