Was determined to get a streetable 26psi map setup on my bone stock 05 evo. 26psi is what I get at 100% in the boost table but it took an obd2 data logger to tell me when I had enough timing retard to not trigger the knock sensor and have the factory computer add fuel. Wasn't about to run 26psi without the knock sensor at max sensitivity. My ignition timing map now peaks at -5.9 degrees at 6k rpm and about -4 at 3k rpm.
Really aren't losing power by retarding timing this much because less advance is required (flame speed increases) with increasing cylinder pressure. gtech meter confirms best horsepower is with big boost and retarded timing. The next part was to get my A/F gauge off the peg at under 10:1. I had to go into the software and change the settings to +/- 40% on the MAF map and I'm now running minus 37 fuel at 6k rpm full throttle to get 10.5 A/F. About -20 fuel at 3k rpm.
Took a couple hours to sneak up on this scary fuel setting but EGT's and A/F are where they should be throughout the throttle/rpm curves. I've since extrapolated and tuned ignition/fuel/boost maps for a 16psi max boost map for commuting. It's got nice tip-in and is very linear. I've also created a couple maps at inbetween boost levels and I scale the total maps by the difference in boost level. All the variables scale really well and give good A/F's at all throttle/rpm values. I've got about 30 hours tuning in these maps and will email them to anyone interested in trying. The factory knock sensor is very sensitive and conservative but I strongly suggest a good A/F and EGT gauge before tweaking the car this much.

 

wow, 26psi on 93 octane?

slap it on a dyno for some numbers....

 

I would love to see this map.

 

let me know your email and I'll be glad to send it to you. You can post it or email me at sv900@hotmail.com

Sent email on Wednesday. Did you receive it?

 

Where in Nova do you live? I would love to meet you. I have an xede as well with 3071

Thanks

 

Got up early (6:00 arghh!) and out on the roads this morning to fine tune part throttle response at the 1% level. Very noticeable difference in roll on acceleration. Particularly in the short gears where there's less time to respond, exede doesn't like jumps between cells. Helps to roll on the throttle also instead of dumping it. I found it particularly useful to go to 0 theta and 90 phi on the fuel graph. In a progressive map like mine that goes negative from the lower left cells to the upper right cells, you can see every throttle row and how it progresses through the rpm range.
