    Hello guys, are you use start of injection table to increase injection time? You would raise these numbers?

    Hey all, I also have an LNF zfr6758/opels/ttr intake/aggressive boost ramp/26psi and I'm getting what appears to be spark blowout as well.

    I pulled the spreadsheet from this thread and I'm trying to follow what actually needs to be changed to what.

    My fuel pressure doesn't drop but my timing goes negative and I get what feels like a misfire - this leads me to believe the fix is in the injection window as described by the fixes in this thread.

    Here is what my Injection Angle Horn Single Low looks like after I bumped it from 3-7Krpm and >150 load to hit the max 431* in the upper cell and then smoothed it. I assume if I still get it I'll need to up this value in the RPM I'm seeing it? I still don't understand how I'd use the spreadsheet or optimize if that's the case.
