XFI wired can I turn key to check for fuel leaks?

[Heath]

Just got XFI wired . Can I turn key to check for leaks? Do I need to do something to the computer first?

Power the fuel system from the black connector beside the alternator. Jump it to the alternator.

Thanks ! will do!

 

[Heath]

Thanks Pronto! No leaks!

 

[Pronto]

Good to hear.

No leaks is a good thing...you will want to set the fuel pressure to about 43 lbs hose off at idle.

I assume I have to do something to the computer before it will crank? I have not turned the key yet. is there a tune in Fast when you get it new?

 

[Squid4life]

Depends on who you got it from. Ebay, no. Cal, absolutely. (If you gave him your build specs)

I just finished up my install recently. A few pointers, calibrate your sensors, move IAT sensor, set crank reference angle and make sure MAP has signal. I had some trouble getting mine to fire initially due to a bad map. It all worked out, now I'm working on the tune.

Huh??

[Heath]

Using Vista. I called FAST and got it connected. Called Jack at Cottons to make sure the tune is good enough to start. Now car won,t idle below 2800!!

Looking for vacuum leaks. not having any luck.

If I change IAC out do I need to unplug the orange wire like on the stock computer?

No. Just make sure you don't power on the xfi without the iac plugged in. It will blow the driver.

Actually, you can power it up with the iac unplugged. Just don't plug it in or unplug the iac with the ecu powered up. Lots of race cars don't use an iac at all without damaging the box

Maybe, post the tune and a data log or 2??
