Improved 4R70W Tune

[Stanger007]

I've been working with my 4R70W tune taking inputs from several sources, most notably Mike Glover's latest PDF.

I wanted to post it up as well as post up the changes from the stock tune for anyone with the same tranny.

I've still got a few things left to try on my "to implement" list. Any suggestions are welcome - it's tough to find a lot of in-depth information on the automagics.

I've also looked at a couple other tunes, one from Jerry W and another "Level 10 4R70W" tune and saw that they changed the delta_ratio_for_* scalars, I haven't found out what role these play yet - anyone know?

I will have to look at this

are your 1st and 4th gear ratio different?

The ratios are set to 2.84 (1st) and 0.70 (4th).

Also, for those with 4.10s, I'll be posting up an updated tune with the N/V settings changed to the SCT recommendations for 4.10s later on once I try it out.

Made some minor updates updates. "torque_convertor_lockup_rate_after_tip_in" is the only tranny-specific one applicable to everyone. The others were new values for my 4.10s (which affects the tranny) based off of SCT's values, exhaust pulse delay settings based off of SCT and finally a further tweak to make sure the 3-4 shift doesn't happen at WOT.

good stuff. thanks again

where is that setting (torque_convertor_lockup_rate_after_tip_in)? i don't remember seeing it anywhere. i'm probably just blind

btw, i updated the tranny page that talks about speedo gear selection.

that wiki site is already great, and will only get better as more people contribute.

Thanks for updating it - I'm finding it useful for myself as well!

I'm using CalEdit v1.30B3 - it's on the last page of scalars.
