socolax91, did you solder yours or was it P&P. If Soldered, you might have to check your work on the wiring harness...

I highly suggest you find a buddy with a laptop and check this out. Definately should not have a CEL with a stock URD Map setting. And even the one I seen for TRD CAI, and exh was pretty much all 10's in each cel.

When you get the software up check out this site:

So you are saying that I might be getting an engine code because the map is incorrect?

Could be, or could be your connections upon install. URD is pretty good about their products. If you ordered it pretuned, then I would think it's your connections.

I went through a whole day of process of elimination and all with my APR setup. You just got to eliminate all probable causes til you find the culprate.

I'm about 90% sure my connections are correct but there is always that chance.

Gadget Came!!!!! HE IS THE MAN!!! Thank you sooo much!!!!

It was my fault. URD did perfect. I wired it up wrong. After looking at the same ECU for 2 hours everything just looks right lol. Gadget came and fixed the problem in 20 mins.

Thanks a lot. URD ROCKS!!!

Urd maf cal

I just ordered a maf cal from urd. I was wondering what type watt of soldering iron is recommended and what type of flux solder. Also are most of the connections splicing or tapping into the wires.
