I never threw a code until I added my latest mods. I searched first, so please don't jump on me for asking. I want specific recommendations for brands and models. There are a bunch on Ebay, at AutoZone, etc. and I don't want to waste my money if the simple $24.95 model is a piece of junk.
On the other hand, I'm not interested in DataLogging. I assume some of the cheap ones are much slower than others and so forth. Suggestions anyone?

I've been resetting it manually, but it would be more professional to read and erase the codes electronically. (I sometimes have to try more than once to get the gas-pedal shuffle just right)

Thanks,
Bruce
