it happens, especially with the age of these trucks.

i would never try and flash an ecu as old as ours when we dont have any support on the matter. our ECM's arnt even made anymore, even cummins cant sell us a new one... any time you flash you want to have some control over it and to my knowledge no one has managed to dump the factory ecm programming so there is no way for anyone to unbrick them in their garage. if we had the raw code then perhaps you could solder to data viers on the board and force a sector write back to the chips - ive done this on routers, play stations, dream casts and so on but in every case we had the source code.

your best bet is to just send the ecm out to a rebuild company and either buy a new one with trade in or get it 'rebuilt'. you may be able to find a used one at a salvage yard some where. i managed to find my new ecm for about 100 bucks but a safe bet is around 1K.

well this is a bit funny, i removed the battery cables and had it sit for a couple of nights and this morning i put the cables back in, turned the ignition on and plugged the programmer back in, it automaticlly rewrote it back to factory settings successfully and the truck now starts.
it idles great but when i drive it it starts to sputter just like it doesnt get fuel the way it suppose to. but thats just a guess.

sincerely

what year truck? did you buy the hypertech used? It could have rewritten the wrong calibration back into your ecm.

Smarty Know it all.

its an 99 cummins.
but i got it sorted out, somehow i blw a fuse for the fass lifting pump.

do i have the guts to try plugging in the hypertech and go for stage 3 or was this my last chance given before it rapes and kills my ECU?

At this point, hopefully the vp44 isnt damaged from running with no lift pump. I would confirm wiring integrity for fass lift pump to find possible short. Fuses do not blow on their own or go bad. I would send your programmer out to be repaired or tested before trying to use it again.

if it was in deed a fuse, i personally am not scared to flash.

i cant think vp44 would be bad, i only ran it for like 2 minutes and most of it was idle. truck runs fine now atleast. but i do am curious about the stage 3 on the hypertech..

Consider getting a quadzilla. They are very capable tuners and don’t flash your ecu.
