Finally did some driving, having issues with the trans not shifting the way it should be, when it first manually, it will not move, we suspect the solenoid so he is changing it...

Fuel changes are good.

Have a weird issue, tcc related, revs fine, idles fine, but when coming to a stop it stays revved up, very noticeable, it only comes down to idle rpm once completely stopped...

I've been told by the owner that it is constant 58psi.

Much appreciated, thank you!!

Been out of the tuning arena for awhile, have to re teach myself a lot! Plus the GP GTP pcm and cobalts were so much straight forward than these!

I am just trying...

Aeromotive a1000 pump and a aeromotive a1000 efi bypass regulator.

Idle psi is 58psi.

I only changed the one table, flow vs kpa.

It's been awhile since I have adjusted fuel stuff.

I...

I have a friend with a Nova that he just finished putting a 6.0L in from a 99? Silverado (not 100% on that)

He has asked me to modify his tune, changes needed are fuel injector change, I...

Which I did, and it worked great all of last year, but I am curious if I should alter it again, is this normal as the sensor gets older? I've never known about this, I figured the offset was good and...

Thanks for the reply, I just don't see why I would have to play with the offset to match the gauge, I didn't want to do this in case the gauge/sensor was bad, I won't be doing any tuning until I have...

Little history first, I run std hptuners, always use latest software version (not beta). I use an aem 30-300 and have it wired through the a/c, worked great last fall, hptuners matched the gauge.
...

I will try the bracket change, but all seems back to normal size I have re-calibrated the sensor.

Thanks!

Everything seems fine with the tune as far as the NB goes, but when I go WOT, it shoots straight to 8 afr, probably would go less but 8 is the limit. I am concerned that this is not accurate...

Is there any information on how the external sensors (wideband for example) hook up to the MPVI2 ?

No difference between STD and PRO hardware? Same price? If not, awesome!

I guess I will look into upgrading my standard cable for a new one!

Will there be an option to upgrade from the standard?

I can understand that, time and $ wasted (side/personal time).

Why not just build per order instead of building an inventory?

I am in for whatever you come up.

Because AEM has come out with an already OBD enabled gauge, do you think they would bother with the 0300? I don't think they would bother, but who knows... HPT on the other hand, would be nice.
...

Is there an ETA?

BTW, thank you for doing this!

I am doing as much as possible, the 3800 GP PCM was so much easier to MAF tune than this so I am relearning a bunch of things.

I'm doing baby steps.

Again, thanks, it much appreciated.

This is the filter I have attached... I used the EQ Commanded, will try it out tomorrow.

Did some scanning, adjusted my MAF a bit and was able to lean it out, a lot, but now I know which way to go.

A scan from a quick drive, much improved, now hopefully the work can begin to straighten the trims out.

Changed upstream 02 sensor, fuel trims are acting normally again, now maybe I can actually tune them properly.

Thanks for the response. I am not sure why it says locked, I checked and says it is unlocked, I will try to upload it again asap.

I figured the LSJ was picky, nothing like a Grand Prix pcm that I...

I am trying tot tune my MAF on my LSJ Cobalt but am really unsure about my config, the LTST + STFT x MAF to be specific.

I have read a bunch of write ups and watched some videos and was confident...
