LMM: Timing Map Feedback

[02CCSB]

I've been battling an LMM that's just doggy in the low end.

Played with the timing calculator today & came up with what you see below. It looks awfully aggressive to me in the low range. Just looking for feedback if this is normal or not on an LMM with a pretty aggressive tune.

I have this in the Med Alt A table

That timing won't hurt anything. I can't see cells below 45mm3 but I wouldn't hesitate to run that map. You can back it down if you want, it may just run a touch hotter when rolling in the throttle.

Why not use the timing calculator?

It says he was playing with the calculator?

That was with the calculator. It looked pretty aggressive to me, like 6-8 more degrees than I expected in the mid mm3 command and I don't feel like melting down a motor.

Newer mm ideas are ml ore aggressive in how the maps look.

?

I assume the "ml ore" is a typo for more? Just seems a LOT higher than I had expected...guess I will road test & see what happens!

Why do you assume its in the timing that's making the truck run like a dog down low?? So many different variables that it could be. What's your PW with that timing map? You have a drive pressure gauge in that lmm your tuning?

 

[02CCSB]

Drive pressure no, rail pressure is good.

I'm chasing the timing table because the one that is on the truck is drastically different from the one above, approx 6' on average in the low end.

The truck is just flat and gutless until about 2000RPM

whats you fuel pressure table look like?

 

[02CCSB]

Fuel pressure table is stock.

pw maxes out around 3100, comes up smooth.

My biggest concern is whether or not I will hurt a stock motor with this type of table before I start to even try to dial it in.
