Stay tuned

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.

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.

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

Throttle position seems to be irrelevant, the engine is flat no matter the input.

It does not go away a few seconds later, takes more like a 30-60 secs depending on the severity.

CEL was flashing, but no code was stored during the Saturday occurrence. On Sunday the issue was bad enough to keep the CEL on and we pulled P0300, P0301, P0302 and P0304 - all misfire codes.

In our case this happened in Turn 6 at Thunderhill each time. Previous to T6 you are dropping down a big hill (the video does not do the elevation justice) in to a medium speed (3rd gear) right hander, then just a slight lift for the left (T6) and this is where the starvation would occur.

We think that all of the fuel is loaded to the drivers side rear of the tank previous to T6, then the lift and sudden left turn pulls all the fuel to the passengers side front of the tank, and this is enough to get the pump to suck some air even at half a tank.
