Let's say it showed 10.5 during cruise which should be 14.5
Then WOT looked to be around 8.8 on average which would be 12.8 (little lean for FI C7, hence your second nozzle which is around 10gph guessing which would put you close to 12.0)

it is the Innovate Motorsports PSB-1 gauge. It does have the ability to be calibrated outside of the exhaust for free air, which I performed according to the instructions before installation.

psb1 has the ability to choose fuel types so if it is showing 10, I assume you have chosen E85?

it appears that PSB-1 will show 14.87 as Stoich if set to Gasoline (E0) which means E85 would probably be right at 9.97.

That is the problem with AFR.
Can you set it to Lambda?

use lambda then, it's going to be 1.0 for stoich and you want to see between .80 and .84 at wot, depending on a few things and the tune.

if you are below .8 you are definitely too rich and above .84 is, imo, too lean for a boosted di motor.....

when we first started boosting the LT1 everyone thought they want to run lean like NA but I think that's just because we didn't understand the ECM at the time.

anyways, if you get a chance to test the afr using lambda, let us know!

so I am trying to connect to my car and pull the tune. Either I just don't know how to do it, or it simply won't let me..

. What are the proper steps to do this? Note: I do not have the "application key" for the software... just the physical tuner device. I downloaded the latest VCM suite off the interwebs, and tried to go into Demo mode. I then tried opening VCM Editor, and do "read entire VCM" but after I click "begin" that is when it fails. What am I doing wrong here..?

Ok I put the gauge in "air" mode and set it to show Lambda. WOW... It's running WAY too lean. No more pulls until I put the second meth nozzle back on. Vid:

During all these issues you've had do you always see "02 Cut" come up? Doesn't that mean it's cutting off your boost due to AFR issues?

the gauge has the ability to cut boost if the boost regulator is hooked up (mainly for turbo setups) but i do not have that hooked up since im supercharged.. So, regardless of what it says its just functioning as a gauge..

Right, I was just saying if you have always seen that coming up then you must have always been running lean which your tuner would have seen during testing.

I dont think it will let me. The HPT was previously used on Rob's Pontiac G8. I dont think it will let me do anything with it until I get the activation key. It keeps telling me "Invalid Cable ID. You do not have license support for this interface"..

it's not the car its the laptop. use his laptop or it might work on yours if you open the software and plug in the cable, go to Help, License Information in 2.25 and see if you can click something in the box to refresh it. In 2.24 go to Help, License Info and click the top left HPT logo/icon to pull the interface info into the software.

you don't need to license the file to pull it and email it.

this post leans me to a bad plug or wire or coil. any of the three would give you a CEL. hopefully its a cyl misfire code and you can go to that hole and fix it. Also, I wouldnt "clean" the plugs with those old style plug cleaners, they are for lawnmower plugs mostly not these expensive hi tech ones like we use with iridium and titanium etcc...... if can actually make it works. a new set of plugs (save the old ones in case you need one in a pinch) aren't cheap but fowling a plug that's in a car with high rpm boost can be BAAAAAAAAD once a plug has seen some over rich condition or flooded especially they never seem to perform quite right. pretty easy for an unclean plug to misfire under the right conditions, usually under a heavy load or stress at higher RPMS. if we could hook your car up to an oscilloscope I could show you electronic proof some of them are weaker then others. The meth guys seem to be leaning you to less meth, sounds like you just need to get with your tuner it get that dialed in to be safe as well. keep us updated, very interesting thread bro

I put brand new plugs in it yesterday. Problem still exists. Waiting on new wires to arrive. hopefully Monday at this point. The CEL never produced a code for me to follow up on that night either..

try this, do you have a log on for HPT profile page? log in, go to your Customer Page, and click Email most recent application key and then put it in there.

I Don't have a log on, no. I was going to talk to my friend about it tomorrow to see if he has his login. I assume it would be a bad idea to try to re-register the serial number with a different email address anyway so probably best to see if he can get signed in to the page to get the activation key.
