can i install my rc 310cc injectors w/o a tune?

 

Do you have a stock ECU?

Actually, No matter if your ECU is stock or not. It's not a very good idea to just add fuel without a tune.

 

yeah if you do, your mpg will suffer, youl have too much fuel in the clylinders which cld lead to problems, but physically you can and nothing immediately is gna blow up

 

what if i add a adj fuel regulator?

 

you shld get a tune, is this for a stock motor?

 

An Adj. FPR will not do anything if you have no way to monitor what it is that you are adjusting. You would still require a type of tune in order to adj. fuel pressure.

 

It definitely isn't a good idea to add bigger injectors and not scale them inside the ecu.

You can think of it like this. With 310cc injectors on a stock ecu you are running ~23% more fuel every where if you do not scale the injectors.

Now an O2 sensor can pull fuel out for normal driving, etc. But at WOT the O2 sensor has absolutely no effect on the final fuel value. So you will essentially have 23% more fuel than stock at WOT which is NOT a good idea.

Best bet is to just get the ecu chipped or if it is already chipped then to get it setup for the correct injector size. Then you should be good to go atleast to get the car to a tuner.

 

i bought a hondata ecu thats tuned for 440cc injectors, can i use dat?

 

If you have hondata, then go into the parameters and just switch it from 440 to your 310's. If you run that tune with the 310's, then you will run super lean everywhere causing excessive heat buildup-- this is with the assumption that it actually will run.

Don't half-*** fuel management, you will regret it.

 

True statement.

 

ok guys, i was just makin sure, guess im gonna get it tuned, thanks guys
