My goals

Car Specs


VEMS SETUP

I am going with v3.3 assembled. Here is the current plans, which are subject to many, many changes.

Components

Ignition and Injection Setup


Rewiring after killing an injector wire due to poor wiring

The ECU (which apparently is a v3.2 board has this mod using 0 ohm connections):

EGO Correction

I've enabled EGO correction to compensate for a rough VE table. This is the easiest method until I can get someone to drive the car while i learn how to adjust the VE table on the fly. It seems that EGO correction is not being turned on consistently and I don't know how to interpret what I see. What I feel is the EGO messing with small part throttle situations causing the car to hesitate. At full throttle conditions I don't think correction is being used. Feedback is appreciated.
