I don’t ever really have to insult anyone to share information or ideas about cars. But thanks for filling up my thread with information about SUV’s.
Saying APR didn’t blow this motor is like denying climate change. You can make the argument but why would you?
^^ Shut the fuck up, dude. Seriously. Your time on AR is quickly coming to a close.

great first post
And once again West can’t resist being a troll and gets suspended as a result.

and it was not knock because the logs showed nothing knock wise or timing pull wise.
it was cylinder 5 that imploded on those cars where the motor blew. Mostly the race file. Happened to one guy on the forum, then jspazz, then friedgreentomatoes.
how long ago were those cat engine failures?
Wasn’t there a signal like “misfire totalizer” that went from 0 to 300 during a single pull? I thought this combined with zero timing pull from knock mic’s and engine going boom was the evidence needed to draw the conclusion.
cat engine?
not sure, but the poster said ‘weren’t logs showing significant cylinder 6 knock’.
sorry - I’m an insurance guy, cat=catastrophic.
ah ok. These were 2011-2013. I believe they changed the parameters quite a bit.
in other news, this thread is nice and quiet today. A lot less stupid.
Yeah my mistake, it was cylinder 5.
I believe Arin posted some logs a while back that showed Revo’s modified knock sensor map. Looks like their new tunes are much safer.
Thanks- exactly why I was asking.
If you want some good discussion about revo’s most recent tune revision (stg 1+), I’d check out some of skywagons threads with the revo software (minus all the bickering lol). He took logs and we discussed them in those threads.
The tune was shown to pull timing due to knock detection. A revo engineer on AZ did claim that they modified the ‘timing pull due to knock’ sensitivity of the factory calibration. His claim was that this was an ideal way to tune the Simos 8.x, specifically, the calibration strategy that allowed for the most aggressive/safe/smooth timing curve.
In practice, we saw in skywagon’s logs that his bypass valve was opening a lot, usually close to redline. He went back to revo for a custom day on the dyno, I don’t really remember if we looked at his logs after that.
Yes, I did, in fact, put out some logs.
Thanks! I did see his posts on AZ - one of the few useful things I found on there actually ;). I had my tune done after Sky’s @ Revo HQ in WV so I’m not sure if they incorporated anything learned from his vehicle in to later tunes like mine or not. I’ve been trying to plan a trip to Mason Dixon Dragway for a few passes to see how the tune performs but mother nature has not cooperated. I’ve scheduled to go with a friend who has a '15 w/ a Revo Stg 1 tuned S3 on April 11th so here’s hoping the weather is good.
Skywagon has been very open about his tune and results. I think primetime looked at his data. Skywagon still seemed to have a reduced mph but his car seemed safe in the tune. The revo guys might need to thank Skywagon for putting his car up for revo to fix there issues.
If anyone wants the logs I can e-mail them to you. I’ve done a lot of thinking about my top end speeds. Not sure about anything but my car has about every option one can put on it and I’d wager with me in it it’s total weight may be pushing 4300-4400 lbs? That could be part of my slow trap speeds? Regardless, how much REVO’s “custom” tune helped my car can be seen in one time slip. 11.98, 113.5. From an overweight luxury sedan I’d write that’s not bad? I’m sure REVO learned a lot from my car. They said they would send me logs but never did. Suspect they may be protecting trade secrets?
