anyone with Blitz supercharger?

i believe one of the fixes for detonation is using fuel injectors from a 1zzfe engine. theyre relatively easy to come by used on places like newcelica.org. i think the problem is that there isnt enough fuel being sprayed by the 1nzfe injectors so you get detonation at wide open throttle (WOT)

OK. Sounds good and I certainly am willing to try it. I have since solved a good deal of the detonation issue, but still on rare occasion, I do still have a drop of it. I wonder, does the Yaris motor have a knock sensor that pulls out timing upon sensing detonation? Anyone know about this?

Please tell me how adversely the larger injectors that you suggest will negatively reduce fuel economy? Just wondering. I would expect some, but I'd still like to know more about this.

Thanks!
