Trimmers
 

Got around to road testing to set the lower failsafe today.I had the two jets under the drivers wiper blade, so I could see it spray.It started to spray before I had even got on boost.I stoped and turned the Thres pot clockwise.It did better.I ended up with the adjustment all the way clockwise and it still starting to spray at only a few pounds of boost.I need to get it where it starting at around 10psi or so.So what needs to be done to get me there.Starting at 3lbs of boost is a bit too early.

Thanks, Philip

Do you have a map sensor on your car?

Re: Trimmers
 

No Map Sensor.

What car model is it?

Re: Trimmers
 

Its a 1994 Toytota Supra Turbo.I thought I had sent you pictures of my setup.It has a HKS VPC.

Re: Trimmers
 

I cannot remember.

I have some questions

1. Are you using large injectors
2. Are they low impedance injectors?
3. What is the maximum duty cycle seen at WOT

I think there is some IDC signal mis-matching.

Re: Trimmers
 

They are stock low imp injectors.I had sent the controller to Jeff, whom I purchased the kit from, to modify the board for the injectors.I have just got it back from Jeff and was trying to get the defauts set when I noticed how early it was spraying.I called him, and he told me to turn the THRES clockwise to get the system to start later.It is turned full clockwise now and is starting to inject at about 3lbs of boost instead of around 10 where I want..

Re: Trimmers
 

I need a bit more information from you please.

Which harness are you using to pick up the injector signal?

Re: Trimmers
 

I am running the green harness that is connected to the + and - of the #1 injector, at the ECU.

One more question, what is the serial number of the controller?
