Never mind. I was reading the code with the built in code reader on the vette. I just found out that all p03xx codes show up as p0300. You have to use a code reader to get the individual cylinders...

I am getting the code p0300. It seems to run ok till it warms up and then the misfires start. I am not getting any other codes. Is there a way to tell which cylinders are misfiring????

This has...

The LC1 has two outputs. One is widband and the other is narrow band. I just replaced my OEM one with the LC1 and put the GM plug on the narrowband side. It then just plugs into the OEM wire harness....

Most people get a pig tale that will just plug into where the old narrow band went and use the 12 volts there to power the wideband. Makes it easy to just unplug and put your old narrow band back if...

Bring ALL of the grounds for the LC-1 to one terminal lug. I attached it to the ground lug on the frame just inboard of the battery on my 2000 Corvette. I also wired up Analog 1 to simulate my narrow...

I put mine in the stock O2 bung and ran the output to my EGR valve input on the pcm. No wires to run that way. It also simulates the narrow band.

Thank you sir.

PS Just a reminder that a software dyno would be great!!!

How about a single button to copy the appropriate cells from the primary VE table to the secondary one on the engines that have the secondary. My 2000 Corvette would appreciate it.

I was trying to fine tune my VE tables using STFT's. I had gotten them pretty close but one last change. I could not get back out to see what the change had done for about 2 hours. In that time the...

Found it. I had forgotten to set the closed loop enable temps to 250.

I can upload cfg files but when I try and upload either an hpt or and hpl file it just hangs. The files are less than 400kb so I do not know what is going on.

When I try and upload the hpt and hpl files, it just hangs. I can upload the cfg file. I checked and they are less than 400kb. Is anyone else having this problem????


Reb

I did. Both of those are set.

I am trying to tune via Wideband and have disabled LTFT and STFT. When logging I notice that all of the LTFTs are 0 as I would expect. The STFTs are still regestering even though I...

I was considering upgrading the OS on my vette to a 2002 version. Would this burn my existing credits?? If so, is there a way to retrieve them to use after the OS upgrade????

...

Ok, after looking at it some more, on the standards tune log, I see the EGR voltage changing all over the place like it should. I am feeding the output of the LC-1 into the EGR on the pcm. On the...

I have a 2000 Corvette that I just had the motor rebuilt in. The rebuild included a mild Comp cam, Comp valve spring, and port and polish of the heads. I have recently purchased HPTuners along with...

I beleive that the 6.25 you stated should be .625 ( 5/8 ). That assumes that you are setting the LC1 to 10-18 AFR.

If you have not programed the LC1 yet, I beleive that it comes set for 8 - 22...

Can anyone tell me where I can find the female connector pin for a PCM on a 2000 Corvette. I am trying to hook up a wide band to the empty EGR pin. I beleive that it is an 18 gage pin.

Thanks

On mine, the pre-cats are before the first O2 sensor. The pipes do not merge at all. There is an H pipe after the main cats. The pre-cats are only about 1 foot from the exhaust manifold.

I have a 2000 Corvette with a freshly rebuilt motor. ( cam , port , etc. ) I have purchased HP tuners but I have a question about a wideband sensor. This is a California car so it has small pre-cats...
