Hey everyone, first time posting here so forgive if i step on toes or otherwise circumvent protocol. Interesting proposal for you guys. I have an 07 5.9 with some goodies, ran a Smarty for quite some time. Decided to make the switch to EFI Live, so far it hasnt panned out so well. Going on a year now and still have absolutely no tunes that are really useable. My tuner has been working with me to try and resolve the issues but so far we have come up with nothing. He is to the point that he is suggesting my ECM is failed. I am not really buying into that as my Smarty runs like a top all day, every day, doesnt matter which tune. I recently had a CSP5 file bulit by my tuner, I updated firmware and bootblock, loaded files and ran truck. On the tow tune, runs well, fairly happy with that, switch to street tune and it starts kicking and coughing and smoking very very badly....thats at idle. It sounds like a very heavily cam'd 12 valve with a ton of timing. I Cant even get it to start on the other tunes. What I am proposing is this. I have 4 logs from my truck, would anyone like to have a look at them and see if there is something we are missing? I am told that the logs show the truck commanding a very large amount of fuel at idle(70mm3) on all the logs....but it doesnt run poorly on all the tunes. Anyone up for a challenge? Yes I started with a clean file, not a Smarty stock, actually tried 2 different stock files.
