I'm confused, but I admit I haven't been following this build closely. What good does this PCM do you? I thought the 0411 was THE PCM to have for us?

Not if you want a 6L90E and the newer GenIV engine management.

I have been running a P59 for a while too. Better than the 0411.

Some TBSS owner out there is probably not happy with me. Managed to snag one of the last NEW GM E67s for a 2009 TBSS. It was cheaper than a reman given the core differences and me not having an E67 core.

What made you go with a new E67 setup over the E38? I'm just curious because my 2011 Suburban and the 2009 Denali donor both used an E38 ECU for the 5.3 in my Burb and the 6.2 in the Denali.

I thought I was going to have to get new connectors for this as well at $25 each. E67 and E78 share the same physical connectors, just have to repin the 2016 E78 van harness for the 2009 TBSS E67. The Molex connectors are the same though.

The 2009 TBSS still used the standard GM cruise control switch and has the standard GM VSS output for the speedo and abs. Plus the TBSS runs my PWM fan clutch.

Ok thanks for clarifying that....I have my original black box with factory toon :-D

About to place another order, to make my Gen1 SBC speak GenIV LS. If budget allows this month also ordering a Summit 8800 204/214 @ 0.050 on a 112 LSA roller cam, matching Summit branded Morel lifters and 0.100 longer pushrods. While I have the 383 opened up for the reluctor change and all the wiring striped away, I am putting a smaller cam, new Morel lifters and longer pushrods into it with hopes it shuts the valvetrain up and gives me a smoother idle and a lot more low-speed torque. 38.5* overlap on the 8800 cam vs 61.5* overlap with the current cam should change its character noticeably given both cams have the practically the same IVC and thus Dynamic Compression Ratio.

You gonna have a 411 in the loop for the factory gauges?

Not needed, nothing in the current P59 ties to the gauges on my 97 except the speedo and charge light. The TBSS E67 has a VSS output and I believe a battery light output.

Kinda off topic, but I saw that the Terminator X is adding support for the 6L80/90 in the next release. Probably a lot more money than what you have in your setup though.

I am not an aftermarket EFI ECM fan at all. Only one I have used on a vehicle was a Dynamic EFI EBL and it was a plug-in replacement for the factory TBI computer using most of the factory TBI computer circuits.
