Thanks guys for your input. I had the O2 signal pin a spot off. Everything is working well and datalogging. Will still move my sensor back when I put the other motor in. And, for those that are...

So...the swap went very smooth and have to say, im very impressed with the way it runs open loop. The only problem is, it wont go closed loop. I'm getting the O2 failed code. I had installed a heated...

Going to do computer soon as I can, I want to see the difference it makes. Probably wont do bottom end swap until fall, maybe later if I like the way the 7427 runs current engine.

I found a BJYL 7427! :jfj: Now, I need to find some time and order a G1.

I occasionally do work for a salvage yard. Checked today and they only had one for a V6. But, I'm keeping my eyes open.

Thank you roadknee and davew! Sounds like the exact direction I want to go.

Will 1.6 rockers on the intake side have any negative affects on the o2 sensor? Is my exhaust sufficient to do so? Any guide clearance issues?

Shorty headers into a 2 1/2 to 3" flowmaster collector to high flow cat to 3" vortex muffler. Not sure about shift points at wot. I'd definately be more interested in part throttle response/ mpg. I...

Been thinking about going with a 7427. Besides finding a fried 7747, do you know of where to find a plug-in to make an adapter? I just want to reduce downtime of the truck, since its a driver. That...

Just picked up some srp inverted dish pistons, 6" I beam Eagle rods, Eagle 383 crank and a Vortec block. Compression ratio is 9.8:1. I have a 91 C1500 rcsb built 700r4 with 3.42 rear. Not looking to...

Well, after dealing with a failed fuel pump, I did ALOT of reading,soldered in a G2, burned an ADSU bin and datalogged. Long story short, my second chip runs way better than the "custom" mail order...

Have you checked the fuel filter? Could be clogged, not allowing enough fuel during initial prime?

Was ready to start datalogging :( Now I'm having a fuel issue. I shut off the truck and it wouldnt restart. Next morning it primed, started then stalled out. Wouldnt prime or restart. 100% sure the...

I found out the hard way :( I'm eventually going to go the burn2 route. Do you have a recommendation for a zif socket? The one dave w mentioned in the 7747 flash conversion post seems to be on back...

I will be messaging you EagleMark, once I get to datalogging. It isn't a stock chip, tbichips :) looking forward to your help.

Alright, it has been awhile since I posted on here. Truck started running poorly, even moreso since it got cold. I'm patiently waiting on parts to build a cable for datalogging. In the...

So, to start data logging, I need Roberts USB ALDL cable and tuner pro?

And thanks :)
