Hi
I need help with my tune for road racing. I have it know with no knock and somewhat safe AFR (Ithink) and she runs...

Update
the car ran good yesterday! 1.30 on mosport in traffic and 155mph on the back straight!

...

Well with no maf and that table zeroed out (missed the high rpm disable ) I did try to tune the complete VE table as per all the stickies... but had a lot of difficulty to get the a/f spot on. WOT...

Will do thank you.
I used an AFR error histogram to dial in the VE table and had a lot of difficulty with part throttle tuning. Wot seemed not to bad...

do you think my VE table needs more work?...

I thought I only had to zero out the maf for the ECU ignore it? Missed the high rpm disable:(

Thanks for the tip, ill do that right now. Do i have to redo the VE table again?

Ahhh theres that table! Got it... ill try that thanks. And what if I multiply that section you highlighted with say 1.2 instead of making them all 4.1?

very nice!

Heres one, I have to more upload:yay:

Ive been running the car in time attack this season (5 track days) and its been doing it on and off for a while and gotten worse after the...

Anyone had a chance to look at my log yet?
Both the Main Spark and Spark Knock histograms are showing low g/cyl numbers?

I downloaded the new scanner software last night and it's the same...

Also please take a look at my spark knock histogram settings/readings.

I am sure I screwed something up there but can't figure out what. Those readings can't be right?

Anyone know how much...

please help!
Left bank headers hotter than right! they will actually start to glow if i hold it around 2500rpm 10-15 seconds - right dont get near that hot.

please look at my...

Hi
04C5Z corvette
I made some changes to the idle speed and went to write calibration only...
It suddenly stopped the upload roughly 2mins in so I hit abort and hit write calibration again.
...

I was thinking to zero out the PE table (x 1.0 no added fuel) and use the VE table to dial in my A/F for 14.70 in the lower map readings and ramp it up say 14, 13.5, 13 and finally 12.7 as I go up to...

Got it thanks! That worked out great:)
She has a strong idle at 850rpm and crisp off idle throttle response!

Next question: tuning for road racing...
PE tables?
I spend a lot of time at 60-80%...

I added more info to my 1st post.

Ok i flipped the wires back on the CPS (cam position sensor) and its all good! she is holding a solid idle and no codes... now i can start tuning.
Right of the bat the idle A/F is way lean at idle,...

i have the LS6 map sensor with a modified hold down braket.

bingo! she is runing! you are the best!!!
the map connector was not making a good contact... as soos as i got it to read she fired up...

Thank you for the tip and trying to figure this out with me... it looks like a MAP and Cam sensor problem.
MAP reading stays at 1.45psi - no movement even when it fires... And switching the wires...

done thank you. loaded but still the same problem... I did get a code though: P0342 Cam shaft position sensor circuit low?

Note... the LS2 cam cover i have did not come with the little...
