I'm still debating if I should get the ecumaster before I go dyno tune it. They charge 800$, don't want to go more than twice there; once for stock internal tune, 2nd time if if I ever decide to build a forged internal motor.
Still having issues with my tune, it was fine until I unplugged the battery last week, and now, none of .cal files seems to be running good.
Nonetheless I'm still going to keep this yaris project going, I've found another yaris rs, with no rust for 1100, two summers ago, and a c60 transmission from the scrap yard.

Looooong time no talk. How are things? Been enjoying my car this summer. More driving than wrenching. haha. I received my dongle a couple of days ago. It unlocks ECU Flash so that I can have my remote stock ECU tuning session with dynocenterpr. A buddy of mine from Instagram has been after me for a while to do this. He had his boosted xD stock ECU tuned and I guess it's great. He had all kinds of issues with the F/IC and had this guy tune it. Guess it runs like stock, but nice and rich in boost. He's running 9.5 psi and a friend of his 13 psi on the stock 2zr with zero issues apparently. Check out:

Great news, nice to hear from you. I've been busy, still daily driving the rusty turbo project, I'm overdue for a real tune, I might try them, it seems like the best solution! Let me know how the remote tuning session goes.

What is this dongle you speak of??! Please do tell...

How has your summer driving experience been with the turbo project, and are you considering the remote tuning session with dynocenterpr for your boosted xD? Also, for those intrigued, can you share more about the dongle and its role in unlocking ECU Flash for remote tuning sessions?

Sounds like a really fun (and ambitious) project, and you’ve clearly done more homework than most people who jump into a turbo build. The 2ZR should handle 6–7 psi just fine with a safe tune, especially since the Lotus runs boost from the factory. The biggest things I’d keep in mind are heat management around the turbo (blankets, shielding, protecting ECU and lines), plus making sure the fueling is solid—an upgraded pump (DW200/Walbro etc.) is cheap insurance compared to risking a lean condition.

The auto trans is the other weak point. While the U340/341 can live around 220–230 hp if treated gently, I’d absolutely consider a cooler to extend its life, and stick to the respectful driving style you mentioned. With good fueling, conservative tuning on the FIC, and proper oil/heat monitoring, you’re setting yourself up for a reliable low-boost setup. Looking forward to seeing progress once you can get the car into the garage.
