Want to know if you can daily drive E30 mix with JB4 fuel wires and how this might affect longevity of the fuel system. Heard some people say to run 2-3 93 only tanks in between E mixes. Also heard from boosted in motion on youtube that JB4 fuel wires can’t be used on regular 93 gas due to lean AFR and prone knocking, this accurate? Want to run my fuel wires but don’t want to knock or ruin my fuel system.

JB4 w/ fuel wires unconnected

Yes...you can daily E30 as long as the logs look good. No need to switch fuels periodically. As for fuel wires on 93....those tend to run rich anyway. Best to upload a log for review.

would not recommend to daily your e30 map. fuel lines corrode over time for ethanol. only use it when u need to gap someone. if you want the consistent power do water meth injection BMS sells a kit that integrates into the jb4.

That is incorrect. Modern cars use fuel lines that are compatible with ethanol, they no longer use the old rubber lines of the past but instead use steel and nylon lines (ethanol compatible).
