Glad you see the value in the FIC... It really is perfect for a low boost / boosted daily driver application. Just so you know, I also have an automatic so those base tunes should be even better. Of course there's a huge list of variable that will throw off its accuracy, but it's a hell of a lot better than starting from scratch.
Things you NEED to monitor: Oil pressure, water temperature, AFRs. You also need a code reader. Boost/vac is also important, but not required. As for the tach - you don't need one but I'd recommend getting one. When you're tuning the FIC learns the signal relationship between the cam and crank sensors to determine RPMs. So while you're datalogging you'll still be retrieving accurate RPM data. As for the tC since you asked - that's running a Motec ECU. It's great and the tunability is awesome, but it's a PITA when it's giving me issues because I don't have direct access to the tune. |

Focus_Sh1ft,
What have you done to your transmission in the Yaris? Also, what about the axles? I am completely new to the idea of these unequal length CV's, so weird. Do you get lateral pull when taking off in line? How about zipping around in traffic, any pull to either side even with a LSD. The only LSD's that I can find online all seem to be 1.5's. Even though they claim to be adjustable, how do you adjust the packs for those unequal length axles? Seems like a lot of understeer to one side or not enough pack room to get the LSD balanced for the longer axle. In my Porsche, I have a set of custom made axles that use a special rod called "7degree spherical rod" for the axle shaft. This type of material will twist 7degrees off center before torsional strength even comes into play. I have dropped into first gear at 8K quite a few times in order to pull the front end up and I have never broken an axle. I was thinking about fabbing a set up for the Yaris using some of my 930 CV's. They are WAY to strong for any kind of power I could possibly get out of the Yaris unless I put a V8 in it or something. Better safe than sorry though, right?

There is no torque steer in these cars. One axle is of a larger ø so that the torsional strength is even between the two.

I had thought that one axle was longer because the transmission was not in the center of the car.

We did! I read your post and came up with something else in my head, sorry!
Have you heard of anyone breaking axles in boost'd Yaris's?

Never heard of one breakin. Even at crazy HP numbers. I don't know if caliyari is using stock axles, but I've seen echos making 250+HP on stock axles.

I swapped in fortified axles as we passed the 250 mark. Didn't want to chance it.
