I had to install 2.24 - it was not a layout issue. There was literally no PID to add for knock retard or commanded AFR. Since 2.24 is no longer supported, I suggest you email support so that they...

Hi all,

I'm not sure how many of you out there are still tuning the jbody platform on the P11 PCM, but if you're running the newest version of HPTuners VCM Scaner, please check if you have knock...

You can disconnect the motor from the harness. Immediately after plugging in the non-ECO fuel pump control module, the codes were gone and never came back. When I returned the car to stock to...

I made 175whp on a 21 psi tune with catless mid pipe, catless downpipe, ZZP FMIC kit, zzp CAI and ported intake manifold. I tuned it. With those mods, I was out of turbo up top (100% wastegate duty...

We can't confirm it's COT protection, but I've noticed on most jbodies, the longer you are in power enrichment, the lower the commanded afr lo res drops.

Yea, it seems like there are a few weird things happening to "older" calibrations with the newer versions of 2.24 that I need to email support about. For example, 2002 jbodies do NOT have a knock...

47382Thanks for the reply. I went ahead and tested it while prepping for the dyno day. It successfully pushed 65 psi fuel pressure when commanded. I'm not sure of the long term implications; but...

I was able to save the negative values by loading an older tune and manually changing the higher load cells rather than making compare values "zero". No harm, no foul. The negative values were...

My stock tune has negative values in the low pedal position MAP A, B and C tables. However, my current version of HPTuners forces them to zero. My version is 2.24.734.

Is this going to be a...

Under the Fuel system tab, we have access to a variety of fuel pressure parameters. On a stock calibration, they are capped at 58 psi. Has anyone raised them above that cap successfully? Is the...

The intake is probably the problem - flow through the MAF is very very important, and from the sounds of your trims, that's likely a big part of the problem.

Also, I'm very interested why everyone...

It's not always misfires that signal you're out of fuel. Log commanded fuel pressure and actual fuel pressure. If the two ever deviate during a wide open throttle pull, you're out of fuel. In some...

What about this one? http://www.courtenaysport.co.uk/engine-rebuild-components-z16lex/info_169.html#Z16LEH. It looks like a complete bolt on set up, but IDK if the bolt pattern and turbine outlet...

Is this an LNF take off system, or a European bolt on with integrated turbine housing like stock? I've contacted like three companies to see if the opel/vauxhaul 1.6/2.0t turbos (some are stock K04)...

That kind of explains a lot - when the car blips one or two degress of total KR at wide open, nothing happens to commanded boost for me. One could assume that if the knock airmass was strictly based...

Thank you so much for looking and posting!! I was hoping you'd chime in adn confirm that one of the parameters in my tune was not "all in". When the weather cooperates, I'll give that a shot.

Ummmm, where did i ever say I wanted 100% access? :doh: All I said was if I follow what Chris himself said to do to achieve a commanded boost limit, and i do NOT achieve that limit, I will contact...

I'm not trying to sound combative or contradictory, but why would the developers tell us how to do things the right way, and then it doesn't work? Admittedly, I haven't messed with it since...

Please see the above post from Chris@HPTuners. That's all I want for the car - there should be...

The most recent log I have is attached. Looks like 16.5psi commanded and achieved, and 18.3 peak MAF lbs/min. Looking at it closely I may have hit my airmass limit of 0.85g/cyl, but only for a...

which cars use E39? If it's the cruze, its a limit of how quickly boost can increase.

I appreciate what you are saying, but the car is achieving the commanded boost. My problem is that it is not commanding high enough boost. Adjusting the WGDC table too high will just result in...

300 in the 100% row for all three maps

If you are referring to using the K04 turbo off of the LNF, make sure to adjust your PE settings very liberally for the first runs as well; it's going to hit super early and hard on a 2.4 with high...

You looked at the second file right? I'll have to check the knock airmass table and the pressure delta table, the duty cycle table shouldn't affect commanded boost, it just needs to be adjusted if...
