When some people have installed springs they have popped out the axle by accident damaging the seal into the transmission. This causes it to leak fluid and cause the transmission to go low on fluid causing lock outs and pop outs. Check for a leak at the axle to transmission connection on each side.
I believe you can adjust it on Hondata. If you decide to get unlocked and want a custom tune I would recommend @Jester04. He’s been awesome to me and my buddies who are also tuned by him!
This is very easy, I would recommend doing it yourself. Multiple videos on youtube you can watch. Here is one going the other way around but same process.
Full Race HPFP and Hondata 1530cc injectors is solid. I believe you will not exceed the OEM LPFP capability, but instead you will exceed the 92 fuel octane capability first. You will be able to run a decent amount of ethanol with it, but you'll eventually reach the OEM LPFP capability probably...
I was Phearable tuned but decided to go jester tuned when I got my downpipe. I have not once looked back. Car runs better and is smoother, I also like his linear power delivery a lot more, instead of all the torque slamming in your face down low it’s linear and helps the differential pull you...
You need a RMM to prevent it. I believe the PRL RMM is the most daily friendly, the other options from HaSport and 27won are more stiff but have even less wheel hop I believe. The RMM improved shifter feel and 1-2 shifts.
You don’t need an alignment unless you are having improper wear especially with a car so new. If you want to do an alignment because you do autox/track pull the camber pins on the top of the struts for additional negative camber.
