injector cleaning and calibration

Do not talk to me while you are in the mountains skiing. I can't hear you......la la la la la la la la la la la la

Only Pranav.... Shooshing through the picturesque winter wonderland thinking about CMC fuel ratios. What is wrong with us?.....

I've had 2 sets cleaned, both entered within a few percent and left within 1-2cc/min of each other. Stock LT1 injectors generally get turned away. Apparently the colied wire that forms the electromagnet to open the pintle has insulation that gets washed away not only by fuel over time, but also more aggressively by the compounds they use to clean the injectors. One of the reasons stock LT1 injectors blow. There are certain LS injectors that play nice, but you really need to do your homework.

Yeah my injector shop told me to get rid of mine the 2nd time around.

They call us gearheads for a reason. Some of these chairlifts are long, lots of time to think.

yah having the sensor back that far will throw off the reading a little. I have always installed them just after the header connection and before the X pipe. It says in the instructions for those gauges too to mount it as far forward as possible.

I'm sure you are correct about the sensor needing to be in the front O2 bung but if so how does the computer get info on each bank if it only has one O2 connected to the computer? The rears are after the X. I guess I need to re-read the instructions.

use weld in bung that comes with the gauge and weld it in after front 02 but before X pipe

Next race features a cigar and brandy corral with vacuum leak detection

IN the Rockies, I just have the dudes next door bring over their bong.

Don't act so innocent, it's not like you have to piss in a cup anymore.

Was the car running hot at all when the AFR got worse? If not it may just be a garage accuracy issue.

[ShadowBolt]

No it did not run hot. Also I posted this but my post has not shown up. All my O2's are prior to the X. I run the stock units in the front two and elimanators on the rear with the wideband in one of the rears.
I just got the engine out and this all may be PVC related. Oil burned on every piston and I was filling up the catch can every two races. Normally we don't get two ounces out after a whole race weekend.
