Can the fuel wires have an effect on the car pulling timing? When having timing issues would it be better to run the JB4 with or without the fuel wire?

I use 94 Octane on Map1, new HKS plugs gapped at 024 (Veloster N)
and the car still pulls timing. (0.8-4.5)

I don't want to use an octane booster and I have a new intercooler coming, is there anything else I can do to try and eliminate the timing issue?

thanks

Fuel wires will help all around. Definitely worth getting.

I am already using the fuel wires just wondering what effect it might have on the timing. I have tried many different 91/93/94 octane fuels and it pulls timing no matter what I use on Map 1. I have an intercooler coming is there anything else I can do to try and eliminate the timing corrections other than Octane booster? the 93/94 octane should be more than enough without having to add booster.

Any recommendations?

Fuel wires won't typically have much affect but if you think you have an example where it did...please post a log and we'll take a look at it. That said...fuel type and octane will definitely have an effect.

I don't have an example where the fuel wires did I was just curious if they could have an effect on timing. Trying to figure out how I can get rid of the timing corrections by eliminating possibilities. Im using (Canadian) 94 octane and I have a new intercooler coming. Could spark plug gap or damaged plugs show up as timing being pulled in the logs?

thanks

Plugs could certainly have an effect but octane is typically the biggest contributor. if looking to get more aggressive, consider adding meth since you don't have E85 up north.

Did you ever get an answer to your question? I recently bought a VN as well and I'm seeing the exact same thing. I made a post in the sticky thread for Kia and Hyundai but no one had any comments (page 196 post 4894). I'm having the 0.8 to 4.5 timing pulls in my logs too. I've tried different plugs at different gaps. I've tried 93 octane and E30. I've tried map 0 (JB4 off) map 1 and map 2, as well as valet mode (half boost) no matter what, I'm seeing 0.8 to 4.5 deg timing pull. I'm beginning to think it's just how the VN reads. Every VN log I have seen so far has the same timing corrections also.
