Completely understand, and that would be awesome.

If your talking about my thread hijack, I can't remember if it was in the tundra swap thread or another, but a different member said he was working with someone for different springs and was waiting on them or something but I asked if he knew the factory rate, and said it was 230lbs. Where that came from, I don't know. But seems like it could be fairly accurate given the rest of the system.
As long as the factory spring doesn't have any abnormally crazy measurements, we should be able to locate aftermarket springs fairly easy. Worse comes to worse, I'll eventually just buy one replacement coil or buy a salvaged one to disassemble and have tested. But for that price, I can get two brand new aftermarket coil over springs and roll the dice too. Eventually I plan on just increasing coil rate 100lbs/inch or so to deal with my front bumper, and eventual winch. Will probably do the same in the rear too.

It is CANBus. We have swapped a number of components between LC and LX without being able to get the codes not to show up. We have not swapped an instrument cluster but not really sure that is viable. We can't figure out what module is telling it to look for the AHC inputs. We need someone that can talk CANBus to work out what needs to be done.
Did you measure fender to wheel center before lift, in N for example?
Looks awesome!
Inst cluster is fine the more I think on it. I had to deal with canbus on a GM E38 DBW to chat with a arduino uno I had to control AC requests and cooling relays.
As long as the CAN lines can be tapped somewhere near the main brain; you can record the traffic since CAN is untargeted broadcast messaging. Then while recording all the traffic (its not a very high bandwidth protocol) one could test the AHC functions, and throw a switch to disconnect the AHC and record that. Further, there may be a simple "are you there? Ack/noAck request" and you flood the frames consecutively. Its been 3 years since I played with canbus programming so im hella rusty.
Yes itll be tens of thousands of messages a second, but it can be filtered down. From that point; a simple arduino module can be installed and spoof as the modules.
Over on a few bimmerboards: a guy named Thaniel helped advance this ball mightily on GM to BMW canbus chatting and translation.
This was always my prevailing idea so long as Toyota didnt gate keep behind an odd protocol spec. Hunch is no oddness based on "ignorant" the overall car reacts to missing modules.
I talked to mt4x4 on this. They commissioned a module for the 100 ahc. To get it updated the programmer was in five figures just to get started. Wasn’t going to be commercially viable. If we shareware it that could be interesting. I reall6 like the abc, but for the very long term it would be good to have some options. Ecus don’t last forever. Globes might increase in price, etc

Will you be able to snake the hard lines out without destroying them? Could be good info in the event someone needs to change on in the future.
