Alright, some mods/boost questions

Recommended Posts

Just going through various instruction manuals and printouts that the previous owner of my car handed over to me when I bought it. Among them I've found instructions on: an HKS EVC system, an exhaust bypass valve mod and an HKS variable boost controller system (though I assume this was removed as I have a Blitz boost controller). Any ideas how to check if the first two are still present and active? Don't know if they are a good idea, especially the bypass valve mod.

 

Secondly, on the first boost setting, my Blitz dual SBC is still allowing my turbos to hit 0.7/1.1bar respectively, which is ludicrous for the first setting. Can I simply go into the gain mode and set the gain for the first setting to zero? The instructions say this will result in stock boost levels.

 

Thanks for any help

Doesn't the Blitz DSBC has 4 memory settings? Maybe the previous owner had setting 1 as his highest and the other 3 are set lower? Thats how I run mine......HTH

Went and had a play last night; turns out my first setting was set at 42% boost, way above stock but still the lowest setting. And here was me thinking that I'd been running it on low boost, and could explain the suprisingly high boost peaks to creep and cold weather. But no, the lowest setting was still high. Now, I've adjusted it so that the first setting is 0% boost, and I've turned the others down a little too.
