i'm wanting to add a dry shot to my setup. my idc is about 65% max. will i have enough injector for a 100 shot? before ya ask i want to use a dry shot cause i want to limit myself. i also like hsw's new interface that will let me fine tune a/f and timing through the maf. that away i can have a dead on n/a and nitrous tune. thanks

Your reason for wanting to run a dry shot seems pretty dumb to me. Why not just run a wet shot and have Justin set you up with a COS3 tune with a switch so you can switch between N/A and nitrous tunes.

 

cause i have hptuners and not efilive. plus the cost would be the same either way. this is the same method except my switch is a box.

 

Your sig says Blackbear tuned.... Old information?

 

he did a live tune on it 2 years ago. i have changed some things since then and have pm'd him a couple of times and he has never responded. he's a great tuner just busy.

 

Im not sure. You may be pushing it.. Maybe 75..

If it were me I would do a wet system in conjuction with the Lingerfelter controller. No need to worry about injector issues. Tuning the airfuel is as simple as changing out the fuel jet. Setting the timing is alot more reliable and it can pull up to 15 degrees and you can hook your tuning software to it to varify its working. No need to worry about connection issues using a piggy back controller.

Spend the money once and do it right the first time. Why limit your self right off the bat so that you have to spend more in the future? I just dont understand that thought process.

To answer your question I am right at 68% duty cycle with my marine injectors and im running a 100 shot very safely.

 

thanks. are you spraying before or after the maf? what do u do for tuning?

 

I am spraying before the maf. My truck is tuned locally with HPtuners but we make no changes at all to spray the 100 shot. I believe it has 29-30 degrees of timing in it and we have never seen knock under spray.

 

It MIGHT be ok,BUT start with a 50 shot to start with,then work your way up after you log the Inj.PW.
The HSW interface is a nice piece IMO.
