Can I Add Larger Injectors?

[Stinger]

Yes, you can add larger injectors, but only if you have a means to tune the ECU. You will need to use low impedance (low z, 2-4 Ohm) injectors only.

Without a way to tune the ecu (below), you cannot add larger injectors without causing other issues.

There are a number of ways to tune the stock ecu, depending on how you choose to do it:

Option 1:
$60 F3 Adapter
$Free EEC Editor Software
$75 Jaybird J3 Module Reader/Programmer
$200 Innovate LC-1 & Sensor (or something similar)
$335 Total

The F3 option will allow you to run the car, watch the wideband gauge to see what the air/fuel ratio is doing, then go back to your computer and burn a new tune on the chip, and plug it in and go for another drive. Kind of "clunky" but is a cheaper option that many people have used with success (including myself).

Option 2:
$250 Moates QuarterHorse
$130 Binary Editor and EEC Analyzer
$200 Innovate LC-1 & Sensor (or something similar)
$580 Total

This option does realtime tuning (engine running) as well as realtime datalogging of all parameters. This is certainly the best "stock ecu" option going right now. Should make the tuning process a lot less time consuming but is more expensive than the F3 option.

Last thing you need is some knowledge of what turbo engines need as far as timing, fueling, etc. is concerned.

with option 2 a little more money you could do a mass air swap correct?

[Stinger]

You can do a mass-air swap with either one of them, it's just easier with the ability to datalog in option 2. Note it will cost another $150-250 or so for the maf stuff (meter, filter, flexible connections, couplers/clamps, airflow straighteners, etc.)

Or you can just pick up our standalone ecu when it becomes available and have a more capable, easier to tune setup for around the same cost...

What is the problem with using a high imp. injectors, just wondering :0

[Stinger]

The factory ecu is designed to control low imp injectors so that's what you're supposed to run. High imp injectors won't burn up the ECU or anything but they won't run "as designed" because their opening time and other characteristics are different than low imp injectors.

Aah i see, thanks
