Thankyou sir

Hello,

I purchased a new unlocked pcm for my 2018 trackhawk from HPtuners.

I've not installed this yet and just twigged that the calibration file I sent in to HPTuners (order #260614) was...

I used to use stand alone data logging for my LS3 VE VXR8, spent some time failing to get it working for the Jeep :)

Last resort of course was to look up on the help pages.....

Are...

After a datalog I can see the stock widebands report as I would expect.

It did cross my mind a little, thanks for confirming :) , perhaps that particular upgrade will mature on the shelf, whilst warranty erodes..........or I can't stand the temptation.

I had to install the bypass loom to pull the tune from 2018 rhd trackhawk.

I can read all the pids for data logging without bypass loom(afaik from the short test drive).

I now have a new...

Did you manage to also pull the tune without the bypass cable ?

Looking through some of the engine data displays the other day, I noticed that at hot idle
AFR sits at ~13.7 which I thought was a bit weird as stoich for petrol is 14.7
I pulled a couple of tunes...

Do you offer hardware support for MPVI Pro in Australia?

As title, does anyone know if it's possible to datalog the injector timing relative to crank position ?

Regards.

Agree?.I would like to understand a bit more about this.
This guy gets talking about effects of changing injector timing and how this can change afr, I don?t know if the timeframes actually support...

Thankyou....all sorted (with a lot of help)....literally a on/off switch !

I think there is a certain aussie tuner glad to see the back of this too!

Hello, have been struggling with this exact issue for months !!! how can I get a beta copy.....or how close is the proper release update please ?

Thankyou for replies. I better not post the tune, it's not mine to publish, as much as I think it's lacking. If there is anything specific to look at
I will. Can post the dyno log if that helps...

Looking at a dyno log for a friend who reports straight line climbing afr from 11.5 @5250rpm to 13.8 @7000rpm

So we're trying to work out why it leans out so bad.

His engine spec is heartbeat...

Guys, thanks for replies.

Hello,
I have a LS3 with supercharger running a 2 bar speed density tune (maf-less) operating system 12624402 -> 1250223

The HO spark table is accross the board 3deg more advanced than the LO...

Hi All,
For any of you guys that have data logged fuel rail pressure, I'm tracking down a lean fueling issue but want to eliminate
fuel pressure as a possible cause. My brief setup is 6.2 v8 with...

Thankyou schpenxel, that seems like a good feature, is that new to v3 or was it also available in v2,24 (I'm using v3)

I have a 2bar tune (using a 3bar map sensor)
I'm looking at the VE table and see that it maxes out at 175kpa , I would have
thought it would max out at ~200kpa. I'm not going to boost more than...

I had similar problem yesterday, down loaded 2.24 and re-installed fixed for me. (might have had something to do
with previousy looking at beta 2.25).....weird.....

Kind of same issue, I loaded beta 2.25 to check out the a/c compressor on/off v rpm table correction (transposed in 2.24), then tried to use 2.24 to connect to my
vehicle and could'nt. Only...

Thanks Bill, I used the contact form, there was no facility to add a file, so will await a reply.
