Hi i would like to know if i need to install the timing controlller box and ecu that they give with the ap1 vortech kit on my ap2.. !?

 

You don't need any of that if you have another means of tuning the car. The timing box I don't feel is ever needed personally. The ecu thing is what hides boost from the ecu. You can get a map sensor spacer which also hides the boost but those seem to cause hiccups in the driving.
Ap1 vortech kit doesn't come with the 5th injector that the ap2 kits came with. Pulley will provide less boost as well since the ap2 only revs to 8k instead of 9.

 

So i run it without any of that; without have having any problem?! I only install the sc itself?

 

And whAt is hiccup

 

No I said you needed a map sensor spacer at the very least. Best thing would be to get a stand alone ecu and have it tuned with some larger injectors.

Hiccup is when the car has a hesitation when driving or a stutter.

 

You should also definitely get a wideband gauge to monitor your afr. The vortech kits are notorious for running lean.

 

the ap2 04-05 timing box includes both map clamp and timing.

It will retard the timing as you go into boost and also hides boost from the map.

It's most definately needed if you plan on using the kit.

 

You don't need the timing part of it however so you can hide boost from the map sensor other ways such as a missing link spacer.

 

To keep it running safe, ideally you want to pull timing. You don't NEED to but it might save you from damaging your motor too. Unless you go full stand alone and have it tuned, I'd rather play it safe and getting the timing box

 

I found it to do much more bad than good. Comptech kits didn't come with anything for timing. The timing box causes all sorts of stuttering issues for me so I pulled it and never used it again. I am full stand alone now so don't use any of the stock kit electronics.
