So I have a B16 that i just had tuned and I have a weird question... is NepTune's shift indicator where the RPM's dip and bounce back?

 

The shift indicator would be where the checkengine light comes on at what ever rev limit you have it set for.

i believe your talking about launch control.

 

Your rpm's shouldn't dip and bounce back during acceleration.

Neptune has a shiftlight feature that lights up your check engine light as a shiftlight.

 

here is a short clip it does it at 9k everytime....
Ive tried 3 different dizzys, 1 cluster and 5 grounds on the engine.

comments welcome

That is not the shift indicator, as the check engine shiftlight is the only indicator we offer for that. If you have ignition cut and you're hitting the rev limit that could cause the tach needle to drop. If you're not hitting the rev limiter then it's something physical with your wiring, components, or cluster, as NepTune can't control your tach.

 

it looks like your rev limit is set to be an ignition cut and not a fuel cut.

if you use the ignition cut, the signal from the dizzy to the tack in interrupted and will make the needle go crazy.

try changing i to a fuel cut only and see if that fixes it

 

this might help a little bit
