I actually ran into this problem in my C5, that is already run in OLSD.

I was driving home one night, and 35 miles from home when the car started running terrible, i was data logging at the time...

We have the complete LS1 stream, for 97-98 and 99+ unlocked, and they still will not connect to some 97-98 PCM's

Yes, we have experienced this quite a few times

We have 2 V2's and 1 V1, and 2 laptops with EFI Live software.

We have had quite a few 98 LS cars that could not be read with either of our V2's,...

You could run 12.5's if you get that 60 foot down.

ET's are not a measure of Horsepower (for the most part), trap speeds are

IMO get that 60 foot down in the 1.6-1.7 range and you will be alot...

Trapping 105 in an non stalled A4 with those mods is not to far off, which means the Horsepower is not bad.

My guess is the issue is more in your 60 foot then in the tune :)

Can you give some more details please?

What year model car, what mods? Auto, manual? What gears. And lastly, what trap speed? This is a much better indicator to the state of your tune then your ET...

Beer, so whats it gonna take to talk you into a few suny day's in Florida :cheers:

Hello!

One thing that has bothered me a little bit about the new 7.5+ versions of EFI Live is the change that was made to the analog input calibration window. You used to have a test button...

Hello

Meant to give you a call today, sorry we missed your call. Give us a call tomorrow, and ill try to get ahold of you as well. We have done quite a few of these for F-Bodys and Corvettes...

Unfortunetaly, i have only owned V2's, so i am not familiar with the V1 Input cal procedure, otherwise i would be more then happy to share it with you. I do Know that it can and should be done,...

Still have to call the V1, its a bit of a lengthier process using a bit of Math and re-writing some code, but its doable :)

My first thought then is your wideband calibrated properly to your EFI LIve unit?

We use LC1's, and we noticed early on that the digital output (logworks) was varrying quite a bit from what EFI...

We did a 440TT c5 a few days ago with the 79# racetronix's injectors, just a base tune for idle so he could run it for a 30 minute break in period, it settled right into idle at 800RPM with a few...

If you had the car running fine with VE, then tuned the MAF you were already out of speed density, do you mean you tuned the VE, then Did the Maf, all was good then you turned fuel trims on and it...

I guess i dont understand why you want to lower the fuel pressure, those injectors are not hard to tune at 58psi, is there another reason that is going over my head?

That failure will not affect your TC lockup, can you post up your tune maybe we can see whats going on?

If you cannot command the TCC to lock even with BIDI, i would start checking the wires for...

First thing i would check is the accuracy of the LC-1 as EFI Live is reading it,

Start the car up and start scanning, pull up logworks as well. Does EFI Live (LC-1 analog out) show the exact same...

yes, but drilling it bigger is a backyard beaver way of trying to make it idle correctly. If the tuner would take the time to set the IAC counts, running air flow and throttle cracker/follower...

Agreed, i'd stop taking advice from any tuner who told you to drill a hole in the TB...

You can real time adjust any parameter in the cal, some use RTACS and make the adjustments for you, some you input yourself but its all done in real time

Post up your tune file for sure, that will help us help you.

The dip in your idle when coming to a stop, could be throttle cracker, or it could just be your VE is off at idle, it will do that if...

If your running the original PCM in your 01 Z06, you should be able to use COS5 just fine.

try turning idle learning off and see what happens?

Man bruce, i coudnt have described my problems any better then you have here n this thread, i am getting the EXACT same conditions as you.

Dont forget you'll need to calibrate the V2's analog inputs for the ground offset of the LC-1. This will fix the problem of having any kind of split between the LC-1 digital out reading (as seen in...
