I was wondering if anyone with the Intense kit is seeing any Knock Retard on the OBD II scanner. If so what throttle and rpm does it seem to happen? Uphill, coasting ect...

 

you should only see knock when you first nail it and then it goes away.

 

Was just wondering how high the numbers are when you first hit it?

 

No more than 3-4 counts. It's fine man. Put the kit on your car. But first.....get a clutch from them too. Trust me.

 

I got the kit on now. Thats why I ask. When I cruise it get KR uphills in 4th at 2100-2300rpm. I'm still playing with the settings. Just looking for some advice. Haven't had much time to do it yet. My clutch doesn't slip yet but I plan on getting one soon.

 

If you were smart...you'd do it sooner than later. Meaning...call Monday and order that thing. Lol. Trust me, you don't want to be 230 miles from home and have your clutch explode leaving you without a car and missing it very much for 2 weeks.

I get some knock uphills in higher gears at low RPM too. Less than 4 degrees for less than 4 seconds isn't going to hurt anything.

 

Spark Knock. You might need better Plugs.

 

Excuse me but WTF is spark knock?

 

When your car knocks, it is like a pause when your going thru your RPMs. Usually happens around 4k to 5k rpm. Your code will read a cylinder misfire.

 

I'm getting like hesitation it feels like under part/mid throttle positions...also I moved to D2 setting and it seemed to run better. I just checked my log that i had and it looked like im getting no KR really anywhere. I need to get an interceptor...im tired of having to wait to get home to go over stuff lol.

No no no. First there is no such thing as spark knock. The only knock you recieve from an engine is knocking from pre-ignition of a cylinder. Meaning something within the cylinder (Spark plug, piston, cylinder wall) is so hot that the gasoline ignites before the spark plug does its job. This is bad. This is picked up as an explosion and harsh vibration rather than a burn by a sensor in the engine that picks up vibrations with precise algorithmic programming so bumps in the road and stuff don't set it off. This sensor tells the PCM there is pre-ignition and the PCM in turn retards timing to help cool the engine and allow more fuel in to keep the mixture from exploding in such a lean condition. You will feel no sudden jolting pauses, just a slight loss in power momentarily until the PCM has a chance to cool the engine enough which usually happens in a few seconds.

I also am running at D2 rather than C1. Do you have any intake/exhaust mods?

 

I have an intake...but even at d2 I still have surging. Also my long trim fuel tables are -17%...and it looks like im going tru gas a lot quicker lol...probably all the full throttle runs

 

Set your base back to C.

 

why out of curosity?

 

Since when did any amount of Knock become "Fine".

Knock is to be avoided at all cost.

Hesitation is another issue all together.

Knock is the Precursor to Detonation.

 

Thats what I thought too. A lot of people on here have told me that a little bit is fine, just as long as it's 4 or less only for a second. I don't really trust seeing any knock. I wanna get rid of all of mine but don't know how yet.

 

Since 1997 in the grand prix GTP. They come with KR from the factory. As they do mods the KR reduces.

 

So a Band Aid is the Solution to an severed Head?

Detonation should never be brushed off as OK..

Allow a knock sensor to be the solution to knock?

Why not look deeper than that, that's like fixing a leaky oil pan by putting silicon on the outside of it.

Fixing the problem with proper tuning is the solution, not some cheezy device that will one day malfunction and cause a total nightmare.

 

Do you run 91 octane gas ?

 

Ya I run 91 or 92 octane gas. Which ever is abalible at the time. Does the 2.0 have KR from the factory? Has anyone checked to see?

 

You need to run 93 minimally. READ YOUR OWNER's MANUAL.

 

If its sooo detremental (which it is on cars that cant control it) why is it on cars that leave the factory and why do these cars go hundreds of thousands of miles and why did they receive top 10 engine design awards for years?

 

Owners manual saids that you can use lower grades of gas.

Anyway, 93 isnt sold in every state.

 

YES AND YES!!!

REALITY check! Yes KR is bad but ALL engines get it to some extent. You want to minimize it to 0 to get max performance thru increased timing. Thats why we have knock sensors and knock retard! The computer protects the engine by retarding timing. You do loose performance but not your engine.
