So I have a strange issue. Recently had to install EFILive on a new system, and in V7.5, one user account shows Engine RPM, Intake Manifold Pressure and Intake Air Temperature as invalid/unsupported...

Much appreciation for the response. As far as you know, there is really no workaround? Do you believe it might be the systems I'm using or like a display setting? Not a huge deal if the update...

I am experiencing a weird issue with the Scan Tool in V8 that I've had ever since using it. I was wondering if someone can possibly assist. I took a video of what's going on because I figured it'd...

Make sure all those stupid and frustrating ground wires are good and tight on the back of the driver's side head. If all you did was a port job and slight milling; I can't see the tune being way...

I didn't see any other .mls file other than the one I believe that comes installed with efilive (example.mls). However, your help made it possible for me to just specify what maps I want to use with...

I don't know if this is normal or not, but it sure is frustrating. It seems when I load a PID file, my "Maps" will change to other map configurations that I may have used in the past. Then I have...

Guess it can't hurt to double check. Thanks, Lee. Feel free to drive 25 miles north to Layton and come for a ride with me to see what you think, lol. I appreciate the thought... I'll make sure my...

I'll move those columns to a lower map and try your tune full on tomorrow. The motor is no longer a 98. It's still the 98 block, but I have the good beefy LS2 rods and the 2004 LS6 pistons...

Yes... well almost. I'm going to test one more time by zero'ing out the WOT mph tables just for sanity sake. I left my WOT MPH settings, and nothing changed... it still fails to shift. For some...

Thanks for the responses guys. I've put the transmission tune back to stock and then used the calculator to adjust some of the shift points... I can tweak as necessary if I need to, but the goal is...

Well I'm sick and tired of trying to fight this transmission of mine and I'm sick of it not shifting so I'm here asking if anybody out there might be willing to share a tune that they know WORKS with...

Deeply saddened by the news... my thoughts and prayers are with Shawn's family. Shawn was always quick to offer help and I loved joking with him about the shitty altitude we have to deal with. ...

Alright, I'm going to post my calc_pids.txt file so someone can modify it accordingly and then I can see exactly what it should look like afterwards. My calc_pids.txt is untouched... I've never...

Wow, that post cleared up so much damn confusion. THANKS Shawn. Damn our altitude, huh? Anyways... I really appreciate your help. I'm quickly learning that I need to forget about AFR, and forget...

Alright. I've searched, and have found multiple threads, but I can't grasp this crap, so I have to finally ask for some newbie help. I'm in Utah, and all we have is E10... I did the test thing and...

Verdict is in... fuel pump. Apparently the one I used to replace my original must have been crap. Luckily I paid under $50 for it via eBay... must not have been an OEM pump. Get what you pay for...

Thank you!

Damn, I should have monitored short term fuel trims on the log I did today. I'm going to post two screen shots... one from a log of the truck hot, and one from the truck mostly cooled down. The hot...

I guess the crank sensor signal is in the front of the motor. I believe the cam sensor is on the distributor.



The problem was very minimal for quite some time... then the fuel pump died and I...

UPDATE - Well it's definitely not ignition related... unless it's the distributor itself. I replaced ignition coil, ignition control module, rotor, and distributor cap... no fix. It's getting worse...

Would an air leak in the exhaust be something I could hear (exhaust leak)?? Wouldn't it have to be a pretty big exhaust leak to make it run that bad? I can take a video from inside the truck and...

Yeah, I'm wondering if I have a coil going bad myself. No DTC's or check engine light... check engine light never flashes or anything. It seems to idle just fine, even while hot, but once I get...

Alright... posting up the current and stock tunes. I smoothed VE tables on the current tune, and I did a little tweaking to the transmission tables as well on my current tune; just to firm up the...

Alright... this is not exactly a Gen III problem, but there isn't a lot of activity in the Vortec forum, so I wanted to make the post here. I cannot for the life of me figure out what's wrong with...

Hi Lee,

Very interesting stuff here. I was at the same test & tune with my '98 Camaro. Wish I would have known you were from Utah, I would have tried to track you down. What color is your...
