05 lly questions
 

i have a 2005 lly and i bought the truck with a chip in it, is there a way to set it back to stock without flashing the computer, would buying a new programmer or chip(idk if there the same thing or not) would reprogram it with no problems. i like the extra power, plus a little smoke when i lay into it but would like to be able to adjust it for mpg.

anyone have any ideas?

if its got a flash tune in it and you dont have the programmer youll have to take and have ecm reflashed. then you can buy a programmer and install a new tune

well thats what i needed to know thanks, i dont know what it is i bought the truck with it from the dealer. i wish i didnt have it, id like the extra mpg now and then, is there a way to find out what it is

where would i have to go to get my ecm reflashed, and whats the cost, and risk?

gm dealer, itll be whatever their labor time is and Id say theyll charge an hour, just a guess tho could be less.

:tu:ok thanks your information has been very helpful, i am a diesel tech but im more used to bobcats backhoes and old detroit diesel stuff of that nature, im done several ford injecter jobs as well for my shop here in missouri, but i have always been a fan of the duramax just havent ever had to work on one. but thanks i have a couple of other questions if youd like to answer them all info is much appreciated.

no prob. diesel tech here too. more into the performance side now but, I am factory trained d-max tech, worked on them for two years at local chevy dealer.

:tu:ive worked on a 1996 24v cummins several times for a guy down the road from me and keeps returning and says he likes my work its a farm truck but i put injecter in it and lift pumps fuel pumps seals pan turbo on it, but once again ive always been a fan of the duramax just havent ever had to work on one lol i do still all my own work except the whole ecm stuff on these newer diesel engine:tu:

i got a stupid question, i never thought of it till now when theres a winter storm brewing here in missouri in my area right now, my trucks and 05 2500hd and i havent looked where the block heater is located? and is it controled by some sort of thermostat or timer or will it hurt it to plug it in all night?
:humm:

depends on how cold it gets if your truck is equipped with the cord its on pass side either fastened to the positive batt. cable or on top of the frame rail. theres no timer or thermostat most people i kno that use them leave them plugged in over night though.

thannks again millerboyzdiesel appreciate it :tu:

im wanting to do some exhaust work anyone have any ideas?:humm:
