You have a throttle closure from too much boost. I've sent you a file a bit ago to fix that. If you can please keep your foot to the floor once you go WOT.

 

OK, thanks Randy. I didn't expect to get any reply until tomorrow. It must be true that you never sleep or take a day off!

 

I work most hours of the day and night. After 2am PST I usually sign off for a few...

 

I just emailed you 2 logs from the 'adjust1' file. Thanks!

Are you logging with ESC fully off?

 

No, fully on. I didn't even think about it. Should it be on or off?

 

It should be off. Traction control will use throttle closures to prevent wheel spin. This is bad for logging because it will skew data.

 

Ah, makes sense but even in 4th gear on dry roads?

 

Yes, even in fourth gear on dry roads. You don't want to be guessing why you're having throttle closures. Best to eliminate that possibility altogether so Randy can adjust the tune properly and not have to use guesswork.

 

I'll try to get some w/o ESC later today, Randy. It's now raining and there is sooo much traffic (and cops) here this time of year, it is pain trying to get a clean 4th gear pull.

 

Just be safe out there. The car is not running dangerously; looks fine to drive on so do this when the conditions are good for you. We just don't want to be chasing throttle closures based on traction, for example.

 

Ok, Randy, I just emailed you with 3 data logs in 4th gear and ESC off. Once again, I'll just post them as I go here too.

Wow I'm glad I read this....

 

Why's that B0bD0le?

 

Cause I been trying to do some datalogging and after almost 2 years reading this forum, this is the first time I've ever read that you need to be in sport mode or esc off...

 

Thanks for adding that. Not usually needed, but it is in this case.

 

I've been doing all my data logs with ESC on.....I'm going to turn it off from now on.

 

^^^ That would be good!

 

It's kinda of just a given for people that have done this before. For a lot of us this isn't out first rodeo.

It must be a given, if 2 major tuners write detailed instructions on how to datalog, but leave that important piece of information out.

 

I included it in my instructions.

 

Where are those instructions? The 2 (focusst.net) instructions I read from you do not include that...

 

Surrrree just happens to be 2 days ago it was changed. Lol.

 

I had a stickied thread for about a year, but it got deleted a while ago. So remade this.

You know now, in any case!

 

The fswerksvp one is still there but yeah true that, better late than never.

 

So apparently the factory pre-load on my wastegate is not consistent with the majority of ST's.

Randy's been working hard and I appreciate his attention to detail!

 

I got your email and will look over the info in just a bit here.

Testing against the Cobb files is a good test, as we did, and helps to troubleshoot. My guess is the preload, but it looks like we have it sorted now. I'll be in touch!

 

Ign. Corr across the cylinders of 0 or positive numbers is generally a sign of good fuel right, during WOT?

A positive Ign. Timing is good too?

What should STFT be at, positive?

Thanks all.

 

Ign Corr of 0 and greater is good/safe. Ign Timing can be negative and that's not a problem. You will see that at low RPMs and high load in some cases and that is OK. Most of the time, though, Ign Timing will be positive.

STFTs, ideally, you want to have them in the single digits, but you also have to add in the LTFTs, if any, for the final amount.

Are you still seeing negative values for Ign Corr with that Cobb OTS file? Email me if needed, I can't recall right now... I need to go back and read the last email again. Looking at the log for the Cobb OTS I saw a good amount of correction, but I think we spoke after that...

 

We spoke after the crappy gas data logs, I put it back to Stage 0, got the crap out then put Shell 93 in. I just sent you a 91 octane Cobb OTS (just to be safe w/ the fuel) but it was in 3rd gear (much traffic).

Hopefully, the info you need is there, I can go back and load the 93 octane and do a 4th pull, late tonight maybe. Thanks!
