You nailed it. Same issues we had on the Evo X throttle bodies. Those issues have been resolved, we just have had the FA20 TB's on the back burner. Hopefully we can get this started back up.

Yeah...damn drive by wire.

Yeah, I know. Don't worry, we will make it work

woo! keep at it. Someday, someone will solve the question to making N/A power on these cars... Thanks for working at it! Always cool to see a company doing some real development, even if it ends up doing nothing, well, one more variable eliminated, we would know that it does in fact, not help (on setups x, y, z)

interested as well

We keep getting set back with the Evo X DBW throttle bodies. We need to master those before we finish the FRS/BRZ ones. On the plus side, the same issues we had in testing with the FA20 throttle bodies, is also happening with the Evo X ones. I think if we can figure it out, we can apply that to the FA20 TB's as well. I will keep everyone posted.

Going into one year. Any updates?

MAPerformance · 12-01-2014, 11:14 AM

No sir sorry to say. This is still on the back burner of projects we need to finish. I promise I will update this thread with good or bad news when we are ready.

Just an idea. With the same % opening to achieve 650rpm idle with 65mm throttle plate you'll have a larger air flow with the 68mm throttle plate, which results in higher idle rpm. Basically you'd need to add some form of bias. Either mechanically or electronically.

@MAPerformance is there any news on this item

icauntdrive · 06-14-2015, 11:21 PM

Well, im running 68MM tb with FI setup and have no luck with the cel. First it was the TB sensor code then its the P0068 MAF/MAP code that was related to Throttle position correlation. Im thinking of going back to stock TB. Plus The larger TB make the car idle high up to 3000rpm some random times when you clutch in and put it in gear. I dont know if its just me or is anyone else experiencing the same?

Did you adjust the throttle angle g/s table? You may also need to adjust the cylinder fill one as well. I at one point had adjusted my throttle angle compensation as my turbo pushes air into the engine at idle higher than the ecu expects and the car was drifting upwards and would take a moment for the ecu to shut the throttle.
