So which injectors are you getting now

 

440 RC's

 

So the RC's and the UR's have different impedence. So are the RC's closer to stock?

 

From what I gather they (RC) are. No matter who makes injectors for our car, they should always be around 12 ohms. Myself and the person who I bought the UR injectors from are contacting UR to see if there is a mix up.

 

Talked to the guys at Ultimate Racing. They said their 440's for our car do run around 16 ohms. I know their our others running their injectors without problems. Called RC their injectors for our car runs 12.4 ohms. Could this impedance differance be the cause of my problems?


Thanks

 

tell me more about your problems, are you sure the car isnt running crappy due to temperature or weather changes?

 

No, temperatures have been pretty consistent. The first two tuning sessions the temps were in the mid 80's. The last tunning session it was a little bit cooler. Basically, you set up a map and do a dyno pull and the car runs great. 2 minutes later with the same map and the car runs rich and bogs. My tuner belives that since the impedance on the injectors is too high the stock computer and the part that controls the injector pulse can't read this high of an impedance and it's causing it to overheat and thus screwing everything up.

 

do you have any datalogs ?

 

No. Tuner might.

 

if you get get some datalogs of the general parameters, it would help.

or actually ill probably be in the south florida area this weekend tuning a few cars, if want me to take a look for you.

I dont think its your injectors. saturated injectors are usually 12-16 ohms.
