MS3-Basic has a lot of sensor Out of Range that flashes CEL codes. The Knock Warning is a separate output. With or without a warning output, if the knock threshold at a given RPM is crossed, then timing is pulled. If still knocking, more timing is pulled. Some of the details are programable (as in keep timing pulled until... vs run right at knock limit).
If there is a way to tie it into CEL, I'm not aware. My plan is to drive a separate LED. If I can simple send it to CEL, and also keep the other functionality, please tell me how.

I'm running Wiseco pistons in my personal car with a clearance of 0.0035. For 400whp and below, I use 0.0035.
For reference I have zero audible piston slap during a cold start. Just recently had the engine apart and the dry lube on the Wiseco piston skirt is still in tact after 7k on this setup.
This being said, at .004 I don't think you're in danger of any noteworthy accelerated wear.

The last round, machine shop said I didn't HAVE to hone, but there was some visible up down stuff, and substantially less but was still was after hone, but nothing you could feel with your finger. I was concerned with the number of hones the bores had but the machine shop said there was no reason to get bigger pistons and even with the last hone it was still good.

I was going to "trim the fat" and delete the BS footage but the sound was nice so I left it in. That high pitched spooling is actually in vacuum. I use an auto meter boost gauge and once I hit 5hg the sound instantly shuts down and turns into a more whooshy sound.

The other problem with doing a 5th gear run is that because its mistaking the operating noise for knock and pulling timing, top of 5th turns into a add>remove>add>remove>add>remove timing deal and the car breaks up a good bit. I'm probably not going to see my tuner until the spring for this issue since I won't be driving the car much more from now until spring, and certainly not going that fast.
One more thing to consider with the wheelspin, I am on 225 Ventus RS3 tires that have under 10k miles and great tread, but they're ~3 years old and have been through the process of warm and cold weather. I hear that this process changes the compound of the tire and causes it to become permanently harder to some degree. I'll need new tires soon

Maybe I should just stop posting videos lol. I am happy there are now videos aside from Soviet's on youtube of the EFR in a Miata. I'd love to see some similar vids of his 29psi E85 setup.
I will think the E85 thing over during the winter. I can't run pure E85 because of the low availability, but I can do a mix. I'd need a flex fuel sender for sure, but also I'm not sure than my injectors or fuel pump are up to the task. Pump is a Walbro 255 and injectors are FIC 775cc. I'm worried about the rotting of the stock fuel lines with E85, but the FM big fuel kit is $1,000 and doesn't even include injectors which are another ~$500. E85 seems to be some magical juice that is worth investing into, I'm just tossing it around. My friend runs E85 in his JDM STi and a mix in his 335i and loves what it does for both cars. Basically said it dramatically increases power and dramatically decreases possibility of detonation.
What would happen if I just used 11 gallons of 93 and 1 gallon of E85 without changing my tune? Any benefits? Wouldn't it just act as a sort of octane booster?
