Just got my nelson tune, help plz

[potchy]

So i just received my new pcm today, installed it, tried to start the truck and it runs for about 5-7 seconds then turns off. I tried the idle re-learn but it still shuts off. I can't seem to keep it running. Could there be anyother re-learns that i need to try?

You tried the security relearn?

It's a 97, is that a new enough computer that i would need to do the security re-learn. My truck doesnt even have a security system or the blinking light it talks about in the faqs.

Just keep trying to start it. When I first installed my tune it prolly took 10 tries before it would even idle. Then once it idles you couldnt rev it. So I just had to let it idle and have everything get learned in. Ran like a rapped ape after about 10 minutes

It's probably vats, just do the relearn from our site, nelsonperformance.com and instead of waiting for the light to turn on and off, just wait 10mins between each cycle.

call us if you have any issues getting this, we'll help out,

oh ya, vats started around '96

ok thanks, i was just waiting until the light stopped flashing and then the 20 seconds with ignition off and then starting again. Thanks though, it was getting late so i put back in the old pcm so i can get to work tomorrow and i will try it again tomorrow evening when i get off work, i'll let you know how it goes.
