DIY - 1.8L 1ZZ-FE TB Connector Chip Swap

[MGargano]

I love the performance of the 1ZZ but the harsh oscillation is a killer. So I should reinstall the stock TB & chip for a week or so and then start over with the 1ZZ and chip swap?

That worked for me. You may be getting ocillation due to an air leak. Make sure you did the gasket maker correctly and really let it set up a long time (I let mine set up overnight). Check also the intake for leaks.

I pulled mine back off, waited a week, did the chip swap again, and re-installed and have had no probs since.

Thanks. I'll give that a try.

Did you get CEL and oscillation the first time you did the chip swap?
