Thread: Why is my vvl so hard to start

what fuel pump u have?

peace

I'm guessing its compression if it starts better when it's warm

Run the biggest gap without spark blowout. I've ran .039-.044 with no problems, your ignition might be different though.



Well there is your problem. Stock DE injectors are 259cc, VE are 333cc. Bigger injectors squirt more fuel per puslewidth, thus you need to decrease the duration of the puslewidths. This means if you run bigger injectors on stock ECU, you will be way too rich hence have issues starting like you are.

not sure of the specs rag, but here it is

when the engine is warm, it still hav a little stall

no u misunderstand, i hav the sr20 ve engine.

not the DE

which means the injectors r 333

But you have stock SR20DE ecu which is tuned for 259cc injectors, right?

no. stock ve ecu

Isn't the stock ecu for an automatic?

Unless it's a 16ve ecu which is manual.
