A friend of mine has a 04 SS silverado with a Radix and a 8 psi pully. He tried to reprogram the ECM with his super chips tuner that came with the S/C kit. Well some how he screwed it up (low battery), now the truck wont do anything, I had him do a relearn for the security, but it didn't work.

Do any of you have a tune that could get him going, he has a 05 ECM that I'll be tunning, we are just going to see if this will make the truck start, so I just was going to do some basic stuff in the tune ( injector flow rate ect.) I just need a ve and maf tables that I can copy over a stock 05 tune.
I don't want your tune, I know how much work goes in these thing

And shouldn't his ECM be recoverable if a superchip tune failed half-way through loading?

 

Quite possibly he got a bad box from Superchips. I've gotten one in the past and had to replace the PCM. Superchips offered to fix the PCM, but I would have had to take it out of the truck and send it to them at my expense for a week or so. No so great customer service with Superchips support.

 

I think you need someone that can activate the 04 PCM and flash in a new stock tune. Maybe the dealer will do it for you. Your superchips/magnuson handheld will need to be sent back to Magnuson and be reprogrammed. I don't think you should try to use it again.

Looks like you may have to start out from scratch on the 05 pcm. Sorry but I don't have tables for it.

Check with Magnuson anyway to find what needs to be done for sure and what they may be willing to do for him.

 

I think I have some let me look...

Ok, I found some, sent you an email

 

THANKS KBracing96!!!! I got them.

He has used the super chips programmer before, but he said he was tiring to use it to pull codes, then he said he was just going to rewrite the program.???? I guess he was thinking something might have gone corrupt.
He loaded the program and it loaded half way and died, now when he tries to load it again, the tuner said already loaded. (Why the hell did it let him load the first time?? it was already programmed.)
I told him to call superchips on Tuesday, but we are going to try another
ecm.

 

If it failded halfway through he has to pull it out then reload it.Otherwise the truck wont start..kinda like its doin now.Happened to me on my Predator before i read the instructions heh.Only my problem was i didn't remove the three magic fuses to allow it to load so it make it a 1/4 through then died....

 

which fuses?

 

you will need to have the PCM reflashed back to stock....if it did not fry it. Haveing a fully charged battery is VERY important when preforming the programming part of the install.

 

Could it fry the ECM then? It had the program already installed. Also I could not connect to it with HPTuners with a full battery.

 

Mine did the same thing when I first installed it. I loaded the original tune from the Superchips unit back into the pcm then tried the radix tune again. It took the second time.
