My First Tune - Looking for Input - EvoXForums.com

Here's a random run from earlier today. I know I'm a little rich, and the boost curve still needs a little cleanup, but I wanted to post a log to see where you guys see room for improvement. I'm open to any suggestions.

2008 GSR
high flow cat
cat back exhaust
ETS intake
UICP
3-port

337 hp 324 lbft

It was about 55-60 degrees out for both runs, so I changed the SAE correction.

Looks decent to start with... you can lean it out a bit all the way from 3250- 7500 rpm.. maybe about .3 afr.... Boost curve looks good other then the slight dip at 4600 rpm.

bobby.is.rad · 04-06-2012, 07:47 PM

I've leaned it out since then, cleaned up the boost, and gotten more aggressive with the timing. Here's a run from yesterday.

HappyMint · 04-06-2012, 07:54 PM

Your power curve is not very smooth, make sure your timing map is smoothed out and isn't blocky. If it is, then you'll often see that type of bumpy curve in VD.

This could also be attributed to a non-flat surface. Unfortunately obviously we can't tell what surface you were on.

bobby.is.rad · 04-06-2012, 08:16 PM

Are you talking about the first VD or the second VD? The first VD only had smoothing set to 1. Could that have been it? My second VD post has smoothing set to 2 and looks a lot better. I think people usually have their smoothing turned up when they post VD sheets. Sometimes you can fudge a few extra HP out with a lot of smoothing.

Now it is.. in the first log he posted it was down to 10.7/8 up top..

OP: If it was my car I would add a tad more fuel to the 3-3500 areas since ur at peak boost and AFR is high 12's in your log.

Kooldino · 04-06-2012, 09:05 PM

Lean out the fuel past 5500, add more bcs around 4000-4500 to smooth out your boost curve.
