now i am going to have to try out my bad ECM and see if i can get it back to life again

Thank You

your ECM is probably fried but try disconnecting the batteries first and unplugging the ECM for about an hour of two and try it again. make sure you have all acessories unplugged and or fuses pulled...

No it must have the same OS as the original one

Yup fried ECM from what i can tell from here. the same thing happened to me twice the first time i had to replace the ECM the 2nd time i was able to do a full system reflash and get it to work again.

Yup and i went through it with Dan but im just guessing its in my tuning and i need to adjust my idling tables.

i put that PPE pump on that you helped me with the wiring on. i turned the pressure down all the way it helped but it didnt eliminate it.

i have the same issue with one of my tunes but i only get a lopy idle when its cold out. so i got a lift pump for the truck and that made me have a lopy idle all the time.

i have this same issue about every third time i upload a tune that i created. it tells me that the ecm is locked and may be damaged. i have been able to do a full system reflash and get it back to...

but when its below 70 out the truck runs like a raped ape but above 70 its a gas guzzling 4 banger so im thinking it has to do with a temperature sensor or timing tables with different temp settings...

i got the same problem but with a yukon denali short and it is like a gas guzzling 4 banger i need to do something with it

ill have to give that a try im not so good with computers

i got to do something with my laptop its so slow i think im just gonna add more ram to it. do you have any other suggestions
