Hey guys I started a new thread check it out and please add to it!!!!

FWIW, those "Knock sensor filter maps 1-5" don't seem to be knock related at all. They appear to have been removed from all the evo xml files I can find, and everyone agrees they were titled wrong in the beginning. I don't think they are the solution...

 

got it...ill flash it and send you a log when i get off

 

I guess somehow i got my tune in better working order then, hmm... so the only way would be to disassemble an evo rom and look for all the knock settings in there? If there not knock maps, what are they??

 

Some people suspected that they were mivec related, some though they had something to do with other various things. I still suspect there is something that filters knock, as far as "engine noise" specific to the engine, and that will need to be moved over to the tephra. As far as knock settings though Mitsu, you're in the best position compared to everyone else, your rom is a lancer rom so the knock sensor should behave basically stock for you (I mean aside from the turbo makin all sorts of noise).

 

This is why I think the evo and lancer knock settings (all of them including ones we do not have access to yet) have to be blended. The evo sensor is calibrated for the additional turbo interference, how much that impacts the engine harmonics is unknown to me. Where as the lancer is perfectly calibrated for the n/a g94, turbo'd may very well and I suspect is a different story even using a stock rom I think we would have to find the right mixture of the two to get accurate readings.

 

As an FYI, I had virtually no knock on my base rom with the turbo, and a few degrees of timing pulled in the upper ranges. I was a bit concerned, as we are tuning until we get knock when we go for power. If even the slightest bit of knock occurs, and we don't sense it...it could be catastrophic, you know??? I'm now even more concerned, so I am going to try to test the knock sensor slowly with my current settings. I do see some 1's and 2's, so I know it's not flat out not responding...but as far as registering some actual knock...I'm gonna keep graphing hp/torq and use that as a comparison. If I see power level off, I'm not going to add more timing until I know it's teh right thing to do.

I kind of hate to ask this...but do we have any "professionally tuned" people who might say what timing they have in the WOT area? I'd like to know how far you took it, and how good it feels (hesitation, knock being registered, etc). Also, maybe we get some external knock sensors and give them a try?

+1 any input from people who are "pro" tuned about knock and what is registered. Im really curious as to what kind of knock people are seeing after a professional tune

 

Yeah, a little reading...I'm making a "det can" so I can listen to knock while driving around, hopefully that + the knock sensor + the VDR or Virtual Dyno graphs will be enough to safely tune the ol' lemon slice. I'm thinking best case would be to get the knock sensor tuned just like the lancer one, but would that be safe anyway? I think 03lances is right, in that we need to find that middle group. Perhaps the detcan is the way to find it...I dunno, I'll post my results!

 

It could have been something I did but it really seemed like I was getting more knock after turbo. At one point I went back to complete stock rom minus injector settings (still running stock maf at the time) and drove around with no boost. I assume then it should have acted just like preturbo as far as knock goes but it was definately getting more . Unless my fuel was off causing it which I will not rule out.

Also If you go to the english racing website he has a little section on how to tune. Very basic but informative. He talks about getting up to 40 counts of real knock with no audible knocking sound.

 

WHAT!! 40 counts is nuts!! i also have never heard any of my knock before

 

have you guys tried messing with "knock load"?

 

Well, me personaly no, i think hornstar ran all zero load one time if im not mistaken, but im not sure. Its hard to mess with that stuff because if it were in fact real knock and we just ignored it below "x" amount of load, it could be very damaging over time going "un-noticed" Grrr i need to make a see- through engine so i can see if knock is really happening Im a very visual learner

 

dude i have an update for you.

i flashed the tephra v7 auto rom and i did not have any problems starting the car.
in fact, it started wayyyyy sooner that stock. btw, all of the features are turned off
except for the flash cel when theres knock. imma try to do some datalogging later
this week. (ugh freakin school)

for the mean time, imma switch to my other ecu. (i have 3 to play with hehe)

EDIT: 1 fast cold startup and 3 hesitating warm startups without pressing the pedal.
