New guy looking for some advice

[ABrock]

Brand new here, I've only read through the forum a couple times but I wondered if someone would be kind enough to help me with some tuning?

I have an 07 si mostly stock running 91 octane. Only thing not stock is it doesn't have a cat on it and a different clutch. I bought my flashpro recently and have been running the stock tune it comes with, with only slight changes to it. Basically disabled the secondary 02 sensor and lowered redline back to stock because I don't trust myself.

Anyways I did a short drive today just playing with datalogging for the first time and I thought my results were really weird. I know its not ideal data and my driving was pretty bad but I wasn't trying to be easy on it either or planning to use this.

Could someone who knows more then me take a quick look and see what they have to say about it? It would be much appreciated

Overall it doesn't look too bad. It's got some knock that should be addressed, and the WOT fueling is lean. I wouldn't recommend doing any more full throttle pulls until you get it cleaned up. I can help you with if you want, there are a few more things I would recommend doing like cam angle adjustments and among others.

Are you planning on adding an intake or exhaust any time soon, or are you keeping just the cat delete for a while?

[ABrock]

Yeah I could probably use some help I don't know what i'm doing. Ive been trying to watch youtube videos and learn more about tuning in general. The knock concerned me and I suspected it was running lean.

I would like to do a full exhaust and a new intake but having just spent quite a bit on the tuner itself I will probably hold off for a few months on that much.

[EFICU]

Okay sounds good. Can you post the calibration are running on so I can see what changes you made, or want to make? I would also like to use the MAF scale from the calibration you're running since it's pretty good for part throttle driving, then I will transfer it to my file to get you started. That and so I can see what rev limit you want too, unless you want to go 8600 which is the max safe rpm for these.

Since you plan to upgrade some parts in the somewhat near future, I would recommend using a completed file and make adjustments to that for your car. When you upgrade the intake and exhaust in the future, it should be tuned by locking each cam angle individually so you can tune each one then blend it all out. That way you can take advantage of those parts. With just a cat delete, you don't need too much done, We can tweak some things to where you can have a lot of fun with it for now, then when you upgrade the intake and exhaust really fine tune everything.

If possible, go ahead and post your calibration on here like you did your datalog, then I can put together the first file for you.

Would it be recommended that I use 93 octane? It is no big deal for me to switch to that I just never have.

[EFICU]

Totally up to you on the octane. If 93 is readily available and you can get it anywhere on a road trip, go ahead. If you think there might be problems finding 93 somewhere you would drive the car, I would leave it tuned on 91. So it's up to you, but let me know what you would like to do. If we do tune it for 93, and all you can get is 91 in the future, then I tell guys to put enough 91 in to get you somewhere you know there is 93. So, if three gallons would get you back to town where you know there is 93, do that, then fill up with 93. Or if you're on a road trip, and all you can get it 91, just don't drive with heavy load on the engine as much as possible and don't do WOT pulls. I don't run the ignition on the ragged edge anyways, so it's not as serious as I may be making it sound, I'm just protective over your cars and don't want you guys to run into issues.

So here is the first one for you. I transferred your rev limits and the MAF scale to get us started. Take it for a drive like you did on the last datalog and we'll see how it looks. Make the datalogs between 20-30 minutes like you did, with as much stop and go type driving as possible. Then do one wide open throttle (WOT) pull in third gear from 2500-8300. Then we'll see how it looks. It will take a few revisions to get it dialed, but it should be pretty close on this first one, and the knock should be gone. Don't get too wild on this first drive, just normal driving and the one WOT pull until I can clean up any big chunks. Then you can get after it in the next one.

What type of cat delete does it have? Is it a race header, or just a cat delete pipe with the stock exhaust manifold?

Thank you very much I will make a log as soon as I can. I will stick with 91 octane for the foreseeable future. As for the cat it is stock header with a diy test pipe welded in place of the cat. I researched exhaust headers and found them to be absurdly expensive for a project as low caliber as mine.

Sounds good. Yeah they are a bit pricey, but the main thing is getting the cat out of the stream. That is the most restrictive piece to the entire puzzle. The header does make a good bit of difference, but it's not for everyone.

We'll see how it looks when you post the datalog.

[ABrock]

Got a log from my drive today. Thank you again for helping me out

Can you double check the datalog on your end, it appears you turned it on and then right back off while datalogging. It's a very small file, guessing maybe only like 4 seconds long. Let me know what you find.

Oh that's weird. I will check it very soon

[ABrock]

I will try uploading the same file again. It looks fine on my end and is just under 25 minutes

[EFICU]

Unfortunately it still won't load with any data. The datalog is 682kb, other datalogs are like 6mbs.

When you open the datalog in your FP manager, make sure that the "compress datalog" box isn't checked when the file naming box opens up. It's just below the bar where you name the file. If the "compress datalog" box is checked, uncheck it and resave the datalog. Or, under the calibration tab of your file is my email address, you can try to email it to me and see if that helps. But let me know either way. There is one more tab that allows for compressed datalogs, but let me know if the "compress datalog" box is check when you click save to save the datalog.

Okay hopefully this datalog went better. I just recorded a whole new one today and it was too large to send after I turned off compression. I compressed this file let me know if you can open it or Ill have to find a different way of sending it

[EFICU]

Yeah that one came through. The part throttle trims look pretty good. Unfortunately, it looks like the primary o2 sensor has failed or is failing based on the WOT AFR data. Since you have a custom cat delete, is the primary o2 sensor in the same position or did you relocate it? I noticed the AFR reading was a little strange in the original datalog you posted, but it seems as though it is failing. Is the primary o2 sensor OEM or aftermarket?
