Alright folks, it's been awhile since I've posted and I've got a good one.
A little background, I bought my 1996 miata last winter and have been cleaning it up, making it reliable, giving it a comfortable garage and love ever since. The only thing that was gleamingly strange with the car when I bought it, was... It had an AutoMeter boost gauge installed in the A pillar in a single pod. It was clearly not turbocharged when I bought it, and at some point somebody sunk a decent amount of money into the RB headers and exhaust. Now because of this, I was obviously skeptical that it was boosted at one point in it's life. Cautiously optimistic that it was just being prepped for a turbo build, but still skeptical. It wasn't until a few months back when I installed the FM frame rails when I peeled back the carpet, and saw what was going on with the ECU...
I thought that was the final straw. I'm still new to miatas, and even newer to the idea of boost, and so I figured asking the experts would be the best way to go about this.
So, in a roundup what I know..
-The car has a boost gauge that has a power wire that runs over to the ECU area, and a vacuum line that runs through the firewall but not all the way into the engine bay.
-The ECU AFR wire has been tampered with.
What I ask of you guys here, is if you can help me investigate to find out what this car may have been up to in the past?
