I will make one calibration change for an additional $100 per change. For example, changing a shift point for a given gear is $100 vs changing a shift point and a pressure setting would be $200. That value can be used towards the full custom tuning price.

Shift Logic

Hi ,

Gday from Brisbane ,Australia - new member here soaking it all in !!

I am currently tuning a LS3 -6L80E combo .. NA apporox 500rwhp - engine is mafless tuned using HP Custom OS .

Everything is going well -except Im experiencing excessive trans slip on shifts at high load especially 2-3 shift approx 2000 + rpm . The trans is newly rebuilt and I have been mindful of keeping flares to a minimum during my quest to sort it out !

Shift time seems excessive for 2-3 shift and I am struggling to work out why base on tune set up . I am missing something somewhere!

Whilst reading the shift time section of your article section -there is a hyperlink to shift logic . Unfortunately it does not work and i was just looking for some conformation on my assumptions I guess.

I currently have TM disabled and will be looking to add and fine tune it to assist with trans life .

I have uploaded log and HPT file - any assistance would be appreciated .

Cheers and many thanks

Kyle
