Data Logging the car reveals terror
#21
I remember reading something about this. For example, tuning 1100cc injectors down 50% will not make them act like 550s.
If I cared enough about it I'd go search on dsmtalk but I'll stick with some 650cc disc/ball style injectors for $250 that PWR VTEC is gonna tell us how to get.

ah yes i agree you can tune down 50%, the biggest a dsm can handle with a afc are 660's, with rx7's this may be differnent. A well known dsm specailty site has confirmed this to be true. I think it was road race engineering. Anything larger than 660s cant be tuned down enough with our cars.

Agreed, and i have no idea why 660s are as large as dsms can go with a afc, wouldnt make since 440s ;660 areent 50% larger insize,should be able to run 880's; maybe they do deliver 50% more fuel though. I really dont feel like looking right now for the anwer maybe later

I'm telling you, the answer is on dsmtalk.com
When I said they won't act like 550s, that's exactly what I meant. I didn't say they won't act exactly like them, I said they won't act like them.
Please refrain from stating the obvious when discussing things with me. It is insulting and a waste of both our times.

I think the main problem is that our cars are tuned rich as fuck from the factory as it is. I pulled 13 percent from mine right now and have not upgraded the injectors yet. Then if you add a set of 750 or larger injectors on there it just won't work out.
Also the injectors don't quite work right under a certain duty cycle. (I would think) There's gotta be a minimun reccomended duty cycle as well as a Maximum. Lets just speak in theory right now numbers are just guidelines. If you are opening a 1000 cc injector for 1 second and spraying the same amount of fuel that a 550 sprays in 3 don't you think the air fuel ratio will be wack? I would think it wouldn't mix right.
Alot of guys I've seen making high horsepower (normally over 500) on a daily driven dsm have been using an 8 injector setup. I'm pretty sure they do this for a reason.
