Knock module for MS3 (beta test)

Re: Knock module for MS3 (beta test)
Anything I should do in particular atm since im currently building my ms3 msx combo to prep for this unit? I'm using the msx for all my fuel/ign outputs so my Fidle and native fuel and spark on the ms3 board are empty. The led's are setup as per the instructions.
Re: Knock module for MS3 (beta test)
If you have not dedicated D14 D15 D16 (LED output circuits on the MegaSquirt board) to drive other outputs, you should be able to add the Knock Module at any time simply by soldering the module in place with the jumper wires and the associated wiring from your knock Sensor(s) to the MegaSquirt.TTC wrote:Anything I should do in particular atm since im currently building my ms3 msx combo to prep for this unit?

Of course (duh) given as well that you are running MS3 firmware that supports this particular module since it requires special comms on the processor SPI bus to talk to the module.

Re: Knock module for MS3 (beta test)
I want to keep some spare DB37 pins open for when the knock module becomes available.
How many DB37 pins should I reserve?

Re: Knock module for MS3 (beta test)
Thanx, I assume the other side of the sensors would be connected to ground.

My calendar says August 2nd. Any word on the boards being up for sale Matt?

Re: Knock module for MS3 (beta test)
What are the chances of these working well with an OHV type engine (eg. Triumph, A/B Series etc)? If these modules work despite the engine having quite a bit of valve train noise then I'd love to try one in my Spitfire 1500.

Re: Knock module for MS3 (beta test)
Any further word on supply of these?

Re: Knock module for MS3 (beta test)
From what I hear, the test car they were using to verify the changes on the chip is broken, plan "B" is in the works. Guess I can wait a little longer for verification and quality.

Re: Knock module for MS3 (beta test)
According to DIYAutotune's Facebook page the knock modules and real time clocks should be available for sale at the end of this week or early next week.

Re: Knock module for MS3 (beta test)
Good news!
Re: Knock module for MS3 (beta test)
Count me in for an order. I am going to install, wire, and configure this as soon as I can get my hands on one so I can do some datalogging at a track day the end of the month. I have been fighting det problems in my race car all year so this should be big for me.
A couple questions - Is there a recommended sensor? Or, Matt, will you guys be selling them? If not, I'm going to make sure I have two on hand as soon as I can get them, I can probably just get a generic sensor from RockAuto. Also, trying to think through this, if I want to trigger an external indicator light that indicates when knock is getting detected, would that be possible now using spare outputs?
A couple suggestion based on the screenshots and what I've read here. I see windowing based on RPM and MAP, but not TPS. I am running Alpha-N, so adding in a TPS option would be good, if not done already. Also, individual cylinder retard would be a nice option in the future.
Thanks for all the work on this, hoping to be a production tester very soon...

Re: Knock module for MS3 (beta test)
We have been using a broadband Bosch knock sensor ourselves, but one tuned for a particular engine could potentially be beneficial. We aren't selling knock sensors at the moment but may add them in the future.BCM wrote:A couple questions - Is there a recommended sensor? Or, Matt, will you guys be selling them?

Trigger it when KnockRetard > 0.Also, trying to think through this, if I want to trigger an external indicator light that indicates when knock is getting detected, would that be possible now using spare outputs?

Re: Knock module for MS3 (beta test)
Thanks Matt. Is there any reason you couldn't use two sensors on an I4 engine, or is it just not necessary? I have a good spot I could mount a sensor between both cylinders 1/2 and 3/4, so was wondering if it'd be beneficial to do that...

Yeah. This engine knocks at idle with Original ECM.
Two sensors on one bank - you have to use time frames (wrong wrote) and trigger the signal according the cylinder which works (you have to run full sequential that the MS knows the cylinder 1) and you have to prevent for interferences. When you have a overlap of the signals (at high revs).
It's more difficult to use this. Or?!

Re: Knock module for MS3 (beta test)
How would one know what/which knock sensor is suitable for a particular motor if it never came with any knock sensors.

Re: Knock module for MS3 (beta test)
You could either run a broadband knock sensor or a narrow band sensor from an engine with the same bore size.Mhm wrote:How would one know what/which knock sensor is suitable for a particular motor if it never came with any knock sensors.

Re: Knock module for MS3 (beta test)
How about knock and EGT control? I just bought an EGT+ CAN board from jbperf. If knock retards the ignition EGT will rise and more advance/ more fuel will be good to control EGT. How will they both (knock/ EGT) interact?
Is it possible that knock control will also use "over fueling" to get control of knock?
Is a wide band knock sensor capable to detect knock in all rpm ranges? Which kind of knock we talk about?
And what about knock contol on boost?
