Trans control release 1.0.0

[jsmcortina]

To announce the release of the 1.0.0 version of the Microsquirt trans control.

There's a minor ini tweaks and some manual updates since RC2 only.

This is available from the Downloads Page http://www.msextra.com/downloads

Enjoy!

Up and running on this firmware and everything looks good. One thing to note however, the 4T40E uses a 31 tooth reluctor wheel for both ISS AND VSS. No 40 tooth reluctors at all.

Is the ISS before or after the overdrive gearset? On the 4L80E it is downstream so the slip calcs have to take that into account. For any other transmissions it is presently assumed to be true input shaft speed.

ISS is most definitely before the OD gear set

Hi James,

I have just modified my GPIO to add the paddle shift circuits. At the moment I don't have the paddle shifters, so I have just set it so that when the Paddle analogue input reads zero it is to activate the horn. Problem is the horn output doesn't activate. I have check all my circuits and they are all fine.

I'm using PE0 as the enable input active low, AD5 as the input with a pullup resistor and PM4 as the horn output. I used my multimeter to check the PM4 output and it doesn't switch, I even tried changing the output to PM5 but that also didn't change when pressing the horn button.

I had a quick look at the code and I think the problem might be in the IF statement for the horn output. The "then" and "else" terms are both the same.

Code: Select all

// +/- 0.1V
            v_low = pg4_ptr->paddle_outv - 20;
            v_high = pg4_ptr->paddle_outv + 20;

            if ((paddle_v > v_low) && (paddle_v < v_high)) {
                pad_mode = 3;
            }

            if (pin_paddle_out) {
                if (pad_mode == 3) {
                    *port_paddle_out |= pin_paddle_out;
                } else {
                    *port_paddle_out |= pin_paddle_out;
                }
            }

Attached is my MSQ.

Cheers,

Yes, clearly a cut/paste mistake. Will be fixed in the next release.

Hi James,

I had another look at the code and it looks like the horn output will only work when in paddle shift mode ie the paddle enable grounded. The horn output should work all the time.

Cheers

Daniel.

i ran into an issue trying to setup on bench for gpio. it may be ini related but i couldnt find anything
i started with base msq
changed to gpio
4l80 already set
then tried to set inputs for options.
set manual mode input = adc6 it wont take, it reverts to adc0
set padlemode enable = pe1 that works
set paddleshift input =adc4 reverts to adc0

.29 allowed this
rc1,2 and release did not

[jsmcortina]

Please post your MSQ and I'll try it out.

only 2 settings away from default but here it is

[ashford]

i did a workaround on this. i loaded .29 ini file for the project, set the 2 parameters i needed and then reloaded the 1.0 ini into the project and it works on the bench.

[jsmcortina]

I replicated this. TunerStudio doesn't like some changes I made to the ini file and silently gets it wrong. I've made a workaround for 1.0.1 due shortly.
