I know that MHD suggested to purchase Google Play Gift Cards online however I'm only skeptical about that because there are no refund policies. Do Google Play Gift Cards work 100% of the time?
Same thing happened to me and the gift cards worked. I've never heard of an instance of them not working.

Did you have to purchase multiple cards to redeem because they're limited to $100 each?

Yes I believe that's the only way.

Could someone please take a look at these logs? (Forgot to turn traction off)

Early build N55 so decided I'd try to run E50.

FBO, Straight piped, N20 tmap, PS1, XHP s3, 1 step colder NGK gapped to .022

https://datazap.me/u/slowtrooper/e50...og=0&data=4-13

Logged right after flash. Wasn't sure if I needed to get mileage on it before logging. Engine and trans were warmed up!

Looks okay except for all of the corrections, how are you verifying your E50 mix? With the PS1, you really want a custom tune.

I'd be more concerned with the overboost. It hit 27 psi when targeting 19...bad solenoid? And yeah is that e50 verified? A lot of E85 is no where near 85%. Is this with the OTS E50 map?

I don't have any way of testing it currently but used a calculator to get a close as possible estimate on the ratio.

I am actually planning on getting a custom tune. I've been considering a stage 2 LPFP and precision raceworks coils but have been trying to do some research on if it's totally necessary and how much I'd benefit.

That's probably an issue, labeled E85 can be as low as E71. I use the Spool Performance LLC ethanol analyser, I highly recommend it.

I'm thinking I might just need a custom tune. Could it be from using OTS E50 with a PS1? I erred on the side of more E85 this fill-up (8.5g E85/7.5g 91). The PS1 has about 30k miles on it.

I really don't know what is up and I doubt it is the FMIC. Could you shed some light?

IATS at the start of the log start over 100*F. at one point during the WOT portion, the IATS got up to 188*F. so theres your problem and why the car put you into limp mode.

The log tells you whats wrong. either your IC aint up to the task, or you let the car completely heat soak before doing pulls.

I do plan on going with a custom tune, just trying to figure out if a stage 2 LPFP and precision raceworks coils are worth it/necessary before getting the tune. Any feedback on those two?

Just flashed my car with MHD Stage 2+ with burbles however I have some questions regarding the burble settings. The car does not burble in normal driving with the base burbles set to a 2s duration.

Also, how do I get the car to burble/pop on revs while in P? With the PPK it would burble on revs but now its gone. I've seen other cars with the tune revving and they do burble so I'm wondering if I've missed something. Any ideas? Thanks!

I use in oem style.
It does not seem to burbles when the oil temperature is low.

Regardless. There is a big difference between PPK and MHD burbles. The PPK burbles are much more pronounced at all levels of RPM range and load.

Still does not burble when oil is at optimal temps when revving in P.

You don't happen to have the stock exhaust, do you?
If you set the minimum speed above 0, it wouldn't activate in P.
During normal driving in D mode, I can barely hear it myself.
The sure-fire way to hear it is manually downshifting while decelerating.

Well, burble is the least of my interest when the engine is cold anyways.

It could be the steps you have taken to flash the burbles that's causing it not to work. I tried to flash my car like 3x before the burbles/pops started working again.

Not a stock exhaust. Catless dp and PE mod

The burbles worked just fine after the first flash. It just doesn't burble when revving in P anymore like the PPK did.

Current Settings Are:

Exhaust Burbles [enabled]:
Duration (base): 2s
Duration (sport) 2s
Aggressiveness: Soft
Min RPM: 1800
Min Speed: 0
Exhaust Flap Always Open on Sport [enabled]
