$58 boost control

[sae]

How flat of boost have some of you been able to get with $58 on a stock turbo and stock wg setup?

I'm also curious what RPM you hit your target boost.

This is just to hold me over until spring, I can't spend any more money on car crap until next year, so no 3bar for a while, otherwise I'd be running code 59.

Depends on the exhaust. With a fairly restrictive exhaust, you can get it as flat as any aftermarket controller. You may want to play around in F70 & F71, but the factory hardware is more than adequate.

Re: $58 boost control

Is it possible to hit, say 14.5 psi and hold that steadily throughout the rpm range? Right now I hit 14.4, it holds and drops to 13, goes back up to 14.5, drops again and then shift comes and it drops more. I'm still working on it but if I get it to stay within 1 psi would it be best to call it good?

Edit: This is on stock everything

Re: $58 boost control

Most would probably call that good, but you can achieve the stability you desire. Dig wrote some extra wg control years ago in the form of F70_mph and F71_mph that allows you to anticipate boost drops/spikes with the wg control. What bin are you using and what tuning software?

Re: $58 boost control

I'm on stock bin, all I've really done is turn off egr and change fueling a bit so far. Do you have a stock bin with those tables added? I'm using TP5. Also, you have a pm

Re: $58 boost control

I found an xdf with the tables for mph wastegate duty cycles, but they say that mods to the bin are necessary. It looks like all 3 tables have the same address too, is that right? How do I go about changing the bin, or does someone have one that's already modified?
