Hey guys,
I'm considering doing water/meth injection on my car but I'm not sure what exactly I need. I have read that it needs to be tuned to adjust the AFR to account for the methanol, and that it will require a wideband oxygen sensor to tune properly. I would plan to spray 70/30 mix so I can just buy washer fluid. My questions are:
1. My canned tune currently commands 11.0 AFR at WOT. Instead of going to the expense of buying my own tuner, could I just have someone bump it to 12.0 or so and be good enough for meth?
2. If so, could I then forego a wideband? I don't really care about squeezing the most power out of my car, just want to drop a few pulley sizes without chipping a piston.
3. If I do need a wideband, can I just wire it up without a gauge? I'd rather just install the sensor if I can because I don't care about having an AFR gauge on my dash.
The reason I ask these things is because I don't want to spend $400 on HPTuners and $200 on a wideband kit if I don't need to. I know, I know, you can only pick two of cheap, fast, and reliable.
And if you have any experiences with water/meth you think would be helpful, feel free to share.
