3.4L supercharger

Anyone have the "vehicle specific connection guide" for the URD AIC/TC (7th injector computer)? My truck is a 2003, so a document for an 03-04 is ideal, but I can work with another version to see how much hacking up of the harness I would have to do instead of buying a $400 Boomslang Harness extension (BF13010) to tap into rather than the OEM wiring.

 

I really need to get the AFR and timing calibrator at the very least. Im running rich I'm noticing more and more lately.

 

It's unclear what features are included with the URD Additional Injector Controller / Timing Calibrator [AIC/TC] (included with 7th injector kit) includes. This vague phrase makes me think that it connects to the MAF since our trucks don't have a MAP sensor.
The injector is controlled using map B in the R4 tuning software and it is a true 3 dimensional map table based on Manifold Pressure, RPM, and the amount of injector on time in milliseconds.

So then IF the AIC/TC has that, there shouldn't be the need for the separate URD AFR Sensor Calibrator. But then this phrase on the AFR calibrator page makes me think that the AIC/TC doesn't do anything with AFR:
The URD AFR Calibrator could be used by its self or with your current fuel controller. However it is best used in conjunction with a MAF signal calibrator like our URD Fuel/Timing Calibrator.


**EDIT** The AIC/TC contains an internal MAP sensor

 

I will get em on here tomorrow. Looks sick. I love second and third gear.

 

Here’s a photo taken now.

 

John,
We gotta meet up again for pointers on driving, running high RPMs and low RPMs. Also I don’t know what to listen for yet. Thanks

 

Anytime,

get those 400-500 miles in for the ECU to be reset and then we can meet up again.

Give yourself some time on the stock pulley and get then get yourself a Christmas present with. 2.2 a pulley.

How did the intake valves look?

 

Thanks! They looked good. The mechanic said it was super clean. Second gear torque is as much torque as first. It just goes. It’s nice. I’m just not sure if I can be in 4th at 2100 RPMs or third at higher RPMs.

 

With the stock pulley probably you can, it’s the lugging where the ping will come on 1st probably

 

Im feeling that it doesn’t like the lower RPMs. It would rather be in the lower gear and a little higher RPMs. So I’m just feeling it out and listening to it carefully.

 

That's the way to do it, especially if you have a manual trans...high gear/low RPM is ping city if you get into boost. Best to wind up the RPMs in lower gear. If I'm loaded down with weight pulling up a slight hill on the highway I won't even touch 5th gear

 

That’s what I’m feeling when I’m driving. Gotta downshift to boost. Like you said, can’t stomp on it when the RPMs are low. Gotta down shift.

 

Another photo this morning.

 

Well, I emailed URD to see if I can get the instructions.

 

Peeled out with Goodyear wrangler Duratracs. Gave a Jeep trail hawk a run for its money. Actually smoked it. I used a tank of gas today. Haha.

 

I guess that means your ECU will be reprogrammed pretty soon

 

You got that right!

 

You can get the 7th Injector AIC/TC to come with the AFR/O2 calibrator (closed loop enrichment) built in. That’s how mine is. Only need one piggyback.

 

It’s eats up hills. Tried to go to Keystone but turned around at Genesee Park. Too much traffic. Everyone was going to the mountains.
