jimjam92 Posted December 28, 2017 Share Posted December 28, 2017 (edited) Hi Guys, couple of questions; I've got all of my BPU stuff sitting at home waiting to go on (whifbitz 1st decat and restrictor ring, walbro 255 fuel pump, HKS FCD and new NGK iridium plugs). My car already has a Blitz Nurspec exhaust and 2nd decat. My first question is - which boost controller would people recommend? I'm looking at a Greddy Profec B II (old style) or a HKS EVC-5, both are also 2nd hand but look to be in good condition. Does anyone have experience of either and what are your recommendations in terms of ease of use, accuracy, performance etc. Secondly, for a BPU car is there any benefit to running a piggy back ECU? Having heard of members cars either running leaner or richer after going BPU have been looking at these and would most likely go for a Greddy Emanage Blue. Is it worth having that little bit of extra control over fueling rather than letting god sort it out for me, or is this just overkill?? Car is a 96 Auto J-spec TT. Thanks Edited December 28, 2017 by jimjam92 (see edit history) Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted December 28, 2017 Share Posted December 28, 2017 Dont know about the HKS, i have used Blitz stuff, some cars are perfectly happy at BPU with std ECU others not, give it a try and see how it works out, then decide if it needs exstra tweeking, but personally i wouldent bother with the blue as its not all that, EMU will give much more control if needed.

samdale Posted December 28, 2017 Share Posted December 28, 2017 Having heard of members cars either running leaner or richer after going BPU Have you got, or are you going to fit, an AFR gauge? That's my plan to keep an eye on things. Link to comment Share on other sites More sharing options...

Most likely not, as trying to keep my interior as stock looking as possible. Unless I can install one out of sight that is? Link to comment Share on other sites More sharing options...

samdale Posted December 28, 2017 Share Posted December 28, 2017 (edited) if its out of sight it kinda defeats the purpose of it though...... I think once all parts are installed and running, all boost controller settings nailed down, then I'll start to hide things away. I'm looking around the cabin for good places to do this. Centre console possibly. Maybe even mount a couple of gauges and the boost controller into some sort of box that can be brought out for tuning/setup and left hidden away. Plenty of room behind that lower panel beneath the steering column. Or the same location on the passenger side. I've bought an analogue AEM AFR gauge purely because of its subtle looks so will see how it looks and decide then. Edit: building it all into the glove box is another option Edited December 28, 2017 by samdale (see edit history) Link to comment Share on other sites More sharing options...
