LOL! Don't say that too loud on this forum.

Post the slip, or at least tell us what your 60' was on that pass. DA was similar last night to your previous 13.46@105.69 and I'm thinking that the 60' alone could have dropped you a tenth or two and picked up 1.5mph.

Did you get any before and after numbers with the new tune, or wasn't it done on a dyno?

Your wisdom exceeds your post count for sure LOL.

But a 10:1 A/F, and shifting like an 80s Cadillac? I only wish I'd known what a good tune felt like a year ago. The soot accumulating around my exhaust every 3 weeks should have been a red flag...

You obviously never logged anything to show Ted that it was that rich and shifting poorly. Ted always wants a log after the first tune to tweak it, he would never have a car that rich, I had several tunes emailed from him although I did switch to a local tuner, he tunes similar to Ted and the talk regular so it was more a convinence thing for me.

Dyno tuning followed by fine tuning on the street is the best choice for tuning.
Especially if you have more extensive modifications such as an aftermarket cam, gears, converter, etc.

Mail order tuning using data logging would be a second choice if a skilled tuner is not available in your area.

blufin · 07-29-2012, 05:48 PM

I'm not sure I would call about a .1 and 1.5 mph improvement lightyears better. Could it have been better air on the latest run or a better 60"?

.1 improvement in the 60" will equate to .2 in the 1/4.

Revo1 · 07-29-2012, 06:08 PM

Temp was higher, humidity was higher...

Quick · 07-29-2012, 06:16 PM

My car is real sensitive to heat...I never leave the line with engine temp above 193-195 if i can help it...at 200-205 i bet i lose 40 hp and the car is a snail.I bet your best run of the day was your first run.

People with slow cars insulting JRE.

How cute.

Motion427 · 07-29-2012, 06:55 PM

Just letting you know,if you run these cars on the track,make sure that you let them cool down. The ecm is program to reduce timing if the IAT reach 86f and higher which will reduce power.
Myself I change this setting because it helps to get a more consistent time,and more power,but the tune has to be safe to accept higher IAT's. Most tuners will not touch this table for safety reason's.
so those of you that are racing in 85f weather,I'm sure the ECM is pulling timing on you.

Motion427 · 07-29-2012, 07:00 PM

The stock ECM IAT table.If the IAT reaches these temps,
At 86F your loosing 2 degrees of timing
At 95F,your loosing 3 degrees of timing
At 104F to 113F,your loosing 6 degrees of timing
At 122F to 131F,your loosing 7 degrees of timing
At 140F,your loosing 8
At 149F,your loosing 9
And at 158+,your loosing 10

Motion427 · 07-29-2012, 07:09 PM

And if you IAT's are 59F and colder,the ECM starts to add timing.

So,the best place to race is in Canada for some quick ET's.......lol......just kiding....

My supercharged Avalanche Loves the winter time here..........
