im usin .018 never had a problem

 

with an HKS dli2 you guys could run a .028 gap without blowing it out. I was running 31 psi on my 05 evo with the dli and ralli art wires and the car ran awesome.

 

hitting a wall and a misfire would feel completely different from each other. Am I missing something here.

 

interesting... did your symptoms manifest at a higher RPM or lower like mine?

 

i didnt feel a problem until i hit around 2500-3000 rpm at WOT and started getting into boost, then the car fell on its face

idle was fine, low rpm WOT was fine, cruising was fine, high rpm cruising was fine...it took me forever to figure out the problem...but that is what it was...unfortunately, this was when I had first started modding, so I didnt have data logging or AFR numbers...so I cant help you there

 

Do you have your stock air box/snorkel? If so, make sure that your snorkel has both of the plastic rivets in it as this has caused engines to have the air supply choked, resulting in a symptom that you describe..It's worth checking into...

 

yes still on the stock airbox and the snorkle is attached.

Again this problem is happening @ 2.4k RPM not lower and not higher. If I lift halfway off the throttle right as its happening the car will pull through it. Anytime I go WOT above 2500 RPM there is NO problems, its only when I nail the throttle @ 2k and boost starts to build that the problem presents it self.

 

Have you tried bumping up the boost cut delay timer? And the boost limit?

That is about the point that I jump from 140 load to 280 or 290. When you get in it low in the rpm band you make a serious jump in load in the space of about 500 rpm. At 2500 im at right around 140 load, at 3000 i'm at 280/290.

 

boost cut delay timer is at 1000 and boost limit is maxed out at 319

I'm curious how do you know which load cells your in?

 

From looking at the timing values, that is why I drop timing down as I move to higher load cells, at least for testing so I could figure out what load cells i was hitting.

I think the boost cut delay timer is in milliseconds, so crank it way up, mine is at 1631950, way excessive, but then again so is 319 for the boost limit. at 1000 it is probably 1 second.

It certainly seems the issue is related to the rapid change in load cells that occurs at the point during spool. I would try and raise the boost cut timer to 10,000 and give it a run.

 

This is the question we need to know. People are working on it. If we can know the algorithm used to calculate load it will make this process much easier.

Here is a thread that covers this:

Agree,

In the mean time you can scale your timing values so that you can at least aproximate the path through the cells, but then again, this requires loging the timing and rpm at a minimum, this what I'm using my utec for at this point.

If you look here:

at post #5 you can see the logs and the aproximation of the path that i based on the timing logs.

 

Interesting. Thanks.

 

DING DING, gold star for mad_VIII. Ramped the value up from 1000 to 10,000 and that did the trick!

Thanks for all that helped, mad_VIII next time your in philly I owe you a round of

 

Wow,

My advice was actually usefull haa haaa.

Glad to hear it man. Now if i can get some good log data tis weekend I will post up an desktop dyno spreadsheet we can use to track changes, got all the equations just need some good time sampled data, utec sample rate is not real good for this type thing.
