I meant to tell the OP that. I should've known better since I own an G8. Hey JuanVelez, have you pulled a copy of the tune file from the ECM yet?

DFCO is disabled, in the low kpa areas like 30-40 it's rich 10-15percent. I'm running SD and can't seem to remove enough fuel thru the VE table....

This is exactly my point. One small change in the order you tune and you can be way off. Murfie, CC86 and the HPTuner staff are on point....

Thank you gentleman. I’m just using it for gen 3 stuff. If I ever need to do gen 5 stuff, I’ll update or buy the newer setup.

if the adder was doing anything to stop it its only a 0.09 ms short pulse at the .7ms commanded so its barely there, must be something alse going on...

Here you go. This is a good baseline tune for TVS 17 Auto. Hope it helps

Found some threads saying it can help some. Thanks for the input

I was hoping it would help with decel.

I understand, but is the adder keeping me from going less than 0.7 ms

I generally use the tables to restrict power on blown cars. Comes in very handy with PD blower cars if they are over-pulley'd or experience belt...

I have both EFI & HPT, 95% of my tuning is done with efi as i had that first & am thus more familiar with it's capabilities. Lord knows the scanner...

post your tune for any help

So you used a 04 impala ss pcm in the 01 venture with the l67 and everything works? I thought the 03 and up transmissions used different electronics....

Add some decimal places to your table, you probably find that those are not all zeros.

I am happy to say i can now log in on forum and also log into my HP acct. Thank you.

read the info at the bottom of the page when ur cursor is on that table tab, get it wrong and its not good so most just do small changes if any

short pulse adder just helps the pulse when they are small, it dosnt actually add to the pulse its like a prime time it needs so when it does pulse...

Wait, no... that won't work. Stupid me. It'll still be the same ohms with the float in the same position. If you could mount the sender card...

Mine has the 8 speed 8L90e but with a newer locked tcm. I just wish I could get a direct answer from them if all Hope is being abandoned.

Sounds like your pretty good at repairs. Did you replace the sway bar bushings with the Energy Suspension sway bar link kit about $35 worth every bit...

Glad to hear that. Try graduating the TPS% from 60% at 3000 or so to require less TPS in upper rpm range. Let's face it if you are at 4000 having PE...

you will never make your desired HPFP of 3300psi even if you did your pushing the fuel system to the max. and maxing our SOI doesnt help either

Swap the two sender wires at the pump module. The '01 gauge is expecting to see 250 ohms full/40 ohms empty, '05 reads 40 ohms full/250 ohms empty....

7-8 psi and 17 degrees on timing is the sweet spot for l83, l86, lt1 on 93 octane. Headers, no cats opens up the tuning window for a little more...

I didnt realize the iat was pulling out some timing. I put the timing back to 15ish and fixed the iat to pull timing at 120ish? F im going to...

The L83 in my tahoe is 11:1. I am not running 24? of timing on pump 93. And i have a free meth kit so 15? of timing on this 3.75" pulley is...

So would the other transient values have to be done in a new thread or can we continue working on transient values here? Minimum pulse width adders,...
