Can I see your ldle settings?
Hey guys, MS2 PNP brain built on a 99 miata. I cant seem to get it to stay idling consistently and not dropping down to 4-500rpms at certain times after some hard acceleration and not just drop down to 8 or 950rpms where it should be. It comes off and on at times and doesnt consistently droop, but when it does and the car is cold it will often stall. I was wondering if some of you could post a screenshot of some setting you have in tunerstudio to nudge me in the right direction. I scoured megamanual but am not getting something, maybe seeing what you have plugged in will trigger it.
I am running PWM closed loop if that helps. |
Could you post a data log of your problem and a copy of your MSQ?

Matt, heres my file, as for the datalog, should I go run the car, rev it and let the idles choke out and idle low like the described problem while running a datalog? Should just one occurrence be good?

One occurrence is good, a bunch of them is even better.

For whatever reason, when I started it up, it only went there once right at the start and didnt give me shit for the rest of the five minute or so drive. The first few seconds or so might show you the dip and then it stalls.
Its doing this weird "rev to 1300rpms" shit after it warms up and if i dick with the pedal and pull it back it reduces it to 900 flat. However, it did drop down to the 500rpm and stay there once, but that may have been after the logging was finished. Heres the file. |
Some oddities in there:
RPM with valve closed is greater than RPM with valve open "Leave valve closed above" set to 400 |
Thanks for taking a look! I will update that tonight. Any other suggestions?
|
What results did fixing the things I listed get you?
