Subject: Re: Super Ram on the way by istter1 on 2014/1/2 4:29:14 Read this not sure if this is relevant. Regarding the erratic cold start: It is difficult to get the right balance between start-up fuel enrichment vs coolant temp, open loop fuel vs coolant temp. spark advance and desired idle rpm vs coolant temp to get a stable idle right from start-up through warm-up. Expect lots of fine tuning in these areas to get it right. Regarding stalling: Stalling with the clutch disengaged while rolling is likely a mismatch between the min air and the warm IAC park position vs. coolant temp table. Not enough air! Either the min air is insufficient or the warm IAC park position vs coolant temp table is permitting the IAC to close too far. This needs to be tuned to match the car's demand for air at idle vs coolant temperature. A short term fix would be to increase the min air to something close or equal to your normal desired warm idle rpm, that way the IAC can't reduce the air to the point of stalling. It helps if you know the desired idle rpm to set the min air appropriately. If you increase the min air, be sure to set the tps back where it belongs, or the warm IAC park position table will hold the rpm up in a stationary idle. I see you have an 86 4+3. FYI: we recently hacked an 88 bin to work specifically for 86 4+3 cars. See this thread for more details: |
