shift light?

take it to your tuner and tell him about it.

Use the diagnostic plug connector to check for stored codes. Very strange that it worked fine on the dyno and not after. They must have unhooked a sensor and that should throw a check engine light. Does the light come on with the rest of the lights when the key is on engine off?

- Mon Jun 18, 2012 5:07 am #308580 First off do you have a jdm cluster?

I had the same problem with mine (jdm cluster). I had a stock motor B16A and it only redlined at 7800. I held the gas in to double check and it just bounced of the rev limiter. When everyone know a B16 motor redlines at 8200.

For me the problem was with the cluster. I just adjusted the potentiometers in the back and got it where the redline need to be

The check in engine light coming on at that cluster is your shift light. You can have that taken off by the person who tuned your car if you want. Its an option in the tuning software.

I don't know if the stock has the potentiometer but you can take out the rpm gauge to check.

- Tue Jun 19, 2012 12:21 am #308663 The cluster has nothing to do with all of that you need to take it back to the shop who dyno'd it and have them check if it went into limp mode from a log issue.

What engine management are you using?
