I reset the CLT-related air density to be coolant based "normal correction" and flattened the curve to 100% all the way across the range. I got the car up to operating temperature on the OBD2 computer ( Read more... )

I think that I'm missing some crucial understanding of what is going on in the MegaSquirt at different IATs, because it's not nearly as predictable as I had expected. The first air density correction curve that I came up with seemed to work amazingly well at idle, but as soon as I started driving around ( Read more... )

Unfortunately, I was so distracted with other gauges that I neglected to see that my voltage had dropped to nearly 9 volts, causing the car to die. Fortunately, I was only ( Read more... )
