So I installed RHD ITBs. Only 1 cylinder came tapped for vacuum. I used brass fittings to create a junction and connected both brakes and FPR/AFR to it. I noticed on RHD's website they now use a vacuum box with multiple fittings, I assume each cylinder is now tapped. Would this be affected my AFRs?
It idles around 1500rpm (no icv now) and sounds healthy, revs great, but my AFR gauge is reading 7.7-7.8. I grabbed the whole fuel VE table and dropped it 10 points and the idle went up and the exhaust note changed and it sounded leaner. But the AFR gauge did not move. I dropped it another 10 points, sounded really lean and immediately increased in 20 points. It settled back out again. The AFR gauge did not move during any of this. I shut the car off and after a bit the AFR gauge read 16, which for an supposedly empty exhaust pipe is impressive. Before the ITB install I'd idle 14.7-15 and WOT would be a solid 13.9.
I did not change my injectors. I had to remap the TPS to whatever came with it. The values were inverted but it mapped correctly and tracks accurately. Any ideas on where I went wrong?
Edit: Once I moved the car off my lawn the grass under my cat was brown and dead. Maybe 15 minutes of run time. I've never seen that before and it sits in that spot all the time.
2nd edit: I just remembered that I noticed Fuel Load was at 100% even at idle and it stayed at 100%. That shouldn't be happening, right?
