How can I monitor damaging effects on engine?

MacGyverGTP · Post by **MacGyverGTP** » Sun Jun 06, 2010 3:18 pm

I have a heavily modified 2006 Mustang GT
Running forged bottom end & close to 16psi Supercharged boost.
I've got her custom tuned with my new Trinity and now I would like to monitor if there are any variables that can damage the engine such as knock or if I am at the limit of what my fuel system can deliver.
What variables can I monitor (specifically) to show these things & how do I interpret the numbers?
Detonation is my #1 concern.
Thanks so much for any info.

Check for any Knock related PIDs, ideally the should be at 0 all the time...

When connected to a scanner with live data you can read the knock values for the two banks separately in real time.

If the thing reads all, then you van monitor the value either of voltage (this value is after the amplifier/interpreter stage of the ECU or the knock sensor controller if there is separate one) or of interpreted value - I remember something around 4-5V and additionally you can monitor spark advance correction due to the input from the knock. This is with scanner at dyno shop... the Trinity should return the same info if it reads all OBD data?

Thanks for your previous post back to my question regarding how to read the knock sensors, however the PID's I found in the Trinity to use were Knock Count AD and the number fluctuates all over the place.
Here is a Screenshot of what I am talking about:

How do I interpret this? Is there actual detonation happening?
Can I see where the threshold is where it starts retarding timing & by how much.

Thanks so much for any help here.

The last time I read a thread on this... I'm sure someone wrote about a threshold value and anything above would mean a prob

Someone will have the answer. I too need the info as my readings are hitting 1000 at times. but usually <450

DrDax, My numbers are reading the same... I guess I don't understand how a knock sensor works. Seems to me if there is any knock... That would be bad. I wish someone could answer this thread with something that makes sense to your average user.
I have seen it as high as 1200 under full throttle.

It's been several years, and still I don't have an answer on how to monitor knock retard on my 2006 Mustang GT with The Trinity tuner. Can someone provide me some direction on how to log/monitor knock retard please.
Seems this should be pretty easy with such a comprehensive tool.
Thanks,

well there is not real way to actaully watch knock on a 06 gt. the sensors on those engines are terrible and 99% of your custom tunes are going to shut them off anyway. the best thing to is get a wideband gauge and wire that into your trinity so you can watch AFR in real time. aside from that there isnt much you can watch that would help you with WOT tune issues. other than you can watch actaull timing values. on a 16 psi 3v with 93 octane, depending on compression, you would want no more than 16-18 deg or so at peak boost.

DiabloMatt, Thanks so much for the reply, and for the suggestions. Do you know of a way I can tell if I am maxing out my fuel injectors? I have a boost-a-pump... but no idea how far my 39lb injectors will take me on the boost scale. I'd hate to drop the pulley size too far and lean out on top. Not sure if fuel pump duty cycle is the one to monitor.

I was also able to hook the trinity up to my laptop and do some live logging and found out there are many more pids available on the dataviewer application, including a few for knock.
I'm afraid to detune the car just to update my Trinity. Go ahead, call me a chicken... haha

Thanks man,
Sean

16 psi is quite a bit on 39# injectors. most i have ever go out of them was about 500 rear wheel hp. which on a 3 valve is about 10 psi so you are very possibly out of injector already. i dont believe that pcm will let you want pulse width so your next best bet is to wire a wide band in and see if its starting to lean out up top. i would suggest larger injectors at that boost level jsut to be sure. but this of course would require you to retune the car.
