I was going to buy one of those to put on my CarPC but then decided to buys a Scanguage II, its better because it will tell you everything that will and you don't need a computer and I dont need to run the PC to see my MPG and all that good stuff.

 

eh im not lookin for mpg or anything like that. Im just getting a free laptop hopefully and was just curious. i just wanted to pretty much tweak the a/f. iseen you talking about a carputer. those things seem pretty slick and i have seen cheap bare bones for them

 

Stock O2 sensors are narrowbands, not wideband. It doesn't show AFR, just lean/rich of stoich. Also, you can't 'tweak your AFR' with just OBD-II, especially not on the A32.

 

That stuff is great for getting info about your car, but not tuning.

 

thanks for the info guys. i suppose i would have to have some kind of piggy back to tweak the a\f huh

 

No, just an AFC.

 

Piggyback/AFC, same thing IMO.

 

I personally consider an EU, EB, something of the sort a piggyback, but not an SAFC/VAFC etc. True though, that AFC's do technically qualify as 'piggyback'.

 

<----- Tends to agree.


Data monitoring/logging is a very powerful tool. Although it is limited in this case by the 'slow'(todays standards) A32 ECU.

 

The A32 OBD-II interface is slow even by the standards of a 68k PowerMac...

 

Get yourself a WB02 with data logging and VAFC and you are good to "tweak" your A/F ratios. Did you change anything drastic(headers / exhaust, injectors, MAF ect) on your car or you just want to see if the A/F ratio will do anything for you??
