A bit of knock when you floor it and at 6.7k. AM is not getting to 1 unless this log is soon after start. I`m no expert, just looking

About 20-25 min driving from an overnight cold start. Held at .97 for 5 or so minutes. Not sure how long it typically takes to hit 1 in ideal situations.

Checked mine today goes from 0.7 to 1.0 in 8-9 minutes in 25c weather.

it doesnt go to 1 because ecu is frequently correcting
it's not worrying but would definitely benefit from a maf scaling and come base timing correction

Good to know.

I don't know enough to make changes my self.

I saw the MAF rescale thread. Looks like I need to do se research.

Hey, so I did a test run/data log. I have a completely catless exhaust, and factory intake with an aftermarket drop-in filter. Today I grabbed 2 data log files and exported them as .csv files. Is there a preferred method to upload the files to this thread for review/discussion? I'm really curious to learn more about tuning..

Thanks in advance!

datazap is commonly used. Easily displays everything

Start here. In fact it is a good idea to look through the links in steve99's sig.

I had @tomm.brz do some custom tuning for me after reviewing logs on my V4 tune. Big difference in the butt dyno through mid range, and no more knocking or AFR issues from V4.03. IAM hits 1 quickly.

Flashed back to V4 tune to make sure I wasn't imaging things. Thanks again Tomm, nice little Christmas present getting the car dialed.

Are you actually running more timing now than with the catless headers?

Yeah up to 10 degrees more at the top end, but I was on 93 octane (east coast) with the catless headers and have been on E85 with the 2013 and 2017 OEM headers.

Any power advantage? And I thought the exhaust was entirely different from +17 red plenum engines.
