i always heard you want to lower timing to increase the loop. if thats what your trying to do and your at 8* try going to 6*

my friend's evo 8 is at 5* and its lopey!

 

You meant to lower ignition timing for more lope. 5* should give you lope alright.

Whoops, yes I did, thanks for pointing that out. Edited my post.

 

they are degreed and tuned in... making 320kw @ 28psi @ 3700rpm...... on e85

 

I think you mean duration. Lift is how far the valve opens. Duration is how long it opens for.

 

Bumping an old thread but I have HKS 272s in my car and the idle sounds so nonchalant, I don't really know anything about changing timing of my idle to get a little loopyness, can someone help me out and offer some guidance?

 

check your PM

 

Interesting thread I didn't come across initially. I am getting set to tune for my Kelford 272s on a 9, and the lopeyness was something I thought about, but the other direction. I actually wanted to see if I could tune to pass smog, and particularly at idle the overlap would cause worse or higher readings from a sniffer. At least that is what I have understood from the reading so far.

Can anyone comment on the notion that adding timing in the idle cells at 1000 rpm and below would actually improve the sniffer. Or said another way is the lopey idle and smog sniffer inversely related?

 

as stated the lope is all in the timing, fuel, and cam gear settings along with base idle. i have mine set at around 750-800rpm. here is my 8 with hks 272's. to me they hit a nice lick and often rock the car back and forth at idle. actually had quite a few compliments and a built subie back down and the owner tell me "b***h sounds nasty".

Dang, That sounds great. I have these same cams and my car was tuned and it lopes sometimes but loads up on fuel and dies sometimes. I am trying to fix the tune but I am new at this.
OK tune guru's, if I only change mt timing at idle to basically from 0-1000 first and second load table to 6* and the next table to 7* and the next table to 9* will this work to hear the cams? I am new and trying to see if I did it right. Thanks
0 load 10 20 30 40
6 6 7 9 10
6 6 7 9 10
6 6 7 9 10
6 6 7 9 10

 

You're generally between 30-40 load at idle. So you'd want timing in that area to be lower if you want it to lope. You could actually inverse that timing curve to have it like this instead:

10 9 7 6 6

 

Ok Thanks I will have to try this. I sent my ROM to Appauld and he said it is a very old rom, it is one of the first ROMs used. My ROM # is 94170008. My tune to me looks very crappy, in the middle under boost it has one block that was like 18.3 if I remember correctly. Learning all this info is like information overload to me. I am trying and by the end you guys will probably be ready to kill me. Thanks for the help.
** Well I just went back out to get my Immobilizer code and write it down and I couldn't read the Rom. I tried to do the sicky stuff at the beginning of this section and nothing worked. I cannot even choose what model car I have. I am not computer smart so now this is getting really hard for me.**

 

Ok, got my ecuflash fixed and installed notepad++ and got it working but I cannot understand what it says or how to convert it to look like everyone elses. Sorry guys I am a NEWB and am lost.
This is what mine looks like in Notepad, if I can get it to show up here, well I tried and it won't copy and paste here for some reason.. Anyways it just looks like a bunch of letters and not the <Blah> <Blah> like everyone else has. Anyone help me??? I am wanting to do the egr delete to see if it helps fix my idle issue. My car if you rev it and let it fall back down to an idle it will load up and smoke black or sometimes fumble and die. I would also like to put the code in to fix the misfire in the 03 8's. Thanks and sorry I am so dumb at this guys..

 

Make sure you are actually opening the xml files from the rommetadata folder, and not your ECU ROM file. Without seeing anything its tough to troubleshoot. Start a thread in the ecuflash forum, but provide a screen shot or the exact steps you are taking. There are so many skilled and experienced guys there all the time, you will get tips into the direction of a solution or the solution real quick. You might get more lookers there too, compared to here since this is deep into the loopy idle thread. {thumb up}

The key I have found is to search for exactly what you are experiencing. Someone else or several have already had that issue. That way too, you don't have to wait for responses.

 

You nailed it. That is what I am doing, I don't know how to open the metadata in Notepad. Last time I tried I lost everything and couldn't open nothing, I couldn't even get the Ecuflash to work at all.
