advance ground into cam..... tuning question... 4 Attachment(s) my cam has advance ground into it (227/231 .614 .617 112+2) and was wondering if that means my timing advance will be lower? I am getting KR and my advance isn't very high at all where im getting KR?!? its only at 17-22*..... I attached my tune and a couple log files.... |
I can't read your files but what is your AFR when your getting the KR? Another common problem is headers and/or Y pipe banging resulting in KR. |
wideband is on its way.... kinda just a guessing game right now.... cant wait for the wideband... my headers and y-pipe do slap pretty good also |
You either have to get some poly/solid mounts or run a different exhaust to get rid of that. Mufflex has a bump stop deal, hit or miss on that working. |
This is just a suggestion. I see in your IAT base you have 0 across the higher temperatures all the way down to 75 kPa. You shouldn't have them zeroed at the higher tempatures. You should only half the numbers up to 131 degrees. During the higher temperatures when you start halfing them or zero-ing them out you can get detonation. My guess is your knock sensors are realizing detonation is occurring. That is why your probably seeing all that knock retard. Look at a stock tune on the IAT base table and only half the numbers between (86-131). Look for any huge cell leaps and smooth them out. |
Lean is hot and will give u detonation. Stop the banging and fix the air/fuel ratio it might work. |
thanks for the help guys ill try this if i ever have a chance soon.... been workin 15's 7 days a week for the last 2 weeks.... |
geeze i know what thats like. wake up, go to work, come home and go to bed, then do it all over again. ya feel ya live at work instead of home. |
