ok guys here is my situation. I had my car sent in to a local shop to have alot of mods added. The just installed a singe T04z kit with 850/1680 primary/secondary injectors with all the other proper single turbo mods. The shop tried starting the car today and had a spark and fuel, but was not turning over. I have read the PFC manual and change all the injector sizes and the timing #'s. They are not familiar with the PFC and they believe it is a timing issue.

I guess what I am asking is, is there a map i can install for break in purposes ot just to get it started? I am planning on running the car at least 700mi with no boost and have steve kan tune it when he comes up here in may.

 

If you change the injector sizes, the car should start and run with the base map with no boost. Idling is more effected by the 850cc inj than anything else you've done, count on it running super rich at idle.

 

thanks

 

Ok, I have 10ohm resistors connected to all of my injector clips. I have been doing some research and it sounds like some of people are having some problems with the 10ohm ones, I guess 5 ohm seems to be pretty popular. Although there are a few people running the 10 ohm ones and having success. Anyone have any insight on this? Are 5ohm resistors the way to go?

 

The resistors are only needed on the low impedance Bosch 1600/1680 plus.
Not to the 850s.

You want the resistor resistance + injector resistance to be high enough to not flow over 1.5 amps.

Normal alternator voltage is about 13.8 volts

13.8 / (total resistance of injector + resistor) <= .5 amps.
