Thanks guys I was overthinking it. Got the local one at az.The new spring is much stronger the the 30+ year old one. It has a plastic pulley but I can replaceit at some point.

I find it easier to dial in the ve table in hex view.(Right click on the table and click show raw values) You can also set a cell to ff and then switch back to calculated view to find the maximum value in decimal.

Fixed hard shifting into third with fn3ulk, I zeroed the 2nd column to force unlock on all 3rd gear upshifts.
I didn't figure out the conversions so any help with that would be awesome.

Func_b73a - FN2LK = Speed ratio delta to relock on upshift to 2nd gear.
Func_b75e - FN2ULK = Speed ratio delta to unlock on usphift to 2nd gear.
Func_b792 - FN3LK = Speed ratio delta to relock on upshift to 3rd gear.
Func_b776 - FN3ULK = Speed ratio delta to unlock on usphift to 3rd gear.
Func_b7ca - FN4LK = Speed ratio delta to relock on upshift to 4th gear.
Func_b7ae - FN4ULK = Speed ratio delta to unlock on usphift to 4th gear.

Getting ready to move to my f3v2 chip to free up the QH. One last issue is the trans slams when doing manual 1st to manual 2nd shift but only when throttle is closed. Can that be fixed in software?

I need a new one. Any recommendations on brands or enclosed/visible spring?

gracias

Looks like FN1129 is causing it. Should I just zero it out or is there a good way to figure out how much timing is necessary?

Assuming you don't care about a touchscreen or 2in1 convertable.

If you can spring an extra 100 bucks:

I still think doing a UV erase / in place reprogram of the factory eprom would be the most useful development. I love the quarterhorse but being able to reprogram the box when done tuning would be amazing. Any hope of using something like this to reprogram it? I have a ECU with a bad injector driver I'd be willing to donate for testing purposes.

Is it better to pull timing or add fuel when towing? I I'm thinking towing in first gear is going to be pretty light throttle once up to speed so it'll be running stoich. Should I just add some digits to the bdl table?
