I got a couple questions on these too (not to hijack your thread).
Does the FC TB use a quality o-ring gasket like OEM?
Does it use the OEM TPS?
Will the throttle plate reach full open with less gas pedal travel than originally?
<font size="2" face="Verdana, Arial">The absolute value of the TPS is not really used for precise control. Each time you start the car the PCM looks at the TPS to determine what the closed value is. It uses the WOT (about 90%) value to determine when to go Open Loop. It uses the rate of throttle movement for enrichment and timing functions. It relies more on the MAF to calculate Load % than TPS reading. It will also "learn" new TPS settings as it would if aging components had caused a change.Originally posted by Welding Rod:
But what are the implications of the TPS sending signals that aren't exactly consistent with the OEM parameters - same air flow as measured by the MAF, but at a lesser throttle opening as measured by the TPS? Slightly more aggressive timing at any given flow value?
