Greddy TT kit finally running...but 1 problem
OK so wow!!!!!!!! my car is finally running after about 4days straight of working on the car. And so it runs really smooth i love it, its amazing but one problem i am having is starting the car the first couple of times it was fine but so far right now when i start it now it dies but if i start it and give it a little rev it will go back down to idle with no problem at all and act normal. Has anyone had any similiar problems or does anyone know what might be causing this?
Welcome to the club! Maybe we should get jackets
Like guru said a lot of the greddy kits start up funky. My doesn't die but drops to 500rpm for a second then jumps up to normal idle. If I do a warm start ( were the cars already up to temp) it does not do it. I think it's the 440 injectors. They are a 3 hole design and the factory is a 4 hole.
I think do to the larger size ( less control at short pulse) and poorer spray pattern when the fuel and engine are cold, the fuel doesn't mix well. That's why I only see it at cold starts.
I bet the guys that went with the TS reflash and 380 pe injectors don't have this. The 380's are 4 or 6 hole designs. If they do then I guess my theory is shot.

Yeah, I'm a member of the club as well. 
I think it takes the emanage a second to load up, so if you turn the key from off to start right away the emanage has not initialized. Also 7 eleven your right, I cannot imagine the emanage being able to cut a 1 ms pulse down to a .6 ms pulse with any accuracy.

haha...all i have to say is wow, didnt realize so many people have the problem as well. I guess its not exactly a totally good thing but it does give me some comfort b/c i didnt want to think that we did something wrong, or that i have something defective! But hey thanks for all the info guys!
As for the jackets as 7 eleven stated, Greddy sent me a Greddy jacket and a free T-shirt along with a catalog. All for free. I just sent them a copies of my receipts of the TT and intercooler and 2 weeks later free stuff. THe jacket retails for $50.

I have the NGK Irdium heat level 7 plugs which are one step colder than stock. I don't have any start up, idling, or dying issues. Idles like stock. However, when I start the car, it takes about a 1/2 sec more cranking before it comes to life. Could it be my plugs that are helping the situation? 350Now's TT also starts and idles like stock...I heard it myself.
