I was wondering what cranking percentages you guys are using and what you would recommend for my setup. I have had the motor tuned and on cold start up it is running excessivley rich. I am using Hondata S300 and I am wondering if I can remedy this with changing the cranking fuel percentage. Any information would be greatly appreciated.

My Setup
Head:
B16 (stock port)
RC440 injectors
Supertech Valvesprings
Supertech Valves (flat faced)
Supertech Retainers and Locks
Pro1 Camshafts
Stock Cam Gears
Victor X Intake Manifold with Hondata Gasket
4-2-1 header (no name)

Engine:
LS/Vtec
Golden Eagle Sleeves
Wiseco Pistons (~13:1)
Eagle Rods
Stock Crankshaft (Balanced)
84mm X 89mm

I am also using a stock fuel rail and fuel pressure regulator. I have a Walboro 255 pump in the tank. any other questions I will be happy to answer.

 

There are no magic numbers that work for every setup.
It's called tuning :-)

Tune the engine coolant temperature versus fuel tables, then tune your cranking fuel & post startup fuel.

 

Your talking about the fuel compensation table of the ECT sensor to the fuel table correct? If so I will have to try that method. I wasn't looking for a magic number though I was just kinda looking into other peoples setups that use E85 and seeing what you guys thought. I understand every motor is different but I didn't even think about the richening process of the cold start from the prospective of the ECT sensor. I appreciate it.

 

you can add a bunch of timing below 1500rpm also especially if you are rich already. I never had problems with E85 until below zero and I had to be extra rich on light off. Also the IAT correction tables should give you some place to add or subtract fuel also.
