After some log I notice i have small knock when I let go the gas after
full boost, or shifting gears. It's very small, like knock ret. of 1 degrees most.
My wideband telling me rich (10.9).. so maybe less timing at ?. not sure at which load point. is not knocking at high load (~17psi). only right after (~5psi or less) .

A log would be nice. You might wanna do a search for "shift and knock" on here and/or wrxhackers.

peace

Call me as the latest software requires new knock thresholds as the old base settings are much too sensitive. I also have the latest software for your unit.

Thanks,

it's probably the utec --> ecu handoff.

Is this on a Utec or Hydra?

Factory variable valve timing working too hard? (Just a guess, don't know what car you have)

I think he has a Hydra...I'm assuming so since Phil is responding about knock thresholds and stuff.

Yeah. I got the Hydra. Talk to phil, might be the new software, so might need new adjustment to knock thres. value.
need more logs. Car run great and Strong.
I'm getting very bad gas mileage on my car. (~15mpg or less) :(
I have been putting my foot into it alot these couple of weeks. :lol:
How's everyone else's mileage rating?

Mine has gone to crap. I get around 220 miles to a tank, but its not just me its everyone around here with the state of gas and weather.
