A little background:

Last summer I installed an FP Red & FIC 1050's.

After running great for 2 months the car started becoming harder and harder to warm start after sitting for 15 or more minutes.

I replaced and checked MANY different things including:
IAC, vacuum lines, & gaskets. Switched to a DW300 fuel pump too. Fuel pressure regulator and solenoid.

I eliminated many things too thing that they caused the issue including:
EGR, Evap, and other emissions related components.

The whole time I assumed that the tune was perfect because it ran perfect for months before the problem occurred, and tunes don't change on their own.

Well I tried something today and I think I fixed it FINALLY!!!!!!

I zeroed out the last three values in the "Cranking Enrichment Adder (MAIN)" table
and now my issue no longer exists.

I really hope this helps someone,

thanks,
Rob J


UPDATE###########

THE PROBLEM CAME BACK THE NEXT DAY IT DIDN'T WORK.
back to the drawing board

 

My table runs from -32 to 82 degrees Celsius...so you zero'd out 50, 77, and 82?

 

Trying it tonight!

 

Don't bother the problem came back......

 

Well I was excited

 

My next move is to get rid of the tephra stuff and go back to a stock style ROM and try that out.

I heard from many good sources that the Tephra mods may be causing this issue on my car.

 

doubt that will fix it. i suggest trying a different set of injectors. call jens at fic, explain the issue, and see if he'll give you a good deal on a set of fic1100s (and an injector resistor bypass plug).

 

Shame.
I've not had an issue with hit start on ten or so cara ive installed 1050's on.

 

Some of the FIC1050s have it, and some don't. I actually worked on this with Jens several years ago. It is a leakage issue, and I thought he had found a solution, but apparently its not 100% effective.

 

Yeah I remember your workings on it a few years ago.

 

Or just do what I do. Half throttle, start engine, hold throttle until idle settles. Good to go.

 

That works for me... but aren't we flooding the engine with fuel at startup? Is there anything wrong with this method?

 

opening the throttle is giving it air not fuel, the injectors don't run on vacuum. you are thinking old school terms.

 

Back out the Biss screw one full turn and see if it fixes the problem.

That's not what I was talking about. The reason we need to open the throttle is because there is too much fuel, right? The injectors leak fuel after being shut off that's why it won't start... I'm asking if we are flooding the engine with fuel when trying to start it, because there is already so much fuel.
