I was wondering, I recently bought 2 injectors from Fritz, they were origionally 550's but got worked on by RC engineering and are 750s now.

I figured hey, I have a dp and a more free flowing exaust now so I might as well just run a little rich to be safe.

So my question is, can my car handle 750 cc primary injectors on a stock ECU?

If not... well, does anyone have a good working 550 cc injector for sale?? I need it by Monday !

 

Nope, the stock ECU doesn't know that the injectors are enlarged so it won't be able to supply the correct fuel for your A/F ratio.

 

son of a...


so I couldnt run them and just let my car run rich???

blah..

what would happen if I tried running them w/ the stock ECU???

 

Damn, man. Bad stuff--the stock ecu definitely doesn't like running diff size injectors. Call Steve, Chris or Ihor at Gotham. The number is on the website. We should have a used set laying around. Hell, I have mine floating around, but who knows where in Steve's house they are....

 

haha, Steve... is that the guy that flew off the track at the Dallas Motor Speed Way not too long ago??? That guy was great.


Yea I'll make sure to give him a call, thanks.

IMO, unless you have a need for larger primary injectors, just get a set of standard 550's. It will save you hassles in the long run.

When you do have a need for larger primaries, do it right and get a programmable ECU like the PFC, or Haltech, etc..

 

Hmmm, doubt it. Steve's a pretty dang good driver. Are you referring to the dipshit that flew off of Motorsport Ranch? Because if so, that dipshit was me

 

aha, yea... that was the day the chick driving the supra dumped her oil pan while on the track ending the even short correct??

 

Roger that. That day blew ***. My worst day at MSR by far. I need to find me some more S02s; I didn't like the damn Yoko AVS Int at all. Plus, hardly any track time. Ah well. I'm glad I was able to amuse you

 

Ok, so I need to hear this story lol

What did you do? Are we talking a drag strip or a road course???
