Help me to understand M60B40 W.A.R load(ms) tables

[Mykk540i/6]

Hey guys,

Just installed my W.A.R Chip and running a slightly modded Miller 92oct for my 404 DME 540i.

I will be installing a wideband in a week or so in order to dial in fueling. My question is;How do I decipher the different load boundaries. Under what driving conditions are what load cells are being used? Does coolant and air temps shift over the loads? Hotter temps = more load, cooler = less?

What max ignition timing is considered optimum for the M60 combustion chamber design (on 91 pump)? I see miller runs up to 29 degrees in the high rev with a few cells hitting 32 degrees in the mid-rpm range.

Would any of you mind sharing your M60 404DME street tunes to help a newb absorb more info about these systems?

Can I switch tunes via the four way selector switch while driving?

Thank you -Mykk

Here's a thread I started about the war chip load axis.

Yes you can change tunes while driving.

Thank you, good read.

Does anyone know how to tune out the engine overrun exhaust backfiring during closed throttle deceleration? I've played with the idle and p/t ignition timings to no avail. Thank you -Mykk

I'm running a custom 4" system on my M60B30 and now M60B40

There was a HUGE backfire around 1,900 rpm when backing off from high rpm and coasting in gear (fuel flow off) and the fuel coming back online, it was LOUD , like a shotgun going off.

I came up with a non software solution.

I gave the TB a minuscule air leak with the throttle closed, about a hair width. The TPS still thinks the throttle is fully closed.

Fuel cut off on coast is now coming back on at 1,100 rpm.

Don't ask me why it worked but it cured the backfire.

I'm guessing you're running a non stock free flow exhaust ?

Yes, that's correct.
