    Thank you. It's been a blast to take large groups out on the lake and still be able to get to skinny water hunting grounds. My tune hasn't changed because it's too much work to swap the exhaust to...

    It works. I?ve been running it for the past 3 years. My tune hasn?t changed and is super rich but it is an extreme hassle to pull off the wet exhaust and run a dry exhaust so I can hook up a wideband...

    Once I get the tune the best I can I will post it so that it may help others trying to do a stand alone application. I'll probably have more questions before then but for now I'm taking a few days...

    Thanks to all, especially Steve.

    First outing with the family after the conversion. We went to Harding Lake, Alaska. A Beautiful day!!!

    Supercharged a 2007 2.4l LE5 GM engine from salvage...
  5. Back to the drawing board

    Unfortunately I had a setback. Ironically while cleaning up wiring and installing a marine fuse panel to make sure everything is protected the hot wire from the battery touched a bolt. That bolt,...

    Thank you. That's helps a lot.
    Who I got the base tune did tune the VE tables with a similar setup as I have just in an off road vehicle. They must be much closer than what I had before because I...

    Help needed.

    It is running great as far as I can tell. That is until I start going over about 3,200rpm then it suddenly goes lean and starts stumbling. Going back to 3,200rmp or less and it...

    I didn't realize the O2 sensor wasn't working. Swapped the WB for a spare O2 since I couldn't budge the original O2. It worked much better and the motor ran much more smoothly.

    Once the manifold...

    Thank you Steve for sharing a tune.

    I finally got it running. It is super rich but the tune I used was set up with different injectors (but 42lb like mine).

    I had to take a break. The boat went to the shop for its transplant and they need the motor.
    Do to travel I may not be back at it for 2-3 weeks. I'll post more when I get back to tuning.
  11. Thank's Steve. I did seal everything off. I...

    Thank's Steve. I did seal everything off. I looked again and the blade looked closed. I started wearing earmuffs so I could tolerate taking a better look (straight exhaust is pretty loud with your...

    I forgot that I had to rewire the IAT to the Bosch 2.5 TMAP which would read post s/c temps. Because of this I missed that I didn't have a temp reading when I reverted back to NA.

    I think I might...

    Getting discouraged. The past several times I tried to start the engine wouldn't run. It would fire briefly then die.

    VSS tables seem to be all over. The only thing I could find to change was...

    Adding some more info.
    The throttle/pedal position seems a little odd. I added a quick log of throttle/pedal movement with engine off since I can't come close to adjusting it while running.

    I am...

    And a video of it running. It actually sounds smooth. Applying a little throttle and it seems to run OK.

    So, here is my attempt. It ran horrible but at least ran. It idles around 3,000rpm. I can't find any vacuum leaks which is easy since I only have vac lines for the fuel pressure reg and boost bypass...
  17. It runs!!

    OK, I'm sure someone that knows how to tune might be embarrassed with this tune. I'm just happy it actually ran. It ran like garbage but I didn't expect much. At first I tried finding some forced...

    Thank you so very much. I'm lowering max rpm settings to 5,000rpm. Likely I won't even be able to go that high so if it does something bad happened or sucked in a bunch of air into the pump so I want...

    Thank you. Even though not an encouraging post for a non-tuner like me it at least helps me focus on what I need to learn or do. It sounds like I may need to find a way to route enough intake to...

  22. Help with 2.4l LE5 Supercharged going in a boat

    I am putting an LE5 from a 2007 Pontiac G6 donor into a jet boat that I'm converting.
    I am in Alaska and don't have anyone within a couple hundred miles that could potentially help tune this.

    I...
