Stock 2012 GT500(injector data)

[aaronson]

There has been some questions about injector data, and there are a lot of vehicles that use the LU47 injector. That being said different companies have different injector calibrations of the same part. Here is a stock 2012 gt500 that utilizes the LU 47 injectors. If you compare the values to the ford performance values you will find the high and low flow rate are quite different(along with other things), however the multipliers are very similar. Nonetheless, heres the tune, hope this helps anyone that may want a factory reference for lu47 injector data, and may not trust and want to use the ford performance.

I was under the impression all gt500's used a medium body injector like the g302. Ford performance list the g302 as the stock 47lber for the 2007-2010 variants, tasca parts shows it for 2007-2012. in 2013-2014 they received 52lb inj. but still medium body. the lu47 is a long body variant. Ive never taken an injector from a gt500 so maybe some of the info on the internet is wrong?

the roush 670 tune is the closest to normal looking lo/hi slopes ive found and the gen1 570tune works nearly the same but lo slope looks off. otherwise i have yet to find a true OE tune with the lu47. maybe they were built by bosch for something german to start? the audi guys swap various ones around in a similar manor to us too.

I ran an experiment and uploaded the values on my FBO 2014 gt with a dialed in MAF, It ended up being quite a bit off on fuel as to be expected. Im going to further experiment with as many different LU47 calibrations I can get my hands on and see if there's a justifiable difference in the tune changes. Such as cruise fueling, wot fueling, fuel economy, cold starts, hot starts, and injector duty cycle on 91 and e85.

let me know how things trend. happy to try more settings on my setup to help confirm what you find.
