Yes, you did.. You didn't answer to the person who question up but instead of keep questioning me back. No mention? Yes, I do use the SAFC 2 only. I know the stock ECU definitely cannot be tune la. Why i need to mention to you? Since i not asking you how to tune my car!
Anyway... since you state "You don't even know what is in your car, how are you going to tune it? (Turbo Change, Injectors?...up abit? up what?????)"... So now see how u gonna tune it.
My engine spec:
Block - 4AGE 16v - 140ps
Piston - 82.00 mm - lo com
Bearing - King Race Bearing
Rod - BC con rod
Crank - stock supercharge
Turbo - HKS Garrett 2530
Injector - 510 cc
Intercooler - Custom
Cam - TRD 272 in and ex - Lift 7.5 - Ex. 98° BTDC. In. 102° ATDC
Spring valve - HKS
Valve - 32mm intake and 27.5mm exhaust
Map sensor - supercharge
Fuel Pump - SARD 280 lph
My now SAFC setting is:
1000 rpm - -10%
1600 rpm - -8%
2200 rpm - -5%
2800 rpm - +2%
3400 rpm - +5%
4000 rpm - +10%
4600 rpm - +12%
5200 rpm - +12%
5800 rpm - +10%
6400 rpm - +11%
7000 rpm - +13%
7600 rpm - +14%
8200 rpm - +14%
Anyway I know Narrow band can be use too... But why i said need wide band is because you can tune for more power, closer to the edge, precisely monitoring Air/Fuel ratio Boost, EGT, RPM and throttle position datalogging
Bump:
Narrow band is Basic Air fuel meter lo... Got show rich and lean only...
Wide band is Advance Air Fuel meter with showing the exact digit ratio...
Autometer is a brand name...
