Halfway decent E85 powerlogger file

[BEATAV8]

Finally getting some clean data! Just upgraded the valve springs to PAC 1201's set up with 147lb on the seat and 408 over the nose. The previous K motions were 125 on the seat and 345 over the nose. The change seems to have cleaned up my false knock issues pretty well. Time to turn up the boost! Thanks jpwalt and Bison for geting me thinking about it.

This pull was on straight E85 (no methanol), boost as low as I can set it.
Turbotweak SD. Fuel pressure on channel 4. Wideband LC1.

Post up some more logs when you turn up the pressure!

Glad you got it sorted out!

Sweet, congrats on finding the source of your knock.

Now we're gettin' somewhere...

27-28PSI with 11.1 AFR. 21deg timing. The 120's are at 90% @ 5750rpm. pushing the torque converter a little harder too.

The car put down a couple of decent passes today at Byron. A 10.4 @ 132mph and 10.3 @ 131.8mph. Both runs with 27-28psi and only 20deg timing. A little better than expected.

Drove it there and drove it home!

Now that's what I'm talking about!! Timeslips tell it all. How do the rpm and dutycycle logs look?

Ran up to about 90% duty out the big end. 5850RPM through the traps, 7.7% converter slip.

Those were some nice passes Steve. I knew I recognized your car at Byron that day.

thanks Dennis. Did you have the FWD monster there? So many cars that day... something like 400!

No, we broke the trans on that stupid car LOL

I had my TR there though.

 

[CGASTON]

So are you running High Z or Low z injectors

Were you in line with one of the clubs? I think I saw your car.

120lb low Z, stock ECM with drivers. A/F was 11.0, but needs to be a bit richer next time.
