Tony, what is happening between between 5.5-6K rpm? The line stops then takes back up again? What is going on with the torque curve? It doesn't look smooth and varied quite a bit from run to run?
I'm not entirely sure... I think it was losing a signal from the wire. Here is a graph vs MPH as indicated by the dynomometer. I had graphs of each printed out should there be an issue comparing the before vs the after on one or the other.

As for the torque curve, I think that has a lot to do with my craptastic worn motor mounts.



I did this my my RMM on my old car (before it got totaled.) It definitely helps, and it's a happy medium between suck and poly. That windshield weld is pretty thick stuff even before it sets, so I'd advise anyone using it to have a decent quality caulking gun ( I bent the handle on my cheapy just squirting the stuff into the mount). I believe 4 days to cure is probably conservative, as I gave mine 8 hours and reinstalled it. I did let it set for 24 hours before driving though.
I've noticed a huge difference in the pliability from the 24 hrs after filling the mount, to 48 hrs, and now at 72 hrs(just checked) it is basically solid.

Stock with no filling you can twist the mount by hand with relative ease quite a bit. At 24hrs you can tell only the outside is cured as you can still move the mount pretty easily and watch the stuff stretch. 48 hrs it was noticeably stiffer but when poking the window weld you can tell it's not quite 100% cured... and just checked at the 72hr mark you can feel it's stiff as it will probably get, and doesn't feel gooey at all when pushed with force. You can barely flex it by hand now except when exerting a lot of force on it.

I think 3 days is probably about right. Doubt I will see a difference tomorrow but will report if I feel otherwise.

My main reason is aftermarket mounts = $$ and I don't have the time to bother fabbing my own, though I MIGHT go that route for the RMM since it's very simple to do. I could even just make a big empty "hole", but a sleeve for the bolt to go through, hold it all in place and fill the space with window weld... making it my own bushing. Actually that sounds like a pretty darn neat idea... it will only cost about $20 in materials at very most. :lol:

i'm going to do the same thing with JB Weld and see how it turns out. i looked on their website and the breaking points are way higher than anything it would see in this application
JB Weld is going to be MESSY as hell... I hate the stuff personally.

Are you changing classes - the 'work' you did to he motor mount is not HS legal.
Yes, I've been running in STF since event #2 this year. The ECM tune is not legal for HS either. I look forward to see if it's a really noticeable difference this weekend.

Don't recommend JB Weld for this application. You need some flex to allow the engine to align itself, and I'd be concerned about breaking the aluminum portion of the mount.

Well, ended up not going to the event today because 1) I was out late last night with friends and just overall tires from the work week and 2) it was an 80% chance of rain/thunderstorms at the event site 1.5hrs away... and it was my first Father's Day and decided I wanted to spend the day with my wife and son instead. Seemed kind of silly to stand around in the rain all day to drive my car for 5 min on Father's Day.

On another note, the motor mount got installed yesterday, feel a few minor vibes at idle, more noticeable with A/C on but overall not bad at all. Nothing like my Jeep was with poly motor and trans mounts. If you have any experience with them, it's about comparable to a PT Cruiser at idle... those pieces of shit vibrate damn near no matter what you try to do:chuckles:

And when I inspected the mount, a small bit of it squirted out from the center. It was not 100% fully cured. If you look to do this, let it cure for a full week IMO. My old mount was actually not broken(surprising I know), just super pliable probably from the age of it. I may just clean it off and fill it as well to have a "spare" and swap out to refix my brand new mount. FWIW it was the front of the mount that stuff squirted out from... which means it was in reverse(engine torques BACKWARDS when going forwards) or it was under engine braking(or bad shifting... ha). It still very stiff and feels 100% better than before. You can tell there is some compliance in the mounts still when launching or taking off, but the level of mushiness is about what you would expect to be for a stock vehicle(any vehicle other than a Mazda3 that is).


And my wonderful wife got me an air compressor for Father's Day... woot woot!




30 gal cast-iron oil-lubed belt driven 110v Campbell Hausfeld was $400 at Tractor Supply. This thing is infinitely quieter than my dad's oil-free compressor ever was. I've basically just done the break-in procedure on the pump and checked the tank over for leaks and ran my 1/4" air ratchet to test it out. Going to change the oil in the pump tomorrow and carry on.:coolio:

Happy Father's Day to you sit. This is technically my second, but I spent my first 600 miles away at work.

Thanks!

Ohhh man.... Nice compressor .... The only way IMO... Awesome

Thanks!



Anyway today I finally got the time to wash and wax it... looks gooood again.







Here is a pic of my other mod that should lower my PAX times by about 1 second...



Here are a few pics of my filled motor mount:



And you can see the little bit that squirted out... doh. Let it cure for a full week before using! Luckily this is on the front of the mount, meaning it only loads that side when in reverse or engine braking.

You're really reminding me about now just how badly I need to polish and wax my car. The paint has so many fine scratches in it, it looks like the PO rubbed it down with a scuff pad.

Oh the joys of the automotive ignorant and automatic car washes.

