I am pretty happy with my stock FI. But after seeing some of the setups at Okteenerfest, I thought this might be worth trying.
The stock system is not easy to modify and get things running correctly. I spent a lot of time making minor adjustments by trial and error. While I am not looking for huge HP gains or anything, it is pretty clear that the mods I have could potentially benefit from a bit more precise control. Going to start with fuel only at this point to get things going and see where it leads me. Any help or suggestions for set up would be appreciated. |

Good Job. I used to take my 914 on long trips regularly. I was doing 20K in the summer months alone. This is the way these cars should be used. I really loved it. I think next year I will start this again Sounds like a great trip. The east coast is fantastic!! Mike (IMG:style_emoticons/default/agree.gif) The Megasquirt Hardware manual, page 53, the last section on the page explains ALL that you need to know. Just follow their recommendation and all will be good! From the manual: 4.10.2.4 Low impedance injectors - Injector Resistors This method has been used by many OEMs as a simple approach to driving low-z injectors. The installer has the option of installing a power resistor (typically with a 20 to 25 watt rating) in series with each injector (in effect converting them to high impedance.) The series resistors will slow down the opening of the injector slightly, so it is suggested that the resistance of the resistors be kept to a minimum but staying within the 14A limit of each injector channel. One resistor must be used for each injector - do not try to share resistors. For typical 2.5ohm low impedance injectors, the following resistances can be used 2 Injectors per channel - 4.7 ohm resisters per injector Following this recommendation is a photo and a wiring pictorial. Follow this and you will not go wrong. In the 914 World we may think that Megasquirt is new technology t has been around for over 15 years. The Megasquirt developers DO know what they are doing. |
