tweecer tech question

[04 Mach1]

I just about have the money up for the tweecer rt but need to know if i can read off of the cars O2, or will i need to buy a wideband o2 for the tuning?Just want to make sure I won't have any added expenses.

You can use the stock O2 sensor just as the CPU does and you can use the long-term fuel trims to get your MAF dialed in that way. Obviously, getting a wideband would be a more accurate way to measure A/F and it will allow you to do more specific tuning, but you can still do a good bit with the stock sensors.

I haven't gotten a wideband yet and I used the TwEECer R/T to dial in the Univer I currently have. The MAF was originally for a 2001 Cobra and is now calibrated for a '96 Cobra with 42# injectors. I have it working fine on my 5.0L with 24# injectors. :nice:
