Hi..

I decided to go back to 93 octane at the track and fine tune a map to provide best performance. So far, I have been able to tune this map to provide results close or better than what I was getting with 100 octane race fuel. Key point: I think I have a very good 93 octane map now.

I want to use the 93 octane map as a base to create a 100 octane map. My idea is to:

• Add 1 degree of timing to all three dynamic maps (BTW, I did the copy thing so all three maps have the same values now). NOTE: only add this above 3600RPM
• Add 1 degree of timing to the primary ignition (above 3600 RPM)
• Adjust my AFR to 11.9 ~ 12 to 1

I have attached a data log from a 4th gear pull using my 93 octane map for reference.

I would like to know your opinions about my tactic to create the 100 octane map.

Thanks,

Jeff B

If you could attach your actual ST map, I could have a better look at your settings and more of an opinion. According to your datalog, it looks pretty healthy and nice linear values accross the board. As for your tatic on creating the 100 oct. map, that seems reasonable to me. Start with that and then datalog and tweak from there. Your could probably run a little more timing maybe and jack up the boost as well. If you dont want to post your map, is there anyway you could send it to me. I'd like to see how your map compares to my 93 oct. map since I just can't seem to get the timing values right in the mid rpm ranges. Thanks!

No problem sharing the map... how about this... if I show you mine, you show me yours? :-)

I attached both the base and real time... don't know if you read my other post: How to get dynamic "C" to save as real time??? Read about the procedure I am using to get the "C" map to save and you will understand what is going on...

Catch u later

Wow. You have no fear of boost 22psi around peak VE (4000rpms). I'm too askeered to run something like that. 90% WGDC around 5000rpms to milk the turbo for all it has. Vroom Vroom

Overall, I don't notice anything 'bad' about your log. I haven't looked at the map, but the log looks relatively healthy (except I am askeered of that much boost around peak VE). No wideband data so I don't know how the fueling is. The ignition timing looks pretty standard. You might want to try to get rid of that dip to 18. Try to hold it at 19 if you can.

As far as your approach for the 100oct. Seems fine to me - HOWEVER, I have yet to tune for higher octane so what do I know

Yea, that high boost made me a bit worried too at first but my understanding is many of the "pro tunes" are trying to hit that target.

Here is a log from one of my last actual 1/4 mile passes using the 93 octane map, the fueling is logged here (timing was a bit off still, am working to get the values up to 19 like you noted)

Wow, your numbers are crazy high in the target boost and WGDC high tables. It may be time for me to grow a pair and pump it up too, ROFL. RU running a helper spring with this map if so 19 or 11lbs, I have both sitting in my glove box right now ? and this is 93 oct right? I am comparing our maps right now, i'll post mine, once I'm done!

Yea, that is the 93 octane map... what is you best ET & MPH in the 1/4? I thought I read that you ran a 12.8 @ 106? If so, what fuel & map did u use for that pass?

I am running the helper spring... think it is the 11 lbs. (home depot # SP-9618). Honestly speaking, I believe I installed that spring before understanding the relationship between low and high WGDC relating to the control of boost. I think I could remove the spring and work with the WGDC's to get the same boost I have now. The only reason I don't take it out tonight is I don't want to take the time to "tune" the WGDC's again. A friend of mine (overdose) is not running a spring, his boost is pretty much the same as mine and he is running quicker and faster in the 1/4 !

Don't forget to post your map, I want to check it out...

Thanks

I actually ran a 12.89 @ 105 before I got ST, with the Cobb OTS map . That was with an almost perfect reaction time and a low 1.7 60' time. I have not been to the track since I have gotten ST nor even this season. I am getting Protuned this Sat. and for the baseline I think I am going to run a mixture of my map and yours. I see that you added 313 to your closed loop delay, what was that for? As for the helper spring, I think you have the 19 lbs. (or the 9.5 cant remember which one is which, I have all three to test out) spring the 11 lbs. spring is SP-9608. I thought that with a spring you tune down the WGDC, and with my map right now, I am able to hit almost identical boost numbers a bit lower VE boost around 19 tapered to a solid 15 at redline using 70-75-82-85 WGDC. I havent messed around will fuel too much yet since my wideband is not here yet. I just used the values or 11.4-11.9 from 3200-6800 rpms. As for timing, I only adjusted the KC tables and didnt touch the primary table, which is probably why my timing numbers are all over the place in some places and loads. I am trying to upload my maps now, stay posted.

Here's my map. It's pretty much just a tweaked version of Wolfplayers rescaled stage2 map.

HI..

I got some GT100 on the way into town this afternoon. I tried the map that leaned the fuel and added 1 degree to pri ign. and 1 to each dynamic advance maps.

It took all of this timing so I started tuning,,, end result is I got 4 degrees more advance through pretty much all of the RPM range 3K to redline.

I need to study the logs a bit more but here are three of them (two 4th gear pulls, one with 93 the other with 100 and one run 1st through part of 4th gear blast)

If it doesn't rain tomorrow, I will try the map at the dragstrip.

Hey TurboQueef, heres an update, on that map I listed above and your fuel map with a little richer at peak torque, I put down 307 awhp and 328 awtq. After the tune I was able to get 316 and 348 out of it. My advice on your tune is to set all your KC maps to the same value (anywhere from 6-9) at the upper loads and tweak your primary ignition table to get achieved timing. Look at your logs and where ever your KC isn't that value you loaded (6-9) reduce your PI table until it is. Shoot for around 18 @3000, 20 @4000, 22-23 @5000, 26-27 @6000, and about 30 @ redline. These were the values that got me the best results. Also with the fuel table I was using, it was running a bit rich at peak torque so your table should do just fine. On 107 oct. to achieve best results WGDC tables were set to 100 and 70-80 with timing set to around 34 at redline so about 3-4 degrees in each area of the PI table. Didn't touch the fuel table and was hitting nice A/F ratio in the upper 11's. My car wasn't wanting to produce boost even with the tables set at 100% I was only hitting 20psi for a brief second and tapering to 14.7 at redline. This was probably due to the extreme heat we were in (99+) and the car had already had about 10 pulls on the dyno. Your tables will be different of course since you are using the helper spring. I may need to try that or get a new boost solinoid since on the logs it showed my car wouldn't produce more than 90.2% WGDC even with the solinoid unplugged so the WG was maxed out. And one last thing about you PI table, you should smooth it out at lower loads where you decreased the timing to 20 keep it at 40 and change your closed loop delay from 313 to 0. My 107 map rocks and the car feels way quicker on it than the 93 map

*Edit from last post, looking at your log your timing looks pretty good, you could try and get 1 more degree at redline, and the only other thing I think you should do it lean out your map from 3k to 5k. You should shoot for around 11.8+ to redline depending on the gas you are using. I was at 11.9:1~12:1 from 3k to redline with a 50/50 mix on shell 93 and torco 107 (race gas not the concentrate). Now I need to get some boost numbers like yours and I'll be good to go, lol. Are you using the same boost map as before?

Just wondering if anyone can convert to 2004 map? Would be much appreciated!

You need a Protuner to do that.
