If you want the car to run better I'd recommend spending the cash on Hondata over using a chrome chip but for budget minded people either one of those sites I listed can get you taken care of.

I agree with EB though. if you have a little cash to spend you can get a s300v3 that will give you so many more options in the long run. Blue tooth compatible now too. :) My p72 is currently getting one wired as we speak. Can't wait.

Good luck. :thumb:

- Wed May 20, 2015 12:54 pm #353829 Street tune with a wideband AFR sensor? Or the more common add fuel and timing I just picked up a laptop for the first time and wanna try moving these graphs around tune?

The reason I ask is because a street tune will typically be an experienced tuner using a known safe timing map from another car they have dyno tuned with a similar setup and then mapping fuel while you drive on the street under many different load conditions.

A lot of young guys go to their 'friend' who 'tunes' and he burns a chip with a map he downloaded online adds a ton of fuel, timing, and a 3500 rpm two step and calls it a street tune because there is no check engine light anymore.

Just be careful of what they are doing before you buy it there is a big difference. I do a ton of sidework from home and about 75% of the modified egs that come in have the second option and get upset when I want to charge them to put in a known working ECU before going any further into diagnosing an issue.

A lot of people install an aftermarket intake manifold without them but if you go that route, you really should get the car tuned on a dyno. The added benefit to swapping the manifold is that you then have a lot more intake choices but as for me personally, I prefer to keep the original 2 stage manifold.
