Вот статейка о том как вмонтировать 2 диода и куда их подключить, чтобы по ним определять начало детонации. Данный приборчик может оказаться полезным если вы часто отжигаете и хотели бы быть уверенными, что мотор к этому относится положительно.

after my last dyno visit, i decided that i wanted a way to monitor knock on my car. after some reseach i decided to install some LEDs to monitor the factory TVSV system. for those that might not know, TVSV is the factory boost controler that puts the car into "low boost mode" when it senses knock. problem is, that we disable the TVSV system when we install an after market boost controler. anything from bad spark plugs, cold/hot weather, bad gas, etc.. can cause knock at any time. by hooking up LEDs to the tvsv pin on the ecu, you get a very cheap and very realiable knock detection system.
here are the basics of setting this up:
go to radio shack and buy 2 12v led lights (one red, one green) with built in resistors. next locate the "tpc" function on the ecu. it will be on the 1st ecu plug from the left, pin6, blue and red wire. Tee another wire into that one and run it to where you want your led to go. the way this wire works, is that when u are off boost, it provides 12v, but as soon as u boost (and the ecu senses no problems) that wire changes to a ground. get your red LED and hook up its red wire (+) to the tvsv cable. hook the other end to a ground point. next take your green LED, and hook up its red wire (+) to any power source (like the cig lighter), and hook up its ground wire to the TVSV wire (same one u hooked up the red LEDs positive wire to). then install the lights wherever you want in the car.
if u did this correctly, it will work like this:
if the car is at idle, cruising or driving off boost. the RED LED will light up
once you start to boost, the GREEN LED will light up
if you are boostin, and the ecu detects knock, the RED led will stay on under boost. if u see this, let off the gas asap because your engine is knocking. youll also notice that the RED led stays on for a few min after a knock was detected. sometimes it will even stay on untill you shut the engine off and turn it back on again.
this is a great way to monitor if the boost you are running really is safe, or if the hesitation you feel is or isint knock resonse.
total cost for this mod: $4
not blowing your motor: priceless
