2018 Camaro zl1 tuning

[Eperformance]

Hey guys

I have a 2018 zl1 camaro in for exhaust upgrades and tuning, I haven't tuned an LT4 with the 10 speed yet.
Unfortunately i live overseas so the TCM locking procedure is a bit of a long process, and was wondering if
tuning the ECU without touching the TCM is an option? Or with these being a torque based system both need to
be tuned together to get optimum results?
What issues would i run into, tuning only the engine ecu?
Thanks in advance

so far on my 2017 a10 flex tune I am seeing a drop in how it is shifting. light loads it has gotten worse sort of draggy on light load shifts. Wot its not a quick either. So off the tcm goes to get done. As it was I didnt like how it was shifting stock and now worse with a tune in progress.

tcm tune won't fix the e85 slow shifts, you need to fix your torque model.

I had read that the e85 model will be off. I liked it over and looked low but so do the normal ones so wasn’t sure if should start by throwing 20 percent at it or not. Is there a way to log anything to make changes on it? Car is lazy has hell on the small e mix more at part throttle then wot stuff but that is down too.
Thanks Higgs I know you spent tons of time on your own c7 so sure you have it figure out as read up a lot on your stuff.
