![]() This is just a quick writeup of the install. So you can put the threshold at like 6 psi and everything below 6 psi it will ignore. If the engine is gonna blow, i know its not because i was detonating nonstop.Īnother feature i forgot about, is that you can have the unit only pull timing after a certain level of boost. Its also great on the car now without the built engine in. Im putting in a forged engine with tons of mods and i like to know that even if something happens i have the j and s there to save my ass. The good thing about the j and s is that it is an insurance policy. Meaning the j and s couldve probably saved alot of motors that popped due to knock and whatnot. I do believe that alot of people blow up the car due to abuse or bad tunes. ![]() ![]() These rods werent designed to take ridiculous amounts of power. you can have the SAFEST tune with every supporting mod possible, and you could still bend the rod. the max amount of power is a function of how much stress the tiny rods can handle. Well im not gonna throw a figure out for max hp on stock internals. There are a few good threads on here discussing it! but its all good, just search and you will find some info. Im at school on my laptop but my home computer has tons of j and s links bookmarked. I have timing control in my ems so i just run the knock detection where it retards timing 1 degree until the knock is gone. basically it gives you timing control based on boost if you want it to. there are also other features that you can have built in, like a o2 clamp, you can have it automatically pull a certain amount of timing in the peak torque rpm range, and you can also (which this would interest you) can have the unit retard a certain amount of timing per every pound of boost. the unit does this per cylinder (or u can have it set to all cylinders) so that you dont lose a ton of power for knock in one cylinder and not another. and after it is gone it adds the timing back in. The j and s detects knock and retards the timing in increments of 1 or 2 degrees of timing until there is no knock. that is what the knock light u posted does. "does it just say you are getting knock and better get off this s***?" plus i was planning to eventually get the j and s down the road so why waste 125 on that would it could go towards a knock sensor/timing retard on the fly unit (j and s)? i really liked the idea, but the only bad thing is all it is a warnign light (which is good and all), but i wanted something a little more preventative. my dads friend at work is big into wrx's and he suggested that. I was looking into that knock light a longgg time ago. but if this is still in your price range or even if it isnt send steve a pm and see what he says about it. maybe the mechanic ****** some wirign up, i dont know. I read about him having problems with it but he is the only person that i have ever read anything about having issues. look at yashooa, he was running the piss out of his car on stock internals and im willing to bet the j and s helped him out quite a bit. So yea they do get pricey, but i think its great insurance for your engine. I cant remember exactly but it was about 530 for the unit and about 50 for the gauge from steve.
