No one as I like knock control

 

You need to educate yourself on what AEM anti-lag does...

Please tell us what facts you know that shows that AEM + antilag" killed your motor".

 

Sean Ivey knows how to tune them without knock control. He is very familar with the Autronic ECU.

 

So do we. We make **** load of TQ and WHP with our Autronic. Been running it for years now. To compliment it we also bought a Dyno Dynamic to make tuning the Autronic much easier. Look at my signature, it pretty sum up what the autronic have done for me. lol

 

It isn't about tuning it without knock control, it's about what happens when the load changes (e.g. add 1-2 people in the car), and one has no knock control. There is no means for the ECU to adjust to a change in conditions that brings about knock. This is a distinct disadvantage, and is the only reason why I ruled out Autronic. Otherwise, it's a capable unit with nice features, but the omission of knock control seems blunderous.

Anyway, regarding the situation at hand, it is unfortunate. Nevertheless, tuning a car that has modifications always presents some form of risk. The idea of taking it to a tuner who is already experienced and skilled at doing what the owner wants, is a means of minimizing risk, but it can never be eliminated. This is the cost of engaging in this type of hobby. I might also add that tuning the car beyond a 'quickie' dyno tune takes longer than a couple of hours - much longer.

 

I read the first post. I find it odd that Brad was lazy. I do not personally know the guy but have heard good things about his tuning. It is very odd.

Also, I don't think ANY EVO needs to use anti-lag. Even our 8 second drag EVO doesn't use it.

 

Only thing I have to add to that is I've seen properly setup cars tuned very well in a short span of time. It all depends on how much experience the tuner has. As for me, I've had my own cars tuned by NUMEROUS individuals over my life time. As it stands, there is only ONE person who I would ever let tune my cars. You can find him in my sig.

 

I use knock control on every AEM car I tune, I even leave it on for race gas tunes.

I don't need it and nobody has to have it. It's like using 02 feedback, you don't have to have it but it sure is a good idea.

I don't think anyone with half a brain should tune a car so close to the edge that putting more passengers in the car would cause it to move beyond the safe limits of knock.

I tune mostly with the AEM but the reality of it is the Apexi Power FC is an excellent stand alone and about half the price. It doesn't have knock control though. With that said, I've tuned quite a few, I've never had an engine failure with one.

 

Some choose to omit knock control and I've done it myself in the past. The extra passengers analogy is to illustrate that increasing load on the engine brings the existing settings closer to the detonation threshold. But the fact remains that should something, anything change that forces the engine into a situation that brings about detonation, it quickly leads to an expensive result if there is no knock control. A MLS head gasket doesn't help matters. Let each make his own decision. I'll opt for the insurance policy of knock control.

As for anti-lag, if the AEM feature works anything like conventional anti-lag strategy, I would not recommend it for a street application.

 

yes but i had the car like 3 hrs and not even getting on the damn thing so something is wrong with the tune because i sure in the hell did not do anything to this car or else i would admit it. the car did not have anti lag on in between the shifts just for the launch to spool up the turbo.

 

sorry to hear man, hope everything works out.

 

Just to be clear here, you used the 2 step launch control once and the car blew up?

Anti Lag, or 2 step like on a stock ECU?

 

well it was a 2 step but it was more aggressive it dumped a lot of fuel and re tarted the timing so it can spool up the bigger turbos such as a 35r , 40r , 42r, 45r. helps with not bogging but now i am guessing my ignition was not strong enough what you guys think.

 

I had wondered it this is what you meant the whole time.

We're you using it and launching the car?

2step is used to built boost at launch to achieve quicker 60' and 1/4 mile times.

 

Doesnt the OP say that its wasnt turned on til requested? He might not had it on for a reason?

Ive only used anti lag on a 1g with DSMLink, I did not find it beneficalat all, except for raising EGTs. I would never use it again with any motor even a "built" with SS valves etc. My EGTs went throught the roof.

Also were the valves burnt or bent? Did you check your timing marks to make sure the belt didnt jump? Also was this a OE engine or a "built" one?
