Hi guys. I recently bought an MS PNP gen 2 for 90 - 93 miata hoping to get better control of the idle and the AC.( I was previously using MS PNP gen 1. )
This is my miata's current set up:
'97 1.6L miata with a JR M45 SC, Innovate LC1 AFR, stock injectors, JR AFPR removed, AFM deleted and replaced with GM IAT, VTPS from an AT miata installed, Air valve deleted.
Before the install I added a board jumper for AC idle up connected to Table Switch.
So I got it installed, had the engine running, and the timing set to 10 deg.
Then went on to set VE tables and AFR tables. The new table generators were very helpful. I must say the engine type choices, peak power, torque settings were of great help. After setting that I ran the car and it ran great! ( No AC yet )
So when i got home I tried fine tuning idle with CL settings but couldnt get it to work well. I also tried the AC idle up feature but couldnt get it to work also.
I've searched idle settings on this forum and came across this:
Idle tuning instructions sticky request
- Figured out my closed and open idle valve duty with this.
I've read Megasquirt 2 setting up 3.3 and TS reference guide. Tried to get as much as i can from it but the idle part of it is kinda hard to understand.
I also read on Greg G's thread with his DIY PNP as we have almost the same set up and i know him personally.
I also read that I should start with setting idle with open loop - warm up settings, set my timing/ign table first. But I'm not so sure where to start on setting it up.
So.. can anyone please help a noob set idle and set up AC idle feature. I've attached my msq and datalog.
Sorry for the long write up. Just wanted to give as much info as i can.
