Hey guys if your still having trouble dialing in a 270 or 274 cam. I have tuned the 270 and 74 vvt with good results. You do need to disable ANN as this will cause the idle to hunt operating within its parameters. If you need a base VE table let me know since the one stock is crazy. For idle its all in the TB air flow model raising the first 3 cells by a lot of you need an example let me know I’ll send you a base file from a good running cammed 6.4 that has only headers and a CAI it’ll get you close. Now the cars will auto drive or throttle hang this is taken care of in the small range tb air flow. Spark gets shifted to put the sweet spot in the lower vacuume area and make the other tables match. Most guys are locking the VVT when doing this cam install. Let me know if it’s locked or limited you need at least one or really bad noises happen as valves hit pistons.
You will also want to raise the shift points as the power comes in much higher. If you don’t it will feel boggy. If you need these changes I’ll be happy to update your tune file with them just post it up and let me know.
I would like some help with mine, I have it doing alright. Have only messed with vvt lock pin and idle and my fans. It?s running decent but I know there is a lot left to do
I opened the file without problems, I am using beta
do you still have thatntune ?
I have a 18 srt was a 6.4 car i have a 5.7 hemi 274 comp cam 3"exhust 308 gears shorty factory srt headers installed for now while my new motor is being built I'm new to tuning been trying to fix a idle problem i can get it to run and idle great with this tune for about 30-45 min of drive time then it will slowly start hanging it will idle up from 3mph to 20 once the car starts rolling and will hang around 1200rpm till it gets under 3 mph any help would be appreciated i cant for the life of me figure out this problem i bought a tune off Dave at b&g tune shop and it wont hardly run at all with that tune I know I'm over looking something any help I can would be greatly appreciated
thank you GHUGGINS that helped tremendously I will work on fine tuning my ve tables now I just tried the tune and did a vcm scan I think it will do good when I get the ve dialed in thank you very much for the help again
No problem ;)
I didn't do it in that tune, but you might also want to look up a 5.7 11ish truck tune and grab the lower airflow values out of the tb airflow table since the cam shouldn't require or flow anywhere near that much air anymore at idle. This will help your TB model to better control things...
Thanks again ghuggins for the help i will check that out on the truck tb airflow i got the ve dialed in pretty good last night should i tune on the timing any more or do you think its pretty close
If your running 87 you could still add some more in, especially in the lower rpm off idle to full load areas. If your running 93 - well she could take a lot in certain areas and even a decent chunk in wot areas. Just keep in mind timing needs to transition and blend table to table, so try to make some of the same changes to the main 3...
