The Express Van calibrations are available without buying them.

But IIRC a V6 PCM will be short a couple of injector drivers for a V8?

If your customer is getting 8-9 MPG with that rig he should have it fixed first!

If you can do a PCM swap and double mileage? Maybe your wasting your time on forums and need to go to work for GM? ...

He sure was helpful and informative!

At the point where the thread died... wifey should have wrote him a check! Not only for getting his car tuned but for the Tuning lessons he got! :worship:

So what was changed? Just curious... I've seen a few that were nothing but a PE Rape.

The only software/hardware to flash the 97 and 97 Vortec Black Box is TunerCat OBDII.

Not only are you setting codes the fluctuating rear O2 sensors are messing with your fuel trims to 10%...

Free file for a paid customer?

Well he started in 2002...

Weld in a new bung for the LC-1, don't use the simulated NB.

Innovate has said not to run one AD output to two sources.

The narrow band O2 sensor does not adjust to AFR, it adjusts to Stoich of the fuel being burned. Lambda is that reading of exhaust and 1.0 is a perfect Stoich.

So if you have E10 fuel which is...

Yes the wideband reads Lambda and converts it to 14.7 to 1 AFR for your viewing pleasure.

Narrow band O2 sensors adjust to Stioch = Lambda on your WB gauge.

What I was trying to say about NB O2...

With the software I use yes. Last I looked at adding HPTuners to the mix had some major issues with changing VINs, had to match OS and year?. Since most swaps and transplants don't match YMM to OS it...

Would he be able to program in his vehicle VIN to the new tune?

Compare the two files and find the differences.

Does the harsh bang into gear have idle raised?

I'm still stuck on six month old E85 fuel... filling the tank just keeps all the water in bottom. Pull your filter and try not to spill any. Pour it all in a glass jar and let it settle. How big a...

If warmed up and in Closed Loop the O2 sensor voltages should swing back and forth.

I know .120 is low but I've seen this a lot when they are not hot enough to work because they are WAY rich and...

2% is not a lot but I think I found your LTFT issue. I'm only on HP demo and not familar with this OS and use another couple programs so correct me if I'm wrong here.

E 10 fuel in most states says...

You guys are having to much fun! I may have to lease one of these for awhile... :pray:

That looks like the 2 I described earlier! :worship:

Usually the big cam is an issue at idle for all sorts of reasons. One is O2 sensor Proportional gains, without it it's impossible to tune idle Closed Loop. "Base proportional O2 gain for engine...

I haven't found it either in HP Demo. Was thinking of purchasing HP Tuner since many parameters like this are missing from EFI Live. Other's like O2 sensor high and low to go with switch points,...

In Closed Loop there is a delay from the time fuel trims are adjusted till the O2 sensor reads again. If you move the O2 sensor 2 feet? Well the STFT Vs airflow delay needs to be increased or it...

The only way to accuratly know is to test the fuel... which I have done all around my local and it all has 10%

Stoich for gas is 14.7 AFR. Stoich for Ethanol is ~9.00AFR. That means that Stoich...

Yeah but I feel like an idiot! It's not like I'm new to PCs... anyway the issue was some security software I had, that is gone, but had changed permissions on red/write to folders!

I really like...

Your not going to beleive this but I just tried to load this software, same download in same computer as this entire thread is about... and it works!

I can't believe I'm going to try this again on a new laptop I just got. But I am so fed up with my EFI Live mistake I'm seriously considering trying your software. but I can't even get it to install?...
