Default 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.

There is no need to do this with the Gen 2.

Make sure your timing is correct, and check for vacuum leaks.

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.
