You can install the VCM software suite from the CD or download it from the HP Tuner's website. Thankfully, the setup of HP Tuners is painless.

For a base tune for 24X use a 2002 Silverado 5.3L instead of an F body as the pinned write-up did since the AC and EGR (if you keep EGR) controls are the same. The Bosch TMAP is supposedly a superior sensor to the vortec OEM as well. I have had no issues going on three years and didn't have to mess with modifying the sensor mount to the manifold. You can get a harness and repin or a pigtail and splice for the TMAP (I did the latter but should have done the former for cleaner install but in a loom looks no different) for the ground/power/signal (pins 1/3/4 respectively) to their respective MAP wires to the PCM.

The Bosch TMAP can be read by the PCM the same as an OEM MAP sensor just don't use the T terminal (pin 2). It is a 1 bar sensor but there are 2-5 bar variants that are all otherwise identical so trivial to swap. If you use the marine intake you should keep the Bosch TMAP that comes with the manifold. The better I'm able to show my skill set the more success I'll have in advertising myself at local car meets and performance shops. The area I live in is littered with military guys and retirees looking to go fast and finish their dream rides. The truck is more of a show piece to lure more business my way for performance modifications and engine building. I do understand that ease of swapping in an LS platform and I respect it's capabilities as I've done a few in the past but nothing is more interesting to me than seeing something like this in the engine bay.Įnd goal will be a forged 383 stroker, aluminum vortec heads, some type of intake and big rear mounted turbo for 20+psi of boost. I'm looking to go down this path of modifying the 元1 platform to maximize it's performance and overcome the challenges of the original design. This truck will not be used to tow so I'm not worried about that effort anymore. Once I install the 24x reluctor wheel I'll then install a GM LT1 hotcam or a higher duration cam for a big turbo build. I know these swaps have been done many times but they're isn't much hard info on both sides for pros and cons of each to plan out my next move.Īfter I install the 0411 PCM I'll see if I can raise the RPM limiter to 6K and see how the truck reacts.

I'm only interested in the ramjet as it looks to be more of an efficient piece than the marine intake. It may also be easier to complete the swap with sticking to the marine intake though.

I'm curious if they make a larger throttle body for it though as my current throttle body on my whipple set-up appears to be larger in size than the ramjet set-up.

I have a marine intake manifold but I'm also interested in installing a ramjet intake as well. I've seen a bunch of failures in the DSM community on the GM 3 bar sensors and I want to avoid that if possible. I'm going to do some research and see if the AEM 3 BAR MAP sensor will linearly output the same voltages. To run speed density I'll need to disable the MAF codes and upload the 3 bar MAP sensor file and install a 0-5V GM MAP sensor. I'll download that file once I purchase the HP tuners dongle ect. Supposedly the 98-99 LS1 engine file runs a speed density availability alongside a 24X set-up. For those interested, the 0411 PCM can run with speed density. I scrounged through HP tuner's website and found my answer.
