Last season I ran my Dodge 8HP70 (behind a turbo LQ4) via TurboLamik and while it worked well it was never quite what I wanted it to be and since its largely a black box controller there was very little to do with it.
Thats why I was so excited to hear MaxxECU working on custom firmware for 8HP control via CAN. I already run my motor on MaxxECU Race so it'd be nice for a number of reasons.
Well they finally announced today that they're rolling out Beta testing.

Just so happens I also use a MaxxEcu Race.

Yes, but for those of who already have a MaxxEcu, there is no need to buy an additional TCU. Although looks like you might need their 8HP software update tool, don't know for sure.

I meant to ask, are these parameters definable thru TunerPro? I've been digging through it extensively to make sure all my bases are covered but I feel like you've mentioned a few capabilities I've not seen yet. It could be because I've not gotta deep enough in to tuning though.
And a dumb question - crimps v soldering, I always try to solder and heat shrink where I'm making a permanent connection. No soldering with any of the TCU components?? I'm not an electrical tech or anything, just played with a fair amount of wires, maybe incorrectly...
Thanks

Solder makes a brittle connection. Proper crimping is better in a high vibration situation--I soldered the window switch since I didn't have a crimp tool for wire that size.
As for the shifter there MIGHT be settings, almost everything seems tunable.
I'm stuck right now though
-- no one can tell me what RPM signal the tcu needs.
Holley sends a 12v square wave signal.

I am still learning the TunerPro interface, but that parameter is accessible.

So the car is back on the road(yay!)
So far this transmission is quite pleasing to drive. There is still some work (RPM signal hook up) that I have gotten word back form Turbolamik now. Lukas informed me to use the holley output so I will be doing that soon.
The only thing I noticed on this transmission is I can hear it when it slips the clutches between gears for easier shifts--not sure if this is normal. The only reason I know it's exactly that is due to watching the laptop during slow speed shifts. This is for P1 map. I switched back to P9 and 95% of that went away unless I'm REALLY easy on it.
Automatic mode isn't working currently so that needs to be figured out(or if it can be with the current shifter)
So far still super happy. Engine feels like it gained 100hp!

I have a MaxxECU race going into my swapped IS300 with a TH400. for the last 3 years I've really been happy with my setup but here recently the lack of and overdrive has really been eating at me. With Maxx getting the 8HP support released it might just push me over the edge to go ahead and do the swap. I don't think it would be too difficult aside from some clearance issues on the tunnel, nothing a BFH cant resolve though. Glad to see the ongoing interest in this thread. Question, of all the adapters out there, whos is the slimmest?

Jarred used this adapter so he can fill in the details.

I have been working with TurboLamik, for the last several month, on having full integration between the Holley EFI systems and the TurboLamik TCU. What this means is that the two will be connected with just 2 wires. This applies to the Holley Dominator and HP using V6 and also to Terminator X and X Max using V3. The Dominator and Terminator X Max are optimal because they have two CAN busses and DBW throttle.
The TCU needs information in order to make shifting decisions. Namely, it needs RPM, TPS, MAP, and torque output. Those are the basic channels that are a must, however, in order to make the transmission work optimally, the TCU needs to send messages back to the ECU.
The most critical is a signal to retard the timing during upshifts. This is commonly known as torque management and all modern transmissions implement this strategy, both for smooth shifting as well as transmission longevity. It can also be extremely helpful to retard the ignition during shifts to keep the tires from spinning during hard upshifts. With a very powerful engine, it can actually be pretty dangerous to upset the car during a full throttle upshift. This feature is now working between the TCU and the Holley ECU.
Another feature that goes along with torque management is throttle blipping on downshifts. This feature isn't strictly necessary, but it too will be available, although somewhat limited, because Holley...
The TCU will also send the following information: Gear, transmission temperature, speed, converter slip, and clutch slip. All of this information will be available to be displayed on any of the Holley digital dashes, not including the 3.5" handheld.
If there are any questions, please ask.

People have been asking for a comparison between the 8HP90 and the 8HP70. Here are some pictures that compare the two, as well as comparing the 8HP90 to a T56 and also a 4L80e.
First the 8HP90 against the 8HP70:
This is the 8HP90 against the 4L80e:
This is the 8HP90 against a T56
We are scheduled to do some TurboLamik testing with the new firmware that has full Holley EFI CAN support this coming Saturday.

As for a the slimmest I would say that Adamat/SLG is likely to give you the most clearance.. However, make sure to ask him about the plate that goes between the block and the adaptor if you do go that route. Had some issues due to not having that 1/8" plate that after putting it worked great(with some trimming).
I do like the flywheel and have no complaints after it is all said and done. The dowls leave some to be desired...but it works and my car does move under it's own power even without the RPM signal working!
