they have a Fuel/Timing Calibrator specifically for the Lexus.

Hey Royce,

How are you? I am currently using one and few of my members also using them. I wrote two articles on this product:

How to install a Split Second FTC1
How to tune a Split Second FTC1

I hope the above links would help.

 

That piggyback is actually quite amongst some of the highly modified Solaras. I actually used one of their products to better my S/C Solara on closed loop. Their FTC is actually more precise and better piggyback compare to the A'pexi S-AFC

 

We had some sucess with the XFC from transmission controller. This unit only do fuel. Works great so far. Heard great things from Split second as well.
