I have an L31 with the 14097395 ramjet 350 cam in my S10, mostly everything is working fine. I have a tune cobbled together from a wonky mail order tune, and stumbling my way through the editor to get it running alright. One of the last things i am trying to get right is my TCC lockup. Sometimes it decides it wants to work, and sometimes it doesnt lock up. I plan to get a professional tune done on it once i get better heads and 1.6 rockers on it. I ran a data log of it working, and not working. The one of it not working, i did not have the TPS channel selected to gather data from. If this is not enough information, what other channels should i add to see what is causing the TCC to not want to engage. Attached is the 2 log files, and the current tune i am running. tcc good.hplno tcc.hplNew Test 3-29-25-dtc.hpt
