Please add a way to disable the vats on V6 cars. We have a 99 olds alero with a bad vats module and need to diable it for the car to run. Is this a possibility?

I would like the limit the MPH Lower to engage PE only after reaching a certain MPH, say like 10-15 MPH.

How about adding a PE vs MPH enable table if you could. It would really help to have a MPH limit as to where the PE can and cannot be enabled. I think this would be the final table needed for PE. ...

I would like to be able to turn off some codes. Sorry if I worded it wrong.

DTC Processing Enablers need to be added. Also, an O2 switch point would be great for MPG tuning.

There are no O2 switch points for the 02/03 envoys and trailblazers. That is quite a big jump in MPG. I think it has more to do with MPH driven and light on the throttle. Just my 2 cents

Make sure your 42lb injectors are rated that way at 48psi. Injector size is based on a given fuel pressure so altering the fuel pressure would change the injector rating.

Yes i have. I have lowered all required tables and could not enter PE any sooner than before modifing the PE tables.

Ok chris, i see that now. Thank you. There must be some other checks in there as well as i cannot enter into PE mode at low rpms with little throttle even while changing the TPS enable %. Must be...

2003 Envoy. I dont think it is in the 2002 file either.

Can this be added to the tuning package? It would be nice to be able to use this to enter PE whenever you want based on load.

Im on vacation in hilton head right now. When i get back i will be putting the Envoy on the Dyno to see what i can drag out of it. I have compared a few envoy/trailblazer tunes so far and they are...

As long as it is the same year and model, then yes.

Where did you get your headers and how much were they? I may be looking for some headers.

I did change some of the camshaft spark and such on mine. The Trans tables made a huge diff in shifting. My truck is much more powerfull at mid range now. It shifts like a dream. Very strong,...

2003 GMC ENVOY SLT, FULLY LOADED. The tune really helped alot. Im sure you could use a tune to fix your fuel smell. Are you using HPT yet? The I6 file is pretty much complete with all the...

Ill try and send it over tonight. It picked up some pretty good power and the shifts are alot stronger than before. Im still working on the fuel thing but it still seems to be around a +2 gain at...

Ive done alot of tuning on my I6 so far and got about a plus 2 miles a gallon with just the TM change and some added spark at crusie. Adjusting the VE will not do anything for fuel millage as i have...

PE VS RPM modifier will work to adjust the afr in wot.

I ordered my MVPI Interface yesterday. I sent them an email today to [email protected] and they have responded within a few hours to let me know that it will be shipping within a few days. So, at...

Any updates on this yet? Just trying to stay up on when it is going to be ready.

Checking in again on I6

How is the progress on the I6 PCM's coming along? Any timeframe yet?

Thanks,
