Summary of change:
http://vems.hu/www.vems.co.uk/VEMSConfigs/Ford/configRST1.0.73default.txt http://vems.hu/www.vems.co.uk/VEMSConfigs/Ford/tablesRST1.0.73Original.txt '''some notes from IRC''' * Can you think of any reason why a change from 1.0.53 to 1.0.73 would make idle and part throttle terrible? * No idea. Maybe I could explain if it were 1.0.73 to 1.0.53 * or, maybe the h[2] migration was forgotten and running on 2 cylinders ;-) make sure to change to h[2]=00 10 20 30 ... style instead of old 00 01 02 03 ... ** seems to be handled * looks like a 36-1 4cyl wasted spark * boostcontrol in use, with "simple-boost" (boost_conf bit1=1) setup ** That should not make any difference at idle and low load though ---- '''IAC''' * How do we stop the IACV from clicking if the engine is not running? ** the IACV must be at a position to be able to start the engine, so you cannot simply cut power ** my audi IAC valve stopped clicking when I set iac_speed=00, but my audi iac solenoid also needed a schottky flyback ** you think it might be flyback related then? ** some IAC valves like the 30V flyback (like the BMW dualsolenoid seems so), others like low-voltage flyback (=> try a diode, schottky or BY399 or 1n4007 if you only have that) '''IAC tuning''' * do you make good results with iac '''PID I=0 D=0 (proportional controller)''' ? ** not really - everything else was worse though. These guys are not too bothered about stable idle on a car with the cams its running. If you pay them to setup idle they'll do it. But no one does. Everyone wants a power curve and some throttle response :( * '''iac asymmetric behavior iac_conf bit6=1 got a bit more aggressive between 1.0.53 and 1.0.73'''. RPM < RPM_target, it was *2 earlier, now *4. With a reasonable iac tune that shouldn't make much difference (slightly better). With a mistuned iac, it might make it oscillating more. It seems like some '''iac tuning is needed''' in this case ;-) ---- '''Other''' * egt1_cal=64 ... something crazy must be going on (should be 0x49+-1, explain how you calibrate) ** EGT not used on this engine
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
