Last night I had my first opportunity of the season to run at a local 1/4 mile track (Texas Motorplex). This was my first opportunity to tune some with my new ECU+ piggyback. The lanes were busy but constantly moving so the car was pretty hot when I got to the tree.

2005 EVO SSL
3" TBE, K&N Filter, hallman MBC, ECU+
2-step deactivated
~3400 lbs with driver and gas
6 gallons 93 octane, 2 gallons 104
22 psi tapering to 20 at redline
3rd gear AFR: 11.4:1 to 10.9:1 by redline
4th gear AFR: 10.9:1 all the way
Launched at 5200 RPM

60' ... 1.807
330 ... 5.224
1/8 ... 8.074 @ 85.08 MPH
1000... 10.572
1/4 ... 12.681 @ 107.62 MPH

I need to work on my launch. It seems I also could run more boost if I had actually put more 104 in the tank... possibly lean it out some more. I was seeing near 1600 deg F on my EGTs for a split second near the end of the 1/4 mile. (EGT is tapped on the manifold 1.5 inches from block.. so it tends to read higher than others.. Zeitronix k-type thermocoupler)

damn man, nice times with just those few mods. GJ!!1

 

great time

 

very nice

 

i sure hope for you those egt temps were reading higher than they really were.

 

Nice!!1

 

I think the placement of the EGT probe and the nature of my car means it is reading high. Even when relatively stock, on stock boost I would hit 1500+ F on a pull. Timing is advancing nicely, knock voltage is below 2.2v, AFRs seem fine.. even on the rich side.

 

Nice run.
