Getting Started: LO3 Camaro

Put about 120 miles on it last night. Starts great, runs good, BLMs are in line when driving.

Still rich at idle. 110ish on BLMs. And it hunts at idle in gear and park. There's an idle/spark correction PID I've heard about disabling to help with that. Might start emulating and try and tune it better or I might drop the PID completely for now.

I want gears and a TrueTrac but I also want headers and a better exhaust and cam swap and ya know, EVERYTHING....
 
Spent yesterday and today getting cooked on the paper machine and it's too humid to think outside. Car will have to wait till I can be outside for 5 minutes and not sweat through my shirt....
 
Tonight was not as miserable so tonight after dinner I played with the car a little.

First thing I did was turn the fuel pressure up to 13psi. My O2 voltage was in the 800 range at WOT and I was getting a good bit of spark retard so I was pretty sure it was leaner than I wanted.

Next I decided to try emulation. I cut the idle overspeed and underspeed spark tables in half and zeroed the idle multiplier tables and that stabilized the idle RPM issue I was having. Then I played with the idle speed a little and leaned out the 600x25 to 800x40 section of the idle VE table 5%. That brought my idle BLM right to 128 and seemed to improve idle quality some too.

It seemed to go ok till I started getting blips, CEL would flicker and the idle would jump to 1000. It eventually died and wouldn't restart. I fiddled with it and decided to swap back to my chip. It still wouldn't start. I unhooked the battery for a few minutes and it still wouldn't start.

I suddenly fired up and idled. I swapped back out to the Autoprom, it started, idled. Cool. I pulled it in gear to go play a little and the second I hit the gas pedal, it died and wouldn't even try to restart.

I swapped back to the chip, cycled the ignition 3-4 times and it fired up. Not wanting to get stuck on the road, I burned my changes to the chip and just drove on the chip instead of doing any more emulation this evening.

The car runs tremendously better with the 13psi. 5500RPM easy between 1-2. Much more responsive 3-2 downshift acceleration. I have a long log to review and see what I want to change next.
 
I finished mowing, weed whacking and blowing the walkways clean at 11:45. Almost brain farted when I walked into the cool house to eat lunch. Got real dizzy.
 
Took it out this morning doing some emulation and it ran OK for about 40 minutes. It started struggling so I popped the chip back in and headed home. I parked the car and went in and made some changes I wanted to burn to the chip and kept getting a validation error. I chatted with Craig at Moates and it looks like my Autoprom burned up a component so it'll be headed back to him for repair.

I was able to emulate and get the car back in the shop. This is my kinda luck.
