Default Terry or Dave help! MHD BEF E85/Race not hitting timing targets? W/logs - 12-05-2020, 12:39 AM

Just a quick question, do the ignition timing targets look normal on my logs? It seems that the E85 and Race BEF target basically the same ignition timing for me. I thought that the E85 flash would target more aggressive timing than the Race flash? The most I have seen is 9.3 degrees at full boost in higher rpms on both Race and E85 flashes. 9 degrees seems too low for the E85 flash, I thought it should be hitting around 12 degrees?

Looks pretty normal to me. You don't have any timing pulls in either log that I can see so you might be able to get away with a bit more timing. Especially if you're only running 19-21psi on TD04 turbos (at least that what it seems like based on older posts).

I personally would be happy with those logs. I'm a fan of sticking on the conservative side, which is where your setup seems to be right now. I just got some RB Twos installed the other week, and the MHD Hybrid Race map is a little too aggressive on timing IMO.

Mine seems to be targeting about 12-13 degrees on the top end. A bit too much timing on E30 fueling for my taste. I'm also only on about 15-16psi so I suspect the tune would pull a little more timing out if I were at ~20psi.

Thanks for reply. Something has to be wrong though, there is no timing difference from the Race or E85 flash on my car. Even in map 1 E85 flash it's only targeting 9.3 degrees max. Any reason why my car might be limiting timing?

Help Terry or Dave! thanks
