Yeah the spread sheet is only ball park, it doesn't account for engine volumetric efficiency, worked engines need the injector rate increased over the kinjflow calc to accommodate for the increase in VE and it's a double whammy if the BSFC is worse as most worked engines are.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.

Here is the latency data/ Voltage Offset (if you don't already have it).
The Part Number shown in the table cross references to Fl114962, it's the same injector.
You can change the Row Labels data in the XDF to suit the different Volts breakpoints, or just extrapolate the data from this table to the existing
TunerPro table.
These injectors are being used with an adapter and harness pigtail?
The data goes into Fuel: Injection Setup: Injector Bias vs Battery Voltage.

Nice work think I ended up using some offsets that delcowizzard put up for similar injectors that seem to be close but will def check. Been talking to him and he’s going to fit a surge tank and the pump as well

You can't change the row labels in the xdf to put the data in you would have to rewrite the ecu code in the tune. There's long body 60lb seimens deka 60lb and 80lb data n this forum in at the correct voltage breakpoints

Siemens 'long body' p/n FI114961 has different latency data vs 'short body' p/n FI114962.

Unless he has adaptors on the top they will be long body clones at a guess cause the 304 holden motor takes long injectors

Yes, that's why I asked DS about the body length, however I had no word back...

That would be one crazy mixed up injector. Long body with a short body p/n. Now that would scream fake ;)

Sorry mate I completely glazed over that question. The injectors are straight fit no pig tail or adaptors so good chance I’m fighting a loosing battle I’ll recheck the part no make sure it’s correct
