Tuning 03 04 Cobra

[Gmann951]

Putting a thread out there to get some info flowing on tuning these cars. Now that EECV Support is starting to roll out , I suspect that a lot of the SVT guys may shift from PRP to HPT.
Since there's limited information out there on tuning these cars compared to their LS counterparts I'm presenting what I have found scouring the internet over the past month. This is not a firmed and inclusive how-to, but the goal is to get it there with revisions based on feedback.

Note- that I have not tuned my own car (or anyone else?s car) using this method but hope to do so next summer.

Tuning the MAF

You are tuning this table: Airflow > General > MAF Calibration

The setup:

Airflow > General > Disable ACDC Switch/Anticipation Logic/Cylair Filter. This will force Load with MAF Failed to disable
Airflow > General > Disable MAP. Not sure if this sensor impacts calculations on early Fords but I would disable anyway
Fuel > Cutoff,DFCO > Deceleration Fuel Cutoff > Set all of the parameters to turn off DFCO
Fuel > Oxygen Sensor > Set O2 readiness to highest value to turn off O2s. Can turn off any other parameters you see impact closed loop
Fuel > TPS Thresh. Set this table to 1 that way you are always in OL
Fuel > OL/Base > Fuel Base. Set this to your desired WOT Lambda. I will be using 0.80 to be on the safe side
Spark > Advance > Borderline Knock. Reduce the by 5-6 across the border to be on the safe side while tuning fueling

If at WOT you are greater than 1.28 Load, then Airflow > SD > Peak Load need to be increased

Tuning Timing

You are tuning this table: Spark > Advance > Borderline Knock

This is straight forward you can do this on the dyno to be perfect or on the street to be close.

Tuning LWMF

Instead of using live VE data, these cars used fixed table data points to proactively calculate fueling to supplement the reactive calculations of the MAF sensor. It is important to tune this table as it impacts drivability. To tune this you need to leave it in closed loop and populate the data points the following table

Airflow > General > MAF Failure Load (IMRC Open)

At least in my experience so far I haven't had the need to tune the MAF table in closed loop as I have been doing everything in open loop. I haven't had to disable the ACDC anticipation switch nor the map sensor. I don't know if this affects data logging accuracy but I haven't had an issue yet. My only question right now is tuning my borderline knock table as it is hard trying to data log what my spark should be as I cant find a load sensor for my car in VCM scanner. So I want to know how people are finding load. Is it based on the MAF failure load (IMRC open) setting?

I don't have a ton to offer in this right now as I am now just getting into tuning, but hopefully we get some good info in here! Excited to see HPT giving us 03-04 guys another option for tuning!
