F-CON, is this a must have?
 

I saw this F-CON FS on ebay the other day.

Is this a must have for a TII w/ upgraded injectors. My 88 TII has a full 3" exhaust a Walbro 255 and is getting 720 cc injectors in the next 2 weeks.

So will I need a F-CON or some other computer to be able to run the 720's?

The seller makes it seem like you will have to do no tuning, just plug-n-play. Is this true or will I have to get it tuned specifically for my car on like a dyno or something.

You can't run it with 720 injectors, or any "upgrade" injectors for that matter.

I think you need the GCC to control bigger injectors on that. I cant remember who, but someone once said any authorized HKS dealer should beable to program it for larger injectors.

huh, ok, How about a s-afc. Would that let me control bigger injectors.

There's a guy on the fc3s_org YahooGroups list, and he posted his dyno sheet - "stock" F-CON with GCC, and he can't tune out the 720's in the secondaries. Getting chips for the F-CON is a royal pain in the ass - know anyone that has a custom one? I sure don't.

what does gcc stand for?

And whats the difference between the s-afc and the f-con. Just different people make them but they do the same thing?

And still

Henry from MazdaTrix said the F-Con can be used with bigger injectors fuel pump and so on. Call MazdaTrix or send them a Email. They seem to know what they are talking about a little bit better than some of these people.
I know this as I bought a Fcon form them and asked a whole list of questions and they awnswered them very well. They claim this is the best piggy back system available for the RX7s.
