Greddy type S Bov valve... properly installed? pics inside!

I compared the readings of my Sunpro gauge to an Auto Meter one, and they both read more or less the same. Good enough for me.

I figure there are good places and bad places to spend money, and a boost gauge is a bad place to spend a lot of money. It's just there so you can spot major problems quickly; if your tune relies on the accuracy of your eyes watching an analog boost gauge, you're doing it terribly, terribly wrong.

The only "premium" features that might be interesting are peak recall and warning, but those aren't necessary if you've got a proper tune, as a good tune will cut fuel if boost ever hits dangerous levels.

I'd rather have ignition cut then fuel cut i don't want a lean condition.

In theory, it would make sense...

Just with Haltech products, I would rather have the fuel cut.
The fuel cut is milder versus the ignition cut.
Remember, if you cut the fuel past the point of combustion, nothing happens in the engine.
With the ignition cut, you have intermittent spark events with the proper fuel, so you get nasty resonances - i.e. possible bearing damage - whenever this happens.

Rx7 has fuel cut???? hitting fuel cut is bad for rotary engines???????

On my LS vtec... i can hit fuel cut without any problem but in rotaries... im pretty scare to do that... Im correct... or...

From the way ted put it no. The stock ecu has fuel cut at 12psi, you should not go past 10 on a stock ecu. Honda motor and a Mazda rotory motor are worlds apart.

no never... i'm pretty scared about hitting fuel cut in this car.... and my car is totally stock.. and i dont wanna play with boost pressure... or something like that...

then... rx7's doens't have fuel cut at certain rpms? like any normal car?

I've always thought ignition cut was better, learn something everyday. I run a haltech and just updated to 1.08 i'll have to check what cut i have.
