Chasing Knock Retard issue

Hi all, I'm currently chasing a knock retard issue. I'm getting KR between 4500-7000rpm, kr is going up 'n down between 1.0 and 3+/-. I'm in the tuning process of this car and I'm trying to find out what this issue is. My setup is as follows: CST4, Catless Downpipe, 3,5 downpipe, 3 port ebcs, vtcs d...

Re: Pops and Crackles Disappeared

After logging, noticed that I wasn't dropping below the default 0.1875 load value to trigger the retarded ignition timing on decel. I related this to having raised the IDLE RPM - In Gear to 700 and IDLE RPM - AC ON - In Gear to 800 . But could be other reasons. Also switched the BOV to 50-50 becaus...

Re: My car won't pop, burble or crackle

I've read all your posts but it's still unclear to me: - what you want to achieve (expected result); - what you actually get (the actual result); Posting your tune (+engine mods list) along with mentioning clearly the things above may help. Hi Mituc, So what I want is: Lift burble, each time I step...

Re: My car won't pop, burble or crackle

You've set it to -20 BUT the timing you are getting is like 5 and the load does not go below 0.22 under decel (or if it does it comes back up quickly). Also in your log you have some useless parameters such as fuel injection amount and catalyst temperature (on a catless car!!) but no AFR/Lambda, de...

Re: My car won't pop, burble or crackle

Looking at your logs it seems you're getting about 5 degrees, if that, of ignition timing on deceleration. Generally speaking, I'm pretty sure you have to be targeting around -10 or -20 or so to get some decent pops out. What have you set the max ignition too, and are you still running stock cats? ...

My car won't pop, burble or crackle

Hi all! I have a 2006 Mazda 6 MPS with a custom tune, CST4, fmic, catless downpipe, and all the other supporting mods. I ran the car with my custom tune for a year, and my car only pops sometimes when letting off throttle because I have a vta bov. Now I have been trying to customize my tune to add s...
