One more 16g thread - few questions
My car has never driven so well since before the Turbo...I can not put it into words. But...I will try.
I never noticed how bad it had gotten, but going from a stop to 1st was very rocky. AFR would swing rich or lean, and make rattle noises as the rpms dipped or jumped around. When I switched gears it would jerk pretty bad, didn't feel smooth at all. When WOT, I saw a fair amount of shift knock....all of that seems gone now. Literally, it shifts like butter, idles like a champ, just rocks my world!
Here's what I did: Put evo settings back in the idle section, and flashed the ROM. Then, I set the BISS calibration mode in evoscan, and the car died. I turned the BISS screw out 1 full turn, then started the car again, and set BISS mode....died again. 1 more full turn out, and the car didn't die this time, but sat at 300 rpm. I jumped out, went to the engine, and turned it 4 more full turns and listened to the idle climb steadily to about 950 or so. I tightened it back down 1.5 turns, and it sat right at what I thought was 750 rpm.
Turned off BISS mode and went for a quick drive, literally drove like a champ right away. Shifts were the first thing I noticed just working so well. Next I noticed the idle was pretty high. My ISCV trim was at 9 before I started this adjustment, it fell to about 6 within a couple minutes, but still idled high. After about 4-5 minutes of driving and stopping at stop signs and what not, it had dropped to about ...-1 or so, and was hitting target idle exactly. It was the evo setting, so I turned back to just my target idle settings, but left stepper and ISCV and all that. It loved that as well, idled perfectly at 702 or whatever, turned the A/C on, it flip flopped between them roughly at first, until the ISCV trim for A/C on got lined out, and then it was just perfect.
I'm sorry for droning on there so bad, but this was so freakin huge as far as the cars drivability goes. I wanted to just stay out all night driving...but I had to stop, dinner and all that jazz.
Also, bought a new boost gauge (AEM analog) since my glowshift is a real piece of junk. There is something electrically wrong with the sender, and rather than replace it...I'm just stepping up to a good quality one.

PS any update on tomorrow (cant find my cell)
Don't necessarily have to change anything, but just set it in neutral, all accessories off, and activate the mode when sitting still....see what it does, whether the car dies or what...I am seriously curious if everyone elses is way out of whack.
Well I gave this a shot. I activated the mode before changing anything and idle did not change all I got was a CEL lol. As soon as I deactivate then my cel goes off. I flashed in stock evo isc tables and stock evo target idle values and car would start and abruply die. I gave the biss two turns out and tried again. It started and idled barely. Gave it another turn and seemed better, activated the sas mode and idle didnt change. I was sitting at about 10 steps, I gave it another 1/2 turn and brought me to about 7 steps. Did one more full turn and brought me to right about 0 steps. Idle seemed a little high still so put lancer values in the bottom 3 cells of the target idle.
I think I need to adjust some more, at this point Im not sure if it has helped or not. Still getting dips one after another after another :-/. Idle seems to be at like 1100 and dips although more rapid and shallow. Before it would dip randomly and drop to like 400 rpms. Now its pretty constant and dips to maybe 700? then goes back up to 1000-1100. Bout to take a trip to english over this crap lol.
Should I drop the biss back down a turn or so to give the steps some room? Not sure what to do honestly at this point all just confuses me esp not knowing for sure if these table are even labelled correctly.

Yes, cel for SAS mode on, scared me at first too.
As far as adjustment, what you want to do is get it to, when SAS mode is on, is to idle at 700rpm +/- 50 either way. Then, after you change that, the idle will be off when you turn SAS mode back off, because the car has "ISCV Trims". Put these items in EvoScan and you will see what I am talking about.
