I am in the process of hooking up my splice-in harness for my Gen7 DFI from Fast Track Performance.

I called Mac to ask him these questions, but while I am waiting for him to call me, I figured I would post here.

There is a Fuel Pump relay wier that is optional to hook up. It says you can leave the GEN7 to control the fuel pump, or leave it and have the stock PCM control it. What are the advantages or disadvantages of leaving the stock PCM control it? Gen7?

Is the HEGO sensor an option? I didn't receive an O2 sensor to replace mine, but, the kit instructions talk about replacing and then splicing into the harness. Of course, the kit instructions also talk about hooking up a cam signal (which is also an option)

Any ideas?

Thanks..

I don't know the advantages, but I know my setup is using the stock PCM to control the fuel pump.

One advantage might be that you KNOW your car started before you began with the wiring modification. So, if you don't change the way the fuel pump is controlled, that's one last thing you'll have to sort out later if you have problems.

 

let your stock PCM control fuel, and i am assuming you didnt get the wideband o2 option.. which I woudl highly reccomend doing..

 

Jordon,

Talked to Mac today. I am getting the innovative kit through him, he has a calibration that allows you to use GEN7 DFI with the Innovative Wideband. Very sweet. $360 instead of the $1000 DFI option.

He said the asme thing about letting the stock PCM control the fuel, better off that way I suppose.

Thanks for your help.

The nice thing about that setup your running is it uses a volkswagon 02 and they are like $50 to replace instead of the Hondas that come with the fast which are like $500. But how often do they go bad Im going on 4 years with mine, and its had plenty of lead

 

Sleeper are you using the accel with the LTCC?
