DCH,

Thanks for posting the image of your board.

Hi Tim Here is a pic for you, All transfer cases have a low gear ratio and when in 4WD low the speedo output has changed. So the GPIO has logic for that. your TPS should be fine the only thing I'm not sure on is engine rpm input Brad is correct in that ISS shouldn't be used as engine input. I don't...

Oh, yea, Thank you for the help. I am sorry I ment a pic of the actual board with the components soldered in so I could feel more sure I assembled mine correctly. No problem. So one more question.. what is the need for the 2WD to 4wD switch? what dost the input do? I ask because my application is a ...

Oh yes now I see the inputs for the PCM? I must be blind. Thank you to everyone who has helped me figure this stuff out. Maybe someone can send me an image of what their board looks like when it is complet so I can make sure I have installed all the components needed. I know mine might be slightly d...

Hello to all again! Maybe I am not fully understanding things yet, but in my application I plan to use the GPIO megashift as a stand alone trans controler. My existing JET TCM uses TPS and engine RPM as well as the trany inputs. I noticed there is no input for the TPS on the 4l80e build. How is it a...

Good day to all, it is cold here today, good day to sit inside and solder up the GPIO boards. I want to thank all of those who have taken the time to work through the issues and build the GPIO for the 4L80e. Anyways I have a few questions, in the build guide currently it appears engine speed is supp...

Hi to all, Has anyone ordered the 4L80E BOM through digikey? There is a few items on backorder, some out till mid March? I tried Mouser and it looks like they dont carry some of the resistors? I am not sure I dont order electronics like this that often. Anyone have any other sources or anything? Tha...

DCH, Hey thanks for the help, oh yea and happy New Year! You have really done your homework. For some reason I did not see the BOM, how did you know where that was? That BOM is a great help. I am starting to figure this out now. Last night I came up with a list of circuits I thought would need, but ...

Hello to all. I am just wondering has anyone recently gotten a GPIO board, and if so has anyone built one to shift a 4L80e trans? Maybe I am missing something all together, or maybe I am just ignorant and should not even be fooling with this stuff, but how do I determine what electrical components I...

Hey, The 93 on down force motor was operated at 292.5 hz, and was pulsed every 10 seconds for self cleaning. 94 on up uses a new force motor that as you stated operates at 614hz as well as routes the oil differently requiring no cleaning pulses at all. The new arganment allows better pressure stabil...
