Re: 2015 SI tune help

Rdx injectors will be installed also. I got the coolant bypass,throttle spacer,zdx throttle too. Rbc has been port matched to the zdx and polished. On my next oil change I have a magnetic drain plug ready.

Install should be end of week/start of next.

Re: 2015 SI tune help

So I've looked into it and found minimal info but it could be the fuel. I'm using 91 winter gas here, perhaps a higher octane could help or an engine cleaner? Even the sensor could be on the way out. We could test the continuity or a new one.

Re: 2015 SI tune help

Yeah that makes sense! I herd conflicting info when i looked it up. I know certain builds like it lower activation; I think I'll leave it alone. It definitely wouldn't be optimal cruising in vtech on the highway haha! I got bulk of my parts now and it will prob be a while before i get it machined ...

Re: 2015 SI tune help

Okay sounds good! Is there a reason vtech is at 4500 low and 5.5k Upper. Is one of those part throttle and other is WOT. Or is that the transition into vtech from low cams to high cams? I was thinking of moving those values closer together. I imagine it would mess up some timing and stuff to just ...

Re: 2015 SI tune help

yeah that first one there wasn't particularly impressive. I see it max out there in the pull at like 90% ish. Reputable RDX's definitely next for the rbc set up. It may be a while until i get everything bought and machined ready for installing. The temps are like -20C up here in Canada, thats why i ...

Re: 2015 SI tune help

The car feels smoother! First log was a bit short so here's 2. My RBC manifold just came in so I'll need some rdx injectors,3.5" intake and the zdx throttle body next. I might look into getting some fresh sparkplugs when I do my next maintenance, any recommendations considering my plans?

Re: 2015 SI tune help
