RX-7 460cc injector upgrade and motor rebuild - Chasing my idle
#1

Hi guys,
It's been 2 years since my Miata was last running. I recently rebuilt the 1.6 and installed Rx7 460cc injectors. My tune prior to to the rebuild idled fine and ran fine with the Tan top injectors from the NB miata.
Nothing else changed. Could I have a bad IAC? Why am I running so lean? I am currently reading over a bunch of threads and documents but wanted to chime in to see if anyone can give me any tips on what to look/start with. Any advice is appreciated.
Attached is my .msl attempting to idle.

I had to fine tune it to get the engine to stay on as it would die. It idles now but high (1500), oscillting rpm between 200 to 400 rpm depending how the motor feels that day, and my AF is pegged lean.

Changing the injector settings in MS will result in really just a starting point at best.
Need to re-tune your car. It may never be awesome, those injectors aren't the greatest. People ran them for years without wanting to burn their car to the ground, though. With enough time and work, should be able to have something that at least works.
