Hey folks, I'm creating this thread so I have somewhere to go in a few days when I start trying to tame the idle on a friend's LS1/t56 in his Mazda RX7. He hired my services to tune the engine and so far we've got VE and spark tables fairly dialed in. It's got stock 241 heads, stock compression, but ARP head studs, ARP rod bolts and the necessary valve train to wind up to 7000rpm's. The cam is a 236/236, .569/.569 on a 112LSA - and it feels like it too. ALL high end power, but it's a fair-weather only car meant for fun. We'll be working on it all summer so this thread is just a place to go for questions along the way.
I'll be sitting down with the car in a couple of days to log and data collect during a cold start situation. My goal is to really nail down idle perfect. For him, it's been rough trying to keep the car from dieing so that's my main focus. The car likes to die when coming to a rolling stop.
For starters, here's the latest tune file. If you see anything out of obvious wack feel free to correct me. In a few days I hope to spend a lot of time on idle.
