That's awesome Kyle! 1.88 60's are awesome for an EC 4.8. So when do you actually turn off the commanded timing and AFR? While rolling around the water box or right on the line? I don't think I'm coordinated enough to do that. I think I'm just going to bench race until Harlan's new 2 step with the built in timing retard comes out. Stalling a 2400rpm converter to 3300 is amazing, it just shows how much more torque you're making now right off the line.

 

I turn it off when I am next inline at the staging lanes. Not to hard, just have to click 2 little boxes and start the log. Then the laptop is just along for the ride. EFILives is supposed to have bidirectional control sometime in there new V2 that coming out in a couple of week, so I'm anxious to play with that.

BTW Todd, you never answered my question in the FI section on Tech about your IAT's with the intercooler setup you running though the heater core.

 

what about wraping the exhuast pipe does that help?

 

I totally forgot about that thread. I assumed it was just done due to the fact that a truck guy replied to one of their threads. Usually when a truck guy chimes in over there, amidst the sea of f-body owners, they crap themselves and nobody replies or comments.

I'll reply to your post over there.

 

Yes wraping does help, and I believe his pipes were wraped at the time of his findings. I have no first hand experience with wrapping, because I have to go through emissions this month. If they see wrap on my pipes, then the 18 year old dork working there that doesn't know a PCV valve from a carburetor will have a brain-aneurism and fail me.

 

Yep, I do have my pipes wrapped. It does make a noticeable difference

 

What headers do you have?

 

I have the stock manifolds.

 

Were you using your meth on those runs? I'm wondering if there's anyway to fatten up the meth on the starting line to help spool the turbo as well. Hmm...

 

I was going to post a thread in the tunning section about this.....
I was able the brake stall to almost 2600rpm and build 8 psi at the light with a bone stock 4l80e converter......
I use the P.E mode for my "stall" fueling. and drop it down to 1.0 after my "stall" speed has been reached..... You can pull timming to help "load" the engine, but at the track my truck kept doing the F8L launch hop, so I didn't try that yet.
