Jeff's DIY turbo build

[06YarisRS]

Wow! What progress! This is a true diy build. Amazing what you've done. I am away from home atm, so can't see the pics as well as I'd like too - small cell phone screen. I was at a car meet of sorts last evening and spoke with many knowledgeable folks. I think my decision to move away from the AEM F/IC is pretty much solidified. Although my car runs well, I want better closed loop fueling control. However, your lamda values look really good. I see 0.82. Is this at full throttle boost or partial throttle? I'm really anxious to hear how you make out with the FIC. I spoke with a tech at ECUMaster, and it seems that I can run one of their standalones along side my factory ECU, having the car's ECU control everything other than the engine.

Again, super impressive build. I think it was very smart to add the turbo coolant lines. I was lucky, in that mine burped fairly quickly.

Edit: I am still on the stock Yaris fuel pump and have good fueling right up to full boost. It was the first thing I asked my tuner about. At Wot (when the car does go into open loop)and about 7-8 psi, I read 11.5:1.
