Just wanted to add my "keep on moving forward"!
You are doing FINE work, so keep it(the work), the posts, and vids on youtube coming. I'm sure I'm not the only one taking it all in.

How are you doing the computer? We are looking at hptuners and efilive for a programmer for our sc gtp swap into an 85 Fiero.

I would recommend that the OP use HP Tuners to tweak the program as there is a long history with that software. It takes a while to learn how to use editing software but if you add any mods, having it is essential.

Thanks! The above post is correct, I have a friend with HPTuners. James L Brown (who manufactures 3800sc swap harnesses) also programs the PCM for you.

I have been subscribed for a while, I love the videos, they are very informative. When I saw the part about the A/C compressor, I was laughing because I did the same exact thing torquing the nuts to 74 ft-lbs because of how it was described in the list of torque specs. I pulled the threads right out of the compressor bracket, I ended up tapping to the next size with the same thread pitch and using a Time-Sert. Glad to have you and LostNotForgotten giving tips with the 3800 Supercharged install, it definitely helps many of us a lot. I hope you get over 1,000 subscribers soon, you definitely deserve it. Keep up the good work!

AustinH,

Thank you for the updated video. I am in the process of getting all my parts required to perform my 3800sc swap and I have been watching your videos and “LostbutNotForgotten’s” videos. You guys are my inspiration and my guides in doing this swap. I can’t thank you enough for sharing the information.

I have a 3800sc Series II L67, but I’ve aquired a Gen V M90 and L32 lower intake manifold.

Do you know is there any VATS or PASSKEY on the Gen II that needs to be disabled in the ECU? I’d like to test run my engine before I mount it in the Fiero.

You are welcome! Glad to hear.
Yes, there is VATS you must disable. You can do that with a programming tool like HPTuners. I have a friend handle all that stuff for me. If your harness came from Danny (Canada) or James Brown, then they would have disabled it already. You can send out your PCM to one of them or take it to a shop to have done otherwise. What are you doing for a harness?

I wasn’t sure if I should try to use the existing harness and splice into the Fiero wiring or try to get a harness made. The harness is really the only thing I am missing to perform my swap. My engine is from a 1998 Grand Prix GTP so hopefully its not too challenging. What are your recommendations? I pretty handy, but I’d be willing to buy one too save me some headaches...
