Well today i was told that is my tune thats the issue, my VE map is not right, and my power enrich is not setup correct

I still dont think that has anything to do with it but im not a professional tuner by any means

 

found this under system

"alt F term" it has a 1 on it, i wonder if that has to do with charging system


here is more info on it

If you could post screenshots of those tables, the FIC data and the data you entered in your tune, I could help you out. I've tried to open your tune but it won't download for some reason.

 

i cant paste exact numbers, when i enter them its like it rounds it to the closest number

also i found this thread

going to look see if mine has that on the neg cable or not if so i may just unplug it

 

Based on your offset table, your injectors have a slow response time. I thought those injectors were faster. Post up your data for them that they came with. My Alt L Term and F Term has a 1

 

i already posted the data here in the thread, its a download link cause the forum wont let me load it in my post

only 05+ trucks got the RVC systems, im just trying to figure out if there is a way i can disable it and make it sit at 13.8 as if it was in a "fail mode" cause i have the feeling trying to tune around the voltage change is going to be a bitch


link for injector data
it wont let me attach the excel sheet so heres the link

You don't have the ammeter clamp on the negative cable? Should just unplug it and be done with the wandering voltage. I think the only downside to this is that clamp also has a backup battery for the radio/presets in the event the main battery runs dead.

 

i dont remember ever seeing anything on the neg cable, im going to look after work though. From what i read some is a deal on neg cable, others is done by computer

 

ok so i did have the plug on the neg cable, unplugged it and stays at 13.6v, however that leaves my battery light on

 

Time for an custom autometer gauge cluster
