STIM

A forum for discussing applications and implementations of the MegaShift transmission controller code for the GPIO from B&G. This can control up to 8-speeds and 6 shift solenoids (plus a 16x9 table for controlling a PWM line pressure valve). It has manual and fully automatic modes (16x9 load x speed table), with under and over rev-limit protection, and full data logging of all inputs and outputs (among many other abilities). A TransStim to test your completed board is also available.

STIM

Post by dch »

How many of you would like a STIM for the GPIO that we can use with the transmissions. It will be manly directed for the 4L60/80 modes but can be modified to use wilth other tranys. weather we can get this done depends on how many want one. Thanks Dave

trans stim

Post by Bernard Fife »

All,

I have been asked about the stim for the transmissions application. I had a bunch of these produced a few years ago, and all of these have gone out with the various beta boards.

My plan was to do a new trans stim board that accommodated the resistor based shift lever positioning, and support for the various spare outputs/inputs.

However, I have had little feedback on this, and won't do the work unless enough people are interested.

At this point it looks like there are three options:
- do nothing, and people can rig their own trans stim up on their test benchs,
- re-release the original stim board - it has support for the 4L60E and 4L80E and could be ready in a few weeks,
- re-design the original trans stim board for more general usage - this might take several weeks.

If anyone has a preference for one of these options, let us know here, and we'll use this discussion to decide how to proceed.

Lance.

All,

I have had a batch of v2.0 trans stim PCBs made up. You can read a bit about it here: http://www.msgpio.com/manuals/mshift/v2transtim.html I will be adding to the trans stim docs regularly over the next several days. Do not use the BOM - it has not been verified yet.

I need to test these PCBs (and the corresponding BOM and build instructions) over the next week or so, and then they will be available for purchase. The boards cost $14.90 to make - which is what I will sell them for, but I haven't researched the shipping yet (I expect it to be about $4 without tracking to North America, more with tracking).

The way I will offer these is that user can PM me with a request for a certain number of boards (and their full name, mailing address, and phone number), and I will send them a PayPal invoice. Once that invoice is paid, I will ship the order. Users won't need to have a PayPal account - apparently they can use a regular credit card via PayPal without an account.

Once I have a few board's built and working well, I will post full details in this thread (so please don't PM me just yet).

Lance.
