I will be replacing the o2's with the ones mentioned. I got the car on the dyno and the wideband shows 12.9-1 all the way through the band. I am still getting a about 1-2 deg's of KR ( common issue I...

The header is not glowing after a run and I pulled the plugs ( on bank 1 )and they are a nice tan tone. The o2 sensors were bosch replacements. I have a wideband I am about to install, but the bung...

I have been trying to get my tune dialed in and I am still fighting with a lean issue on bank 1. It's a 98' camaro... 6 speed. Mods are:

Prc 5.3 heads ( milled to 59 cc's )
mls gasket
custom cam...

No problem:) ... I did another log after tweaking a few things and I got my timing back, but still can't figure out this lean issue on bank 1 :mad:

- see attached log...

I think, on that table, it will only pull out 6 deg. if the engine temp is over 240+ deg... I am running around 192 deg. It does look like that table is pulling out quite a bit of timing at a low...

Well spoke a little too soon. The O2 sensors smoothed it out a bit and got rid of the heater codes, but now its back to adding 16-17% fuel on bank 1 and 5-7% on bank 2. I have checked all the coil...

Got 2 new 02 sensors and took care of the knock and fuel trims. Thanks guys!!!

Thanks for the feedback, I am going to get the car on a wide band in a few days. The compression is around 11.5:1. It looks like the octane scaler parameter is disabled (b6220)... any reason why this...

I am still running the MAF and I have not copied my high octane table into my low octane table. I did modify my low octance table , a bit, and make another run and logged it. Looks like I am...

I can seem to get off the low octane table. I am seeing a max of 22 deg of timing at WOT. I tried to log the scaler pid and it looks like it isnt coming off the low octane table. Can anyone take a...

So I have the tune pretty close now, but I am still having an issue with how the IAC reacts under low speed turning... i.e. parking, etc. The car is a 98 ls1 6 speed with a custom cam ( 227/228 .....

Joe, you are the man! Turns out I blew the 20A fuse in the distribution center... now I just have to hunt down the short... Thanks again!

So I just replaced my MAF and ran through all the wiring to check for any shorts or breaks and all looks well. Just fired it up and still am getting no MAF freqency on the log and the car will...

I was thinking I had a MAF issue, is there any way to test it? I can get it to read frequency after I reset the pcm, but it throws the p0102 code after a few minutes and don't get a signal...

I am just getting into EFILive and I am trying to figure out the tune that came with my car. It is a 98' 6 speed Z28 and the tune was a mail order done by the previous owner. I think it is a SD tune,...

Unfortunatly I cannot validate any pid's because I cannot connect to the pcm...

The led's do cycle when connected to the obd port...

I will do that after work... Is there any chance I have the wrong obd2 cable? The previous owner said he sent the cable into efilive for a replacement because they thought it was a bad cable... I...

Ok, so I got the connection with the interface cable to work, now for some reason I cannot detect my pcm? In scan tool it shows the interface register than when it goes to detect the pcm, no luck....

Just check, fuse is good. When I plug the cable into the port I am able to press the start/stop logging and it will light up the leds, but I am unable to stop it. Possible bad interface?

It's a new battery. I show 12.8 volts not running. Should there be any leds lit up when you connect the interface to the obd port w/o having a usb connection?

I have just picked up a 98 camaro ls1 that came with efi live. The previous owner said he has had a problem with connecting and now I seem to have the same. I have tried loading all the correct usb...
