E67 Questions

I've been reading through different forums where you've posted along with Tazz. From your previous post, I had already gathered that I needed to use matched components which is a good point and makes sense and the components need to be able to "Talk" to each other.

My Question in this regard is what happens when GM updates their electrical components??? Are we able to use the new components as if they were the original including using the same OS or anything else??? Just trying to ensure my thoughts are correct on this matter.

Glade to hear about the definition, wasn't sure. I don't mind paying for the program, I just want to ensure that it will do what I need/want it to do.

As far as my combo or swap goes, I have a 350 that I had built several years ago. I'm going to freshen it up adding a roller cam, new heads, use a FIRST TPI with a DBW Throttle Body. I would like to go Coil-n-Plug and use a conversion kit from EFI Connection along with one of their ECU harnesses. I will mate this to a 4L60E that I'll build with upgrades from Sonnex and a T42 TCM.
EFI Connection has both the 24x/1x and 58x/4x reluctor setups.

This power-train will be dropped into a 78 Camino that I'm starting to work on. I like all on the newer interior gadgets so I'm looking at swapping out the Dash for a newer one. This includes using more modern dash components. I would like whatever ECU I end up using to be able to talk with the BCM and everything else that I decide to use. No, I won't be installing ABS or SRS for starters. However, cruise control is a must along with some sort of VATS and keyless entry and push button/remote start.
The E67 ECU gives me both the 58x/4x and Cruise. From the info I've read online, the TBSS OS gives me the cruise option.
However, I'm not sure why a good BCM couldn't be incorporated for the Cruise Control. I know a lot has changed since I turned wrenches for a living, so I've got some catching up to do on the electrical/computer side.

If there is anything else that you need to know, just ask. I appreciate your experience and advice!!!

Greetings Camino_77

Interesting topic. I have noticed that you seem pretty set on the E67 PCM, and you gave a few reasons why, one being the subject of the crank trigger. What year is your 350 motor and does this crank have a compatible reluctor wheel with the amount of teeth that you need for this computer or are you using an external crank trigger? Also you mentioned using a 4L60E tranny. I guess I am just wondering what is special about this 350 that you want to use. You could easily drop a 4.8/5.3/6.0/6.2 in it and use that tranny and a PCM to control both and it would be much easier and alot less work and probably cheaper too. Then you could use Universal Patcher to do pretty much everything you need. Plus these motors are much better engineered than the SB350 was, not to mention much easier to make more power with these motors.

Everyone used to drop a SB350 into everything. These newer motors have totally taken the place of older small blocks and is absolutely the way to go.

BTW - You mentioned "On Base" in one of your earlier posts. I am retired US Air Force so "on base" definitely caught my eye. I'm curious about your service. Not sure if you are from USA or other country but it really doesn't matter. We all have the same kind of stories and live the disciplined life.
I've served with many other countries on my deployments just to name a few, the Royal Air Force (UK), Australian Air Force (which it's been a long time but I think Aussie Air Force is referred to as Royal Air Force too), Polish and French Air Force.

Greetings darkman 5001,

I just noticed your reply. Concerning the SB350, it's my first build. I built it while a student at the tech school that I attended for my 77 Camino which my ex-wife made me get rid of. Should have gotten rid of her instead. I have a OEM TPI setup and really like to look of it. However it does have its drawback, hence the First TPI Unit.

https://www.eficonnection.com/ has reluctor wheel kits to convert the SB Chevy for 24x/58x EFI systems.

I've also have a 56 Chevy four-door Bel Air that belongs to my daughter to Mod/Restore. I'll drop one of those 4.8/5.3/6.0/6.2 in it.

I've got some 4L60E trans cores which I'll build up. I've had experience with these along with other transmissions.

I was a Marine until injuries forced me out.

I like this build. It's different, the 350 is useable on a p01 just look for a l31 bin
For dbw you can run it but will need the tac module out of a corvette or similar if the camaro has the same mounts as the 80s cars a td 6.5 pedal out of a 90s k pickup is a bolt in part. I only had to swap one wire on the plug to the pedal from the tac to make it work. its pretty easy to wire in the cruise just 4 wires from a factory 80s or 90s cruise switch well 3 from the switch on from the brake switch. If you get the 24x trigger you can run your coil on plugs and change your timing like on the ls motors.

I want to do the same thing but 454 with a supercharger and twin tbi on top with the butterfly linkage scoop. using a p01 or p59 for my 82 monte carlo. Got the vintage look with efi. I would do mpfi but I'm worried the blower won't get the charge cooling from the fuel and have bad Detonation problems

Good Afternoon,

ScarabEpic22,

Sorry for the long delay, I had to have a couple of surgeries and I'm staring a couple more in the eye as I type.

