Re: (hondachris1994)
How vague.
What is "too much." And in which direction?
Advancing timing is fine for cars with n/a setups that are less likely to knock/detonate.
There's no automatic answer. It varies per application/motor/setup/fuel
With boosted setups you usually retard timing to prevent knock/ping.

Read it.
What are you doing going to a tuner or modifying your car when you don't know what changing the timing does?
And you don't "put on" timing, you either advance it, or retard it. Your engine ALWAYS has timing. It's not something you add.

Re: (hondachris1994)
I'm really a bit confused about what your situation is here.
The basic answer is, yes, advancing the timing too much will result in detonation.
When you say your tuner had to "put timing in the motor", what exactly do you mean? How is the car tuned, and are you referring to him advancing the base timing at the distributor or playing with the timing maps in the ECU? It sounds as if you're talking about the base timing at the distributor. If so, what setting are you using?

How would you have altered the ECU's timing maps by changing the timing belt?

Re: (hondachris1994)
Well either way, the only effect it would have had is on base timing (not the timing maps themselves), and that should not have changed either unless your timing belt was not installed correctly to begin with.

I put the b16 stock chip back in for a while, but yesterday I put the other chip back in and just retard the timing all the way back on the dizzy, and I have no detonation and the car runs like it did when it was first tuned

You sound like your swapping sunglasses.
