Question about MSPNP2 for 1.6
I have recently been messing around with my new MSPNP2 (getting everything set up) and I was curious about a few things.
First - I have read around on the internet that with megasquirt i should unplug my TPS since it isn't a variable TPS and to set the open/close values at 255. Should this be something I do with my MSPNP2 or not? Second - I have started my car once on the megasquirt i have applied the base map, and have set the timing to 10 BTDC. my issue is that the car idles at 2000 +/- rpm from cold to warm. Now i know it could be simply because im running a base map. but i have tried using the idle air screw to turn it down with no help. Any help/tips or tricks is appreciated. |

so can i leave values of 0 for the open/close for the TPS?
The 10 degree's is the initial 10 while setting timing initially. I assume that this could make my idle high? I have checked over and over for vacuum leaks. If i plug everything back to the normal AFM the idle is normal. 900/1000 rpms. no sputtering like a normal car would if it were stock. |
That depends on whether the TPS reading is steady or not - I'd rather have a bit of a spread so it stays steady.
Do you have a data log of the idle and a copy of your MSQ you can post? |

I do have a .msq file but its the 3.3.0 base map.
I did not run the logger when i first started the car so i do not have a log. attached is my .msq file. |

Update:
I changed the map to use the default timing map just to test it and I created a log file of the data. Please see attached and let me know where else I could look to adjust the idle speed of the miata. Also, I have tried adjusting with the screw on the throttle body but that does not help at all. thanks for taking the time to help me out. |
Looks like you've got idle control switched off; change it over to a PWM valve and that should get it working.

Ah I see, I will have to change that and try it. I thought I read somewhere that said the miata was an on/off type or something. Maybe I just read the article wrong.
Thank you for the help and if I have any other issues I will update this thread. |
