OK … as a preamble, my posts tend to be to the point, but no negative connotation is intended nor implied.

At the outset of this project I recall two things in particular. One, that you had a similar setup in another vehicle that operated well, but that you had purchased this tune. Two, I recall a “spirited” discussion regarding tuning options - MAF only, SD only, and blended MAF & SD (OEM style).

Fast forward to the present … your induction configuration does not include a MAF sensor, which effectively eliminates 2 of the 3 tuning options. This is not a problem for an experienced tuner, but is not an optimal situation for a novice tuner. A novice tuner may find a MAF only tune as the most simple way to begin the tuning process. As experience is gained, working with the VE table(s) becomes less intimidating. Eventually, this may lead to migrating to a blended tune (MAF & SD), or even to a pure SD tune.

The tune you posted is an open loop (OL) SD tune - which means there is no fuel trim afforded by the PCM via the narrow band oxygen sensors (NBO). Again, while not a problem if the VE table and / or MAF table are highly accurate, it is generally not the most forgiving configuration for a street driven vehicle. Properly used, the short term fuel trims (STFT) can be very beneficial.

The above process requires the use of a wideband oxygen sensor (WBO). I would not run this engine at all without a WBO connected. The posted tune with respect to airflow, is virtually stock, and is not representative of the engine’s new forced induction airflow dynamics.

The question you need to ask yourself is, can you reasonably learn how to tune a forced induction engine, within the time frame allotted for this project. With an open ended time frame, a WBO, and a great deal of self-education, I have no doubt that you could do it. Sometimes a quality dyno tune is money well spent. Just something to think about …….

When you finally obtain a WBO, I foresee future questions regarding how to connect it to your V2, and how to configure the PIDs.

There was a gentleman on the EFILive forum that would walk people through their tuning projects from beginning to end. Sadly, he passed away.

I have neither the time, nor the inclination, to provide support at that level. I try to answer questions, point people in the right direction, and assist with their decision making processes.

If you decide to try and tune this project on your own, I would recommend not running the engine further until you have a WBO connected.
