Thanks for the info, I downloaded the bluecats calculator. Do these settings look accurate? I'm not sure if "Shift Lead Time" is the right way to modify the full throttle upshifts and downshifts?

I've got 2014 Caprice with a mild cam and a converter from a LSA CTSV. I'm trying to get a decent baseline tune, still learning how to tune a 6l80e. Would it be a good idea to copy some trans...

Ah cool, nice to know. After I figure out this fan issue I'll play around with these settings a little.

Good to know! I was pretty confused but that explation makes perfect sense, thank you

Here's my tune file.

As far as relays go, I don't believe this car has any for the cooling fans. They're controlled by a PWM fan controller that gets constant hot and ground and is controlled by...

My radiator fans won't turn on in my stock 2014 Caprice 6.0L. I'm wanting to command both fans on to troubleshoot the problem. But when I look at VCM Scanner's fan controls I see options to turn on...

Well, it's definitely a problem with the 2 bar OS. Flashed it back to the stock OS and it's reading the WBO2 perfectly with no other changes. I guess the 2 bar OS modifies something with how the PCM...

I got the 2 bar OS loaded and it seems to be running good after coping over my VE table and entering the 1 bar MAP settings. I do have one problem though. I log my AEM Uego through the EGR input,...

Good deal, thank you! Looks like the 1 bar settings are 94.43 linear and 10.33 offset. I've been tuning off that little secondary VE table for a couple days and it's a couple days too long lol. ...

Would I have problems changing to the 1998 SD 2 bar OS (1250120) on an NA setup with the stock 1998 MAP sensor? I'm not boosted, and don't plan to be, but I prefer to tune in SD and the stock '98...

Am I just very dense, or is my gear/tire wizard broken? This is on a 1998 z28 file I've licensed. One box is grayed out and if I input any values into the other box i get ERR in the multiplier box....

Just to update this thread I found the problem. The 12v wire under the fuel tank hat that goes to the fuel pump had burned through its insulation and was exposed. It also got hot enough to burn...

Good call, I found 3 on the driver's side head and they all had very little resistance going back to the battery.

Just to see if the alternator is causing the problem I removed the serpentine...

As many as I could find. Checked the grounds right near the battery, the alt ground strap, and engine and chassis grounds. Having some trouble finding where the sensor and PCM grounds are though.

Any ideas?

I'm fighting some high idle and drivability issues, when I took a log I noticed my control module voltage was over 16v and TPS voltage at idle was around 1.5v. When I manually checked the voltage...

I think you're right, I'll ask around and see if any of my friends have a scope to test it with. It seems like testing AC voltage, especially with my HF multimeter, isn't really going to tell me...

It sounds like you've made some assumptions that weren't right in the past, and you're making assumptions again so let me clear this up and be as specific as I can be. Milliamps was a simple typo,...

I'm thinking I probably wasn't reading the AC voltage correctly. I was using a harbor freight voltmeter and on my other cars I'm also reading around 30, so the reading is similar amoung other cars...

No, sorry I wasn't clear. The wire goes from the alternator to some crap stereo amp the previous owner installed. I pulled the fuse that was making contact with the ground and everything is back to...

Say you have a power wire coming off the alternator and is fused with a large blade 30 amp fuse. If the top of said fuse touched a sensor ground bolt, would that cause this problem? If so, I think my...

I'm getting right around 30.8v AC with the car running. Is that in the acceptable range? Little dark out but I'm going to try and pull the alt wire and see if there's any change.

Got my hands on another 98 PCM and it has the same problem. High voltage fuel sender circuit, high control module voltage, and high TPS voltage. Really stumped now. I'm not too sure what to test...

Dang, was hoping that wasn't the case. I was thinking back about what could've caused this and I remembered let the car sit and the battery died. I hooked it up to a cheap Harbor Freight battery...

This is on a 1998 z28 M6 with bolt ons and BTR stage two NA cam. Do you know what would cause the control module voltage get 17v at idle when my battery and alternator are putting out about 14.5v? ...
