I used the Superchips flashpaq tuner that Magnuson sent me.

seems like it is narrowing down to the tune or computer... A lot of you have guessed this since the start. I guess we'll see what tech support has to say in 12 or so hours :-)

 

Please dont feel like I'm talking down to you with dummy questions. Just have to check the obvious first. You would certainly not be the first to miss any of these things.

All vacuum lines been checked? The one under the Radix intake tube as well?
The MAF is plugged back in?
Was your battery fully charged when you did the PCM flash?
If you give it some gas while starting, does it make a difference?
"REDUCED POWER" doesnt appear in the dash cluster as it shuts down?

 

Oh man, I've done the MAF not plugged in thing before. Good idea.

 

I am by no means an FI expert, but is there any way he can put the stock tune back in the pcm??? JUST to see if it starts, not run it like that. Would kind of narrow down to see if the tune or tuner is the problem.

Just a thought

 

If the Superchips saves the origianl file then I'm sure he could. However, if the radix install included bigger injectors than they will be scaled wrong and it might not start. If the stock injectors were re-used, then he could try this. Just DON'T go drive it like that, LOL!

 

Oh man, I've done the MAF not plugged in thing before. Good idea.

 

It would run ROUGH and probably die anyway due to the bigger injectors flooding the engine.

 

It sounds just like what happened when I did my procharger,it needed the relearn like shakes posted. It didn't work for me the first time I tried it but the second time I did the whole process it fired right up. try the relearn again.

 

if it's not the relearn (which really sounds like it) the only other thing IF you have fuel pressure and the maf plugged in that I can think of is VATS, and xlr8nss touched on that earlier. The maf unplugged takes a second or 2 to die. Do another relearn.

 

hope you get everything straightend out...

check everything these guys posted.
