The vortech kit I got did not have the FMU in it. I honestly am not sure what my options are here as to get one, get something else or what? I can reward any help with all the money in my left front pants pocket and a piece of gum. Hubba bubba grape flavored if that sweetens the pot!:thumbsup:
Bigger fuel injectors and a tune is what you will need. Or you could go the route of fuel injectors and a maf sensor that is calibrated for them. That route would require you to also run your timing locked or use a boost timing retard box to pull out timing based on amount of boost. When I first got my car which is running a v2 up to 16 psi, it was setup with a msd 6btm to handle pulling out timing, and 42 lb injectors with a matched pro m maf. Now I have the btm still there, but im just using it for the cdi ignition, it no longer even has a vacuum line ran to it. The maf sensor died, and went into the trash. Instead of spending another 300 bucks for a maf, i bought a Megasquirt Pnp ecm to handle everything using speed density. I would stay away from the fmu all together. I would get the biggest injectors you can get a good deal on myself. The 42's work for me right now, but it doesnt leave me much wiggle room for slapping on a smaller blower pulley. Anywhere from 42-88lb running will be fine using gas. E85 alwayss require bigger fuel injector to make the same amount of horsepower
so it can be done through a tune and bigger injectors? I already upgraded the fuel pump to a 255 I think it was but I do have the tank out currently if I need to increase it as well.
You are correct. Bigger injectors and a tune are all you need. The 255 pump should be fine as well. I would highly encourage you to get a tune at a dyno verseus any mail order tune. That way they can physically see what the engine needs and adjust in right then and there.
no need to convince me that dyno>mail order I already learned that lesson. My only possible problem there is that the shop is about an hour away. I have a 2nd chip that I am hoping he could throw something conservative at to get the car down there...