I've been looking at different cars that I'd like the look of and that I already know their dash will fit in place of mine. Mainly the 2012 Cad CTS-V. It comes pre loaded with most of what I want including the E67 ECU. The only drawback in the TCM as it uses a T43. I do know that the E67 was mated to the T42's in some configurations. And I have read a blanket statement that the CTS-V E67's will work with the T42's although the OS's weren't addressed. Over on hptuners, I read that the T42 OS 24255281 could be used in a 2012 or 2013 platform. This same thread included a 2009 CTS-V when wired into the CANBus. I'm wondering if that's possible. If not, how would I go about determining which ECM/PCM Tunes are compatible.

Also, while I'm waiting to actually begin this portion of my project, is there a way in which I can simulate running the E67 & T42 together to check compatibility???


Boostedforlife,

I actually do have a 80's-90's GM Cruise system that I bought years ago for my 77 Camino that works off the BOO Switch.


Thanks in Advance!!!

im pretty confident you can get any gm can ecu to talk/work with any t42/t43 os cal.

It's just a matter of having the ecu/tcm send/receive the relevant data.

Tre-Cool,

That Works!!!

Thanks!!!

I'd recommend building a bench harness for the E67 and T42 to see how they like each other. When I had a ECU OS mismatch the engine torque value in the TCM was odd. (I do not remember the value unfortunately). You may need to cross your fingers with this one until you get the car running than play around with OS's until everything is happy. This is what I did.

You may need to flip the transmission model to get it to talk to a T42. You'd need to know the exact location of the trans model in your bin and change the value. IIRC T42 is an 05.

You also may be able to flip a bit in the E67 to get direct wired cruise and start requests.

If you can get me a bin file I can likely help with the transmission model and cruise locations. I cheated with the start request by copying over the whole system segment to my OS, so I do not know exactly where it is in my OS, but someone here may know where it's hidden.

I'd recommend getting an MDI and downloading the PowerPCM flasher program (located in the tools section of this form).

Sean,

Good Points!!!

I've been looking at connectors online the last couple of weeks to build a harness, These people must think the connectors are made of Gold. It would be cheaper to buy a harness pre-made. There's a pic-n-pull in Cape Fear but their inventory sucks or at least online. However, after nine years of being in the Jacksonville area of North Carolina, I've finally located a couple of pic-n-pulls in the area that might be of use. Foss it seems has some prospects that could work. I downloaded their inventory of vehicles into a spreadsheet and I've been going though it to identify which vehicles would should have the right ECM's/TCM's. Their inventory includes VIN's which is Great. Depending upon the weather, I'll go by there sometime this Friday or Saturday.

I've got files from a Late model CST-V E67 along with an Older generic T42 that I've been playing around with in EFILive. I've been able to make some changes although, I can't seem to turn the supercharger/turbocharger setting off.

I will have to download and checkout the PowerPCM flasher program. I seem to have plenty of time as I haven't rebuild the engine or trans yet. and being honest, I will not until I've had all my surgeries to fix my issues. I made a mistake and let the VA preform cataract surgery. They botched it royally so for now I'm temporally blind in one eye and my depth perception sucks. My guess is that it'll be sometime this coming spring that I'll actually be able to physically tackle the big stuff. Until then, I'm collecting the parts I'll need to dive into this when my eye is fixed.

Thanks,
Bill

I’ve been doing a lot of research here and on other sites. As stated i an earlier post, I’ll grab a whole vehicle to get the electronics out of. However, since I won’t be able to transplant all of the options, I’ll need to program them out of the BCM.

With that in mind, I’m looking at getting a Tech2. One thing Im not sure about is will I need to be connected to GM/ACDelcos’ website or will the Tech2 work independently instead of having to be connected like a J2534 pass-through???

To test everything, I’ll build a bench harness to include the ECM, TCM, and all of the CAN Modules that I plan on using.

Any advice will be appreciated.

Bill

Just my 2 cents, but you are asking for lots of problems trying to make an e67 run a sbc converted to 58x. I would just leave the distributor, and run it efi with an l31 tune on a p01 pcm from a van. Even if you have to go coil per plug, I would go 24x and stick with a p01 pcm. So much easier to accomplish this swap, and you can use pcmhammer for free.

Edit: and if you want performance, the ls heads are so superior to anything you can buy for a sbc, you should just ls swap and enjoy the benefits of better performance, mpg, and cheap serpentine accessory drive options.
