I need to pick one up to lean my car out a bit until I can afford to do another dyno tune.

What is the difference between the different versions that have come out in the last few years? I see v4.2 and 5.2 and blah blah.

Just want to educate myself because I will be looking for a cheap used one since its a temporary fix, and don't want to get the wrong thing for my application or whatever.

Thanks in advance...

 

hello?

 

i've got one for sale...120 shipped. Im not sure which version it is but i can check. I never had a problem with the unit. The diff verisons where just revisions to the circuit board for better design. Let me know if your interested.
