Ive been running the mspnp9495 for about three weeks now and i have just recently started having a problem with the car dying whenever i let off the gas with the A/C on. I cant think of any changes that i have made that would cause this. I'm pretty sure there is any easy fix for this, anybody know what it is?

 

The new idle settings that jerry posted seemed to fix everyone elses problems for the most part. Have you loaded them yet? So you have a variable TPS?

 

Here's the info on these new settings-- https://www.miataturbo.net/megasquirt-18/mspnp-mm9495-base-map-update-available-12539/

Note the one that is car specific, info is in the thread (and manual) though
