Re: failsafe setting
 

Last two days, I try to confirm failsafe and all of setting. When I smooth driving everthing is fine, but when I push hard and kept boost to redline, I found failsafe actived sometimes. Finial I found my jet 0.9 is less demand, so I replaced 1 .

WH a click or two C/W for WOT. Or FSDL C/W a bit.

Don't forget to recal S/C trimmer with 1mm jet.

Re: failsafe setting
 

I have a similar problem.

I have a built STi race car. I am running 2000cc injectors so I have dual 1.0 jets on the FMIC.

When I get on the throttle I get two led's ... then the injector led goes off and I get full flow.. 4 seconds later the WL goes off. Obviously I am briefly tripping the fail safe and then it goes off.

I have properly setup the fail safe on the gauge just as instructed. SC at 6 bars, the WH while in test and WL while on the dyno.

I cant seem to get the initial trip to stop. I have tried also delaying the failsafe with FSDL in the control unit/ gain.

What else can I try?

Re: failsafe setting
 

I had a long chat with Jeff just now, he has been working with you for a while.

A brief history, the system has installed a few months ago by a shop. They did not go through the initial testing procedure nor setting up the failsafe. It would be easier to diagnose and problem addressed at the time as all the components were brand new.


My first thought will be the following:
1. Clean the flow sensor is free of debris
2. Check for air bubble in line leading to the FAV
3. Check for the condition of the in-tank filter.

Yep Jeff is a great help.

More background.

The parts were nearly brand new. After the install the car sat in storage for the entire winter. Car only has 1300 miles on it and about 60 miles for the ride home with the kit on it.

I did take apart the sensor and cleaned it. It takes alot of effort to move the "wheel". I could not see fouling however, the wheel doesn't want to spin freely. After cleaning I reinstalled and got the same issue. For now.. I have sent the sensor back to Jeff as I think this is the issue. Maybe not but we will see.

I haven't checked the tank filter but I will next.

Thanks for your help. I appreciate you talking to Jeff about this issue. I am sure it will be resolved shortly.
