Safeguard

[turboge]

The MP3-T is essentially the same thing, but the fueling/ignition requirements will be different. My base map will get the car running but further tuning will be required for any particular setup.

E6X is an E6K with additional drivers and a built in RA8 reluctor adaptor. As much as I like piggy backs it's just a way of beating around the bush, most people end up spending much more to add independent controls when a standalone could have been had.

I do believe the J&S is a great unit to add to any standalone, preventative measures are always a great way to "Safeguard" your engine for anything that could happen.

Safeguard is in, but not sure it is working.

Basically I have to turn the sensitivity all the way up to get the light on the unit to light up. Anything less than that and it doesn't light up. With it all the way up, I can get "knock" (noise really) just by reving up the engine.

I mounted the knock sensor on one of the threaded holes at the back of the engine (below the oil filter). Thought it would work, can't actually see why it wouldn't.

So, maybe I get no knock at 5.5 psi, which is probably fine, but with the sensitivity all the way up I get some noise at high rpm, and it does not go away with any of the boost or mid-range retards in effect, so I'm sure it is just noise.

Thoughts?

Linux? John?

Yeah, with the sensitivity all the way up I know my forged pistons register. Not sure in your case. Like when I start it up, and start driving...while the pistons still have a little expansion to do, my knock monitor will go off a little. After that, it's fine. GM accually recommends that the knock sensor be mounted as low as possible on the block, away from the rotating mass asymbly. Mine is mounted in the front, just above the oil pan and MBSP.

 

[Little Beavis]

Mine is in the back, but it is actually pretty low. Basically right between the passenger side axle and the block.

Linux, abuout how far is your sensitivity turned? Also, when do you see knock? I know mine is way to sensitive, but I don't get anything if I turn it back down. But that means good news in theory. I run an MP3 ecu, with a fmu, 93 octane and about 6 psi, with no knock then. (I am still running pretty rich though, so that is helping to reduce any knock as well. . .guess I can lean up the FMU another step and go from there. . .)

I guess that would mean it is time to turn up the boost, huh? (laugh)

 

[John at J&S]

What about your mid-range retard? Also, do you have the TPS modifier hooked up?

 

[Little Beavis]

Don't have the TPS hooked up, but I can easily do that.

I was getting no knock, so the mid-range wasn't used.

I've since changed the FMU. I'm a little leaner than I'd like, but still "okay" but now I get lights coming up. It looks like the mid-range needs to be more. Should have left it at 0,2,4,6. I still have more testing to do. The TPS should help as well, so I'll hook that up too and see what happens.

 

[John at J&S]

(drinks) Yea! Lights! Action! camera?

no pics of of broken pistons, please.

 

[Little Beavis]

Well, I know it works now. . .
I tried to lean up my FMU again, but it went too far lean and the J&S started lighting up like a christmas tree. . .engine is still good, and I've put the FMU back the way it was!

Very cool. I'm happy.

turn up the boost to 7psi....

and talk about what you see.

Im still venting my wastegate pipe, so theres is no way i can hear ping/knock. And Im afraid on loosing my engine again.

I know you have a bit more of advanced timing, but, i just need a warn from you people using the J&S.

Little B, what plugs you using?

 

[Little Beavis]

I'm running the cooler plugs from the spool kit and an inline pump. Did you get a new pump yet?

It might be a little while before I can get you some answers, I'm trying to re-do some of the stereo stuff right now and my whole dash is ripped apart. Plus, I figured I'd work on a few other things. . .never done working on this damn thing.

 

[LinuxRacr]

I run 8 PSI on my MP3 right now, and the J&S works beautifully. I use the extended reach plugs from FP. I forgot the exact code...here it is: http://www.flyinmiata.com/store/prodinfo.asp?number=04-56200&variation=&aitem=1&mitem=1

They say they saw a 5 hp increase on the dyno with these.

 

[Little Beavis]

Linux how far is your sensitivity turned up? Where do you have the boost retard set (start and amount). Very curious, as I need to up the boost now! (laugh)

 

[LinuxRacr]

I have my sensitivity up about half-way. I also my boost retard I think starting at 3 PSI.

 

[Little Beavis]

I'm at 7 psi now!


(laugh)

very nice. . .
I'm still running rich and with the J&S sensitivity way up. But I only got 4 degrees of retard to fire at that level, so I switched my mid-range retard to 3 degrees and tada. . .no knock retard. . .the J&S is kicking ass. . .

I have the boost retard pulling about 1.25 degrees of timing starting at 5 psi, so I'm not even pulling that much timing (less than 6 degrees of timing at full boost and 4-4500 rpm). The thing is pulling good now. . .(big smile on Beavis's face)!!!!!

 

[LinuxRacr]

See, I can't wait to get my re-programed J&S now. Should be here soon.

 

[igdrasil]

I wonder how bad is knock on our P5's turboed...

You guys really stress me out...can decide on which unit to with:

Prefworks Piggyback,
Haltech, or
J&S


Both 1st and 2nd unit does not protect for knock but works timing and fuel.
3rd protect for knock, controlling ignition timing, no fuel control

Beavis...how much you paid for the unit and the monitor?

 

[LinuxRacr]

I love my J&S, but the piggy back is still in my future. I will use both together.

 

[Little Beavis]

The J&S will always give you a "safety" net even with a piggy back. I do not know that any piggy back is set up to do what the J&S does. I'm happy with it.

I would guess that since I'm running the "advanced" timing and having little issue, that the regular protege will be better and might not even have an issue (no one seems to know how much of a timing difference there is between the two ECUs so this is just speculation though).

I did find out that if I bog the engine bad (boost at real low rpm in fifth gear, the J&S will light up. But shift and go. . .and you're gone without any lights. . .so it might just be set a little too sensitive, but it is not surprising that it does this. . .the motor is pretty loaded up at that point, so it probably does knock. Oh well, gotta find some more time and do some more driving.

John never sent it. He's probably slept since then.
