The only person that knows the "why" right now is the tuner, so ask him, why.

What were your trap speeds on the 1/4 for each map?

The custom map doesn't look great to me.

Any thoughts on the log?

Going to try stage 2 on the stock DP’s.

Personally, I suggest this Stage 1 and Stage 2 map thing on this platform is garbage, in respect of using either stage map with stock primary cats.

Flash Stage 2 and log it, but there's zero reason (hardware wise) why it shouldn't be fine, imo.

Stg 1 looks clean. Load Stg 2 and see how it goes.

You trapped lower on custom than OTS? If that's the case, you're more than likely making less power on custom, which is just not right imo.

Just "blaming" a car is not the reason why he can't up the power.

Change tuners, if you're getting explanations like this!

Looking at the log, you're likely hitting the load limit but you're not logging the limiter PID, only the actual RAM Load PID. But having tuned these cars, I'm sure its a load limit.

The cause is that many tuners will set the turbo to spool much quicker which is great for 3000rpm+ hits but when you do bog pulls it will overshoot boost/load limit and then close the throttle. It's normal. However, if it is causing a drive-ability issue, the solution is to fix the WGDC in that specific area. Turn down the base duty cycle at that low of an RPM. There are a few tables that would need to be edited.

Alright new logs from above. This time MHD stage 2 on the flex map running E40. Same mods just mid pipe and plugs gapped at 22. Still stock DP’s

This first log (run 2) is definitely the worse of the two.

Any opinions?

You sure this isn't bad gas..... you shouldn't see hardly any corrections on E40.

The log I posted on 4/11/26 in this thread was on the same gas, the only difference was Stage 1 vs Stage 2. It could be bad gas though, this was Shell and I usually don’t fill up there, it was just the closest E85 at the time.

I was comparing logs with a buddy and he was seeing similar issues on MHD flex map on e40. Some of my logs looked clean like the second one I posted with almost no timing correction, while the first log had up to 4 degrees of correction. He was having the same issue some logs clean while others there were multiple corrections.

His was actually worse since he was also getting pretty bad throttle closure.

I’m going to keep logging and fill up at my usual E85 station next time to see if it makes a difference.

You need to do a couple of logs to see how it settles. It may undergo some adaptions especially on the first pull, should settle though for subsequent pulls.

I'm not sure I have seen OTS E logs before, but I know OTS 93 maps can tend to have a bit of correction. I wasn't expecting to see that with E.

Custom flex map on E44. High flow cats, single mid, front mounts, and xhp stg3.

That looks good. Im sure it pulls hard.

Hello!

First time logging the platform, BM3 OTS E30. just got done going through my ptb clutch’s bedding/settle period and it was time to hit it. I don’t have a flex fuel sensor yet but my ultimate goal is to get the sensor installed and custom tune for flexfuel as I have multiple local E85 options.

Mostly want to know if any seems out of the norm, I won’t daily an E30 OTS tune and will mostly be on 93.

Thanks all.

Bump! Wondering if anyone that has experience reading logs can read the one I posted above, thanks!

Quick look, it appears to be consistently correcting on cylinder 1. Really need a E sensor, as you have no real idea what your content is.

Thank you for taking a look, I will be getting the sensor and installing it in the coming weeks, after that it’s time for a custom tune, I will do a few pulls on the 93 OTS tune and post them here to see if there’s anything off about the “daily” tune.

UPDATE

I’m pretty sure me and my tuner found the problem being fuel quality. I would always get 93 and e85 from the same gas station i decided to go to another one all the problems went away. We’ve spent countless days trying to find the problem for it to just end up being the fuel quality I do wanna shout out my tuner spicy car works from Germany, for not leaving me stranded and not giving up on the car great dude great people, we did also switch the car from a e50 tune to a e45 tune and ended up with more out of the car with that as well.

Great news. Glad you confirmed the issue and are able to move on. Good example of how important 'good' gas is on forced induction.

Not all E is the same quality. Some stations mix such low grade gasoline with E so that the octane rating is lower than you would expect on E.

If you want the best performance, get your pump gas from a top tier fuel provider and then your pump E from a well known E station that sells high quality E such as Thorntons, Shell or Sunoco. These stations get their E from quality providers.

I see it all of the time where clients will blend with crap E and crap 93 octane thinking its the same but the cars wont handle as much timing as when running good fuels. This is also why OTS and even some pro tunes run less timing than you actually could push on E50 in these cars.

I run specific fuels to hit E50 and my car handles more timing just fine. Most tuners seem to cap out at 18-19 degrees on the S58 and OTS tunes don't typically go past 17.5 degrees.

[Sammykiller]

Got some more logs, not very long ones but doing a mix of 2nd and 3rd gear pulls on OTS 93 octane tune, car has maybe 2 gals of E85 on these pulls.

Mostly just making sure OTS isn’t doing anything out of the norm that could cause issues until I get a flex sensor and custom tune for flex fuel.

Always best to do full RPM sweep pulls.

Nothing looks untoward in the log for OTS.

Future logs, log ignition on each cylinder as well (not just corrections).

Appreciate the info, will add ignition to all logs moving forward and use manual loggin instead of the auto log so it shows more of the RPM range in each pull.
