Here's an update of mine. The setup:
-BP bored to 2.0L
-ported and polish head
-ported combustion head
-Supertech piston 9:1, dropped down to 8:7 (combustion head port)
-BKR7E plugs gapped 0.025"
-MSD HVC ignition
-Ramhorn turbo manifold
-GT3076R turbo @ 25 psi
-274 in/ex cams with 8deg overlap
-idle MAP is 34
And here's my target AFR
This is a tuned map, using G-Tech pro, LC1 wideband, autometer pyrometer and audible knock tool unit. I've found the max power is reached while the pyrometer shows 1450F, and as for cruise 36 degrees is the spot for fuel economy. 12.5:1 @ idle is set to drop down quickly the manifold turbo temperature and in my case I reach 750-800F after only 10-15sec of idle.
I'd like you to be careful especially with VJ23. Once you pass 6500rpm at high boost, it comes out of it's MAP and being inefficient, boosted air start to heat and combustion temp as well. You'll see 1600F @ 20 psi and you should drop the AFR down to 10.8:1-11:1 to protect the engine from melting a piston. Thrust me I've learned the bad way...When I bought my familia, I remember stock ECU was running the engine 10:1 @ 20 psi...there was a reason behind that, it was to lower the combustion temp. Too small advance will make the engine run very hot and too much advance will make the engine run cooler, as long as you enrich the fuel enough to protect the engine from knocking. Past 20psi, the last thing you should care is max engine output, but longevity.-1993 Familia GT-R, 3" stainless exaust, 0.100" oversize Supertech pistons, ported and polished head, "hemi" style combustion chamber, Supertech 1mm oversize valves, megasquirt, 880cc low-z, MSD HVC, custom SS ramhorn turbo manifold, GT3076R ar.63, 25psi, 3" SS custom exhaust. Soon to be MS3X, COP and 28psi!

Yeah it move +/- 1, everything's normal though. To get perfect idle PWM idle valve, injection time and ignition advance must be constant. If one of these value moves idle will.-1993 Familia GT-R, 3" stainless exaust, 0.100" oversize Supertech pistons, ported and polished head, "hemi" style combustion chamber, Supertech 1mm oversize valves, megasquirt, 880cc low-z, MSD HVC, custom SS ramhorn turbo manifold, GT3076R ar.63, 25psi, 3" SS custom exhaust.

NGK BCR8ES, the BKR7E plug is projected. You want the none projected version. Ive seen plug tips broken on the projected spark plugs.
Here's my advance table.

make sure to check and post your firmware version and msq along with it"Discontent is the first necessity of progress."

thats a composite log used for crank and cam signal testing.
1. what is it doing? oscillating at idle? then goto tunerstudio..datatlogging.. start logging
make sure to log a full start and warm up and the problem, press spacebar anytime it does something you want to look at later
BTW: that is an MS2 running 3.1.0 firmware, update it here http://www.msextra.com/doc/ms2extra/....html#download some time later after you get you maps steady.Last edited by MD323; 05-03-2012, 05:25 PM."Discontent is the first necessity of progress."
