Dual-Speed E-Fan code $0d <-- I have formatted/commented text file, just not posted (yet)

It's dual-fan _OR_ dual-speed code for 7427 (I run my 4l80e with PWM-TCC on $0d), though ny primary design intention was for taurus dual-speed e-fan. I have a prettier commented text file that I haven't "released," but I should probably upload it somewhere... along with 4l80ePWM_$0d patch & calibration notes. Maybe later, heh.

Modding for $0E shouldn't be too involved, just need 2 timer addresses and change the memory addresses for CTS/mph/etc..

But then, why $0E? I ALSO have a hack posted up to run 4l80e on $0d with the PWM TCC. It's a 13 byte patch, plus some tinkering with "undocumented" calibration tables if you want to make use of 2nd gear lockup (I need to grab my notes from other laptop). I've been running 4l80e for over 10,000 miles (DD)..

Anyway, sent you a PM. Give me your email so I can send you a copy (it's 12kb, forum limit is 10,000 bytes).
Helo,

Sent you a P/M back , thank you .
