Idle issues after installing 550cc injectors MS3x
4 Attachment(s)
See attached tune and data log
The car starts and idles but idles rich and likes to drop way below 850rpm. I have tried to figure out the injector dead time... but I bought some cheap ones off ebay that didn't give any of that info. They are rebuild denso 550cc's.. but besides that... I don't know much more. I have also tried playing with the accel pump settings... |
Are they high or low impedance?

High impedance

RX-7 or RC injectors?
|
were these injectors cleaned? old rx7 injectors? going by your fuel map, it looks like you're barely injecting fuel at idle.
yeah. 1.6ms at idle is probably as fast as these can cycle, and youre still at 11.0:1. either the AFR settings are bad, or one or two or three or four of these are just dumping in fuel at idle. |
