Coding help needed for Jeep project - will pay!

Hello, I am working on a custom Jeep project that I did a late model GM LS6 engine in. I like my projects to be very clean and look as though they were built at the factory. The challenge I have is to create a simulated cam sensor signal using an existing crank signal and feed it to the jeep processor so that a diagnostic trouble code is not set so that the cruise control is enabled. Yes, all this just for cruise control! I have purchased a propeller project board that I intend to build this "cam sensor simulator module". After spending some time reading and trying to understand the programming... wow... I am overwhelmed, so I thought I would ask for help. I would like to hire someone to write the code for me. This crank signal that I will use as an input has an amplitude of 5v and frequency changes as engine rpm increases. The cam signal is also 0-5v and has to be timed with the crank signal. See the waveform I posted. I have an excel spreadsheet I would share with anyone interested in helping me that explains in much more detail what I am trying to accomplish. I tried to attach to this but it looks like that file type is not supported? Please post if you could help a car guy out!

    What does the existing crank signal look like? Are you wanting to use the raw crank wheel signal (58 teeth I think) or a signal emitted from the LS6 ECU? For that matter, what ECU are you running the LS6 with? Please send me that Excel file - mrobert at injectoranalytics.com -.

    Just wondering, have you checked out 150Tunes.com? They can reprogram the ECU for you. and like the name says, the price starts at $150

    TC,
    I did explore that avenue but not with that company. Several people told me that they could remove some DTC's but not the critical ones, the cam signal DTC being one of those. I will check in with who you suggest, thanks for suggesting! That would be the easier solution if it could be done.
