Thanks Smile.

It's not a scanner, that's VemsTune, a special software for calibrating VEMS stand alone.

Throttle response video:

Speaking of idle with big 910 cc/min injectors..

Looks good. I got mine smog tested today, 1000cc and running nicely at lambda 1.00 and 700 rpms... Razz

Thanks Smile. Yeah, it's not a big deal to get even lower stable idle rpms. Just wanted to bust a well known myth here that everything above 600 cc/min and idle will suffer Very Happy.

Still in "safe" mode (boost below 2 bar) Very Happy.

..and still GT3071..? Any decisions for new turbo set up? Something big and ugly.. Twisted Evil Try some Holset or Schwitzer.. Razz Those turbos are really "bang for the buck".. Very Happy

Yeah, still "old" nice GT3071r Smile. Still not decided, I like the response of 3071, with it the engine have boost very soon (0,1 bar at 1800 rpm) and wide power range (from 3500 to 7500 rpm), which is great for a DD car. Going with much bigger turbo I'll loose DD ability I'm afraid.

Pulls really nicely, how much was max boost in that video? Do you still limit the boost or let it rise to max boost when its possible? Razz
