1.6 lt, td04 at 13psi, ic, 320cc inj, what do you think?

18psi 06-03-2014 12:28 PM

Its relatively aggressive. Though Joe Perez and a couple other people have run something similar to this (though only up to 100kpa) without breaking anything.

What fuel are you on?

....And why the heck are you running 30* at idle?

95 ron

yep, managed it to stay around 20 on idle...

20 degrees on idle? why?
is your engine timing way off from what the megasquirt thinks it is?

last release, a friend of mine told me to set timing at the lower mkp value at idle, it was around 18°

you're just wasting fuel and potentially making it idle high

only time I'd run that much is if the car absolutely refused to be smooth with any lower values.

just an observation

that's better. is it stable and smooth?

Pepino 06-04-2014 01:55 PM

seems to be, just falls a bit low when stopping...

Personally, I'd stick to DIY's base map until I visit the dyno. Obviously check and recheck base timing, find out what your engine likes for idle timing, autotune fuel, then visit the dyno to make power with timing.

I usually bump up the cells under the idle kpa and rpm lower than idle rpm slightly. so if you idle at 1k 35kpa I'd have cells at 20kpa about 2-3* higher and cells at like 500-700rpm 2-3* higher

so when it droops, it falls into those cells, and they "bump" it back up.

tuning closed loop idle valve is also important for this
