Default Which 80s siemens or delphis..

Looking at 80s as think going to sell off new 120s and low impedence setup. I have problem with my car so can't run 120s getting cam sensor code and it goes to batch fire and 120s won't idle no matter what we do. When the cam sensor code goes away which is getting to be more infrequently the 120s work great but dont' want to be flatbedded .
I know the 60 siemens I had worked good even with the cam sensor code car still ran. 80s might be ok too not sure.

But anyway what 80s are you running siemens or delphis are you on stock ecu and using hptuners like me. Would also appreciate what other things you had to do to get them to idle besides just inputing the correct ifr. I did zip with the 60s just ifr no changed to anything else and they ran fine but that was on maf and 1 bar not 3 bar like am on currently.

the 80 Siemens tune like the 60's.. they are high impedance and will work with the stock ecu.. the delphi are low impedance but are 75 or 85 no 80..

they are made by Standard Motor Products. here is from the web site.. these are claimed to be the same as the delphi, but the delphi is a ball and seat not disc.. I'm confused. They also state they are 79 but in the flow data they flow 76.
here's the info from theur website.
Racetronix Part # INJL79FM
Manu Part # 01D129x
This new injector uses the same technology as the Delphi Disc injectors. This injector exhibits excellent street manners given its size.
All tests run with n-Heptane (0.6855g/mL) @ 20oC (+/-1oC), 3.0 Bar (+/-0.01 Bar) (43.5PSI) , 14VDC (+/-0.05VDC), saturated driver (70V zener cutoff). Engineering data specifies a flow ratio of apx. 1.035:1 when converting to gas.

Specfications:
Static Flow Rate: 76.65 lb/hr = 9.67 g/s = 846 cc/min (+/-4%)
Dynamic Flow @ 2.5ms PW @ 100Hz: 16.88 mg/pulse +/-10% @ 2.5ms PW @ 100Hz
Coil Resistance: 12.2 Ohms (+/-0.35 Ohms) (This high-impedance injector will work with all factory ECM/PCM injector drivers)
Spray pattern: 3-Prong Cone
Body: Top-Feed EV1 Style Body
Factory fitted with Viton upper and lower o-rings
Grease supplied to lubricate o-rings prior to installation.

We sell these also, IMO the seimens is a better injector.. Plus we have them on sale for $399. a set

They are 76 with heptane and you mulitply to get gas rating..around 79.33 at 43.5psi.
Obivously flow like 91 at 58psi.
The anticlogging sounds interesting to me one reason got similar made 120s. And they do seem pretty quiet and even look nice in their silver billet ,talking the 120s and they did idle nice when my cam sensor is working.

many people like them.. I just wanted to clarify that they are not Delphi.. We sell them for $54.00 each plus 11.60 flat shipping after the 5.00 off for the forum members. Just remember the Siemens is a true 80 flowing 875CC on heptaine so they are a little bigger,
