electronic boost controllers.....

[greathuskie]

im talking about the ones that sit inside your car that have the digital display
ive heard they are not very accurate and a MBC is better, is this true?

Some are hareder to program than others*cough* AVC-R*cough* but the normally control boost spike better than an MBC. I have a MBC and will be switching to an EBC for control from the cockpit.

boost spike?

and also can someone explain the whole bar thing? (like a car runs 2.3 bar)

 

[L2RTSiAWD]

1 bar is 14.7 psi.

boost spike is when you have the bc set to 15 psi and it spikes to 19 then settles back down to 15 thats boost spike

ohhh

hehe, 14.7 is a popular number in car terms i guess
stoich A/F ratio...1 bar....

I love my AVCR, but I also have a MBC on my other car. It spikes to 16PSI then settles down to 14#'s. My AVCR controls 30#'s, and its rock solid. I programmed it, took me about 1 month to get it dialed in perfectly, meaning no surge, no spikes, and no spinning all four up to third anymore. Great EBC if you ask me.

Get a Profec B or an HKS EVC EZ.

It hold boost to 30+lb fine.

I've ran over 1000HP on an HKS EVC EZ fine with no spike at all. But I had a huge wastegate on my car.

...of course bar is a measure of pressure; while a/f ratio, is not.
