Having driven from Port Alberni down to Glenwood Springs Colorado, I unloaded the rally bug to see if the fuel injection system really is going to be better than carbs for multiple events at vastly different altitudes.
It hard-started, but did make it out of the trailer okay. Hit the road though, and it was a big pile of dog-turd. Okay, its not going to compensate for altitude automatically (not surprised, given the system I'm using), so start a fresh map. 20min of run-and-tune later, and things were getting pretty good. But man, I have weird electrical issue that feels like its cutting spark. At first I thought it was fuel, but fuel pressure is good. It
feels like fuel. I'm sure it was fuel. Which pretty much confirmed that it has to be ignition. If you're convinced its a fuel problem, it's probably ignition. If you're convinced it's ignition...probably fuel.
A little while later, it was confirmed when the car bogged and I lost connection to the ECU on my laptop at the same moment the rally computer flickered. WTF? Pulled over, checked all the connections, and figure it's gotta either be fouled plugs or the electronic ignition acting up.
The tune was getting better, however, and the car pulled up to 11,990ft on Loveland pass with zero problems.
It has a really bad hard-start problem though, so I figured it has to be plugs. Sure enough, they were pretty fouled. Cut up my wrists swapping all four in the parking lot, but it fired right up as soon as I was done.
Bring on adventurous Colorado driving!
