I like the hood, did you guys make it or is this a potential future product from someone.

We modified an existing product to suit our needs. We managed to cut its weight by about 35%, and installed the AeroCatch system.

stock Yaris hood is 12.75 pounds.
Those are cool latches, did you make something to hold the pins? I couldn't get them to line up.

Cool, we pulled around 8lbs off the front.

I just ran a piece of flat stock from the OE hood cushion mount to where I needed the pins to end up.

I wanted to mount them the other direction (90 degrees from what you see) but you can only get 5 degrees of tilt out of them and still have the pins engage. By putting them sideways you have a lot more flexibility, and they are way easier to line up.

Just got back from another round of tune-up and tuning. Started at Toyota HQ with a "health check" for the car, trying to get rid of our CEL for the crank angle sensor. No luck. The TSB for that only applied to 07+ cars, and the reflash could not be used on our 06'. They did test the CAS and everything was good, so we will just have to live with the light if it comes on again.

Then back to the tuner for some more dyno runs. A little more tweaking to the camcon found a few more HP over what we had at Willow Springs. Hopefully that and the new clutch/flywheel combo will get us around Thunderhill quickly this weekend.

So from what you've seen with the gains from the Camcon, would you recommend it as a worthwhile performance increasing mod?

I don't believe anyone has used a Camcon extensively with the Yaris so I'm curious to hear some feedback on it to see if it's a viable mod to squeeze out some more HP out of our car.

I don't know what one cost versus some of the more complex units, but both our tuner and myself were surprised by the gains that could be had with it - it looked like ebay stuff to me, and I expected nothing out of it. While it does lack some key tuning abilities that the higher end units offer - and we will be upgrading in the next month to something more versatile - it does make power.

I will have to fire up my lap top to look at the sheets, but I seem to recall a more than 10hp and tq difference between the unit being off and on. There are not to many bolt-ons that will make that kind of power. It works. But we know there is more in the programming, power that the Camcon wont unlock.

Thanks for the information. I've seen a lot of talk in regards to it with other Toyota engines, but never any sort of hard information, just butt dyno readings.

Checked the files, 11.1lb-ft tq and 13.2hp, on a Dynapack.

I am beat. What a long weekend and a long drive.

Thunderhill is a great track, lots of elevation changes, and really tuff off camber turns. The track was a little slow for our car, for most of the turns we were pulling out in 3rd gear just out of the power band, and shifting to fourth on the fastest straits resulted in almost no acceleration because they were uphill runs. Watching a Fiat X19 pull away from you uphill sucks. But the good part was hearing a Honda guy complain about getting beat by a Yaris.

Two more podium finishes, 3rd both days, out of six cars - and lucky to finish at all on Sunday, as the dreaded misfire came back. We believe the car is experiencing fuel starvation, we are generating enough grip and body roll with the slicks that at even 1/2 tank the car will cut under certain conditions. This happened three times during the weekend, and in all the cases the mis went away and car was good after about half a lap. Time to look at getting a fuel cell.

are you adjusting a/f, vvt or both w/ the camcon for power #'s?

VVT and fuel trim.

Just make sure you're monitoring oil pressure as well. I'm sure you know the same thing can happen inside the oil pan too.

[mojoyaris]

I have the same problem with fuel starvation and since the car is setup to run lean, after a good hot run, she just runs out of gas and is pooped. This only happens when I'm running the car 90/90 (90% of power bandwidth, 90% of the time).

Time for a piggy back, bigger injectors, fuel pump and Throttle body.

I just saw the video u posted on YT.
-When the misfire appears, does your throttle respond only if u press it lightly?
-Goes away a few seconds later?
-Does you Check engine light blink?

Sorry for asking too much but I'm having a random misfire and the car does the same buzzing sound (not too nice to hear ) when it occurs. And it happens after a long drive (1.5-2 hours) averaging 80-90mph specially when shifting from 3rd to 4th gear

YES

We think the issue is the tank/pickup, as we only had this problem in Turn 6.

Certainly a new fuel pump, one with a better pickup design could help, if that is in fact the issue.

But putting more demand on the fuel system with some of those other parts could make the issue worse.

Piggy back is in the works. We can not touch the throttle body. And we are looking at fuel cell options.
