I have read the SD VE and MAF tuning guide.
Set up my tune as per the instructions.
Just trying to understand the histogram used for logging....

Hey guys....someone please set me straight on this.

I have tuned my MAF.....in OPEN loop, hours of cruising, lambda is 0.96 to 1.01. Never into PE.

PE table is set at 1.136 across the board....

Ok, after playing with the number in the 'Table Display', I have managed to make the Scanner lambda and logworks match.....

Is this accurate, more the less?

Thanks

Alright, I got that to work. However, I am still stuck with how to make the Scanner Lambda = the Logworks lambda reading...

Thanks!!

Hey guys....I have literally hours into researching this...and yet, I am still lost.
I can get the scanner to read AFR. I can get it to read lambda too...but I cannot make the lambda accurate vs....

working!:pray:

working...frustrating though...

Yes, thanks.

Any thoughts on the grams/per cyl only going to a max of 0.60?? Shouldn't it hit like 1.0 at WOT? (this indicating the MAF is way off?)
I multiplied my MAF HZ table by 1.1 and the...

here are some logs and histograms...

Yes guys, sorry I know, very vague...

Mine works,...

Ok, someone please excuse my lack of knowledge with this stuff....

Between 25 to 35 % TPS, I get up 4 to 6 deg KR.
RPM is from about 1700 to 1900.

I can make it do this anytime.

I saw this...

I used a real small rivet.....although it does obstruct the backside of the blade, as it sticks out about 2mm.

Would JB weld stick?

Well guys, it was the hole in the throttle plate. I put a piece of duct tape over the hole and now it runs perfect again!!

Now to figure out how to permanently fix this!

Thanks to you all,...

further to the story...he was just going to replace my TB with another stock TB....that was fine by me. This was 3 months ago in the dead of winter. So no problem to help him out. By luck, when...

I thought about patching the whole with a rivet...but the screws on the blade are 'smoothed' over. I gotta get a hold of a stock TB...

The reasons I have this TB...is during the winter, my...

smithers, I assume you are saying the throttle position hangs due to the tune being off?


I will read how to do the Russ K tune tonight and possibly be able to get it done this week, weather...

smither, the car ran perfect until I put on the ported TB. The idle hangs for about 4 to 8 seconds at a stop before the idle goes down to 1000rpm.

Watching the VCM scanner shows the Throttle...

I did some of the things smithers said to try....still won't idle. It sticks at about 2000rpm if the car is moving and when I stop, it takes about 8 or 10 secs to lower the idle...but it only goes...

Thanks smithers, your help is appreciated!!

This is what I would like to know!! What are the parameters I need to adjust?!

Thanks again!
:worship:

I did not know there was a screw for this? The Corvette is fly by wire.

Hey folks....

99 Vette, 6spd, long tubes, no cats, CAI and a ported stock TB.

My idle is hanging at 2000rpm when rolling and when stopped it takes about 20 seconds to start to come down. If I...

Alright....I haven't used my HPTuners for about 3 months....and during that time, Windows7 must have updated something and now I get this exact same problem when I try to open a file.
I deleted .NET...

NGK vs. Bosch....that I could understand that some 'may' think one is better....
