EFIDynoTuning Forum

Injectors in pre-tune write-up suggested are Siemens Deka 80lbs/hr (Siemens part FI114700 or A2C32624700) which are no longer available anywhere. They were wonderful injectors with a 9-pinhole nozzle, 2.5ms PW, 20ms period, 18.6mg/pulse, and matching OEM short length, etc.
What alternatives are suggested now that those are gone? Vendors gave me Ford Perf-Romance parts, but they look too long to fit.. anyone else?
I'm getting ready to start tuning this rebuilt Windsor 302, still going through the pre-tune information, and seem to be stuck on fuel injectors choice. I think 302 windsors are EV1 connectors, short style
Anyone else, thoughts?

Unfortunately there are no alternatives.

If you can get by with the ford racing LU47s those are fine.

If you need something larger then the ID1300's should be fine.

Siemens doesn't care about the aftermarket so even though they claim to have a batch ready Im not counting on them ever getting released.

Shame because that injector dominated the market over 15 years since its OEM release with the 2008 cobra jet.

Very unlikely ford makes any newer injectors comparable since all of their engines are direct injected so theres no need.

DW has a 1000cc injector they claim is flow matched that you can order for ~$650 through PAS. Thats a route many have recently taken as well.

Thanks for reply.
Since we can't push more than appx 550hp out of the 302w, I think DW 550cc (54lbs) will suffice. Part number 18U-01-0050-8 . They are about $450.
Found a datasheet for these here https://static.summitracing.com/global/ ... 20ford.pdf
Looks like this:
LO-SLP (lb/s) 0.013852
HI-SLP (lb/s) 0.014714
ST-FLO (lb/hr) 54.4
MIN-PW (ms) 0.73
FUEL-BKPT (lb) 0.0000196575

Is that enough data to work with a QH2 EEC-IV tune?

54s will only support 440rwhp on e85.

but yeah you can make anything work
give them a go and let us know
