If you are running them with a 8V doing arround 140hp what is their duty cycle?

So in a PG/1H G60 motor they are working at their limit?

Re: G60 Injectors Duty Cycle Question (Black_cabbie)
In a stock PG they should be running about 80% iirc with the stock 3 bar fpr @ 145 WHP.
When most people (for years now) go to the Stage 3 or 4 PG, they upgrade the chip and go to a 3.5 bar fpr with the injectors going static around 5000 rpm. At that, they are goo to about 160-170whp or so (Estimate). Some claim more, but I find that hard to believe. I upgraded to Stage 4 this way and was starting to lean out a bit even when static around 5500rpm @ 15 PSI boost. Thus, I took them out a week later and went to a 42# set with a custom sns chip to match back at 3 bar. Now my WB LM1-LMA3 says they are at 79% duty at 6k rpm. I am probably running about 170 WHP right now (maybe a little less).
Here is my WB plot of those stock G60 injectors at 3.5 bar in my Stage 4 PG. the Green Line (Dwell) is the injector Duty Cycle. You can see they are set to go static via the chip around 5k.

Hope that helps.

I am curious to know how does the LM1-LMA3 know the duty cycle of the injectors.... Nice piece of hardware. Thinking of investing on one myself. For long term use.

I love wh0ring the pics and love the tool even more. I have many things to tune so I am putting it to good use.
The LMA 3 can log data from its 5 internal/external sensors (MAP, EGT, Dwell or Duty Cycle, RPM, Acceleration (MAp and Accel are not shown on the plot above) and A/F from the LM1) or external user installed sensors or any mix. One of the built in sensors measures Dwell. Just run a wire to the + Injector harness wire, another to ground for that channel and viola. It reads the Dwell Pulse. Great data to provide your chip programmer and invaluable if you have standalone (which I have been considering more and more on my Corrado).
I got mine from TWoody (wired4cars.com) here on the tex.

How much did you pay for it? And it comes with a Bosch WB send I think.
