Injector compatibility

[Hesky]

Hi all, will these injectors work fine on our bosch motronic systems?

There fantastically priced, the impedance seems fine if I'm right in believing the S2 injectors are 15-17 ohms impedance, also the flow rate seem more than adequate for ~ 350bhp to (I think).
Would Mihnea or any other highly capable ECU hacker have no problem working with theses injectors when it comes time for a custom remap?

They don't flow that much and you should always keep an overhead on your injectors so you are not running too high a duty cycle. How much power are you ultimately targeting? 350 brake as you state above? Or do you want injectors that can cope with a bit more at a later date?

Any ECU Hacker can cope with different injectors, different fuel pressures etc.

Good for over 420 brake though.

Racetronix do carry some injectors that are compatable.

I am using these Siemens 599cc/hr (3172 part #), Doug, I think, is using the same set too.

We got them through Mihnea, and he had no problems using them.

You are right, they are great value .

Cheers,

Mark.

Hi Lee and Mark, my target is about 330-350bhp. I was thinking those Delphi injectors would cope just fine for that power range but as you suggested I would prefer not to run them flat out at there limit. I just couldn’t find any which have matching impedance to suit the motronic system.
Apparently those siemens are very good, seem to see everyone using them for aftermarket injectors. I just wasn’t sure they would be compatible with the bosch motronic ecu. Thanks Marc for verifying they work, 599cc/hr would be future proof for sure!

Its hard to get the RS2 injector cheap in the UK, well ive found anyway. but those siemens are almost half as much and seem to flow alot more.
