Sorry I couldn't make it this weekend, had something come up. From the pics it looked like a good time, wish I had made it.

Jason. looks like everything is running fine as far as the wastegate goes. What do you have in mind. I'm down for trying anything to spool faster. Right now I'm trying to figure out the whole fuel mapping and latencies thing. I haven't changed anything but I'm studying up. Got a question for you. I'm dumping a ton of fuel during idle after I stop ( i.e. stop light or pulling into a parking spot), it evens out after awhile but is there anything I can do to lean it out a little during that time or is this fine. I know it's better to run rich than lean but it's getting so much that it's almost choking out? Like I said I'm still learning this whole thing so any help will be nice.

As far as your fuel stumbling... could be a small vacuum leak, could be the injectors need some cleaner or racegas ran thru them, could be the scaling is just a bit off. Youd have to log your fuel trims so i can check them out.
I just wanted to see how much tension is on the arm of the wastegate, may help with spiking sooner... seemed to make a difference with the green this weekend. Especially from before and after. He also switched to the stock actuator instead of the high pressure which doesnt effect you because you are on the Forge now. It really comes down to i need some seat time with the car to see if i can help it with a few things.

Also change my injector scaling to 790 seems to be running better, however I did a 4th gear pull to 7000 and had some knock starting @ 4500. About 7 counts.
Fuel trim as of a couple minutes ago. Scaling @ 790. Have not touched the latency values.
Idle
-Low -3
-Mid 0
-High 0
Cruise
-Low 0
-Mid -1
-High 0
I assume this is good from what I'm reading or am I reading things wrong?
Jason in this situation what should I do to get rid of the knock. I'll try and send you my logs. Need your email addy.

Can you run me through that process? I have no clue how to send my logs through email. HELP!

check your AFR's at that point... If i remember right, from your graph 4500 is almost peak for you or just after peak boost correct ? you should be seeing about 11.3 to 11.5 there... if its leaner then that, add a bit of fuel, probably .2 or so and see what happens. I wouldnt pull too much timing there because you arent really running too much. Id imagine you are just a bit lean, either there, or at the 4k mark.

4000-11.4
4500-11.0
5000-10.9
5500/6000-10.7
6500/7000-10.6
On my fuel map 260 load I'm at
4000&4500 - 9.5
5000 - 9.4
5500 - 9.6
6000 - 9.7
6500 - 10.0
7000 - 10.1
260 load and 4000 thru 7000 I had knock. 7 counts dropping to 5. I'm running rich so I have no clue what to do. More fuel or less timing? Any suggestions?
Jason PM me your email addy and I'll send you some logs.
