Dont know that O2 sensor will be much of an issue Clone. It's only for closed loop correction and doubt the ECU will be allowing any more than 15-20% correction based on the sensor feedback.
You are better off working on your fuel enrichment via the maps, at least until you can get the car running reasonably well. Can you post a picture of your fuel map and a rough idea of the WB readings V's RPM?

I just looked at your screenshot again.
Is asynchonous pulse set to 0? Try 5 and see what happens. Read the info below as well.
Transient Throttle Enhance
Transient Throttle Enhance function aids in improving engine response when the throttle on a conventional fuel injected vehicle is opened rapidly. The Transient Throttle Enahncement works by adding additional injection pulses (asynchronous enrichment) and enriching the current fuelling pulses (synchronous enrichment) when it sees a change in throttle position. The setup allows the tuning of:
* How much enrichment is needed for a given RPM, start throttle position and TPS rate of change
* The biasing of the enrichment between asynchronous and synchronous types according to a given RPM
* The speed at which the synchronous enrichment decays
Note the rate of change of throttle position is how far the throttle moves over a 10ms time frame. A fast throttle movement could have a TPS rate of change of 15% this means that in a time frame of 10ms the throttle position moved 15%. A slow throttle movement could have a TPS rate of change of 1%, which means that in a time frame of 10ms the throttle position only moved 1%.
Settings
* Number of Async Pulses - This is the maximum number of extra injector pulses that can happen per injector output during an enrichment event.
* Async Delay Time - The minimum time between asynchronous enrichment events. This is to stop excess fuelling when constantly pumping the throttle.
* Delta Dead Band - To prevent excessive enrichment due to slight throttle jitter, only a rate of change of throttle position greater than this value will trigger an enrichment event.
* Transient Throttle Trim - The trim value scales the fuel enrichment. 0% makes no change to the fuel enrichment. 100% will add an extra 100% to the enrichment. Setting this to -50% will remove 50% from the enrichment.
Transient Throttle Tables
Enrichment Sensitivity
This map allows for the tuning of the amount of enrichment needed according to a given RPM and starting throttle position. In general more enrichment is needed at a low throttle position because a change will cause a larger in rush of air than at a higher throttle position. At a low RPM more enrichment is needed because of low air speeds and the atomisation of fuel is poor. This becomes less of a problem as the engine goes up in RPM and airflow increases.
The value in this table represents the enrichment needed at the maximum Delta Load. The maximum Delta Load is the largest change in throttle that you can make in the sample period of 10mS. In simple terms, this is the amount of enrichment for a full throttle opening as fast as you think you will ever open the throttle. Display the Transient Throttle Delta Load channel on a display or gauge to determine the magnitude of maximum Delta Load that you can achieve.
This table is the first to be tuned but also make sure that the right hand column of the Percentage Enrichment table equates to the maximum Delta Load that you have selected.
Percentage Asynchronous
This table determines what percentage of the fuel enrichment is delivered as asynchronous enrichment. Setting 0% in the table means that all of the fuel enrichment will be delivered synchronously (ie no additional fuel pulses will be added, all enrichment will be delivered by increasing the regular injection pulse). Setting 100% in the table means that all of the fuel enrichment will be delivered asynchronously (ie the normal injection pulse remains the same and all the enrichment fuel is added through extra asynchronous pulses between the main injection pulses).
Note that if the enrichment value exceeds 9.5ms (the maximum size of an asynchronous pulse) the remaining enrichment will be delivered synchronously.
As a guide, at a low RPM, when the injection events are short and further apart, the asynchronous fuel enrichment helps deliver the extra fuel where its needed. At a high RPM asynchronous enrichment is not needed because regular injection events are more frequent.
Accel Ignition Adjust
This table allows the ignition timing to be adjusted during transient throttle events. The correction is an adjustment on the overall ignition timing value.
Percentage Enrichment
The Percentage Enrichment table allows you to proportion the amount of enrichment depending on how much change in throttle (Delta Load) that you make at any transient event.
The Enrichment Sensitivity table above is tuned for a maximum Delta Load event. To accomodate lower Delta Load events, the Percentage Enrichment table is applied.
The right hand column of the table should contain the largest Delta Load value in its axis value and 100% in its map value. This value should have already been determined when setting up the Enrichment Sensitivity table above.
E.g. If you anticipate that the largest throttle change that you can make in the sample period of 10mS is 25%, then the axis value should be set to 25%. The Enrichment Sensitivity table values are based also on this largest Delta Load case, so in the right most column value, you should set 100%.
For slower throttle movements (lower Delta Load values), less enrichment is required, so values less than 100% should be set in these columns.
Enrichment Decay Rate
This map determines how fast the synchronous enrichment (i.e. the enrichment added by extending the normal injection pulse) decays back to zero (no additional enrichment). The units are milliseconds per engine cycle.
E.g. a value of 0.5 will mean that the enrichment will decay 0.5ms every engine cycle. The bigger the value the faster it will decay.
Accel Ignition Decay Rate
The rate in degrees per engine cycle that the ignition offset will decay. The larger the number, the quicker the decay.
Coolant Temp Corr
This map applies a correction factor to the fuel enrichment based on the coolant temperature. E.g. 100% gives 100% extra fuel enrichment.

Diamonds are forever....
What throttle body are you running? What is the TPS off? Does the new TPS not have a built in throttle closed switch which would give you a constant state of throttle closed?

standard gsr throttle body and tps. No idea how to check if there is a throttle closed switch though

doe the plug on the tps have three or 4 wires?

then it has the throttle closed switch in the tps. but i'm preety sure the haltechs don't use the throttle closed switch anyway at least mine doesn't
