I have this posted in the U.S. Lancer forum, but you guys would benefit from it greatly also, so that you guys see it here is a link to that thread!!

do you mind not spamming the forums? Thanks.

 

I'm not spamming the forums... so lighten up. I'm a contributing member and only post stuff that I actually think is worthwhile. Talk to HobieKopek as he knows me a bit on here and knows that I try very hard to post good stuff and not be confrontational. So discuss it with him if you have issues with me. I posted this in two places because I know that a lot of Evo guys don't read through the US Lancer stuff and it is something that everyone can benefit from. I know of a few turboed people using this and a brother of mine is looking at purchasing this as well because of the benefits it can bring and safely allow you to adjust aspects of your engine and setup to get greater performance safely. It is very interesting and different engine technology from what we usually look at and think about and is a good topic for discussion on these forums.

So lighten up and actually read what I posted.

Steve.

 

In case you don't realize the value of a technology like this it essentially protects you from detonating your cylinders. Makes it possible to safely run more boost and different things essentially allowing you to safely adjust timings and boost and the like and be worry free from killing your pistons from detonation.

So more horespower safely is a VERY good thing.

 

The car autmoatically yanks timing based on detonation., so now there is a product that will pull engne timing without knock? Basically limit HP? AS you pull timing, you pull back HP, you want to run as much as possible.

 

Factory units can only adjust timing by up to 5 degrees. From my understandint of this thing it can adjust timing by as much as 20 degrees with some of the units. It also determines which cylinder has the issue and ONLY adjusts that one back to prevent the detonation/knock. Then it readvances timing as it can without getting another incident. It can also adjust timing for midband torque and a few other things. Keep in mind this is a SAFETY device not a performance enhancement device. It essentially will allow you to avoid detonation regardless of humidity and so forth and a ton of other stuff WAY over my head currently... I'm still learning...

 

I had one of these units on my FD RX7 for years, it is a very cool system and never gave me a problem. It has a display so you can actually see when your engine is knocking and you can set the knock sensitivity with it. I don't know about every one else but half the time I cannot hear when an engine is knocking.
The rotary is probably not the best example for this devices track record, those engines are just way way to sensitive to detonation. Unlike piston engines, one good detonation and it's all over for the apex seals, so I still popped motors with it, maybe just not as often? .
I noticed that the newer RX7 J&S systems can also drop the boost when they sense knock, I wish mine had that feature. On a piston engine that can handle small amounts of detonation, this thing could really be a Kevlar vest. With this system in there I would seriously consider just removing/isolating the stock knock sensor.
This device will enable you to run more aggressive timing, giving you more power with a greater safety margin. When it does sense knock it is able to perform more precise corrections and only to the cylinders that need it, there by maintaining the highest power output at all times. If you see the system retarding the timing all the time then you know that you got some bad gas or you need to adjust your fuel/ignition curves. Either way I wouldn't keep pushing it in that situation, it's a very cool safety feature, I plan on getting one. Also they claim it increases ignition energy, that's also a good thing, especially if your upping the boost.

And no I am not a salesman for this product, but I really do believe it has merit, especially for those people running 91 oct. I know many people besides myself who use it, never heard a single negative. Testimonials from well known people in the racing industry don't hurt either.


Just my 2 cents,


Eric

 

I'm tired so I'll keep it short... search the web for all the Pro import drag racers that not only use this little jewel to safegaurd the engine, but also use it to tune to the ragged edge of detontion... many "famous" engine tuners already have these little dandies hard wired into their engine dyno harnesses to tune everything out of their shop.

 

I read it. It sounds like an ad. I can understand excitement. The amount of excitement involved here sounded a whole hell of a lot like an ad what with the crossposting.

Sorry.

 

Understandable then... it's all good. It'd been a long day and I was probably a tad overexcited because it'd been a crappy day and finally found something kinda cool in the day!

Also if you don't recognize my name on the forum and I come and cross post and quote a manufacturer website and the like... then it'd be easy to make your assumption.

I'm glad to see that some people on here have used it before as that was largely what I was curious about as well as trying to expose people who could benefit from it to the idea of it. Especially useful for US Lancer people who are tuning their engines pretty far up without forged internals. I've already seen a few pics of cracked landings and destroyed pistons.

 

Yup I lost two motors in my FD due to detonation. Sucks cause I loved that car but couldn't afford to keep putting motors in it.
