Re: Newb tuning questions.
Any reason why you want to keep using BlueBerry cal?
Re: Newb tuning questions.
boost button, sorry for any confusion.
Re: Newb tuning questions.
FullThrottle is the table.
Are you burning a chip or using ostrich?
Re: Newb tuning questions.
If you are running +40's, set the injector size to 58 lbs. Does AFR stay the same while in boost, or does it get richer or leaner as rpm increases?
Re: Newb tuning questions.
I am using a flashable boost button smec. the air fuels drop to about 13:1 range and stay steady until about 15-17psi then it goes way lean. im running 75lb hour injectors and I scaled the cal down to 55lb without any real change.
Re: Newb tuning questions.
I would back that boost off until you get your fueling to actually respond to changes you make in your cal.

I agree with ondonti turn your boost way down until you get the fuel right. YOu don't want to put a hole in a piston.
Give us your specs, engine size, injectors size, etc. Any codes? sounds like it may be scaled for bigger injectors than you have, thus giving you less fuel. Also if it is a 2.2 cal on a 2.5, etc. How much of a newB are you? that will give us an idea of where to start to help you.
Also it is possible that you are changing the tables but then not saving and Re-compiling the file to get the new updated .bin file, thus continually burning/flashing the same unchanged .bin to the computer
Have you seen this? https://www.youtube.com/watch?v=RBnf2fsL10I I am no pro but this give a good start. I assume you know most of that already as you are changing stuff, but maybe missing a step somewhere
Re: Newb tuning questions.
I would run a vacuum/boost line directly to the wastegate, this will give you minimum boost level (usually 6ish psi on a stock turbo/can) and is a good spot to start tuning from. Or if you have a EBC, turn it all the way down. Once the AFR is right at this level, then turn it up a couple psi at a time and adjust accordingly.
What fuel pressure are you running?
Re: Newb tuning questions.
Doesn't sounds like the changes of the calibration is making its way to the ECU.
Can you verify what you have the ECU to the calibration you changed?

I think you got it. I have been saving the file but not compiling it. ( doh) That would explain why my changed didn't make a difference.
Also, I turned boost down as much as possible. no pre load on the arm, line directly to gate, ect. but im still running the stock he341 wastegate can, so minimum is 17psi. I was going to put helper puller springs on the arm if I couldn't get this figured out today.
Re: Newb tuning questions.
so that's what the problem was. I have successfully tuned the car on 17psi, 93 octane, no knock. Feels amazing, 11.7afr across the board. Gonna fine tune a little bit of the drivability stuff then start on the e85 tune. thank you 1badvan for the youtube link. it was very helpful!

That video was very informative. A few more of those and I wouldn't look completly stupid when asking questions.

I vote to either make it a sticky or put it in the knowledge center. I swear that I search before asking but there either threads with 40+ pages that take awhile to dig through or not direct answers in the shorter ones. Since I didn't know that compiling them was the issue, I didn't know what to search. Thanks everyone for their input and suggestions. they are very much appreciated!
Re: Newb tuning questions.
A few videos like this and most of the newb questions would be cleared up. I'm getting a flashable smec here soon and will be asking a lot of questions I'm sure. A few of these would make it a lot better

Cool! Can you send me a copy of that cal then? :D I was kinda wondering what you had changed when I looked at that other one this morning, pumping efficiency was still stock lol.
Re: Newb tuning questions.
Ill try to send these tomorrow, i still need to add to the pumping tables. I also changed the part throttle and wot tables to command a richer mixture, esp up top. still need to add more.

Glad you figured it out, it's always frustrating to get stuck on a car project.
Re: Newb tuning questions.
I'd like some more info on what to do for part throttle fuel and such. Still have boost there too is it just more of the same
