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. |

Seriously. Low impedance injectors need a resistor pack. 1.8 engine had them. Use one of those. Done.

I know some of the discussion may seem trivial to some but this is how we learn.
Agree or disagree. Not really relevant. This will be a long process for me and I will always welcome input. Some of us may learn a few things along the way. Thanks to everyone for helping out. |

Some of us may learn a few things along the way. Thanks to everyone for helping out. A couple points to bear in mind as you are soaking in all the info you can and as you decide what and how you are going to proceed. Low impedance injectors with resistor packs have been used by several manufacturers and yest this slows the injector opening but it is insignificant, especially if you start think about the speed of the analog D-jet/L-jet systems compared to the speed of a digital Mega/Micro Squirt system. Keep it simple, there are a lot of people that have set up Mega/Micro Squirt systems that are not engineers or techo wizards. Don't over complicate a setup, it is not necessary. If you are going with MicroSquirt rather that MegaSquirt, be sure to reference the MicroSquirt manual for specifications. There have been a few thing referenced in this thread that were from the MegaSquirt manual. The 2 systems are very similar and many thing apply to both but some things do not. The specific reference that I know is different is the amperage rating for the injector drives. MegaSquirt has a high amperage rating on the injector drivers than does MicroSquirt. The MicroSquirt drivers/heatsinks are smaller to fit in the smaller ECU housing and can only handle 5 amps (per the MicroSquirt manual) I don't know how or what other differences exist and my focus has been on learning about MegaSquirt, since the car I bought had a MegaSquirt equipped engine. It is not up and running yet, so I am just studying the system for future tinkering. Good luck Jim |
