<![CDATA[EV1 vs EV6 Injectors for OBD1 m50]]>So I am thinking that at least one injector is not working quite right on my m50, they do have a ton of miles on them.  Rather than just replace them with the same but new or have these rebuilt/flow tested I am looking at ev6 injectors for the better flow atomization.  Has anyone found some that would be a direct flow match or close enough to the stock m50 injectors?  The closest I have found is the 19lb/hr ones used in some Fords, that would probably require a tune though.

The 42# Bosch "Green Giant" counterfeits run rampant on ebay

Carry on

0280155771  is a 17lb @3bar. Kindof a cream color, my calculation is 18.36 at 3.5 bar

Why would I use the 19lb?  I would rather not swap the FPR if I don't have to.

Going by gut feel I would expect the 0.86lb/hr difference to be no big deal

According to a calculator here http://www.fuelinjector.citymaker.com/Fuel_Injector_Flow_Rates.html the flow rate at 3.5 bar is 18.36lb/hr.  Do you think a .86 lb/hr difference is in the range that the ECU can adapt for?  I would think so but have no experience messing with injector sizes.  I would guess that it is going to be better than the injectors I have that are nearing 300k miles...

]]>https://wibimmers.com/post/80293https://wibimmers.com/post/80293Fri, 02 Jun 2017 19:21:40 GMT<![CDATA[Reply to EV1 vs EV6 Injectors for OBD1 m50 on Fri, 02 Jun 2017 19:03:44 GMT]]>The plastic body EV6 19# injectors are good stuff. Keep in mind that the 17# injector rating for your M50 injectors is at 3.5 BAR

If you drop down to a 3.0 bar FPR (or adjustable FPR) the 19# injectors will flow 17.5# which will work fine with your stock tune.

The MarkD chip for Motronic 1.3 is for 17# OR 19# injectors. I used them both. It was not a problem for the ECU to adapt to the larger injectors and whatever difference in injector characteristics (latency, voltage/flow change etc) was not an issue at all.
 

19# injectors would flow 20.5# at 3.5 bar and I think you would have some problems there.

if you want to leave the FPR stock, email Jay over at Sssquid tuning. He would probably be able to make a tune for you.
