I have the pro racer set up on my pt88 03 cobra. I have ford aqua or teal top 160lb injectors with a versafueler. I'm not sure how to start changing the tune because I can't find any information on the injectors. The tune I currently have is set up for 60lb injectors. Any advice is greatly appreciated!

 

First off the pcm has a different driver for the injectors (impedance), from what i can remember, you will need a versafueler for the low impedance injectors and then scale the injectors accordingly, the high/low slop is available through ford racing im sure or can be found online

 

set MPW to zero and put in Bosch injector data (which sucks),

I'm sub'ing b/c I also have a Versafueler and white top 160's. I have zero issues with this set up, runs like my FRPP 80's ...BUT at part throttle (enough to maintain speed) I get a slight studder or hiccup. Not sure what were missing.

 

i've tuned a bunch of them, its simple enough, just scale everything by *.3 and adjust accordingly

 

So far I haven't found much on these injectors. I'm swapping them in within the next couple of weeks. The tune was pretty good with the 60's in there, but now I'm stuck trying to figure out how to get to a decent starting point with these. Any body have the bosch injector values mentioned above? Thanks!

 

Fuel injector values before scaling:
Low slope 0.044912
High slope 0.035086
Breakpoint 0.0002751948
Min. pulse width .00642

 

are you serious only 126lb? that sucks

in any case in response to the pm i received


by scaling i mean to multiply the slopes breakpoint maf curve engine size and idle airflow functions by multiplying by .3

thats only good for approx 1800hp though which will work out considering your injectors are only good for 1800 or only 1450hp if they really do only flow 126lbs/hr

 

Not sure what you mean by 126lb maybe my pm had a typo. They are 160s. Thanks for the help guys!

 

here is the only thing I find for ford injectors that big, would figure these are the 160s once at 43# of fuel pressure
