JS11 internally pulled low? Launch switch input
Hi,
Trying to get the launch switch to work with beta8 on v3 board, but nothing makes sense - built the circuit with two protective diodes (one from JS11 to +5V on the proto, one from JS11 to the switch, switch tied to ground). Diodes checked OK.
The problem is that nothing pulls JS11 high - with the diode to +5V, the voltage there is .17V (between JS11 and the ground). With a pull-up of 2k2 the voltage is 0.22V, wtf?
[the JS11 was selected in MT as the launch input during measuring, TPS was over the launch threshold]
Same situation when tried with JS7 and JS10 (tried with just the diode, not the pull-up) - nothing pulls the port up.
What am I missing?

Thanks,
Tom

No problem, here is it.muythaibxr wrote:You might not be missing anything, there could be a bug.
In any case, can you post your msq?
What about this piece of code (ms2_extra_init.c, function main_init(void), line 374) :
Code: Select all
if (pPTApin0 == &dummyReg) {
conf_err = 7;
} else {
pPTApin0 = &dummyReg;
//need to configure as input and setup pullup
}

For me too launch do not work on js11. As I understand I have no hope to get it working until Saturday?
Some of my instalations:
VW TBI, VW 16V 60-2,
BMW M50 COPs 60-2, BMW M20 and M50 ITBs as Alpha-N, BMW M20 turbo Wasted spark
Opel 20XE Wasted Alpha-N with ITBs
Audi 10VT Audi20V
MR2 3S-GE.............
and over 100 tuned

Did you try any of the other input in the drop down box in megatune while hooked to js11?
I ended up changing my setup to this

And it has worked with both 7 and 8

Just try. JS11, JS8, JS7 do not work for me. It is on 20010812 version.
Is some indicator for launch control in Megatune? I see three empty cells between other indicators.
Gints.
