Interest in knock LED?

[InvisiBill]

I was just wondering how many people would be interested in a knock LED. http://www.chitownsyty.com/html/tech/led.htm is the schematic for those who care. About the hardest part of making a premade version for anyone to install is that you have to hook it to the ESC board in the MEMCAL. I think I may have come up with a decent way to do it on a stock MEMCAL, and it should be relatively easy to hook it right to the adapter board of an Ultimate if yours doesn't already have the knock LED.

Also, would the Ultimate users out there be comfortable soldering three wires to the right-angle pins on the adapter board (where you plug in your stock MEMCAL) for this?

The parts are cheap and it's a relatively simple circuit. However, I know that not all of you have the time or ability or whatever to make your own. Plus the shipping on the parts is much more than the parts themselves, if you only get the stuff for one. If I could make a relatively "Plug n Play" knock LED for under $20 or so, how many of you would be interested? It's not meant to replace your scantool, but to provide a simple way to make sure you're not knocking without hauling out your laptop.

Count me in, I would like to connect it to a small red LED on my pillar pod.

Sounds good. What versions of the ultimate would this work on? All, some, the newest ones?

Exactly. I planned to mount my LED in the "filler" space between my boost gauge and the flat part of the pillar pod.

The circuit ties into the ESC circuit on the MEMCAL, so it's not anything chip specific. It's just that it'll probably have to be mounted differently between "stock" and "Ultimate" chip setups. Rather than tying into the pins under the MEMCAL's blue cover, you can tie into the right-angle pins where you put the stock MEMCAL (the ESC actually) on the Ultimate's adapter board. It should be easy to solder wires onto the side of those pins, or you could use the "stock" setup and hook it to the MEMCAL's pins directly.

I don't have an Ultimate myself, so I'm not sure exactly how would be best for that. I'll look into it before I finalize anything... The newer "radar detector" Ultimates have a hookup for a knock LED. There's an LED on the "gauge" one that might be a knock LED also. But again, this ties into the ESC circuit and just blinks when it sees knock. So if your factory ECM can see knock from the ESC, then this should work.

Sounds sweet Bill, been wanting to do it for a while, just let me know if?when everything is ready.

As far as soldering, I don't figure I would mind. Got friends who know a lot more about all that than me. As long as we can still do chip tuning. If we do this, should still be able to pull the chip and burn and then put it back in, right?

I'll probably do a GP like I did with the DM cables a while back. I just wanted to get an idea of how many people would want something like this. Like I said, shipping is like 6x the cost of one set of parts...

Yeah, it would just be a couple wires hooked into the right-angle pins on the side of the adapter board. Nowhere near the PROM and hooked only to the adapter board. Or you may be able to use what I have in mind for the stock setup, and just plug it into the top of the stock MEMCAL, though clearance may be an issue with that...

i have a built circuit, but i havnt installed it because it has to be soldered to the MEMCAL. if there is a way to use the ultimate carrier instead, that would rock!

you gots instructions?

The "pins" that you solder to on the ECM run straight down to the holes on the bottom of the MEMCAL. Find out which holes these are, then solder the wires to the corresponding right-angle pins on the side of the Ultimate adapter...

The new style Ultimates, both the "radar" and gauge style have the knock LED included. The gauge style has it integrated into the display, and the radar style has the option of integrating into the display or mounting it remotely. This previous post shows both versions, scroll down to see a good picture of both...

Remember that Ultimate chip owners can upgrade their older versions to the newer ones also for $165.

Thanks for the clarification. I was looking at the instructions on BG's site and it only mentioned the remote mount knock LED for the "radar detector" version. I thought it looked like one on the "gauge" version, but I wasn't sure.
