My 1jz swap is running on an aristo ecu and Harness. I've been living with weird driving characteristics. It's a dog under 3800-4000rpm. Once the tach swings by 4000, the car squats and takes off/spins the r888's. do you think the sub-tps you mentioned is my issue? I removed the wiring already... Should I spoof the inputs into the sub tps from the main tps?

Do not do what tweak tech says for the sub tps wiring. It is improper horrible advice, total waste of time. Sub tps unplugged will cause zero performance issues and early ecus won't even trigger a cel for it. If it does trigger a cel, a resistor wired in is the way to go. Another reason you're throwing away money buying a harness from him

As always, I appreciate your opinion. The OP is free to trick his ECU any way he likes. This is the way we do it with a 100% problem free results.

Its not an opinion, its a fact. You're doing it improperly. Just like you did my friend Ryan's harness, and lots of other people's harness, including this guy. Sorry cam, if you don't like it then learn how to do things properly. Feeding 5v sensors that probably never see the full 5v under working conditions the full 5v is not the right way to do things.
