    L31 v8 in S10 TCC Issues

    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

    I wouldn't think that cam would register misfires (false) but as a test max out all the misfire tables and see if the problem goes away. 196/206 but the 109 LSA might cause a little lopiness.

    Ok, anything others regarding trans pids. I can confirm it was physically in 4th gear at least.
    I will keep it with me and capture it next time it acts up. It's almost 50/50 weather it decides to work that whole drive cycle

    If the private message includes any cost for tuning, I recommend the original poster check out the previous post history before paying any money to anyone on here to decide their level of experience. If they were a total novice 1 year ago, they probably aren’t ready to charge money to tune. If this isn’t an attempt to get payment, why not post any help on here.

    That’s fine but the PM thing is usually people that end up asking for money that really aren’t qualified to charge. Or a straight up ripoff.
