I'm on SDS on the 2316 Raby kit engine that Drew Rickert built. Did a lot of mapping work on TPS only since the ITB's give a choppy MAP signal. I like the closed loop feature--makes the system seek 14.1:1 when cruising but will drop back to the tabled values when the TPS or RPM exceeds threshold values I set.
Something to note for those thinking about ITB's versus a single throttle body system is that for any cruising at 60mph or less the throttle is just barely cracked. These cars are so efficient, taking so little power to cruise. My readout for the throttle position sensor at idle is 4 on a scale of 50 at WOT. Any steady level road cruising below about 60mph the TPS is still sitting at 4 and will only move to 6 or occasionally 7 under mild acceleration. A single throttle body will provide more resolution to the throttle setting at the low power outputs in normal daily driving. Then again, when I romp on it & go WOT it's wild acceleration with a sound from the intake that you can't wipe off with a fistful of $100 bills! (IMG:style_emoticons/default/piratenanner.gif) |
