Hi y'all!

So I recently got a turbo miater, and have put 700 miles on it without any issues. Buckets of fun. But, it has a 1400rpm idle.

So, I plugged into my MS3 on my '99 turbo miater yesterday and was just looking through the tables and stuff to see how the previous owner set it up. Then, my computer died, while it was plugged in. Then, my idle started climbing up and beyond 3k really fast AND going really lean at the same time, so I turned off the car.

Today, I went out to try and find the problem, and I couldn't figure it out. Each time I started it, it did the same thing. So I tried setting up a closed loop idle, same thing. Then I tried going back to open loop, and I shut everything down, disconnected the computer, started it up, and it went back to normal (which, again, even though it's high, is smooth, steady, and driveable). I saved that file as TUNETHATWORKS.msq and went for a drive. All good.

So I get back, make a new file, and start tinkering. Nothing I did seemed to help, so I burned TUNETHATWORKS back onto the megasquirt, started her up, and... F@#(*$(K. Back to the scary idle climb and leaning out!


Here's a 20 second video of what I'm talking about.

I'm new to Megasquirt, so I'm hoping there's something I'm missing that might seem obvious to someone else.

Thanks for your help!

Datalog really helps more than a video. What’s your TPS at?
