I think I finally have everything dialed in with almost no knock on pump gas. To add timing, do I start at 750 rpm range by tracking datalog?

Thanks!

Here is a good basic write-up on what you want to do:

Look down the page at the WOT tuning section and that should help you get dialed in pretty well.

Good luck!

Thanks, Twistaye! I have read that thread. My question is do I increase timing table starting at 750 rpms?

I would start adding around 3000, depending on the setup. You can use the timing tab and add 2* across the board above that then log a pull and analyze the results. Add 1-2 more as you creep up on max timing. On gas you are going to be limited to 9-12* max before knock comes in as a general rule. I am 10:1 and on gas I was limited to right around there. On E, it can be considerably more.
You may be able to add some at a lower rpm too, you're just gonna have to play and see what it likes and what it doesn't. In the end, you will build the added timing into your timing map.

Thanks, Marty! I'll start by adding 1 across the board and see how she likes it. If you open my log, I'm at 15* at the end of my pull. She feels good!

Now SOMETIMES, you will need to pull timing and that can be done on your timing tab also. I like playing with mine and tuning with my butt, .
My son usually rides shotgun and does my timing adjustments on the fly and fueling needs on the fly also. Makes it fun and easier for me. Grab a friend and go drive while playing with it.
I am on my phone currently so I can't view the log but BOY DO I WISH THAT WAS POSSIBLE....(Hint Thomas/Dave at EcmTuning.)

That sounds like some fun family bonding to me. hah I did pull a couple of degrees up top. Time to play with some timing

I looked at your log, not logging boost???
Timing looked good and smooth, no knock. Is your upper rpm limit just 5500 right now? Ease on up in the rpms while logging, at 500 rpm increments, adjusting fuel and timing. The motor should whirl on up to 6500-7000. Get there in small jumps so you don't hurt anything! Remember, you can't tune what you don't log. When I first pushed the limits of my car, it was a teeth gritting experience all the way up to 9200, but you won't need to go that far!

I will and thanks!! It does log boost on my end. Plan on controlling boost via link in the future. It was raining cat dogs and pigs. Couldn’t get to 7k on the roads I usually use.

Gotcha. Not condoning it either. Smart man. I have a place I can tune safely so I am lucky I know the guys at the airport
Yeah I couldn't see boost on my side for some reason.

A free personal tuner in passengers seat and an airport?!? I’m envious of you

Bahahaha.....yeah its alot of fun and good learning experience for up and coming mechanics that will need to understand all the parameters the computer looks at for proper control of the engine. You just can't teach that so I have my son with me most of the time for experience purposes AND advice.
He graduated from Tech class but they don't get anywhere close to things like we do! And I am blessed to have this opportunity in life!

That’s great! Don’t forget about the bonding factor too.

Log looks pretty solid. Your WB factor seems to take a dip around 3-4k RPM. Other than that, not bad. How much boost?

Thanks, Joe! 19 in the log. Turning it up to 20 my next time out. Then adding timing as long as there's no knock.

I wonder why you can't see boost. One or two more pull and MAF should be solid.

Try taking boost out of the captured values and then put it back in and have it displayed. Just a test.

Ill try that. Thanks Marty!!

I turned it up a little too much, 21, but now get some knock. Think I'll lower it back to 19. Can you see boost now?

I can look when I get home, about 3 hours or so.
Glad to see you aren't afraid to "play", I enjoy it. You are doing the right thing, don't run her on the edge.
How does she feel with a few more degree's of timing? Noticeable or not?

Thanks, Marty! I haven't added timing since I got some knock at the end of the last pull. Want to turn boost down back to 19 and I'll add timing and post another log.

I can't see boost or wideband reading on my end. Pull a degree after 6500 and it may need a little more fuel, but I can't see that part on this end. We may have different versions. I'm glad I got on the tuning computer because the power supply isn't working and I am going to need this soon I hope!

That’s so weird. Hits 21.X and I did notice injduty was getting high so I will prob end up needing bigger injectors next so I’m turning the air down haha. But before I do that, I really need to change timing components and either refresh the head or go with a 2g head. Stuff adds up soooo fast. I need to hit the lottery.

Yeah, just building my head is mucho denero and I hope it JUST 16 BENT VALVES . Gotta laugh or I'd cry.

I would definitely cry first though haha
