I am getting the Yank TT3200 converter and doug thorley headers with no cats put on this week.I need to know what to change in my tune for the converter and headers.Our local 1/4 mile is opening within the next few weeks,I want to be ready.

 

tune trims and might want to increase tcc lockup pressure, if your removing the cats delete all SE codes for the rear 02's, no need to mess with sims then

 

In what chart on HP Tuners can I increase TCC lockup pressure? Also should I tune what mph it locks up at?

Thanks for the help.

 

Its under the tcc tab in the tranny window, I forget the exact name.

As far as what mph to lock the converter up at that is up to you and whatever cam youve got, my table is mostly stock except for bumping the speed up at low tps to avoid tcc lockup under 1100 rpm it puts alot of load on the engine with a bigger cam causing kr.

One thing you definately want to do though is to set the 100% tps column in the tcc lockup table to 256 as the stock table will lock the tc at 80 mph regardless.

 

with my shift kit and tc install i didn't have to change i put everything thing stock. but if you don't have a big cam i would lower your lock up speeds just a little for around town driving. mine locks up about 35 mph with light throttle but if i have to push it down very far it will unlock for higher loads. but with ut a shift kit yeah you may need to raise the lock up pressure table.

so 02sierraz71_5.3 you say it will lock up anyway at 80 even if the tps is at 100%. i may have to look at that then what is the name of the table can you look? i would but i'm at work.
