98-00 Vortec V8/V6 beta

[HyeSpeeder]

Thank you very much for looking at my tune
Yea there is a big lag on this 454 when i step on the gas.
I turned off all of the torque management and i messed around with the rev limiter dident feel too much of a difference . I did change the pe delay to 0 on a few things i think. So far iam still learing
i welded in a bung so i can install my wideband tomorrow.

Thank again for your help

I can't change your tune and save because I don't have a license for your Suburban. But, here is a list of some things I would change:

On the Engine - Fuel Control - Power Enrich Tab:
Delay RPM to 0
Enable RPM table to all 0
Dealy to 0
TPS vs. RPM Table to 0
Enrichment Time to 1.000

On the Engne - Torque Management Tab:
Spark Retard vs. Torque Reduction all to 0
Torque Loss % vs. Spark Retard all to 0

Try these settings for your engine and log some data. These settings work for me, just make sure they work for you.

[HyeSpeeder]

Yea you can. I have never done it but I know of people tuning full race applications with HPTuners.

[HyeSpeeder]

Yea i know they do but the Vortec does not have as many settings as ls2 or newer truck pcms

the vortec tuning is limited I heard cant do a 2 bar or anything cool

[ElecTech]

Yeah...we are working with a couple of customers to see if we can support them but its very early to tell. If you have access to one that you'd like to run some tests on for us email me at support with your serial number and a link to this thread.

E-mail sent.

My 2000 GMC has a ATI Procharger on it, and I know I can use HPTuners to tune it.

[Keith@HPTuners]

We supported some of the newer vortec trucks for quite a few years now, as they used the same PCM's as the LS1's..

[HyeSpeeder]

yes but the older vortec trucks you guys just started to support, will i be able to tune with 5-10 pounds of boost .
Is there going to be a rtt or a 2 bar for the vortec trucks a custom o/s would be awesome.

Bill, which one below were you replying to?

any future plans for LT1 ?

i take it there is a difference in the 96-97 pcm on the 4.3 blazers?

Thanks!

Specifically Justin99 but anyone that has access to a 96-97 vortec truck(s) so we can test a few things.

Bill I have a 97 C2500 5.7L sitting in my driveway and have been using the software since V1.5.2, so I know my way around it. Send me an e-mail with what ever you want me to try.

[Bill@HPTuners]

Yeah, it doesnt look like we'll be able to come up with a solution for the 96-97 guys anytime soon, thanks for all that volunteered your help.

We are looking into the scanner end of things as I speak.

[bilemke]

Sweet.. Just got my interface today. Read my dad's 2000 4.3 S-10 without any issues. Scanner works great. Getting ready to commit some credits to it... However...

Regarding the post above about scanning Knock Retard in the scanner, any updates on this?

[Chris@HPTuners]

i just added the KR PID to the latest beta, should be ready for download in the next couple of days.

Chris..
