Now that Intense has there PCM out, is it much different than the GM Reflash? And if it is is it better or worse?

 

The Intense reflash is better for making power and worse for keeping warranty.

 

Whats the differences between the two?

 

as far as I have seen, the intense stage 2 and gm stage 2 put about the same hp with the exception of the intense kit putting out slightly more tq. When you get into smaller pullies the intense kit is obviously better for being able to optimize the system to accept the higher performance part

 

Couldn't tell you specifics. I know the Intense tune is geared toward maximun power output while the GM tune is much more conservative to ensure they don't get many warranty claims.

 

it is only conservative to the point of passing emmissions and other regulations. So to that point it is tuned for max performance up to that point for the parts installed.

 

Also for emissions legality, which is VERY important for manufactures to follow. Which is a benifit if your state or local regulations mandate emission inspections; CA.,NJ,PA., Denver, ect.

 

Is the Intense PCM basically plug and play, i know you have to do a relearn, but the PCM is just like the stock one, no cuting and sattering, ect.

 

Yes it is plug and play. It is a retuned factory computer just like the GM Kit.

 

Cool thanks.

 

On the Intense website about theire PCM, it says that the Supercharger Torque Management eliminated. Ive never even heard of this. Does any one know what it does?

 

I believe this is referring to the stock GM programming will back off boost under specific conditions; 1st and 2nd gear limited to 10psi as an example, or cutting off boost under abusive conditions.

 

oh i see. but my with just the pully went to 15psi in all gears, with out the boost bypass mod. it never leaked any boost out.

 

That's because you have the Intense PCM.

 

Im talking about before i had the Intense PCM. My car never leaked any boost out. I always ran 15psi at wot, with only a pulley. I was told that the car would leak out boost after 6k do to the bypass but mine never did, it held it all the way.

 

Same here. However, I still have the by-pass done and really I can't tell the difference. Funnt thing is that ever since I got a smaller pulley and one range colder plugs, my P0171 code has never come back (it's been about 3 weeks). The car runs better then ever - no erratic RPM at idle and no bogging out of first anymore. I think the plugs are the main reason for this - not bad for $7.19 huh!!

 

Dose the Intense reflash raise the rev limiter? And if so to what RPM?

 

The rev limit is set to 7K

 

yes it does, to 7000

 

has any one seen any dyno's of the intense pcm to compare to the gm reflash.

 

My car is going in for inspection/emissions, when I get my Intense Stage5 pcm back.

It better pass emissions, otherwise I don't know what the f*ck I'm gonna do!?!

 

Here's a Question, would GM have any way of telling that the Intense reflash is on there?

I'm also assuming if you take your vehicle in for warranty work, and they decide to upgrade your PCM software that you'd have to go back and get it reflashed by Intense again.

 

Thats true, i didn't really think about that. And if you told them not to mess with your PCM then they might get suspicious and check it out. But on the intense web site it says that the PCM is undetectable by a dealer. So could they really find out.

 

if you keep your factory settings saved away as a backup assuming the intense kit works in this manner then a dealer should have no quick direct way to see if the settings were changed. BUT like many applications or software, there is an initial boot log for each install. In the case with the car an initial log should theoretically be loaded if the car is turned on after the battery died or just some simple power loss. The computer would search for its default boot log and load the settings specified from the initial launch and this may be where an issue can occur. Now I am not positive that this is how it works but it is normal as far as software applications go.

It would look like this,
initial startup :: Car initial startup log settings - saved and is only modified to save boot logs after the car is turned on successfully. future boots come from the updated file

new file created - done initially by the pcm on the car updated settings file saved and constantly updated

You would create a backup file from HP tuner software
HP tuner software would modify the updated settings file and this is where the computer would load all your hp glory when you turn on your car

Now lets say your car has an issue. You load your backup file and go to the dealer. Without digging into the computer too far or even suspecting anything they simply try to fix the issue. They fix this issue you go home then load your modified file. So they shouldn't see your modifications.

But let's say your car has a real serious issue and they take more time checking it. In theory with more time and more diagnosis they may stumble on information about the modified pcm settings since the initial boot log was always saving the modified boots. Hm?

Now I am not saying that this is actually what happens cus I have never seen the software or how the pcm is updated. But srt killer did bring up a good point and hopefully some of these tuners can shed some light on the issue

 

What if you were to keep your original pcm and just pay the core for the new one, so if any thing serious does happen than just switch the two out, do another relearn in your driveway, so than there is know way it could void your warrenty. right, sounds good.
