New serial protocol / MS3 pre1.1 alpha codes 12+

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
I seem to be having some troubles with test mode in Alpha 14. I'm playing with some Nippondenso pencil coils from a 2.4L Honda Accord (3 wire smart coils) and so far I can't get them to fire. It may be that they need the external transistor mod like VAG coils but I can't even get test mode to fire my LS coils. Maybe I'm doing things wrong so here is how I have been using test mode.
Open the test mode dialog box
enter 12345 in the top box, hit TAB key
fuel pump off
test mode coils
coils on
single coil
coil H (the denso coil I am trying)
3ms dwell
Burn
As I say, even if I switch to coil A which is one of the LS coils that runs my engine I get nothing. And yes I cycle the key before trying coil A
Thanks,
Jeff

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
Will there be any support for Mazda 3/6 2.3L with 6 tooth cam wheels (Maybe 4+2 cam setting)?
Re: New serial protocol / MS3 pre1.1 alpha codes 12+
Sorry, I just found out that the 04-05 Mazda3/6 cam profiles are the same as the Zetec (36-1 Crank, 4+1 Cam). Thanks for all your hard work James. Being a junior programmer, I know how frustrating writing code can be!

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
I've added 'A' for backwards compatability for the next alpha. It is advised that newserial be supported by devices if possible as all transactions are error checked, the old serial method had numerous weaknesses.kizzoalfa wrote:Than as I understand the Single letter command A is not supported. Do you have any plan that it will work in the future?

That could be a problem indeed.

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
Can you add support to invert the tps signal? My car has drive by wire and the signal is 5v closed and 0v WOT.

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
Are you sure there aren't two? From what I've read it is typical to have one forwards (0-5V) and one backwards (5-0V)NArcher wrote:Can you add support to invert the tps signal? My car has drive by wire and the signal is 5v closed and 0v WOT.

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
I tested all three wires. There is one wire (+5v), (GND), and (5-0V). I tried testing in multiple combinations, but I could not get 0-5V. Is there a way to modify the code for this? I will test again tomorrow to see if I can get the correct signal. Thanks

Swap the 5V and GND wires.

Re: New serial protocol / MS3 pre1.1 alpha codes 12+
this *may* not work. depending on the design of the TPS itself - on BMWs, if you wire it backwards the sensor will not give a stable reading. Perhaps because of an internal diode or something else..jsmcortina wrote:Swap the 5V and GND wires.

I would swap the leads but I'm running

I guess I would have to make an inverter circuit.

Thanks James, I'll wait for Alpha 15 and check it again.