Yeah I'd been putting it off for a while. My front clip looks horrible up close. The hood has a billion little chips too... stupid Mazda paint.


Looks good from 5ft though :)

Lol. This.

My buddy who drives motorcycles told once you wreck or lay your bike down, it's never the same. Also he told me you can never get it looking good again, but you're golden if it passes the 50/50 rule.

If it looks good at 50 feet or 50 miles an hour, no one else will notice. ;)

Autocrossed this last weekend. Did okay. The lot we ran at really sucks with all the loose crap on the surface, it is on a large slope, and the start line began with a right turn up hill... awesome conditions for a low powered open diff FWD car :eek:oh:

50/60 in raw time:
http://cincyscca.com/wp-content/uploads/SoloResults/2013/PE5/pe5_raw.htm

36/60 in PAX time:
http://cincyscca.com/wp-content/uploads/SoloResults/2013/PE5/pe5_pax.htm

Here's the overall results, I'm the only one in my class:
http://cincyscca.com/wp-content/uploads/SoloResults/2013/PE5/pe5_fin.htm

I was just short of 2 seconds off of Dave Rudy(the really damn good Mazda3 driver in HS in the Tire Index class)... on a short course like that it is pretty bad.

It was a really damn confusing course as well, I had a DNF first run out as I got lost toward the finish... the next two runs were spent trying not to screw up, then my last few runs I just had a hard time driving the whole course consistently... there was a stupidly tight Chicago box that would punish me every time.


Tires would help too :eek:oh:

Will post some GoPro videos whenever I find the free time to upload them.

Here are some pictures that the club photographer took of my car. First pic is from PE#1, second is from PE#5.






Not sure if there was any camera trickery... but looks like the wax made a huge difference :lol:

Ha thanks!


I'm delving into trying to figure out my P0138 code. Likely the rear O2 sensor, but I'm going to try and verify it's not a wiring problem before I blow ~$80 on a sensor.

Also currently awaiting the final tune from Dynotronics. Should be getting dyno'd again in the next few weeks if I get it and all is good.

So...you're not booked for the 27th this month for a dyno?
No. My last email response from dynotronics was June 17. The only other response was in the Dynotronics thread when I was told to email them... which I did Sunday(July 21). I am waiting on them.

Because I am not "paying" for the tune I'm not expecting to have super fast responses as I know they are buried with other stuff and paying customers... so for that reason I am not going to waste the dyno operator's time to come in on a Saturday(they do this only by appointment) by scheduling when I'm not positive it will be ready and safe.


I DO have an autox test and tune event on Sunday... I don't know how the format will be run(how many runs and stuff) but I MAY try to load the stock tune after getting baselin

So my bad... Test and Tune was Saturday... Sunday was just a "fun run" event but I ran it and definitely had the fun :alaugh: The course was great, were were running on the airport pad... it was perfectly flat concrete with not a single obstruction on the whole pad. It was a BIG course... the National Tour is being held there next weekend, I might go and watch for a few hours but I didn't enter, nowhere near ready for that yet.



Anyway w got 7 runs, I had one DNF, one was a +1, one had a nice spinout and my last run of the day was fastest with a 71.388. John Souder has a fully prepped HS(on street tires) Mazda3 and ran a 67.693... so I'd say since my car is basically stock on all seasons I'm incredibly happy with how I did. I finished 40th in PAX in STF, if I were running the HS-T index I'd be 34th. I keep an eye on overall PAX to try and track my progression.


The ECM tune really helps with the throttle response mid-corner and in slaloms, it's more instant rather than like you have a sponge below your foot. Also more torque off the line, had no problem spinning the tires all the way in first gear to redline, before the tune when I've launched(on much less grippy surfaces mind you) I'd get off the line spinning but it would catch grip before reaching redline, sometimes to the point of bogging if you launched at too low RPMs, but usually it catches grip and slows a tad.


I'm uploading the videos to my computer now, I'll put them on Youtube over the next day or two. I never did do anything with my videos from the runs at Turfway park, I'll have to add one or two of those as well.



Here are the results:

And here's a video... this was my run #4... was going so well until I spun in the first slalom... it was a good spin too... first time I've ever completely lost it in this car.


And here's my 7th and fastest/final run of the day:




Also all seasons do NOT like concrete one bit:

Fronts:

LOL! That was a good one; totally saw it coming too (unsure if you could have driving) but as much weight transfer as there was on that slalom turn right before that.. it got a bit hectic and then shifting all that over again it seemed pretty obvious what was going to happen next hahaha

Fun (safe fun) either way!

Yeah... I knew that in many of my runs I wasn't pushing the slaloms as much as I -could- have so figured I'd try and not hold back at all. Turns out they do require some self-restraint :chuckles: I knew what was going to happen but I really didn't expect to lose it completely... I think that in a slalom when trying to countersteer while taking into account that if you don't go between the cones you get a DNF had a lot to do with it.

The car got progressively looser as the day went on(or more grip in the front). Notice on my fastest run how I backed off in I think both of the slalom sections... didn't want to lose it completely as otherwise the run was pretty decent overall... and I was right in that it turned out to be my fastest run.
