Joe, attached is my current tune and datalog from yesterday. As always, thanks for the help. I appreciate it.

Joe, we finally made a step in the right direction. The ben from WB is an average of .8064. I'm not sure what I have changed but for some reason on the ben map it is only taking data on the far right...

I'll do that and I'll let you know tomorrow what happens. Thanks Joe

It's showing lambda but I know I set up the LC2 for AFR. Or should I have changed something elsewhere and didnt catch it.

So I have a new problem. I have discovered that when I select the pid external wideband controller, the wideband information comes up like it should but I am using a LC2. When selecting Base...

I believe you, but is it wrong because of the way I have it setup or because of the injector data causing a problem? Just having a hard time figuring out what it is supposed to look like.

I didnt catch the wideband not working. I think that's the first time i've not seen it work so I'm not sure what happened but I'll look into it.

Greg Shaw asked me to start this new thread and Greg, I greatly appreciate your help. First of all I am using the engine from a 99 Chevrolet Silverado. The ECM from a 2001 I believe with a custom...

I hate to ask but I'm stuck and can't seem to figure out what I'm doing wrong. I have a bone stock gen 3 5.3 with twin turbos, decapped injectors, 3 bar map, and 4L80E. I have received a tune from...

Joecar, no I did not have it scaled appropriately. I increased the fuel pressure to 55 running with the vacuum lined hooked up but I need to find the correct information on scaling the injector...

I posted up a tune and datalog in the first two post but I'll post the updated tune. The data shows that it is running plenty rich. At part throttle is tries to make some power but when it goes into...

Ok I totally misunderstood the injector flow rate. The injectors I purchased were rated at 60 lb/hr @ 43.5 psi. Therefore I assumed that they had to be ran at 43.5 psi. I have since then increased...

I have just replaced my 2 bar ebay MAP sensor with a genuine GM Cobalt SS sensor. Still no difference in how it ran but I did finally notice that when the truck is missing while at idle, it's because...

Hi guys, I have bought a tune and can't seem to figure out what is keeping it from revving. The combo is a 5.3 running on a COS5 tune, TH400, MP70 turbo, 2 bar MAP, Boost referenced fuel pressure...

Yes thank you. It does make sense. Maybe I'm misreading his comment. I understood it as he had the MAF calibration set to 0 but it was still throwing a MAF code? That's an issue I've noticed with...

I'm new so I have to ask what MAF killers you're talking about. I'm having an issue as well and I'm trying to find out what I'm missing. I bought a tune as well that isn't working.

I'm having what sounds like the same issue. I'm running a 5.3 with turbo, TH400, COS5, and cable throttle body. It will idle but when I give it any throttle it just dies. Did you happen to find the...

Paul I have good news. I was finally able to get the computer to take a full flash with a known good tune and now the truck runs. Joecar, I ended up buying a bench harness to flash it with. Well...

Paul, I appreciate your help. I bought a bench harness from Speartech. I've been playing with it for a while now and still have not been able to fix the two pcm's that I have. The orange LED is...

I'm not currently set up for bench programming. I'm trying to flash them while in the truck. Should I build a separate bench harness?

Joecar, my connector is wired like so.

Serial Data Pin 2 to Blue Connector Pin 58.
Pin 4 and 5 are wired to a junction block wired to battery ground.
Pin 16 is wired to a junction block wired to...

Well I answered my last question. I bought a used PCM from a S-10 yesterday. Tried a full flash and came up with the checksum error. Now this PCM is having the same problem as the first one. No...

I didn't try this earlier but after work I will try flashing a totally stock tune to see if this failure happens again. What happens if I keep having this problem during a full flash? Will it screw...

I'm just trying to change operating systems. From a 12212156 to a 12205612. Am I not doing this correctly? I tried a full flash. Should I be trying this a different way?

I had this problem with the last pcm as well. I tried doing a full flash and when it was almost done this popped up. Anybody know what causes this?...
