can a logger take place of a wideband o2?

[my98gsx]

I just installed a set of 650CC injectors into my car and i dont have a proper tune done to the car, nore do i have the money to buy a wide band o2 gauge kit for $350+... I do not have a logger and i know where i can get a kit for $125, but would that tell me what i need to tune the car? or would i still need to get a wideband setup?

You can go without a wideband, but it's always recommended that you have a logger. While the wideband can be useful in getting your air/fuel ratio correct, the logger will tell you much more, such as what your timing curve is, what your fuel trims are, and so forth. While you probably won't be able to take your tune to the hairy edge, you'll still be able to get a decent tune with your logger when you get the hang of knowing what values to read and how to properly interpret them.

Agreed. Logger first, wideband later.

Don't know if it would change your mind, but a cheaper wideband option is this. Only $279. Other than that, I agree with the other two guys.

I don't see an AFPR on your mods list. You will probably end up having some fuel overrun issues with that 255 pump.

With a wideband (on pump) gas, your tune should be between 11:1 or 11.5:1 (depending on how lean you want to go and what octane fuel you get). This air to fuel ration unfortunately does not tell you anything about how much timing you are running. You cannot see knock on a 2G (unless you get an eprom ECU), all you can see is thet timing curve on a logger and when there is a dip in the curve it indicates knock. Members have gone 11s in the 1/4 with a logger/SAFC without a wideband.

As said above, logger first, wideband later (if you have money).

Yeah i do have the inport Evolution adj. press regulator, i talked to slow boy racing and they said to bump it down to 39psi that helped me out, but i still need to tune off the afc..
