Stand alone tranmission controller

[buddrow]

Hello gang,

I am currently building a transmission controller initally for the 4l60e/4l80e transmissions. More trannies will be added as demand arises.

The unit is based on an Arduino board with the required driver hardware all enclosed in a neat little box, aside from the external inputs. These i inputs will consist of a vehicle speed sensor and use either a throttle position sensor or a map sensor, leaving it up to the installer to decide if they want to run a vac line ot install a TPS on their vehicle if not originally equipped.

If there is any interest in testing a unit please lemme know.

Currently I am writing code and look to have a working prototype or two in the next 30-60 days.

Anyway, just putting this out there. More information will come as the project inches closer to fruition.

Thanks for reading,

Buddrow

i had a guy call me on this today i was looking at a 16128420 16196390 tcm to do it tunercat had the tdf done already for them to burn a chip. I was looking at the wiring to it has the same info you posted a vss a tps and a map

Ill have to take a look. Either way I am carrying on with my project. So if anyone is interested...;)

fyi this is currently a non profit project but depending on demand and success it may become "commercial".

i'll follow your progress, sounds interesting. lets see some code!

Steveo,

I'll try to get some preliminary info up this weekend. Since it's based on the Arduino platform it's written in a C/C++ compliant language and right now is pretty rudimentary with a ton of "if" statements lol. I am interested in how much user adjustability people would be interested in. I.e. you want to raise line pressure or alter tps/map vs vehicle speed shift patterns. I have considered, initially, the use of a three position slider switch to choose from 3 levels of operation, since not everyone is comfortable writing code. But I am always open to suggestions as I wish this to be as user friendly as possible.

well, it's an arduino, so ensure you have a defined data section, and have a tunerpro xdf that alters the tables/constants in all of your patterns, and your customers could just load the altered bin. wouldn't be that hard. just think "im building an ecm here".

i could help you with that part, i'm not bad with c for embedded platforms (never had an arduino though)

It sounds like an interesting project. If you can make it work, using a MAP sensor instead of a TPS sensor could be handy since that would be easier to install.

If you expect much commercial success then you'll need to have it fairly adjustable. You pretty much need to have the ability to alter each shift curve.
