Finished the 411 swap

[Super_chevy]

Here is the end results, it was pretty simple finished up in about 2 hours. Fired up ran perfect, minus the code for crank relearn. Did this about a week ago. Taped it up today while waiting on head to get back from machine shops to finish up cam swap.

0411 is nice to have and do. Kinda suprised people still do them given the newer PCM option available.

I have been swapping to the 2005/2006 Blue/Green connector 1 megabyte PCM with the GMT800 Mexican L31 tune for a while. Nice to be E85 compatible.

Nice! Are you wiring a switch for the tow/haul mode? I think the Express vans have a momentary switch somewhere that you can maybe make work?

So which one do you recommend? The newly acquired '98 I have needs to be done. Thanks

I was going too. However I’m not really worried about it anymore, because I’m going to get my truck dyno tuned after the cam swap at which point I don’t see tow/haul mode being effective

I don’t know what the wiring looks like on the blue/green. It’s really personal preference how often do you fill your truck up with e85? Other than that there is really no difference

No COS though, boo! I believe you can E85 the 512 red/blue by starting with the appropriate Suburban tune and segment swapping/COS your way from there.

Is there an option to work with cable throttle body and 58x crank signal by chance?

HP Tuners supports speed density, 2 bar and 3 bar map sensors with that operating system.

Really? Do you know the OS off hand? If they support it it's likely EFILive does. As it turns out, they ripped off a bunch of EFILive COS stuff.
