EU and dyno tune #s

*jmeister* · 03-23-2007, 03:38 PM

First off mod list: shortram & pop charger, 00VI & DEK injectors, UDP, warpspeed ypipe, no cat, resonated catback, apexi ws2 exhaust

I don't think there is any smoothing or correction factors figured on this.

Blue line is the base pull and was rich as ****, around 10.5 from 4200 to redline. Red was best pull and green was heatsoak both with AFR was around 13.0-12.8:1 we saw no more gains by leaning it out and since timing is advanced 7 degrees we decided not to push it. 7 degrees was the max timing advance & also saw no further gains by adding more timing. Tried raising the revlimit but had trouble figuring it out so I decided to mess with it myself sometime and not burn anymore dyno time... watch for seperate post with settings file and datalog pics.

Nice gains... looks like about ~25 tq/hp or actually a bit more peak and that's not a dynojet either.

How does the car feel now? Where are you opening the VIAS?

*jmeister* · 03-23-2007, 04:42 PM

Car is responsive as all get out. VIAS is 5150, looks like I may have some room to play with there
Yeah they're not big fans of dynojet numbers, which would be roughly 15% higher IIRC

Very imimpressive gains. Not sure what you meant by this

Since the lean AF has nothing to do w/ timing in this situation (EU in use, no need for raw AFR adding fuel/taking out for timing etc

). More so a situation of being closer to stoich. What octane did you use when dynoing?

*jmeister* · 03-23-2007, 07:11 PM

Well we didn't want to lean it out anymore with the timing being advance. At least as I understood him explain it. Then again I'm not sure what you're getting at either.
93 octane always

Nice numbers. Are you auto or manual?

*jmeister* · 03-24-2007, 10:03 AM

5spd on stock 94k mile clutch
Heading to the track tomorrow so we'll see what it all means then

*NmexMAX* · 03-24-2007, 03:47 PM

Any header plans?

shew, I'm having a hard time justifying the cost per HP increase for headers. Clutch is next
