I actually have it graphed, but to your point, I don't really know what it was supposed to look like. I saw it go lean and thought "okay, I can add a bit more fuel" but that obviously didn't do anything good. I should have thought to try less fuel, even if that didn't seem right.

Had a moment this morning to test this and it definitely helped. Will have to dial it in, of course, but I see light at the end of the tunnel now. I feel silly not to have seen it myself. Thank you!

Thanks. I will give that a try and report back.

Hello, I've got an SC400 w/ 1uz VVTI motor. Previously it had a stock motor and the tune was great. I had a new motor build, with big cam and head work to match, etc, etc. I basically scaled the old tune up a bit and it seems to work okay. But at low RPM, when I floor it, or tip in significantly, I get a lot of popping and banging, then it starts to go. It looks like it goes lean on me: I have tried playing with various accel enrichment settings and cannot get it to go away. Any thoughts or help would be appreciated. Thank you!

I tried setting them to .5, thinking that would give me room, but then the "meter" capped out at 500. They're back to 1.0 now.

I have a 1999 SC400 w/ 1UZ VVTI motor. Recently installed a Link G4+ Xtreme ECU in it. No real issues there, car runs great so far. I have been struggling with getting the knock sensor set up, though. I'm getting data, but it is too loud. Even with gain set to "1", normal acceleration is spiking over the "1000" threshold. Before I start looking at alternative knock sensors and other "hardware" solutions, is there anything I might try in software? Right now it is setup to look at 6Hz signals; I was thinking about trying 5Hz or 7Hz just to see what the data looks like. Sorry if this is a stupid question.
