WHOOOOAH.. lots of questions. LOL
As far as the cluster sending and decoding the signals... he is probably right... LasVegas already gave you the best idea. Hide the other console somewhere if it is infact necessary.. my only point is that you can try it. I still don't think it needs the cluster to do anything for it, but this is nothing more than a guess on my part. The ECU does all of the translation for the data, etc. I don't think the cluster has anything different in it. The computers for the H2 and the Corvette, all LS1's for that matter are all about the same, it makes sense that GM would use the same conventions across models.. again just a guess, but could be easily figured out with a bench test.
The image does look like it is about a meter from the window. Pretty cool.
As far a tuning goes.. I can show you about what ever you need to know. You are going to need a wideband oxygen sensor to really do anything meaningful, I have not put mine in yet. All I have done is disabled the torque management in my truck, haven't messed with shift points or anything. I have tuned my ZO6 which is making abit over 600 RWHP. I bought the software with the intention of building a turbo kit for my truck.
If there is anything I can do to you help with this let me know. If someone buys the module, I will do the bench testing on it...
Anyway.. you can download those pictures right for where they are posted, just right click and "save-as"
Looking forward to see if this will work.. don't think it is something I would do to mine, but interesting none the less. I really like it on my ZO6.
Glad I could get you started. Go to
