Title: HKS EVC IV setup
Post by: leeroy_25 on March 27, 2010, 07:19:02 PM
Has anyone on here got one of these running a single turbo and external wastegate?
I was at the dyno today and Geff was trying to setup the controller and we just could not get a stable boost with it? The car has been running on wastegate pressure up till now and boosted perfectly. (46mm wastegate for info). As soon as we tried to use the boost controller to regulate boost and run a bit higher as soon as the boost kicks in the pressure is pulsing up and down like a yo yo.
Anyone got any ideas or do I just need to get a different Boost controler for my application?

Cheers
