This is how my Mercedes Benz W124 from 1987 with the M103 3.0 engine accelerates from 0 to 100km/h. It's running on a Megasquirt ECU. I am not satisfied yet, this is a rough 10 seconds, the 300e with automatic transmission should do 7.8 seconds to 100km/h.
But, according to specs and tests, it already takes 9,6 seconds to 110km/h. And this is for the 188hp non-cat version, I do have the 178hp version with catalytic converters.
With my EFI setup, further absolutely bone stock, even down to tire sizes, I should be able to at least match or exceed those times? Megasquirt MS3 1.5.2 with EV14ST injectors, VAG wasted spark coilpack etc, semi sequential injection.
AFR @ full throttle is 12,5 (14,7 = lambda on 98 octane shell v-power)
And my ignition angle is 31 degrees BTDC from 2500 rpm, which drops down to 29,5 from 5500 rpm to 6500rpm. 6200rpm redline.
Any thoughts about this?
