Yeah, I've decided that closed loop is the way to go after driving all the way up there and having the tune lean out significantly. You gonna stick it in OL or CL?

finally i found it again. ive been tring to find this thread with no luck for months.

awsome build up. im looking forward to the finished product.

It will have a fairly conservative closed loop enabled tune with COS3 when I get all done with it.

Just curious, where do you have your throttle position set for enabling PE mode? I put mine at 28% all the way down the entire table, which is right about where I start to cross into boost at lower RPM. Higher RPM requires more throttle, but I rarely run in vacuum at high RPM so I didn't think it was a big deal.

In the COS tunes, I don't use PE (it's set at 14.68 all the way down), I just use B3647 so any time it goes into boost, it richens up.

How did you get it to work? I'm using COS3 and whenever I go into CL it disables that table for me. I had to use the PE table to do my OL fueling.

You actually only use a semi closed loop. You don't re-enable closed loop in the tune, you just put 14.68 in most of the B3647 table and it will use short term fuel trims to keep it at 14.68, then any time you get into a cell not commanding 14.68, like in the 80-100 kPa column, it goes into full open loop and fuels to what ever that cell is commanding.

Oh yeah, that's right. I actually put mine back into full closed loop. That's why I lost the commanded AFR table. Makes sense.

Up DATE TIME!!!

Ok guys, FINALLY got to drive the beast . and man she runs GOOD! Only running 5psi right now, and a VERY conservative tune till I have time to dial it in. I need to do some more work on the front steering though, has some really bad bump steer, so I think I'm gona have to put cross over steering on it. It's riding pretty rough too, but I think the box will help that, if not, I'm gona put some 1500# sleeve type bags in the back, and they should ride better. I got my seats put in too.

Oh, and their's a video in here for all you video freaks too,
