camshaft55 07-30-2010, 11:22 PM Hey guys i recently just bought a subscription to nicks tuning libary at duramax tuner. My buddy has a 07 lmm with dpf delete and a egr blocker. As soon as i flash in a tune larger than 350rwhp the truck has a terrible bog off the line. It cleans up and pulls hard midway but is terribly slow at first. just wondering if any one else has experienced this at all. RickDLance 07-31-2010, 12:11 AM Have you talked to Nick about it? camshaft55 07-31-2010, 01:05 AM Been trying to get a hold of him all day. Im sure hes a busy guy tho superpro56 07-31-2010, 01:30 AM Does the truck have a lift pump? Could be commanding too much fuel to boost the turbo. camshaft55 07-31-2010, 01:13 PM no it doesnt. thats my guess too. in my experience u can usually get 70-100 more hp at the wheels before the fuel system is inadequate tho. camshaft55 07-31-2010, 01:14 PM what do u guys recommend for a lift pump? do i need the larger fitting at the injection pump as well? RickDLance 07-31-2010, 03:42 PM Air Dog is my favorite. I liked them so much I became a dealer for them. mikesmithdmax 08-08-2010, 04:22 PM make sure when you run the script you change all your calibration units to imperial. you have to click all then imperial not just imperial. jtaylor11 08-08-2010, 07:26 PM what do u guys recommend for a lift pump? do i need the larger fitting at the injection pump as well? Nab it ties into your OEM lines in front of the fuel cooler. AirDog has a good setup. Try shooting Nick a PM. Also do a search for logging desired fuel pressure. That be one way to check and see if that's your issue. 72splitbumper 08-09-2010, 06:49 PM make sure when you run the script you change all your calibration units to imperial. you have to click all then imperial not just imperial. I bet thats it.I just did a friends truck with the max effort tune on his lmm and it worked fine.(runs out of fuel on the top end)It still ran pretty good. camshaft55 08-21-2010, 11:17 PM Hey guys sorry i have been out of town for awhile. I will save some logs first thing tomorrow and let u guys know how it went North Maine 08-22-2010, 06:31 AM I have the same issue with the 400 tune off his tune library. Let me know what you find out. vortecfcar 08-24-2010, 09:01 AM Anybody having this issue, please try setting all of table B0795 to '1.0' and let me know if you notice an improvement. (Only LMM trucks!) Nick North Maine 08-28-2010, 10:11 AM Thanks Nick, I made the recommended changes and there is a noticeable difference. Could you or anyone explain what that change did exactly? Sorry if its a stupid question... vortecfcar 08-30-2010, 09:23 AM This table controls the fuel mixture limits with regard to air. It's how you make the truck run clean (or filthy for that matter). Problem is, you get a truck with a dirty MAF sensor or non stock intake and what was a super clean tune is now prone to cause a lean condition with makes the truck feel lazy out of the hole. Nick | ||
