Thanks Bruce!

Joe,

Sorry, I dropped the ball on this one. I will email Bruce right away and ask him to respond with his thoughts here.

Lance.

All, Marc has pointed out some input circuits had inadequate protection. In most cases this was due to the removal of the 1.0K resistors inline with the processor pin necessitated by the internal pull-ups (see above) which cannot have significant resistance in the path or the pin will never go low. ...

Joe,

I don't. I'll ask Bruce, though, he is handling the production details.

Marc has caught another error. There are two tables listing the Amp connections in the MShift info. One showed swB as pin 6 (which is correct), the other listed swB as pin 5 (which is actually the 2/4WD switch). The wiring diagram was also incorrect as swA should go to pin 26, not pin 5. The build i...

Marc noticed that there was an error in the above - The copmponent labeled R38 should have been R48 (now corrected). Thanks Marc! (The build guide was correct.)

All, In the absence of complete info on the TCC lock-up feel solenoid functioning, I have added a TCC PWM general function to the code. The LUF function is selected in MegaTune under 'Shift Logic Patterns/Configure Lever Type and Clutch Outputs/Spare Port Usage' where you select 'Use PWM2/Amp32 for ...

All, I found a problem in the build instructions and BOM for those targeting the 4L60E. You need to add 330 Ohm pull-up resistors in R22 , R84 , and R85 . This isn't done if you are using a pot style manual gear lever sensor (ex. Ford), but it needs to be done for digital style inputs (like the 4L60...

Here's bit more background info I dug up at http://www.patentstorm.us/patents/7104273/description.html : The present invention relates to the field of hydraulic circuits within automatic transmission systems and, more particularly, to a replacement torque converter clutch (hereinafter "TCC"...

Marc, Thanks, that's good info. I still need to sort out the logic for the LU Feel. Things like: - is the LUF solenoid on at all times, or is it active only when the torque converter is locking? If so, how does the ECU know how long it takes to lock the converter (for example, does it have a table s...
