NOTE: The Installation will require a pigtail replacement to minitimer/Jetronic 

FLOW CHART: Each set is sold with a complete and unique flow-data chart indicating individual static flow rates at 3.0, 3.5, and 4.0 BAR. 

As well as 3.0 BAR dynamic pulse testing for idle (15% duty-cycle) and 50% duty-cycle. 

Along with a complete dead time off-set (latency) table. Flow matching was done with industry-standard equipment of the highest quality.

The tests were performed at varying temperatures to achieve realistic results. 

Linear tuning with excellent low-end, and idle rpm.

Fiveo is the only fuel injector seller that can claim this level of technology.


Ethanol based fuels tend to "dry" the fuel injector outlet orifices. 

Users/tuners should be made aware that this may cause a "sticking" problem in fuel injectors that sit idle for a prolonged period of time. 

It is suggested for applications running high ethanol content based fuels, to periodically incorporate into their fuel-system-maintenance a drop of light petroleum-based lubricant for each fuel injector. 

This is also considered to be good maintenance, but not essential, for stainless steel based (Black-Ops Series) fuel injectors.  

It should also be noted that for optimum performance the entire fuel system should be made up of ethanol approved materials including all fuel lines/fuel pump/fuel filter, etc.

**These injectors require MLK-Jetronic Adapters to run on your M156
