I have the same issue. This is my 5th tuned mazdaspeed and first mazdaspeed where i see tons of knock at cruising conditions. 2200-2700rpm. Of course, this is my first built engine, balance shaft delete, twin disc clutch, ported head mazda though. If any of my other mazdas knocked it was logged once...

Last night i changed my open loop AFR target to .8 or 11.68. Updated the timing limit for the load values i am seeing with the bigger turbo and downpipe. Then went to my favorite back road to log a 3rd gear run. Virtual dyno has me at 359hp, 100% IDC still. Was grinning like an idiot for the first t...

After more research, went out and logged Injector duty cycle. Much to my surprise i am hitting 95% at 5500rpm at only 20 psi. I suspect that is the last thing holding me back. I certainly dont feel comfortable increasing that value. I am going to dial in my maf calibration and maybe pick a slightly ...

I think I found my problem. I didnt update the absolute limit tables for overboost protection fuel / throttle cut. Now i am hitting 22psi at 4k and it tapers down to 19psi at redline. My goal is to hold 21-22 from 4000 to 6500. I am still targeting 2.1 Load but only getting 1.9. Normally we increase...

I have the BNR S4 installed with a 3" downpipe now and 3" JBR intake. I scaled the maf values up 20% then a crude maf calibration (not perfect yet) I am still dealing with the same problem I had with the K04. I cant hit load targets. I thought the stock exhaust was holding me up, but it mu...

Now that ive had more time to work on my map, i do have a question. I enabled megaspool yesterday and tested it (not actually launching) It was slow to build RPM, once it hit 4100rpm it was showing 6 degrees of knock. If knock normal during megaspool??

Hello, A few weeks ago i bought a mazdaspeed 6, then another two weeks later just for parts. One needs pistons, the other is currently my daily driver (stage 1) Versatune pro OBDlink SX Cobb intake / SRI Muffler delete Billet wheel K04 (i suspect its a cheap china turbo) ----- Parts not yet installe...
