i just installed 880cc injectors now my car skips like crazey. It does not have fuel on 2 and 4 cylinder. What all do i need to look for to fix problem.I used 10watt 10 ohm resistors from radio shack. also can running lean at idle blow your engine.

 

Running lean at idle won't blow up your motor.
What engine management do you have ? You can't simply install larger injectors & expect the car to run properly.

 

i am using crome 1.5 i have a tune that ran good on another car with the same setup. so then i also made my own map. I setup the battery offset for the 880cc and put i in 880cc in the fuel multiplier

 

only number 4 is not got any fuel any way to check the injector to see if it works.

 

I replied to your thread on PGMFI... get a resistor box dude. You shouldn't do that with RadioShack resistors. Make sure you did all your wiring right too.

And if you wonder if they're working or not, you should be able to put the blunt end of a screwdriver in your ear and touch the injector to hear if it's tapping.

 

can i use any honda resistor box or any specific box

 

i hope this works because i have no idea what else to do

 

Your best bet is to get a honda resistor box from a OBD0 car and wire it as per the website here.

this is what i did i used the top image I guess the radio shack resistors want work with 880cc

 

OK, I don't know anyone that has done the 10W 10Ohm resistors on the leads, so I really can't comment on it's effectiveness from experience. But on a practical basis, it seems like a bad idea because of the possibly poor quality of the resistors that are from RadioShack. Do what Honda did for years, obviously it worked so you can't argue with it.

That diagram for the wiring of the resistor box in your diagram isn't right... all of the wires should end up being connected.

If you can, get a Honda resistor box and wire it up like was done in the C Speed article. This is what I've seen in every low-impedance resistor setup in honda's and they've all worked. Do that, and get back to us.

 

i got a resistor box out of a accord but it is like a 1995 model i will go to the junk yard this week and get one from a crx or pre 92 civic.I am going to do if this dont fix it i am lost and the only guy that tunes cars in my area past away.

 

You'll get through it dude, you just have to do things slowly and logically. Worst comes to worst, take a **** load of pictures and videos so people can help you easier.

It may help if you take a little more time to make your posts a bit more understandable. (Sorry if English isn't your first langauge!)

 

english is my first language but typing is my worst means of communication.

Going to try to get time to fix it this afternoon.

 

wired in the resistor box runs like a champ no fu(k those radio shack resistors there ohms where off bad on was a 100ohm other was a 20ohm.i should post what i found to keep others from making this mistake.

 

I wouldn't. No offense but you're the first person I've heard of to do that, and the fact that the resistors were way off to begin with... I'd just leave it.

 

well every search i did about peak and hold done this

Yet both people just said get a resistor box right after that guy said it?
