Spark limit testing

[Chris@HPTuners]

guys,

I have added new parameters to the following calibrations:

12221098
12221096
9382927
9382928
9382957
12206042
12206017
9382938
9382941
12206019
12206035
12222128
12583655
12578485
12583711
12216489
12584719
12586586

Please download the latest 2.1.11 beta and install (email support or PM a mod if you don't have the URL). I emailed everyone who emailed me files.

The new params are on the Spark Advance form. They control the RPM and VSS that spark ramp out occurs before fuel cut. Raising the values should eliminate the ramp out.

If your Cal doesn't appear in the list above and you want to test please email support along with your .hpt file.

Awesome, I'll DL and try later this evening. Thanks Chris!

[Shifted]

Ok Chris, couple questions here...

There are 4 new boxes that I see

RPM - Drive (65535) RPM
RPM - P/N (4000) RPM
VSS - Reverse (26) MPH
VSS - Not Rev (106) MPH

What is the RPM - Drive and RPM - P/N mean exactly? And why is RPM - Drive set to 65535 RPM?

[Mr. Pute]

Didn't work with CALID 12578485. I can see the new options just fine. I changed RPM - Drive to 7000rpm, P/N to 7000rpm, and Not Rev to 150mph.

Here's a log of my lunch run up and down the freeway:
Attachment 731

I didn't get a chance to test out the vss spark limiter.

[zinner]

p/n = park/neutral

[Shifted]

p/n = park/neutral

Yeah, I'm a little brighter than that, I'm wondering what those numbers referred to exactly.

[Chris@HPTuners]

they are spark ramp out points to ramp out the spark before the limiters hit, i guess to make the limiter a bit more friendly. Now ti seems there are yet more limits

I'll find them, it's just a pain that it doesn't seem to be calibrated for most vehicles so we didn't see this one prior to release.

[Mr. Pute]

Thanks for the update Chris.

Also, why isn't my Injector duty % working with the scanner? I'm able to see it just fine on my car with a different type of obd2 scanner. Just curious.

[Chris@HPTuners]

you have to be logging RPM and injector PW for the duty cycle to work. It is calculated not directly read from the PCM.

/me starts begging chris for the update to be applied to his calid!

[WopOnTour]

Thanks for the update Chris.

A specific Duty Cycle PID is actually NOT transmitted at all within the GM data stream. If available, it's totally a tool calculated PID using injector base pulse width and engine speed using the standard formula:
RPM*BPW/1200
HTH
WOT

/me starts humpin chris's leg... pleeeeeeeeeeeeeeeeeeeaaase can I get an update for my calid!

[Mr. Pute]

Any more word on this actually working?!?!

[Rodimus_Prime]

Id say it is I used to notice an instant change of getting richer at 6500 and beyond, now its leaner, like the rest of the powerband seems to follow the rest of the curve, as for power numbers i dont know i dont have a dyno with or without

[Mr. Pute]

Chris/Keith,

Anytime you want to comment on this PLEASE, feel free...

[Bill@HPTuners]

what would you like them to comment on? Is there something still not working I guess?

I posted this a month ago:

I didn't get a chance to test out the vss spark limiter.

Just like I did a month ago, I'm still having limit issues. Nothing has changed even though the Beta 2.1.11 file keeps getting bigger. I'd like to hear an update from the head honchos to make sure they haven't abandoned us.

Oh and my speed limiter is producing the same results.

[Chris@HPTuners]

waiting for test results to come back

email me chris@ and i'll send you config to scan with to help with testing if you don;t mind.
