Two atmospheres are better than one
I feel like Ive heard that also. I have one out in the garage (AEM 30-2200) and I’ll open it and look at the destructions tomorrow.

Flex Fuel Sensor
Sure looks an awful lot like a regular ol’ Delphi flex fuel sensor with a fuel tech sticker.
I run that same generic GM sensor on my setup. It provides both - fuel temp and ethanol composition.
I haven’t looked at my sensor setup in a while, I wonder if the Holley systems will read temp from that. Last I recall I was only getting E content. I’ll have to double check.
So I am again having trouble with sync loss out of nowhere. The sensor was tight, didn’t appear to have moved. I can’t get a great picture of my sensor mount, but it is VERY rigid so I can’t imagine that’s the issue. I replaced the sensor with a new one, and kept it at the same .026 gap I’ve been running for a year; no change. On paper, the sensor gap is too tight, but again it runs great this way…until it doesn’t.
I do see a major difference between a composite log I saved two years ago, and the one I took today. The logger showed a square wave(?) for the crank trigger in the old log, but now it appears to be just a 1/0 type signal. Maybe my pull-up resister went bad. Any ideas?

Here is my ignition options page. I pulled up the tune from 2022, and it was the same, but I don’t trust it since I’ve had so many random changes like the injector cc’s resetting to 851cc on all 50+ tunes over 5 years.
I haven't looked at these ignition settings on mine in a long time, but here they are if it helps to compare notes. I'd say replacing the resistor is probably a good low cost troubleshooting start.
I decided to check mine today.. so in November/December my logger looked like your top one... Today it looks like the bottom one. But still runs fine, maybe it was a tunerstudio update? Kinda wierd.
That’s good to know. My laptop hasn’t seen the internet in a year, but I have definitely updated since 2022!
I spent time inspecting my crank sensor and bracket. I found a couple areas of concern, but mostly that the bracket itself can slide up/down ~.03 due to the holes themselves being slightly larger than the bolts. Gap back to .025, ignition options unchanged, and it’s back up and running.
I did a pull after fixing the cam sync, and realized only afterwards that I had loaded my spicer tune. It hooked, and it really scared me for the first time.

Lol I've done that. Forgot I had boost duty cycle higher, 60mph rolling burnouts really throw you off if you aren't expecting it.
I’ve had several, squirrelly, accidental high speed burnouts. Not a fan, but…when in doubt throttle out?
This pull for whatever reason hooked and held from 60mph on, and it was a wild ride with just a twinge of locking up all 4 on the way back down lol
I saw your post on Matts440 thread the other day, and was surprised to see you were now using Speedmaster heads; went back through your turbo thread. Are your trickflow heads repairable? I’m definitely curious to see how your build does; especially with that big cam! Speedmasters handle that much lift okay or did you swap springs? Your e85 timing is also far more aggressive than mine. I’ll be checking plug straps next time I’m at the track because I’ve likely left a lot on the table.
They should be it looks like I bent a couple of valve up near the top enough that they won't come out of the head without damaging guides. Didn't even know I did it till I was fixing something else.
Yes these heads I setup for my cam, I think I have lunati springs in them now, I had specd and measure all the stuff out for the heads like 6years ago when I first ran them.
Not on e85 anymore. Using pump 91 (West Coast swill). And 16gph worth of meth nozzle. Lol. E85 is just too big a pita to get here. I think I'm pulling 1* plus of timing per psi in the table, roughly. Either way, plugs still look ok, nothing weird yet.

Yea I’d say 20psi and 21 degrees is spicy. Remind me what fuel you’re using?
I don’t think I do. I see Subcom has LPH fuel flow data, but I don’t have that option
