Probably a dumb question, but does Cobb in Austin do tuning? They would be closer to me than driving to Plano for a custom tune. I tried searching this thread, but didn't really come up with anything

Plano would be your spot. Our Austin location does all of the R&D, but no custom tuning.

Unfortunately, this log doesn't tell anything. You never hit the accelerator in this log. Just making sure you know, but you need to do a 3rd gear run from around 2.5K to 6K.

I noticed that it shows like I never hit the accelerator. All 6 logs look like that. Is there something I am doing wrong?

And yes, I did a 3rd gear pull from 2.5K RPM to redline. Once the gear changed to 4th I stopped the log. What could I be doing wrong?

I think I may know what's going on ... After you confirm that you want to start logging, you have to click two more times (once on one of the datalog items (WGDC (Temp) is the top one I think?), then you have to click again for it to say "logging". I think you're actually starting the log AFTER your pull because you never started the log in the first place. I made this mistake the first time I had to log.

Sorry if the wording is a little confusing, but I hope this helps.

when you press once, it should say logging on the screen on small print, make sure it does when you start the run, then press again and make sure ti says not logging afterwards.

-timing looks good, you have drops on cylinder 4 only, log again to see whether it is consistent or not.
if it is, you can go to the drive map, or increase octane. with that said I don't think it's a big deal. keep an eye on it.


-fuel is good.

- you have some throttle closures due to overshooting your load target. by looking at your req boost abs and boost abs you can see how you're kinda over the target in three locations. Look at your throttle closures and you'll see they coincide perfectly with your overshoot.
you can correct this in ATR. it is very simple and there is a DIY on it.

PTF guys are great. However, if you really want to get the most for your money, you should tune for E85 or meth.

I won't be near my computer for a couple days to view the log (I'm on my mobile) but we will still need to know supporting mods, your map, fuel type, and ethanol % if you are indeed running it. Can't really tell you how to fix a problem without supporting information. You had said your problem was your lpfp dropping into the 40's... if you are running regular 91 or 93 octane then there is a problem there. if you are running ethanol then the % is probably just too high for your lpfp to keep up. That may answer your question.. if not I will try and take a look when I get a chance or hopefully someone will chime in.

Not sure if it made it up with all the maintenance yesterday, but those are the best logs I've ever had with stage1+FMIC today though almost empty it seems to kind of be back to how it was pre e85 mix... Does my 3 gallons of e85 dilute and become less effective as I run down my tank?

I haven't ooked at the logs yet, but as you run down the tank, E85 doesn't dilute. the ratio stays the same

No problem! Once you get the logs, I'll take a look at them for you.
