soa re you currently running 18* of timing or lower? you mentioned max timing originally was 28* correct? could try and run 14*. i don't know if that low would exhaust the danger zone of high EGT or not. stock timing for LS1 i thought was 16-17*?

I believe the 5k delay is only on trucks, not on fbodys, havent seen the thread for awhile so forget what hes got. The concern is the opposite, if power enrichment doesnt kick in it would go lean not rich.

So what you are saying you would make a full 1/4 pass at 14.6? .It takes more than rpm to trigger pe but I will assume you know that.

I am tuned at 28* and pulled -14* afr correction.I did not want to go farther in fear of burning an exhaust valve.

any idea on what the turbo'd guys are running regarding timing and boost? the heat generated from the turbo would be way higher than N/A setup if they're running around 12-16* timing in their setup I would think.

Not sure.. I did not get the results I wanted quickly so I switched classes. I just did not have enough time to keep trying. Someone told me I could pull 18* but like I said,I just ran out of time. I was also told if I kept cutting back on throttle position and I did not meet the map value I would not go into pe.I could of changed the value but everything was working good so I left it alone.

I widebanded my 6.0 and it was happy as all get out running around at 15.0 Even when it hit PE it was only dropping to 14.0s. These older computers arent the best thing in the world. Just checked a stock 02 Camaro tune and PE rpm delay was 5500 rpm. Delay MS is set to 0 so that may counteract the rpm figure. I have little experience tuning with stock tunes, I generally change them before the first drive. Regardless, 14-15 range on a non-boosted application will be a non-issue other then power may be down a tad.

Hey nj, I was running Into this issue as well. What about just lowering your shift rpm since removing timing isn't working for you. If your flashing to 5k and you think 5500 may be to fast, maybe 57/5800. Worth a shot anyhow. This is working for me for now.

And you are verifying that it is actually pulling the amount of timing out that you want on the log?

Yes I logged the car 14* entire run. I tried 5900.The most I slowed it down to was 11.10.I am going to make a new shifter plate and go from 1 to 3 and see what that does.

just to be sure, have you logged all this stuff and can confirm you're at 14 degrees and shifting at 5900 or whatever it is? At 14 degrees the car should be a dog so going 11.1 is hard to believe unless the car weighs 2000lbs.

On bad tracks, I've left with as little as 7* total timing ramping back on over a second.

Yes logged, I had -14* in the afr correction table from 4500 and up. The shifting is done with a shift light.

could prolly add something to block the gas pedal from going al the way to 100% throttle if you cant adjust the throttle cable on the throttle body :-p
