My buddies tach kinda sketches out past 7k in his ls-v setup and bounces around. I've searched this and didn't really find anything useful that would help fix the problem.

Any ideas?

 

i got that same problem with my ls v that i got done to my car a couple weeks ago ever since we tuned it the guy that tuned it though said that its sumthing he did or programmed hopefully u find out cuz we wont be taken a look at it til next week

 

yeah, my buddy is running a phearable ecu basemap, i believe they use chrome. but not sure. I'm trying to convince my buddy to suck it up and pay 700 for a s300 with it preinstalled in a p72 but he doesn't believe it will make a difference. its so hard convincing newbies to spend money haha.

Any other suggestions?

 

oh and heres a vid i posted up on youtube so you can get a visual, might wanna turn the sound down, stupid phone sucks at recording sound.

thats exactly how mine is and we did use crome to tune it but it shouldnt matter cuz i know alot of people that use crome and there tach works fine and the same setup im doin its jus when they tuned it sumthin went wrong or isnt right but hopefully ill find out sumtime this week and tell u wat was wrong wit mine

If the tach is bouncing around, but the actual engine rpms aren't, it might be the ICM (aka ignitor). The ebay ignitor fixed my problem.
