Last week in Revy I was riding my proclimb 800 turbo, and I was having detonation issues. I was running 50/50 112 rg/pump gas at 10psi. So the next day I ran straight 112 rg and still had a couple det codes (ecu21) on the display. My plugs looked fine, my afr was normal, the sled didn't bog out or fall on it's face, my knock sensor is tight in the head, I don't understand... Should I be worried about this? I'm running a stage 2 ovs hot side, boondocker intercooled cold side, rktek turbo head and a boost it box. I'm gonna change my plugs and maybe take my knock sensor out and reseat it in the head, and run straight 112 again. See if that does anything. Is there any other little things I should check for that could cause detonation codes??

check for ANYTHING that might be hitting something when the motor is running, and check torque on the sensor itself. This happens from time to time... COULD be a bad sensor, but I'd put a shiny quarter on it being something hitting fooling the sensor.

Do you know what the exact Torque spec is on the sensor?

I have strange det codes from time to time as well. I wonder if it isnt a rev limiter thing similar to the poos.. . just something to thing about.

Do you have the stinger in the pipe cut? That has caused lots of det codes for us in the past

Mine did that too me last year in Revy running 10 on straight AV all day. Did it even at 8. Next day reeds exploded so they were chipped. I'd check your reeds! Put turbo ones in an haven't had a problem yet.

Yup major pain. Running boysen turbo specific. Been great. Lasted all last season and checked em pre season an still mint. Probly 1000 miles on them. Go on eBay an buy a 25 dollar lil bore scope cam you plug into computer. Take charge pipe off shove in charge box. Works perfect for quick checks!

That's a pretty good idea! Thanks snopro! I'll check those god awful reeds on days off and see what I find. I have a set of boyeseen turbo reeds in the shop I pulled from a buddies sled still brand new, the guy tuning his sled refused to tune it with those reeds, said they were prone to cracking up.
