Modified VE tables. Is this OK?

Post by rtc1757 »

Hi,
I have an MS-2 V3 running a port injected BB.
I just added twin turbos and I raised the top Map bins to 140kpa.

It runs and I am starting to tune, but this is new to me.
I have a copy of my current tune if anyone has suggestions.

Also it has a hesitation I am working on when opening up the throttle.
pretty severe and I havent quite got that figured out either.

Thanks,

Rick

It's hard to judge a tune in a vacuum unless something is blatantly wrong; it's better to have a data log. But I can see you forgot to modify the spark table. I'm not sure what sort of engine this is, but I doubt it wants 36 degrees of timing at full boost.

Thanks Matt,
I should have given you the whole setup.As far as spark I am just controlling fuel currently.
It is a 500ci BB mopar,Running E85 and 60lb/hr injectors,

I have only run it on a stand so far, but do have a cooling system.
I have an LM-1 wide band I have been using to try to dial in the fuel.
I have not been using the ego feedback yet, just the LM-1.

I have a nice idle but quite a flat spot when I open the throttle.
I will post my last datalog later. If you have any ideas on the acceleration, let me know.

Rick
