How Do I Tune the ECU/Computer?

[Stinger]

There are a number of ways to do it, 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.

Is there a way just with the vam? And wideband?

[Stinger]

Sure, until the VAM maxes out at about 3800 rpm.

Oh okay

Does anyone have any experience with the quarterhorse as far as tuning goes? I am looking to go with SD instead of the vam and see the option to change it in the calibration.

[Stinger]

svojohn on here is probably the only one with significant experience with that. Most guys on here have a PiMP.

Which ecu do you have? The LSD.bin for the L-series ecu is the best SD code currently available. Even though its the best I can come up with it's still no match compared to a PIMP.

Thanks for jumping in here John. He's only got 1 post so who knows if he'll be back in here.
