SCT flash with stock PCM

[NogaBlitz]

I'm wanting to reinstall my stock PCM and flash it instead of my Stage 2 PCM which I currently have flashed. My question is this, since I already have the 3 bar map and tip sensors installed, will everything be fine if I just leave it the way it is or do I have to run the tip mod if I'm using the stock PCM? I'm an 05. My tip sensor is reading atmosphere as I have removed all the vac lines except for the boost controller and blow off valve.

If you do not plan to flash your stock PCM, you will need to revert back to the stock map sensor and tip sensor.

It doesn't matter if your TIP sensor is reading atmosphere, the PCM still uses the tip sensor even if no vac lines are going to it. Your fuel trims will be way off if you are using a stock map sensor and a 3-bar tip (or a stock tip with our jumper).

I do plan to flash the stock pcm. Just wanted to make sure that i could use my 3 bar tip sensor if I was flashing the stock pcm.

I just see it as a waste to flash my S2 pcm when I can sell it and recoup some money if flashing the stock pcm works just as well.


My S2 pcm is already flashed with one of your tunes, I want to flash it back to factory spec, sell it, and flash my stock PCM instead.

If you do plan to reflash then you do not need to change anything else wiring-wise. All that you will need to do is revert your stage 2 back to the stock profile, install your stage 0, and reflash your stage 0.

Wonderful thanks.
