Tuning a GBody 6.0 swap

[lsxjunkie]

The car has a Fbody intake and rail setup. The fuel psi is 66. Which is a little high but without new rails and a regulator it is what it is.

The car has 12580426 Injectors. Does the data look correct? Overall the car runs pretty good but the trans feels like it has some age honestly. I'm going to put a line psi gauge on it to check before I start giving it all the beans at WOT. I know the timing in the higher airmass looks low, I do that on purpose while I dial in the WOT Lambda value the inch up on the timing.

Check the tune out and let me know what I can improve on and firm up the shifts some. I have the OL MAF and VE table at PT within 2%.

It looks like you know the main place to go for firm shift change is the Force Motor Current table. To truly pic apart a .HPT file it's best to have a .HPL file to go with it. As far as you mentioning keeping the timing low in the higher airmass area, without knowing the combo of parts, not having a .HPL to view, I'm guessing your not getting close to the cyl. airmass where you have drastically cut the timing.

It's a 6.0 with 228 intake duration, Circle D converter 3200. 706 heads, basic slightly higher comp 6.0. should be Mid-70-low80 air mass.

Does the injector data look correct?

I rarely change the force motor current table. I do everything with the pressure modifiers. With the force motor current table left factory there should be plenty of line pressure for firmer shifts.

This table here makes no sense. I'd put this whole table at 10 and see how it feels. If it doesn't significantly improve the 1-2 shift feel the trans is whooped.

I think the trans is cooked. Whoever installed the converter put 3 washers between the flexplate and converter faceplate. I know there can't be an 1/8 of tolerance with those in there. I usually can get my hand inbetween the pump and converter shell to somewhat feel the neck. Not with this one.

Can barely feel the 1-2, 2-3, and 3-4. Even with a 3200 stall it should be noticably firmer then what it feels.
