So ive had the sct for over a year now with no problems, ive always had it on the 93 octane tune but I recently lost my job so today I decided to install the 87 octane tune while I was filling up to save a few bucks at the pump.

Well I filled up hopped in and started to retune to 87 as ive done a few times before. I went through the whole procedure you know; turn key on, leave engine off... Ect. It powered down came back on, started writing the tune, it got to about 70% and just turned off, and turned back on.

I knew something was wrong right away, usually the tuner makes a congradulations tone! And say tune successful.

So I contacted sean powell right away via email, he reply within 20 mins! And told me to try to disconnect the battery wait a few minutes a retry.

Well after several attempts I decided to call my friend with a cummins to pull me home.

So now I contacted sct tuning a asked them to help me, and send a recovery file,

So what do you fellow sct users think?
Did the tuner fry my computer?
Is there a cheap fix?
Also where can I find a cord to connect my tuner to my pc? All I have is usb devices and no plug that matches the tuner.

Thanks
David

Oh yeah the truck cranks over but its almost like theres no fuel.

Diconnected the 3 main plugs at the computer and it does the same thing.

Almost as if its not picking up the pcm.

My brother has a 01 parts truck that has the same motor trans and 4x4 do you think I could use his pcm to get by for a couple days?

I dont see how a tuner would fry your PCM. If it is something cause by SCT i would hope that they will help you out cost wise.

Well it only cost me $20 to have a buddy pull me home, I did it not to long ago for him at the same price.

I just found a pcm for a 99 5.9l 4x4
For only $40 would this work?

Just wondering, what kind of tuner do you have like do you have a link to the product? I am looking at getting one, sorry it's off topic..

How do you like it, otherwise than this problem you are having, did you notice alot of power difference.:icon_steer:

Not as much as I liked

From what Ive read on other forums it can fry your pcm sometimes the recovery tune works sometimes it dosent.I used my printer cable to load tunes to the tuner.Hope it works out for you.

Yeah Im gonna get a ride tomorrow to buy the cord.

Which plug is it the one on the bottom of the tuner or on the top?

The plug on the bottom.I dont know what the one on the top is for.I guess Ive been lucky changed tunes in my R/T several times and no problems yet.
