Question for Tuned L99 owners...

[Fireslayer]

Revo,

What kind of tune do you have and with what software?

Well, I've been so busy with work that I didn't really have the time to mess with it. Then the temperature dropped from 90+ to where it is now (@50-60 degrees). Now this thing is a freaking monster! It's almost uncontrollable...almost

I'm not just talking about the summer tires losing traction. There is a huge 'seat in the pants' difference here! I loaded the stock tune to see if I could tell a difference between Ted's tune and I definitely can. It seems like this car loses a lot of power in 83+ degree weather. That may be why only southerners are complaining.

Ted, I apologize for the negative feedback on your tune...looks like it's just the car in the summer.

JRE tune, via SCT. Car feels very strong otherwise.

Once you get above 80* on the intake air temp, the ecm will start pulling timing, and it makes a ton of difference. Ted may or may not de-sensatize this table, but that would explain a lot in relation to performance vs. ambient temperature.

Actually on the stock tune, its starts to pull timing at 86 degrees. On a normal summer day, You hit 86 degrees within seconds of stopping at a light.

I reduce some entry numbers on that table, but Ive seen other tuners that dont.

If you want better performance off a stop light, you can do some reduction on that table.

Well I said over 80 because the table blends that first block at 86* with the previous block that is all 0's when it its in between those two. But yes you are correcto! lol. I desensatize the first 3 rows or so, I also desensatize the rows up above the zeros that ADD timing when below 50* iat (dunno exact, not at laptop to look at a file). I've found that in cold climates, once you have timing dialed in and they get that freak cool weather, then you have too much.
