Nice, there's 2 brands at 170lbs to compete and see who wins out for idle on gas and overall control.

What's missed is the actual usage and real world application.

 

[Mr.Spool]

Johnny here wants to run these on his grand national and decided to buy so he never needs to upgrade his injector now what?

What's cool about the injector dynamics company is they have a web page with data from different platforms and computer systems. Not as nice as if someone on here ran them and posted logs etc but a good starting point.

data like that is very helpful it was not something I had considered because I purchased a set of Bosch. come to find out it was a few days of looking and my vender that supplied then came up with the same data I found.

Some feedback to share with the FT170 and FT240s. Very user friendly but the user needs to understand how to tune an aftermarket ECU. I personally run the FT170s, they haven't missed a beat. The FT170s have a little better tunability idle manners than the FT240s in the Buicks from my experience.

Great, FT170s, can they idle on gas ok for us Flex cars?

Could you compare to the 160s in regard to that if you've ran those?

Do you know the specs like minimum pulse width for the 170s, maybe 1.3ms etc?
Thanks

Injector Dynamics info on lowest pulse width for their monster 1750cc/167lb on gas.


Key Low-Pulse-Width Performance for ID1750-XDS

Linear Operating Range: The ID1750-XDS maintains linearity within 2% down to approximately 2.0 ms effective pulse width. This means fuel delivery is proportional and predictable from 2.0 ms up to the upper nonlinear range (typically above 15-20 ms, depending on duty cycle and RPM).


Predictable Response Extension:
Due to Injector Dynamics' XDS (eXtended Dynamic Slope) technology, the injector provides usable, consistent response down to about 1.5 ms. Below this, flow variability increases, but it is still better balanced cylinder-to-cylinder than standard injectors of similar size. This improvement in low-end linearity supports better idle quality and drivability for high-horsepower builds (e.g., 150-190 hp per injector on E85 or gasoline).

Yes, the FT170s run well on E85. I have no experience with the 160s. I considered the Injector Dynamics but I also considered the price point of each and value added for my particular situation.

I believe Fuel Tech has that info available regarding minimum pulse width on their site. The 170s had better idle characteristics than the 240s, but you have to consider HP goals and what you plan to do with the vehicle. My car sees more street than race track. So I want the car to run well taking the kids to get ice cream

Thanks, seems like you're having good luck and enjoying the FT170s.

Ya I can't imagine 240s idling for us on gas.

FT170s are $1200 for 6
ID1750 are $1827 for 6

If the FT can go 2ms or 1.5ms without issue, then it seems like on the surface, big $ difference.

But of course there's more than price when it comes to quality, might be things FT are still learning that ID have down since they've been top notch for a while. ID has great design, research and testing so you gotta pay for the quality or it might be pumped up branding, not sure, still early for me in that big power world.

 

[Mr.Spool]

The reality of it is
you can only tune out so much at idle
It is possible to have too much injector or over injector
As the motor cannot physically use that fuel that early and or air is not moved soon enough

 

[Mr.Spool]

Remember its injector on time
