Tuning Idle and Timing on TR224 This is my problem since i put in my TR224 114LSA. The car starts but it seems like its going to die first but it starts. When put into D it does it again. Idle goes down and seems like its going to die but doesnt. Does it a bit when put into reverse but fine everywhere else. I know this isnt normal and it should idle better with my tuning. The idle and timing i guess need to be tuned better. But to what?

Re: Tuning Idle and Timing on TR224 unplug the iac motor and see if it still dies. if it doesnt then you need to tweak the iac tables.
i wouldnt drill the hole out, you can get a good idle without that.

Re: Tuning Idle and Timing on TR224 Another thing that might help would be to let it idle for a while and warm up some before you take off. Even with PCM tuning, the motor will take a little longer to get runing good after you put a cam in. If you have LS1edit there are a few things you can tweak to get it doing better, though.

Re: Tuning Idle and Timing on TR224 I have Predator. Im probably going to do what Norris did. Im contacting my tuner see what he set my idle too. maybe I just need to drill a hole. Thanks for your responses guys.

Re: Tuning Idle and Timing on TR224 TR224 on 112 w/an A4 and I'm idling pretty smoothly at 700rpm (it'll run at 600 RPM too but I think I drilled my TB hole out too much so it's having a hard time idling that low)
I scaled the VE tables down 75% up to 1200RPM, added 2 degrees timing to base spark in park (and drive?, not sure did it a while ago) up to 1200RPM, disabled COT
Found all the info in this forum and combined a few ideas from different threads... warm or cold, car starts and rarely dies (at 600RPM idle I'd get some cam surge and it would eventually die.. )

Re: Tuning Idle and Timing on TR224 My car idles at 1000 in park, 925 in gear. My cam is a beast, so the really idle helps it out. I have the stumble on startup/going into gear thing pretty bad in my car. I have tried every possible thing I can think of with LS1 edit to fix this with very limited success.

Re: Tuning Idle and Timing on TR224 Mine is actually at 800. I saw it at 700 right after i did the tune so i think it took a bit for the car to learn it. But yea now its at 800 all around. It was running really good today. I talked to my tuner and he sent me another tune but with the idle set a bit higher for neutral (and park). But because it was running so good today 
i might not change it. But its good to know I have it if it turns out not soo good. Thanks guys for all you comments and suggestions
