So, i got a haltech ecu, and im looking for some help, i got a problem where i dont get any fuel to the engine at low TPS, if i go from 2% (idel), and go to 6%, the engine will stall due to no fuel.
if i have a higher rpm and go to 10-20% it will not stall, but the it will drop from 2k till 4-500rpm before it catches up.
i have tryed change everything... feels like nothing helps, or is it something i missd. i have changed the TPS dampening and filters, all the way from 0 to 4000%
transients settings from -100 to 300%, the behavior is the same. i cant make it keep that "spike" for longer...
i have removed the superchager to see if it whas a build up from it in the intake, didnt change the behavior.
Is your fuel table tuned? I see your short term fuel trims are 4-4.5% with the engine warm before your throttle blip. And they are part of the reason for your lambda swings. Perhaps you can create a log with the throttle slowly changing to rev up to 2500-3000 rpm and return to idle to make sure your fuel table is tuned in those areas.
Also, your transient throttle ignition correction might be hurting you. Removing 3 deg of timing immediately, then when the engine slows (and the timing appears to be lower), it's hard for the engine to accelerate. So you might want to visit the ignition table at low loads.
Check for interactions with your idle control system. Sometimes it will still be active, and trying to slow the engine instead of leading it accelerate.
