Newer PCMs have integrated memory that's nonremovable and as of now can only be tweaked with a tech 2, which nobody has and even then I'm told that can only upload new data packages (and no one has the capability to make new packages.)
Remember when you could just rejet the carb and put it on top of the blower?
Let us know when JC Whitney comes out with something for us. Nobody's figured out how to do N* PCMs yet, and nobody to my knowlege is working on it anymore. Sure they'll figure out crap for high volume vehicles that a lot of people will mod... but how many Caddys are there compared to mainstream cars? And how many of those are owned by old people who will never ask it for more than stock performance?Trench said:Even JCWhitney sells handheld programmers for many newer model trucks that supposedly help your performance out. Many of them even have differetn programming packages for different purpose. Towing, cruising, racing, etc.
Is there something I'm not understanding? :hmm:
Well it's the OBDII N* PCM... since the OBDI N* PCM is relatively easily reprogrammed.Trench said:Ah, so it is not OBDII in general. Just the Northstar PCM?
That is what I was missing.
Why is that, exactly?eldorado1 said:but remember your injectors stop firing around 60-70psi.
Because it's a solenoid. The force to open the pintle given by the electricity is a constant... The fuel pressure wants to keep the solenoid closed, and the magnetic force has to overcome the fuel pressure to open the solenoid. So once you start upping the fuel pressure, eventually it won't open anymore. In my experience that's right around 65psi on the stock northstar injectors.davesdeville said:Why is that, exactly?
