I'm popping a CEL (light on the dash) but when I try to pull the DTCs in HPtuners nothing shows up. It doesn't say "no DTCs detected".

When I use my cheapy ebay hand scanner it indicates two lean...

Nothing? My HPtuner dash speedo is reading 30 or so while I'm actually going 75.

On another note, my CEL popped but the scan in the logger reveled nothing and didn't say (no CELs detected). Then...

How can I commit changes to tire size and/or gear ratio?

Under my gear/tier calc tab the Current has "error" and the ratio is right. My commit button is grayed out and I can only hit the undo if...

Got it (2.23). Thanks. Things are working. I sat down, watched the vid and redid it to get the gauges where I wanted but you motivated me to get off my butt and get it done.

Thanks,
Frank

rclinton,
Are you running the beta 2.3 of HPtuners? I have 2.2 and it says I can't open the config file because it's newer.

Frank

So can a 2.23 users save in the 2.22 format or do I need to get the 2.23 beta to use this config?

Someone made up a .cfg with dual custom LC1s that I wanted to try but when I opened it it gave me the "Display Configuration failed to load. This file was created with a newer version of the...

Thanks a lot. I programmed the first correctly per that video. When I watched it again I realized that the first LC1 was setup with the defalut value.

I'm not sure at what point I decided to try...

config uploaded.

Will do tonight. I'm at work now.

Someone at LS1tech thought I had the O2B1 and O2B2 front leads switch which makes sense based on the reaction of the O2s but I swapped them and the problem swaps sides.

In the DTC page under the...

I'm trying to add a 2nd LC1 to the other bank. I added the first one a year ago and just used the default LC1 setting under "Wideband" when adding AUX. The instruction PDF indicates to create a...

Swapping bank 1 injectors with bank 2 injectors did nothing.

I've got an LS6 swap in an Miata controlled by an '04 GTO PCM with a vanilla mailorder tune to delete the basics. I figured I'd pick up HPtuners to see what the hell is going on.

The problem is...

Thanks again Bill. I wanted to get the car running with the mailorder tune and then jump into tuning but it looks like I'll at least be messing around somewhat with hptuners while troubleshooting...

Back troubleshooting this again. My B1O2 is still going right down to zero. I'll pull the plugs and assume they're black on B1 side. I removed intake and everything seems intact and tightened...

Quick question. While I assume this leak was cause from my LS6 intake install, could an exhaust leak at the header flange fluctuate the O2 readings this much? My Mustang gearhead neighbor commented...

Thanks. No cam, stock LS6. I'll start hunting for that this weekend. Appreciate the quick response. I did swap O2s and had the same issue on the driver side.

I just finished swapping an LS6 into my Miata. I'm using an '04 GTO PCM. It's got a vanilla mail order tune. I logged the car with the key on and idling, and then driving around the court in 1-2...

Can anyone tell me what parts of the PCM can stop injectors from firing. VATS seems to allow them to fire then stall. I am not seeing that so I doubt it's VATS which I have removed.

What about...

I fixed this problem yesterday. It was a USB driver problem. If you guys go into your Settings->Control Panel click on System then select Hardware->Device Manager and expand the Universal Serial...

Looks like injector pulsewidth isn't doing much while cranking. I pulled the VCM info and VATS was set to PWM. I changed that to none. I read up a bit on VATS and it mentioned the BCM. This is a...

Got the VCM read with full voltage to the battery. Keep it simple stupid!

I'm not noob to forums or computers, but damn I sure am an HPTuners noob.

Installed drivers. Got info from interface to see my 8 credits. Tried to connect and it can't see the VCM.
