People will say not to use a phone app to monitor KR, other say the bandwith isnt an issue because the pcm is over 10 years old and a smartphone has more processing power.. However phones and apps arent perfect. To my knowledge nobody has compared the results yet.

I do however have torque pro and the bluetooth adaptor. It seems to update the readings about twice per second. It took me a few minutes and a couple google searches to get KR to have a screen for it, but there is a function to monitor KR and also the number of knocks it's recorded that session. It has a boost/vacuum guage as well, and can scan and clear codes from the check engine light, although it is a little slow doing so. About 30 seconds to read codes, another 30 to clear them.

Overall, great app! But I would trust an aeroforce guage over a phone app. I'll be checking how accurately it tracks Kr over the summertime though compared to aeroforce.
